Triamcinolone is a synthetic glucocorticoid that is considered slightly more potent than prednisone when given orally. Triamcinolone is commercially available in nasal, parenteral, topical, intravitreal injection, and suprachoroidal injection formulations. Topical preparations for corticosteroid-responsive dermatoses are considered to be of medium or high potency and are used topically to relieve the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. Triamcinolone has little mineralocorticoid activity and is therefore not used systemically to manage adrenal insufficiency unless a more potent mineralocorticoid is administered concomitantly. While triamcinolone may be used for many inflammatory conditions, triamcinolone injection suspensions are commonly employed for intralesional or intra-articular use when such therapy is indicated. Triamcinolone nasal spray is used to manage symptoms of seasonal and perennial allergies. Rhinitis guidelines strongly recommend intranasal corticosteroids as the preferred medication when choosing monotherapy for persistent allergic rhinitis; they may also be offered as first-line therapy for nonallergic rhinitis (NAR) although intranasal antihistamines are strongly recommended as a first-line monotherapy option for NAR. An intravitreal dosage form is used in ophthalmic conditions unresponsive to topical ophthalmic corticosteroids and to aid visualization during vitrectomy, and a suprachoroidal injection is used to treat macular edema associated with uveitis.
Discontinuation and shortage of Aristospan:
In order to address a shortage of Aristospan injection suspension, the FDA is allowing Hexatrione injection suspension to be imported into the U.S. Hexatrione is not FDA approved. It is important to note that there are key differences between Aristospan and Hexatrione, such as the imported Hexatrione is packaged as a 2 mL ampule with a total strength of 40 mg/2 mL (20 mg/mL) compared to Aristospan that was available as a 1 mL vial with a total strength of 20 mg/mL. Hexatrione should not be diluted prior to administration. Do not use filter needles to remove the Hexatrione suspension from the ampule, as filter needles can remove important active ingredients suspended in the vehicle. Do not use any ampule that shatters upon opening or that is contaminated with glass after opening. Hexatrione is only indicated for intraarticular administration.
General Administration Information

Route-Specific Administration
Oral Administration
Other Oral Formulations
Oral dental paste (e.g., Oralone)
-Apply at bedtime to permit steroid contact with the lesion throughout the night. In some cases application may be needed 2 or 3 times per day. Apply after meals.
-Press a small dab (about 0.5 cm) to the lesion until a thin film develops. A larger quantity may be required for coverage of some lesions.
-For optimal results use only enough to coat the lesion with a thin film. Do not rub in. Attempting to spread this preparation may result in granular, gritty sensation and cause it to crumble. After application, however, a smooth, slippery film develops.
Injectable Administration
-Triamcinolone acetonide or hexatonide injection suspensions are for intramuscular, dermal lesional, or intra-articular injection only. Follow the specific product instructions, as some injections are only formulated for specific routes. Do NOT administer intravenously.
-Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit.
Intramuscular Administration
-Triamcinolone acetonide may be administered by IM injection.
-Inject deeply into a well-developed muscle. Rotate sites of injection.
Other Injectable Administration
Intra-articular, intrasynovial, intrabursal, soft-tissue, intralesional, or sublesional injection suspensions (e.g., Kenalog-10, Kenalog-40, Aristospan)
-Triamcinolone acetonide may be administered by intra-articular, intrasynovial, intralesional, or soft tissue injection. Indicated routes of administration vary by formulation. Ensure the correct product has been chosen for use.
-Triamcinolone hexacetonide may be administered by intra-articular, intralesional, or sublesional injection.
-Use strict aseptic technique.
-To ensure a uniform suspension, shake vials well before use. Prior to withdrawal, the suspension should be inspected for clumping or granular appearance (agglomeration). An agglomerated product results from exposure to freezing temperatures and should not be used.
-After withdrawal from the vial, inject without delay to prevent settling of the injection in the syringe.
-Administration of triamcinolone via these routes require specialized techniques. Only clinicians familiar with these methods of administration and with management of potential complications should administer triamcinolone by these routes.
Intra-articular triamcinolone hexacetonide injection suspension (i.e., Hexatrione 2% only)
-Hexatrione is not FDA approved; in order to address a shortage of Aristospan, the FDA is allowing Hexatrione to be imported into the U.S.
-There are key differences between Aristospan and Hexatrione:
--Hexatrione is labeled as 40 mg per ampule (20 mg/mL) and the product is packaged as a 2 mL ampule with a total strength of 40 mg/2 mL; each mL contains 20 mg of triamcinolone hexacetonide. Aristospan was available as a 1 mL vial with a total strength of 20 mg/mL.
-Hexatrione does not have a barcode and therefore the product must be manually entered into institution systems.
-Hexatrione SHOULD NOT be diluted before injection.
-Hexatrione is a suspension of milky white appearance with no apparent crystalline formation
-Hexatrione is supplied via an auto-breakable pre-scored One Point Cut (OPC) ampule. OPC ampules can be opened easily and safely, reducing the risk of splintering and/or sharp edges.
-DO NOT use a filtered needle to remove Hexatrione suspension from the ampule; filter needles can remove important active ingredients that are suspended in the vehicle.
-DO NOT use the medicine if the ampule shatters or if the opened ampule is contaminated with glass after opening. As with other ampules, there is a risk for glass pieces to enter the suspension if the glass shatters or splinters upon opening of the ampule. Thus, it is important to utilize proper breaking technique when opening the ampule.
-This formulation is not suitable by inhalation by nebulizer.
Preparation:
-Use strict aseptic technique. Shake the ampule before use.
-DO NOT use the medicine if your ampule shatters or if the opened ampule is contaminated with glass after opening. As with other ampules, there is a risk for glass pieces to enter the suspension if the glass shatters or splinters upon opening of the ampule. Thus, it is important to utilize proper breaking technique when opening the ampule.
-Opening the OPC ampules without an ampule opener:
--Pick up the ampule and hold its lower part between your thumb and index finger. Make sure to remove all the liquid from the top of the ampule by gently tapping it with a finger of the other hand.
-Hold the ampule so that the colored dot faces you.
-Grasp the top of the ampule with your other hand. Place your thumb onto the colored dot and the index finger on the opposite side (back) of the bulbous part of the ampule. Pressure between the index finger and the thumb of either hand can cause the ampule to break in an unintended manner and may cause injuries.
-Hold the bottom of the ampule firmly in an upright position and push the top section away from the colored dot with light, even pressure. The ampule should break with a clean snap. Using too much force can cause the ampule to shatter. If the ampule shatters, discard it and use a new ampule.
-Always apply pressure away from the colored dot, never in any other direction. Avoid any pushing, pulling, or twisting actions while applying pressure on the ampule to open it. To prevent shattering of the glass, never try to break ampules with force.
-If the ampule does not break open, readjust its position in your hands and try again. If it seems extremely hard to open, do not try to open it by force. Try with a different ampule or use an ampule opener.
-Opening the OPC ampules without an ampule opener:
--Pick up the ampule and hold its lower part between your thumb and index finger. Make sure to remove all the liquid from the top of the ampule by gently tapping it with a finger of the other hand.
-Hold the ampule so that the colored dot faces you.
-With your other hand, slip the ampule opener over the top of the ampule right into the neck below the bulbous part.
-Grasp the ampule opener with your thumb and index finger placed on opposite sides on the indicated area close to the ampule neck and make sure that the dot on the ampule is still in position under your thumb.
-Hold the bottom of the ampule firmly in an upright position and push the top section away from the colored dot with light, even pressure. The ampule should break with a clean snap. The ampule top may jump out of the opener when the ampule snaps open.
-Using too much force can cause the ampule to shatter. If the ampule shatters, discard it and use a new ampule.
-Always apply pressure away from the colored dot, never in any other direction. Avoid any pushing, pulling, or twisting actions while applying pressure on the ampule to open it. To prevent shattering of the glass, never try to break ampules with force.
-DO NOT use a filtered needle to remove Hexatrione suspension from the ampule; filter needles can remove important active ingredients that are suspended in the vehicle.
-It is recommended to use a needle bore gauge between 19 and 25. Viscosity of the suspension is a major factor in needle size selection. The active molecule is less than 260 microns so a 23 g or 25 G needle with internal diameters ranging from 337 to 260 microns would suffice, however, the pull becomes more difficult with the smaller 25G needle.
Administration:
-Administer intra-articular; do not inject into the soft tissue or via intradiscal injection.
-Avoid superficial injection due to risk of skin atrophy.
Intra-articular triamcinolone acetonide extended-release microsphere injection suspension (i.e., Zilretta only)
-Administer as a single intra-articular injection.
-Do not use in small joints, such as the hand. Intended for use in the knee.
-Administration of this injection requires specialized techniques. Only clinicians familiar with intra-articular administration and with management of potential complications should administer this injection.
-Use strict aseptic technique and the diluent supplied in the single-dose kit.
-Grip the top of the triamcinolone powder vial and tap firmly and repeatedly to dislodge all powder from the vial and stopper.
-Attach vial adapter to the triamcinolone powder vial.
-Withdraw 5 mL of diluent into a syringe. Attach the syringe onto the vial adapter and transfer the diluent.
-With the syringe still attached to the vial, mix by tapping the vial firmly and repeatedly in a circular motion and swirl gently for at least 1 minute.
-A properly mixed suspension will be milky white, contain no clumps, and move freely down the vial wall.
-Swirl gently for at least 10 seconds. Withdraw the full contents (32 mg) from the triamcinolone vial into the syringe, and remove the syringe from the vial adapter.
-To ensure the powder is suspended, gently invert the syringe several times prior to administration.
-Administer the entire contents of the syringe using usual technique for intra-articular injection. Promptly inject after preparation to avoid settling of the suspension. Discard any excess suspension in the vial immediately following injection.
-Storage: If needed, the suspension may be stored in the vial for up to 4 hours of ambient conditions. The syringe must remain on the vial adapter while the suspension remains in the vial.
Intravitreal injectable suspension (Triesence or Trivaris)
-Triamcinolone acetonide injectable suspension may be administered by intravitreal injection.
-Administration via this route requires specialized techniques. Only clinicians familiar with intravitreal administration and with management of potential complications should administer triamcinolone by this route.
-Administration should be done with strict adherence to aseptic technique.
-Administer adequate anesthesia and a broad-spectrum microbicide prior to the injection.
-For Triesence: Prior to administration, shake vial vigorously for 10 seconds to ensure uniform suspension. Inspect the suspension for agglomeration prior to withdrawal; do not use if agglomerated. Once withdrawn, use immediately to prevent the suspension from settling in the syringe.
-For Trivaris: Attach a 27-gauge half-inch needle to the syringe, and advance the plunger to the single line marked on the prefilled glass syringe shaft. Hold the syringe and the needle at an angle and express excess gel suspension over a sterile surface. The plunger is correctly positioned to provide the recommended dose of 4 mg/0.05 mL when white compound is no longer visible between the plunger and the fill line on the syringe. Always check the needle to ensure that it is firmly attached to the syringe before injecting the patient.
-Each vial or syringe is for the treatment of a single eye. If both eyes require treatment, use a new vial or syringe; before administration to the other eye, change the sterile field, syringe, gloves, drapes, eyelid speculum, filter, and injection needles.
-After the intravitreal injection, monitor patients for elevation in intraocular pressure and for endophthalmitis. Monitoring may consist of a check for reperfusion of the optic nerve head immediately after the injection, tonometry within 30 minutes after the injection, and biomicroscopy 2 to 7 days after the injection. Instruct patients to promptly report any symptoms suggestive of endophthalmitis.
Suprachoroidal injectable suspension (Xipere)
Preparation:
-Remove the tray from the carton. Examine the tray for damage. Ensure the sealed compartment cover of the tray is intact and undamaged. Do NOT use if damage is present.
-Remove the vial from the tray and examine it to ensure there is no evidence of damage.
-Peel off the compartment cover exposing the sterile tray.
-Each tray contains the following:
--A SCS Microinjector syringe with vial adapter attached
-A 30-gauge x 900 micrometer needle
-A 30-gauge x 1,100 micrometer needle
-A single-dose vial of triamcinolone acetonide injectable suspension 40 mg/mL
-Grasp and hold the long sides of the tray and invert the tray. Squeeze gently to release the sterile tray onto the appropriate sterile preparation surface.
-Vigorously shake the vial for 10 seconds. Inspect the vial for clumping or granular appearance of the sterile contents. Do NOT use if clumping or granular appearance is present.
-Immediately after shaking the vial, pick up the syringe and ensure the vial adapter is securely attached. Handle the syringe by the clear barrel during the connecting, filling, and disconnecting processes. Do NOT add additional air into the syringe prior to connecting the vial adapter to the vial.
-Use aseptic technique to connect the vial to the vial adapter by pushing the spike of the vial adapter straight through the center of the vial septum until is snaps securely in place.
-Invert the entire assembly so that the vial is directly above the syringe. Slide the white plunger handle all the way back and forth multiple times to fill the entire syringe with suspension and to remove any remaining air. The white plunger handle has a stop to prevent complete removal of the plunger from the syringe.
-While holding the vial adapter and vial, disconnect the syringe by twisting off the adapter. Retain the vial with the vial adapter connected in the event re-access is necessary.
-Connect the 900 micrometer needle to the syringe. Ensure the connection is secure. At the discretion of the physician, the longer needle may be used.
-While holding the syringe barrel with the needle pointing up, expel air bubbles and excess drug by aligning the plunger with the 0.1 mL mark on the syringe.
-Once the dose has been prepared, perform the suprachoroidal injection without delay in order to prevent settling of the drug.
Administration:
-Must be administered using the SCS Microinjector under controlled aseptic conditions, which includes the use of sterile gloves, drape, eyelid speculum (or equivalent), and cotton swab.
-Prior to the injection, apply adequate anesthesia and a broad-spectrum microbicide to the periocular skin, eyelid, and ocular surface.
-Identify the injection site by measuring 4 to 4.5 mm posterior to the limbus using the tip of the needle cap or ophthalmic calipers.
-Remove the needle cap to expose the needle. Holding the syringe perpendicular to the ocular surface, insert the needle through the conjunctiva into the sclera. Ensure the hub of the needle is firmly against the conjunctiva, compressing the sclera to create a dimple on the ocular surface. Maintain the dimple and perpendicular positioning throughout the injection process.
-Gently press the white plunger handle to inject the drug over 5 to 10 seconds. Movement of the plunger will be felt as a loss of resistance and indicates that the needle is in the correct anatomical location for suprachoroidal administration. If resistance is felt and the plunger does not advance, confirm the hub is in firm contact with the conjunctiva creating a dimple and that the syringe is perpendicular to the ocular surface. Small adjustments in positioning may be needed.
-Maintain the hub against the eye for 3 to 5 seconds after the suspension has been injected.
-Slowly remove the needle while holding a sterile cotton swab next to the needle as it is withdrawn. Immediately cover the injection site with the swab. Hold the swab on the injection site with light pressure for a few seconds.
-In cases of continued resistance during the injection process:
--Remove the needle from the eye and examine the eye for any issues. If the safety of the patient is not at risk, a new injection procedure may be started at a new injection site adjacent to the original site.
-If resistance continues, remove the needle from the eye and, if patient safety is not at risk, consider changing to the other needle in the sterile tray. Repeat the preparation and injection process with the new needle.
-Immediately after the injection, monitor for elevations in intraocular pressure. Appropriate monitoring may consist of a check for perfusion of the optic nerve head or tonometry.
-Appropriately discard all drug products and components (used or unused). Each tray and its components are single-use only, and should only be used for the treatment of 1 eye.
-Instruct patients to promptly report any symptoms suggestive of endophthalmitis or retinal detachment (e.g., ocular pain, ocular erythema, photophobia, blurred vision).
Topical Administration
Cream/Ointment/Lotion Formulations
Cream or ointment
-Wear gloves for application if required by universal precautions.
-Apply a thin film and rub gently into the cleansed, slightly moist affected area.
-The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive unless directed by the prescriber. Occlusive dressings may be necessary for psoriasis or severe or recalcitrant conditions.
-Wash hands before and after use.
Other Topical Formulations
Topical aerosol spray
-Spray an affected area for about 2 seconds at a distance of approximately 7.5 to 15 cm. The 2-second spray will be sufficient to cover an area of skin about the size of the hand.
-May use the spray tube provided to help reach hard to treat areas like an area of the scalp. Wash the tube after each use.
-Keep away from the eyes and mucous membranes. If used near the face, care should be taken to see that the eyes are covered, and that inhalation of the spray is avoided.
-The spray is flammable; avoid heat, flame or smoking when using this product.
Inhalation Administration

-While sniffing gently, spray the prescribed or recommended number of sprays into the nostril.
-Repeat steps for the second nostril.
-After using, gently wipe the nozzle with a tissue and replace the cap.
-Do not blow the nose for 15 minutes after use.
-To avoid the spread of infection, do not use the inhaler for more than 1 person.
The most common adverse reactions with nasal triamcinolone therapy (more than 2% incidence) during clinical trials were pharyngitis, epistaxis, flu-like syndrome, cough increased, bronchitis, tooth disorder, pharyngolaryngeal pain, and naso-pharyngitis. Nasal septum perforation has been reported rarely in patients receiving intranasal glucocorticoids. Possible adverse respiratory and nasopharyngeal effects following nasal inhalation of triamcinolone include flushing, xerostomia (dry mouth), nasal dryness, cough, epistaxis, dysphonia (hoarseness), nasal irritation, and dysgeusia. During clinical trials of triamcinolone acetonide extended-release injection suspension, sinusitis or cough were reported in 2% of patients (n = 424) who received a single intra-articular injection compared to 1% with placebo.
Pharmacologic doses of systemic corticosteroids, such as triamcinolone, administered for prolonged periods can result in physiological dependence due to hypothalamic-pituitary-adrenal (HPA) suppression. Generally, HPA suppression is not observed with inhaled triamcinolone alone but is theoretically possible at high doses. Additionally, use of inhaled corticosteroids with systemic corticosteroids could increase the likelihood of HPA suppression compared to a therapeutic dose of either one alone. Systemic absorption of topical corticosteroids can also produce reversible HPA suppression with possible adrenocortical insufficiency after withdrawal of treatment. Percutaneous absorption of triamcinolone is dependent on many factors including the vehicle, the integrity of the epidermal barrier, duration of use, and use of an occlusive dressing. Children may be more susceptible to systemic toxicity from equivalent doses due to their larger skin surface to body mass ratios. Manifestations of adrenocortical insufficiency in children include low plasma cortisol concentrations and absence of response to adrenocorticotropin (ACTH) stimulation. HPA axis suppression has been reported in children receiving topical corticosteroids. Increased intracranial pressure has also been reported in children receiving topical corticosteroids. Increased intracranial pressure with glucocortiocoids usually occurs after treatment. Clinical signs of increased intracranial pressure include bulging fontanelle, head pain/ache, and bilateral papilledema (i.e., pseudotumor cerebri). Patients applying triamcinolone to a large surface area or to areas under occlusion should be evaluated periodically for evidence of HPA axis suppression (using the ACTH stimulation test, A.M. plasma cortisol test, and urinary free cortisol test). To minimize risk of HPA axis suppression, discontinue therapy when control is achieved. If no improvement is seen within 2 weeks, reassessment of diagnosis may be necessary. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, reduce the frequency of application, or substitute a less potent corticosteroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the topical corticosteroid. Exogenously administered corticosteroids exert a negative feedback effect on the pituitary, inhibiting the secretion of ACTH. This results in a decrease in ACTH-mediated synthesis of endogenous corticosteroids and androgens by the adrenal cortex. The severity of secondary adrenocortical insufficiency varies among individuals and is dependent on the dose, frequency, time of administration, and duration of therapy. Systemic administration drug on alternate days may help to alleviate this adverse effect. Patients with HPA suppression will require increased doses of corticosteroid therapy during periods of physiologic stress. Acute adrenal insufficiency and even death can occur with abrupt discontinuation of therapy. Discontinuation of prolonged oral corticosteroid therapy should be gradual since HPA suppression can last for up to 12 months following cessation of therapy. Patients may continue to need supplemental corticosteroid treatment during periods of physiologic stress or infectious conditions, even after the drug has been discontinued. A withdrawal syndrome unrelated to adrenocortical insufficiency can occur following sudden discontinuance of corticosteroid therapy. This syndrome includes symptoms such as appetite loss, lethargy, nauseousness, head pain/ache, fever, joint pain, muscle pain, exfoliative dermatitis, loss of weight, and hypotension. These effects are believed to be due to the sudden change in corticosteroid concentration rather than to low corticosteroid levels.
Prolonged systemic triamcinolone therapy can adversely affect the endocrine system, resulting in hypercorticism (Cushing's syndrome including fat abnormalities such as buffalo hump and moon face), hirsutism, menstrual irregularity, or alterations in motility and number of spermatozoa in susceptible patients. Postmenopausal bleeding (vaginal bleeding similar to a menstrual period) has been reported in postmarketing experience, but causality has not been determined. In some patients, systemic absorption of topical corticosteroids may produce manifestations of Cushing's syndrome. Percutaneous absorption of triamcinolone is dependent on many factors including the vehicle, the integrity of the epidermal barrier, duration of use, and use of an occlusive dressing. Children may be more susceptible to systemic toxicity from equivalent doses due to their larger skin surface to body mass ratios.
Because of retardation of bone growth, children receiving prolonged systemic triamcinolone therapy may have growth inhibition. Controlled clinical trials have shown that intranasal corticosteroids may also cause growth inhibition in pediatric patients; linear growth retardation has also been reported in pediatric patients after prolonged use of topical corticosteroids. Growth inhibition has been observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA) suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients. With orally inhaled corticosteroids, the mean reduction in growth velocity is approximately one centimeter per year (range 0.3 to 1.8 cm per year) and appears to be related to the dose and duration of exposure. Prolonged use (e.g., more than 1 year) of high doses of inhaled corticosteroids, especially when used in combination with frequent courses of systemic corticosteroids, may increase the risk of adverse growth effects. The long-term effects of this reduction in growth velocity, including the impact on final adult height, are unknown. To minimize the effects, each patient should be titrated to the lowest effective dose.
Glucocorticoids, such as triamcinolone, are responsible for protein metabolism, and prolonged therapy can result in a negative nitrogen balance and various musculoskeletal manifestations including myopathy (myalgia, muscle wasting, muscle weakness or myasthenia), arthralgia, tendon rupture, bone matrix atrophy (osteoporosis and osteopenia), bone fractures such as vertebral compression fractures or fractures of long bones, and avascular necrosis of femoral or humeral heads. These effects are more likely to occur in older or debilitated patients and with systemic use. Even inhaled glucocorticoids have been associated with decreased bone mineral density and osteoporosis in very rare cases, particularly with prolonged use. Glucocorticoids interact with calcium metabolism at many sites, including decreasing the synthesis by osteoblasts of the principal proteins of bone matrix, malabsorption of calcium in both the nephron and the gut, and reduction of sex hormone concentrations. Although all of these actions probably contribute to glucocorticoid-induced osteoporosis, the actions on osteoblasts are the most important. Glucocorticoids do not modify vitamin D metabolism. Patients should be monitored for signs of osteoporosis during prolonged corticosteroid therapy. Intra-articular injections of corticosteroids can cause Charcot-like arthropathy, calcinosis, and post-injection flare and atrophy at the site of injection has been reported following administration of soluble glucocorticoids. Joint swelling (3%) and contusions (2%) were reported among 424 patients during clinical trials with intra-articular use of triamcinolone acetonide extended-release injection suspension, and in a study evaluating repeat intra-articular injection after week 12, there were higher rates of reported mild to moderate arthralgia after the second dose (16%) than after the first dose (6%). Arthralgia, joint swelling or effusion, muscle spasm, septic arthritis, and leg pain have been reported with postmarketing intra-articular use of triamcinolone acetonide extended-release injectable suspension.
Among intranasal triamcinolone recipients, diarrhea (3%), upper abdominal pain (4.7%), and dyspepsia (3.4%) were noted as gastrointestinal (GI) effects occurring at incidences higher than with placebo. Adverse GI effects associated with long-term systemic or inhaled triamcinolone administration include nausea, vomiting and anorexia with subsequent weight loss. Appetite stimulation with weight gain, diarrhea, constipation, abdominal pain and/or distention, esophageal ulceration, hiccups, gastritis, and pancreatitis also have been reported. Peptic ulcers with possible subsequent GI bleeding and GI perforation have been reported with long-term corticosteroid therapy. Although it was once believed that corticosteroids contributed to the development of peptic ulcer disease, in a review of 93 studies of corticosteroid use, the incidence of peptic ulcer disease was not found to be higher in steroid recipients compared to control groups. While most of these studies did not utilize endoscopy, it is unlikely that corticosteroids contribute to the development of peptic ulcer disease.
Corticosteroid therapy including triamcinolone can mask the symptoms of infection and should generally be avoided during an acute viral, fungal, or bacterial infection. The incidence or course of acute viral or bacterial infection, however, is probably minimally affected by nasal corticosteroids in immunocompetent individuals. The most common potentially infectious-related adverse reactions with nasal triamcinolone use (more than 2% incidence) were flu-like syndrome and bronchitis. Influenza or a flu-like syndrome was reported in 8.4% of pediatric patients treated with intranasal triamcinolone in clinical trials. Localized candidiasis of the nasal mucosa and pharynx occurs frequently with intranasal corticosteroid therapy. If such an infection develops, the corticosteroid should be discontinued and appropriate local or systemic therapy initiated. Periodically examine patients using intranasal triamcinolone for evidence of infection. Leukocytosis is a common physiologic effect of systemic corticosteroid therapy and may need to be differentiated from the leukocytosis that occurs with inflammatory or infectious processes. Immunosuppression from corticosteroids is most likely to occur in patients receiving high-dose (e.g., equivalent to 1 mg/kg or more of prednisone daily), systemic corticosteroid therapy for any period of time, particularly in conjunction with corticosteroid-sparing drugs (e.g., troleandomycin) and/or concomitant immunosuppressant agents; however, patients receiving moderate dosages of systemic corticosteroids for short periods or low dosages for prolonged periods may also be at risk. Corticosteroid-induced immunosuppression may result in the activation of latent viral (e.g., herpes) or bacterial (e.g., tuberculosis) infections and should not be used in patients with an active infection except when appropriate anti-infective therapy is instituted concomitantly. Patients receiving immunosuppressive doses of corticosteroids should be advised to avoid exposure to measles or varicella (chickenpox) and, if exposed to these diseases, to seek medical advice immediately. Monitoring systemic corticosteroid recipients for signs of opportunistic fungal infection is recommended, as cases of oropharyngeal candidiasis have been reported. Development of Kaposi's sarcoma has also been associated with prolonged administration of corticosteroids; discontinuation of the corticosteroid may result in clinical improvement. Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects, especially if used in excessive dosage, over large body surface areas, for prolonged periods, or with occlusive dressings. In the presence of dermatological infections, institute the use of an appropriate antifungal or antibacterial agent. If a favorable response does not promptly occur, discontinue the topical corticosteroid until the infection has been adequately controlled.
A rash (unspecified) was noted in 2.5% of intranasal triamcinolone recipients as compared with 1.7% of placebo recipients during clinical trials. The following adverse reactions (listed in decreasing order of occurrence) are reported with topical corticosteroids such as triamcinolone and may occur more often when used with an occlusive dressing: skin irritation (including burning), pruritus, xerosis (dry skin), folliculitis, hypertrichosis, acneiform rash/eruptions, skin hypopigmentation, perioral dermatitis, maceration of the skin or oral mucosa, secondary infection, skin atrophy, atrophy of the oral mucosa, striae, and miliaria. Erythema, telangiectasia, purpura, and maculopapular rash may also occur. Although skin atrophy usually occurs after prolonged use of topical corticosteroids, this effect may occur even with short-term use on intertriginous or flexor areas, or on the face. If irritation develops, discontinue topical corticosteroids and institute appropriate therapy. The anti-inflammatory activity of topical corticosteroids may also mask manifestations of infection. In the presence of dermatological infections, institute the use of an appropriate antifungal or antibacterial agent. If a favorable response does not promptly occur, discontinue the corticosteroid until the infection has been adequately controlled. Various adverse dermatologic effects reported during systemic corticosteroid therapy include skin atrophy, diaphoresis, acne vulgaris, striae, acneiform rash, alopecia, xerosis, lupus-like symptoms, perineal pain and irritation, purpura, rash (unspecified), telangiectasia, facial erythema, petechiae, ecchymosis, pruritus, and easy bruising. Hypersensitivity reactions may manifest as allergic dermatitis, urticaria, pruritus, rash, anaphylactoid reactions, and/or angioedema. Postmarketing reports of anaphylactoid reactions have rarely been associated with the use of triamcinolone inhalations. Parenteral corticosteroid therapy has produced burning or tingling in the perineal area, skin hypopigmentation, skin hyperpigmentation, scarring, and other types of injection site reaction (e.g., induration, delayed pain or soreness, subcutaneous and cutaneous atrophy, and sterile abscesses).
In general, excessive use of systemic or topical corticosteroids can lead to impaired wound healing. Triamcinolone should not be applied directly on or near healing wounds. Use of intranasal triamcinolone is not recommended until healing has occurred for patients who have experienced recent nasal septal ulcers, nasal surgery, or trauma; use of nasal corticosteroids may rarely cause nasal ulceration or nasal septal perforation. Skin ulcer may develop in patients with markedly impaired circulation who use topical corticosteroids.
Prolonged administration of systemic triamcinolone can result in edema and fluid retention due to sodium retention; electrolyte disturbances (hypokalemia, hypokalemic metabolic alkalosis, hypernatremia, hypocalcemia); and hypertension. In a review of 93 studies of corticosteroid use, hypertension was found to develop 4 times as often in steroid recipients compared to control groups. In another study, an increased risk of heart failure was observed for medium-dose glucocorticoid use as compared with nonuse. At the beginning of the study, patients were at least 40 years of age and had not been hospitalized for cardiovascular disease. Medium exposure was defined as less than 7.5 mg daily of prednisolone or the equivalent given orally, rectally, or parenterally.
Systemic corticosteroids are a common cause of drug-induced hyperglycemia. In the hospital setting, there is evidence that more than 50% of the patients receiving high-dose systemic steroids develop hyperglycemia, with many more having at least 1 episode of hyperglycemia or a mean blood glucose of 140 mg/dL or greater. Long-term use produces metabolic and endocrine effects that include insulin resistance that may lead to new diagnoses of diabetes mellitus (DM) in patients without a history of hyperglycemia or DM prior to corticosteroid use. Glucosuria (glycosuria) and aggravation of existing DM may also occur. Hyperglycemia has been reported in patients with diabetes during postmarketing intra-articular use of triamcinolone acetonide extended-release injectable suspension. Nasal and topical corticosteroids have also been reported to cause hyperglycemia and glucosuria in some patients, but these are relatively uncommon when used for limited durations. Percutaneous absorption of triamcinolone is dependent on many factors including the vehicle, duration of use, the integrity of the epidermal barrier, and use of an occlusive dressing. Children may be more susceptible to systemic absorption with topical use due to their larger skin surface to body mass ratios.
Adverse neurologic effects have been reported during prolonged systemic triamcinolone administration and include insomnia, vertigo or dizziness, restlessness, amnesia and memory impairment, increased motor activity, impaired cognition, paresthesias, ischemic peripheral neuropathy, malaise, ischemic peripheral neuropathy, seizures, neuritis, and EEG changes. Mental disturbances, including depression, anxiety, euphoria, personality changes, emotional lability, delirium, dementia, hallucinations, irritability, mania, mood swings, schizophrenic reactions, withdrawn behavior, and psychosis have also been reported; emotional lability and psychotic problems can be exacerbated by corticosteroid therapy. Arachnoiditis, meningitis, paresis, paraplegia, and sensory disturbances have occurred after intrathecal administration. Serious neurologic events, some resulting in death, have been reported with epidural injection of corticosteroids. Specific events reported include, but are not limited to, spinal cord infarction, paraplegia, quadriplegia, cortical blindness, and stroke. Headache may occur with use of intranasal triamcinolone or other intranasal steroids. Headache was reported in 5% of patients treated with suprachoroidal injections of triamcinolone acetonide (Xipere) during clinical trials and during postmarketing use of triamcinolone acetonide extended-release injectable suspension.
Ocular effects such as corneal perforation, posterior subcapsular cataracts, retinopathy, or ocular hypertension can result from prolonged use of systemic corticosteroids and could result in glaucoma or ocular nerve damage including optic neuritis. Temporary or permanent visual impairment including blurred vision and blindness has been reported with corticosteroid administration by several routes of administration. If injectable systemic steroid therapy is continued for more than 6 weeks, monitor intraocular pressure. Evaluate any patient who develops visual impairment or changes in vision during corticosteroid therapy for ocular hypertension or other ocular adverse effects. Postmarketing reports of cataracts and glaucoma have rarely been associated with the use of triamcinolone intranasal sprays. The risk of cataracts increases with long-term and high-dose inhaled corticosteroid use. The mechanism of corticosteroid-induced cataract formation is uncertain but may involve disruption of sodium-potassium pumps in the lens epithelium leading to accumulation of water in lens fibers and agglutination of lens proteins. Ocular hypertension and cataracts have also occurred following prolonged application of topical corticosteroids to the skin around the eye. Secondary fungal and viral infections of the eye (ocular infection) may occur. Investigate the possibility of fungal infection if patients have persistent corneal ulceration. After intravitreal injection with triamcinolone acetonide injectable suspension (Triesence or Trivaris), monitor patients for ocular hypertension and endophthalmitis. Increases in intraocular pressure, lasting up to 6 months, and cataract progression have been observed in 20% to 60% of patients after treatment. Appropriate monitoring and management of intraocular pressure and optic nerve head perfusion are needed. Monitoring may consist of a check for perfusion of the optic nerve head immediately after the injection, tonometry within 30 minutes following the injection, and biomicroscopy between 2 and 7 days after the injection. The increased intraocular pressure caused by triamcinolone is usually managed by topical glaucoma therapy, but patients may require aggressive non-topical treatment. After intravitreal injection, infectious culture-positive endophthalmitis was reported at a rate of 0.5%, and infectious and noninfectious endophthalmitis was present in less than 2%. Instruct patients to immediately report any symptoms suggestive of endophthalmitis. Less common reactions occurring in up to 2% of patients receiving intravitreal triamcinolone include exophthalmos, hypopyon (leukocytosis in the anterior chamber of the eye), blurring and transient discomfort upon injection, retinal detachment, optic disc vascular disorder, ocular inflammation, ocular hemorrhage, and visual impairment (including vitreous floaters). Ocular adverse events reported in patient receiving suprachoroidal injections of triamcinolone acetonide (Xipere) during clinical trials included increased intraocular pressure or ocular hypertension (6% to 14%), ocular pain (3% to 12%), cataract (7%), vitreous detachment (5%), injection site pain (4%), conjunctival hemorrhage (4%), reduced visual acuity (4%), xerophthalmia (3%), photophobia (3%), vitreous floaters (3%), uveitis (2%), conjunctival hyperemia (2%), punctate keratitis (2%), conjunctival edema (2%), chalazion (meibomian cyst) and meibomianitis (2%), anterior capsule contraction (2%), ocular irritation (2%), ocular pruritus (2%), ptosis (2%), photopsia (2%), and blurred vision (2%).
Hypercholesterolemia, atherosclerosis, fat embolism, sinus tachycardia, palpitations, bradycardia, syncope, vasculitis, necrotizing angiitis, thrombosis, thromboembolism, and phlebitis, specifically, thrombophlebitis have been associated with injectable triamcinolone therapy. Systemic glucocorticoid use appears to increase the risk of cardiovascular events such as myocardial infarction, left ventricular rupture (in persons who recently experienced a myocardial infarction), angina, angioplasty, coronary revascularization, stroke, transient ischemic attack, cardiomegaly, arrhythmia exacerbation and ECG changes, hypertrophic cardiomyopathy (in premature infants), congestive heart failure and pulmonary edema, cardiac arrest or cardiovascular death. As determined from observational data, the rate of cardiovascular events was 17 per 1,000 person-years among 82,202 non-users of glucocorticoids. In contrast, the rate was 23.9 per 1,000 person-years among 68,781 glucocorticoid users. Furthermore, the rate of cardiovascular events was 76.5 per 1,000 person-years for high exposure patients. After adjustment for known covariates by multivariate analysis, high-dose glucocorticoid use was associated with a 2.56-fold increased risk of cardiovascular events as compared with nonuse. At the beginning of the study, patients were at least 40 years of age and had not been hospitalized for cardiovascular disease. High glucocorticoid exposure was defined as at least 7.5 mg daily of prednisolone (or equivalent) given orally, rectally, or parenterally whereas medium exposure was defined as less than the above dosage by any of the 3 routes. Low-dose exposure was defined as inhaled, topical, or nasal usage only.
Cases of elevated hepatic enzymes (usually reversible upon discontinuation) and hepatomegaly have been rarely associated with systemic corticosteroid receipt such as triamcinolone.
Allergic contact dermatitis with topical corticosteroids such as triamcinolone is usually diagnosed by observing a failure to heal. Appropriate diagnostic patch testing may help with the diagnosis.
Tolerance may occur with the prolonged use of topical triamcinolone formulations. Tolerance is usually described as a decreased acute vasoconstrictive response to the agent after a period of days to weeks. This may explain the dramatic responses noted initially by patients early in topical corticosteroid treatment and an apparent diminished response with time. Tolerance is reversible and may be attenuated by interrupted or cyclic schedules of application of triamcinolone creams or ointments for chronic dermatologic conditions.
Corticosteroids may decrease serum concentrations of vitamin C (ascorbic acid) and vitamin A, which may rarely produce symptoms of vitamin A deficiency or vitamin C deficiency. Some loss of folic acid may also be caused by corticosteroid use; glossitis may be noted.
When using triamcinolone injections, ensure correct formulation selection and the proper route of administration to be used, as there are many dosage forms available. Triamcinolone acetonide or hexacetonide injections should never be given via intravenous administration. Triamcinolone 2% injectable suspension (Hexatrione) should never be injected into the soft tissue or via intradiscal injection. Triamcinolone acetonide injection is not recommended for epidural administration or intrathecal administration. Reports of serious medical events, including death, have been associated with intrathecal or epidural routes of corticosteroid administration. Epidural administration of corticosteroids should be used with great caution. Rare, but serious adverse reactions, including cortical blindness, stroke, spinal cord infarction, paralysis, seizures, nerve injury, brain edema, and death have been associated with epidural administration of injectable corticosteroids. These events have been reported with and without the use of fluoroscopy. Many cases were temporally associated with the corticosteroid injection; reactions occurred within minutes to 48 hours after injection. Some cases of neurologic events were confirmed through magnetic resonance imaging (MRI) or computed tomography (CT) scan. Many patients did not recover from the reported adverse effects. Discuss the benefits and risks of epidural corticosteroid injections with the patient before treatment. If a decision is made to proceed with corticosteroid epidural administration, counsel patients to seek emergency medical attention if they experience symptoms after an injection such as vision changes, tingling in the arms or legs, dizziness, severe headache, seizures, or sudden weakness or numbness of face, arm, or leg. The Triesence product is specifically indicated for intravitreal administration only and Xipere is indicated for suprachoroidal administration; other formulations of triamcinolone acetonide injections are NOT indicated for intraocular use. Triamcinolone acetonide extended-release injectable suspension (Zilretta) is only indicated for intra-articular use in the knee.
Triamcinolone is contraindicated in any patient with a known hypersensitivity to the medication or any component of the formulation. Although true corticosteroid hypersensitivity is rare, it can occur and cross-hypersensitivity to other corticosteroids is possible. It is advisable that patients who have a hypersensitivity reaction to any corticosteroid undergo skin testing, which may help to determine whether hypersensitivity to another corticosteroid exists. Such patients should be carefully monitored during and after the administration of any corticosteroid.
Prolonged administration of pharmacological doses of systemic, nasal, inhaled or topical corticosteroids (resulting in systemic absorption) may result in hypothalamic-pituitary-adrenal (HPA) suppression and/or manifestations of Cushing's syndrome in some patients. Adrenal suppression and increased intracranial pressure have been reported with the use and/or withdrawal of various corticosteroid formulations in pediatric patients. Acute adrenal insufficiency and even death may occur following abrupt discontinuation of systemic therapy. In addition, a withdrawal syndrome unrelated to adrenocortical insufficiency may occur following sudden discontinuation of corticosteroid therapy. These effects are thought to be due to the sudden change in glucocorticoid concentration rather than to low corticosteroid concentrations. Withdraw prolonged systemic corticosteroid therapy (duration of treatment more than 2 weeks) gradually. HPA suppression can last for up to 12 months following cessation of systemic therapy. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the topical corticosteroid. HPA-suppressed patients may need supplemental corticosteroid treatment during periods of physiologic stress, such as post-surgical stress, acute blood loss, or infectious conditions, even after the corticosteroid has been discontinued. Encourage patients currently receiving chronic corticosteroid therapy or who have had corticosteroids discontinued within the last 12 months to carry identification advising the need for administration of corticosteroids in situations of increased stress. Conditions that increase systemic absorption of topical corticosteroids include use over large surface areas, prolonged use, use in areas where the epidermal barrier is disrupted (i.e., skin abrasion), and the use of an occlusive dressing. Pediatric patients may absorb proportionally larger amounts of topical corticosteroids compared to adults due to a larger skin surface to body mass ratio and, therefore, may be at increased risk of systemic adverse reactions. Evaluate patients receiving large doses of triamcinolone applied to a large surface area periodically for evidence of HPA axis suppression and/or manifestations of Cushing's syndrome. If these effects are noted, attempt withdrawal of the drug, a reduction in the frequency of application, or substitution of a less potent corticosteroid. Nonprescription intranasal corticosteroids should not be used for greater than 2 months in pediatric patients without oversight of a healthcare provider. If signs of HPA suppression occur with the use of intranasal corticosteroids, the drug should be slowly discontinued.
Potential adverse effects of chronic corticosteroid therapy should be weighed against the clinical benefits obtained and the availability of other treatment alternatives. Prolonged systemic corticosteroid therapy can lead to osteopenia, osteoporosis, vertebral compression fractures, aseptic necrosis of femoral and humoral heads, and pathologic fractures of long bones secondary to decreased bone formation, increased bone resorption, and protein catabolism in any patients. A high-protein diet may alleviate or prevent the adverse effects associated with protein catabolism. The elderly, post-menopausal, and pediatric patients may be more susceptible to the effects on bone. Chronic systemic triamcinolone therapy may cause growth inhibition in pediatric patients due to hypothalamic-pituitary-adrenal axis suppression and inhibition of bone growth. Corticosteroids should be titrated to the lowest effective dose. Because bone development is critical in pediatric patients, monitoring is warranted in patients receiving high-dose or chronic corticosteroid treatment. Growth inhibition may also occur with intranasal or topical triamcinolone due to systemic absorption, particularly in susceptible patients or when used in high doses or for prolonged periods of time. Use of the lowest effective dose is recommended to minimize the occurrence of systemic adverse effects. Monitor growth routinely.
Patients receiving high-dose (e.g., equivalent to 1 mg/kg or more of prednisone daily) or systemic corticosteroid therapy, such as triamcinolone, for any period of time, particularly in conjunction with corticosteroid sparing drugs (e.g., troleandomycin) are at risk to develop immunosuppression; however, patients receiving moderate dosages of systemic corticosteroids for short periods or low dosages for prolonged periods also may be at risk. Treatment with topical or inhaled corticosteroids lessens the risk of immunosuppression; although localized effects may be seen in some patients. When given in combination with other immunosuppressive agents, there is a risk of over-immunosuppression. Intra-articularly injected corticosteroids are systemically absorbed and may cause immunosuppression. Advise patients to contact their health care provider if they develop fever or other signs or symptoms of infection. Joint infections may also occur with intra-articular injection of triamcinolone acetonide extended-release suspension. Avoid injection of triamcinolone into an infected site. Local injection of a corticosteroid into a previously infected joint is not usually recommended. Examine any joint fluid to exclude a septic process. Injection into unstable joints is generally not recommended.
If surgery is required, patients should advise their physician that they received prolonged systemic or inhaled corticosteroid therapy, such as triamcinolone, within the last 12 months and state the disease for which they were being treated. For systemic therapy, identification cards that include disease state, type and dose of corticosteroid, and physician should always be carried with the patient. Most triamcinolone injection products are long-acting preparations, and are not suitable for use in acute stress situations. To avoid drug-induced adrenal insufficiency, a supportive corticosteroid dosage may be required in times of stress (such as trauma, surgery, or severe illness) both during treatment with with these injections and for a year afterwards.
Corticosteroids may increase the risks related to infections with any pathogen, including viral, bacterial, fungal, protozoan, or helminth infection. The degree to which the dose, route and duration of corticosteroid administration correlate with the specific risks of infection is not well characterized, however, with increasing doses of corticosteroids, the rate of occurrence of infectious complications increases. Corticosteroids may also mask some signs of current infection. In general, do not use corticosteroids in patients with systemic fungal infections; corticosteroids can be administered to these patients when necessary as long as appropriate therapy is administered simultaneously. Avoid the use of triamcinolone in patients with a fungal infection or bacterial infection that is not adequately controlled with anti-infective agents. Activation of latent disease or exacerbation of intercurrent infection due to pathogens such as Amoeba, Candida, Cryptococcus, Mycobacterium, Nocardia, Pneumocystis, or Toxoplasma can occur in patients receiving systemic corticosteroids. Rule out infection with latent or active amebiasis before initiating corticosteroid therapy in patients who have spent time in the tropics or who have unexplained diarrhea. Use corticosteroids with caution in patients with known or suspected Strongyloides (threadworm) infestation as the immunosuppressive effects may lead to disseminated infection, severe enterocolitis, and sepsis. Corticosteroids should not be used in patients with cerebral malaria.
Reserve systemic corticosteroid therapy in active tuberculosis for patients with fulminating or disseminated disease and only in conjunction with appropriate antituberculosis therapy. Reactivation of tuberculosis may occur in patients with latent tuberculosis or tuberculin reactivity; close observation for disease reactivation is needed if corticosteroids are indicated in such patients. Furthermore, chemoprophylaxis is advised if prolonged corticosteroid therapy is needed. The incidence or course of acute bacterial infection are probably minimally affected by inhaled or nasal triamcinolone. Application of topical corticosteroids to areas of infection, including tuberculosis of the skin, should be initiated or continued only if the appropriate antiinfective treatment is instituted. If the infection does not respond to the antimicrobial therapy, the concurrent use of the topical corticosteroid should be discontinued until the infection is controlled.
Advise patients receiving immunosuppressive doses of systemic corticosteroids to avoid exposure to persons with a viral infection (i.e., measles or varicella) because these diseases may be more serious or even fatal in immunosuppressed patients. Instruct patients to get immediate medical advice if exposure occurs. If exposed to chicken pox, prophylaxis with varicella-zoster immune globulin may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin may be indicated. The incidence or course of acute viral or bacterial infection are probably minimally affected by inhaled or nasal triamcinolone. Application of topical corticosteroids to areas of infection, including dermatologic fungal infection, and cutaneous or systemic viral infection (e.g., herpes infection, measles, varicella), should be initiated or continued only if the appropriate antiinfective treatment is instituted. If the infection does not respond to the antimicrobial therapy, the concurrent use of the topical corticosteroid should be discontinued until the infection is controlled. Use ophthalmic triamcinolone acetonide injectable suspension (Triesence) with caution in patients with ocular herpes infection because of possible corneal perforation. Avoid the use of corticosteroids in active ocular herpes infection due to the risk of corneal perforation.
Do not use high doses of systemic corticosteroids such as triamcinolone for the treatment of traumatic brain injury. An increase in early mortality (at 2 weeks) and late mortality (at 6 months) was noted in patients with head trauma who were determined not to have other clear indications for corticosteroid treatment; in the trial, patients received methylprednisolone hemisuccinate. Most triamcinolone injection products are long-acting preparations, and are not suitable for use in acute situations.
Corticosteroid therapy, including systemic triamcinolone therapy, has been associated with left ventricular free-wall rupture in patients with recent myocardial infarction, and should therefore be used cautiously in these patients. As sodium retention with resultant edema and potassium loss may occur in patients receiving systemic corticosteroids, these agents should be used with caution in patients with congestive heart failure, hypertension, or renal disease or insufficiency.
Systemic corticosteroids, such as triamcinolone, may decrease glucose tolerance, produce hyperglycemia, and aggravate or precipitate diabetes mellitus. This may especially occur in patients predisposed to diabetes mellitus. When corticosteroid therapy is necessary in patients with diabetes mellitus, changes in insulin, oral antidiabetic agent dosage, and/or diet may be required. Topical corticosteroids should be used with caution in patients with diabetes mellitus, as increased blood glucose and exacerbation of diabetes has occurred. Use of topical corticosteroids may further delay healing of skin ulcers in diabetic patients.
An acute myopathy has been observed with the use of high doses of systemic corticosteroids, most often occurring in patients with neuromuscular disease disorders (e.g., myasthenia gravis), or in patients receiving concomitant therapy with neuromuscular blocking drugs. This acute myopathy is generalized, may involve ocular and respiratory muscles, and may result in quadriparesis. Elevation of creatinine kinase may occur. Clinical improvement or recovery after stopping corticosteroids may require weeks to years.
Existing emotional instability or psychosis may be aggravated by corticosteroids. Psychiatric derangements may appear when corticosteroids are used, ranging from euphoria, insomnia, mood swings, personality changes, and severe depression, to frank psychosis. Use triamcinolone with caution in patients with a seizure disorder; systemic steroids can lower the seizure threshold.
Metabolic clearance of corticosteroids is decreased in hypothyroidism and increased in hyperthyroidism. Changes in thyroid disease status of a patient may necessitate an adjustment in systemic triamcinolone dosage.
Systemic corticosteroids should be used with caution in patients with active or latent peptic ulcer disease, diverticulitis, fresh intestinal anastomoses, and nonspecific ulcerative colitis, since steroids may increase the risk of a gastrointestinal (GI) perforation. Signs of peritoneal irritation following GI perforation in patients receiving corticosteroids may be minimal or absent. Corticosteroids should not be used in patients where there is a possibility of impending GI perforation, abscess, or pyogenic infection. There is an enhanced effect due to decreased metabolism of systemic corticosteroids in patients with severe hepatic disease with cirrhosis.
As with any long-term topical treatment of the nasal cavity, patients using nasal triamcinolone over several months or longer should be examined periodically for possible changes in the nasal mucosa. Further, because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal septal perforation or ulcer, nasal surgery, or nasal trauma should not use a nasal corticosteroid until healing has occurred.
Topical corticosteroids should be used for brief periods, or under close medical supervision in patients with evidence of preexisting skin atrophy. Elderly patients may be more likely to have preexisting skin atrophy secondary to aging. Purpura and skin lacerations that may raise the skin and subcutaneous tissue from deep fascia may be more likely to occur with the use of topical corticosteroids in older adult patients. The use of lower potency topical corticosteroids also may be necessary for some patients. Topical corticosteroids may cause impaired wound healing of non-infected wounds, such as venous stasis ulcers. Use topical triamcinolone preparations with caution in patients with markedly impaired circulation or peripheral vascular disease; skin ulceration has been reported in these patients following topical corticosteroid use. Further, because of the inhibitory effect of corticosteroids on wound healing, patients who have experienced recent nasal septal perforation or ulcer, nasal surgery, or nasal trauma should not use nasal triamcinolone until healing has occurred.
Topical corticosteroids, such as triamcinolone, should not be used to treat acne vulgaris, acne rosacea, or perioral dermatitis as they may exacerbate these conditions.
Use systemic, nasal, intravitreal, and suprachoroidal corticosteroids with caution in patients with glaucoma; corticosteroids can cause increased intraocular pressure with possible damage to the optic nerves. If steroid therapy is continued for more than 6 weeks, intraocular pressure should be monitored. The use of corticosteroids may produce posterior subcapsular cataracts and may enhance the establishment of secondary ocular infection due to bacteria, fungi, or viruses. Treatment with suprachoroidally administered triamcinolone (Xipere) is contraindicated in patients with active or suspected ocular or periocular infections, including most types of viral disease or infection of the cornea and conjunctiva such as herpes simplex virus epithelial keratitis, vaccinia, varicella, and mycobacterial infection of the eye and fungal diseases. Corticosteroids should not be used in active ocular herpes simplex because of possible corneal perforation. The use of systemic corticosteroids is not recommended in the treatment of optic neuritis and may lead to an increase in the risk of new episodes. The use of triamcinolone injections, except for Triesence, by intravitreal administration is not recommended. Endophthalmitis, eye inflammation, increased intraocular pressure, and visual disturbances including vision loss have been reported with intravitreal administration. Several instances of blindness have been reported following injection of corticosteroid suspensions into the nasal turbinates and intralesional injection about the head. Care should be taken to avoid ocular exposure to topical and nasal triamcinolone preparations. Visual impairment, ocular hypertension, and worsened cataracts have been reported with ocular exposure to other high potency topical corticosteroids. Preexisting glaucoma may be aggravated if triamcinolone is applied in the periorbital area.
Intramuscular administration of triamcinolone injections is contraindicated in patients with immune thrombocytopenic purpura (ITP).
Indicated vaccination procedures may be undertaken in patients receiving nonimmunosuppressive doses of corticosteroids as replacement therapy (e.g., for Addison's disease). Administration of live or live, attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids. Killed or inactivated vaccines may be administered. However, the response to such vaccines may be diminished and cannot be predicted. The immunosuppressive effects of steroid treatment differ, but many clinicians consider a systemic dose equivalent to either 2 mg/kg/day or 20 mg/day of prednisone as sufficiently immunosuppressive to raise concern about the safety of immunization with live-virus vaccines. In patients who have received high-dose, systemic corticosteroids for 2 weeks or longer, it is recommended to wait at least 3 months after discontinuation of therapy before administering a live-virus vaccine.
Systemic triamcinolone use should be approached with caution during pregnancy and should be used during pregnancy only when the anticipated benefit outweighs the potential fetal risk. Human and animal studies suggest that use of systemic corticosteroids during the first trimester of pregnancy is associated with an increased risk of orofacial clefts, intrauterine growth restriction and decreased birth weight. If systemic triamcinolone must be used chronically during pregnancy, the potential risks should be discussed with the patient. Infants born to women receiving large doses of systemic corticosteroids during pregnancy should be monitored for signs of adrenal insufficiency, and appropriate therapy should be initiated, if necessary. Caution is also recommended with the use of nasal triamcinolone. Topical use of triamcinolone during pregnancy should also be approached with caution. Topical corticosteroids, including triamcinolone, should not be used in large amounts, on large areas, or for prolonged periods of time in pregnant women. Guidelines recommend mild to moderate potency topical agents over potent corticosteroids, which should be used in short durations. Fetal growth restriction and a significantly increased risk of low birthweight has been reported with use of potent or very potent topical corticosteroids during the third trimester, particularly when using more than 300 grams. Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. No studies have been conducted with suprachoroidal injection of triamcinolone acetonide (Xipere) in pregnant patients. It is unknown if this route of administration could be associated with fetal risks; however, systemic exposure following suprachoroidal administration is negligible. Administer during pregnancy only if the potential benefit justifies the potential risk to the infant.
There are no adequate data on the effect of triamcinolone on the breastfed infant, or the effects on milk production during breast-feeding. Corticosteroids are secreted in human milk. Reports suggest that steroid concentrations in human milk are 5 to 25% of maternal serum levels, and that total infant daily doses are small, less than 0.2% of the maternal daily dose. Reviewers and an expert panel consider inhaled, nasal, and oral corticosteroids acceptable to use during breast-feeding. It is not known whether ocular or topical administration of triamcinolone could result in sufficient systemic absorption to produce detectable quantities in breast milk. However, most dermatologists stress that topical corticosteroids can be safely used during lactation and breast-feeding. If applied topically, care should be used to ensure the infant will not come into direct contact with the area of application, such as the breast. Increased blood pressure has been reported in an infant whose mother applied a high potency topical corticosteroid ointment directly to the nipples. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition.
Triamcinolone injection formulas contain the preservative benzyl alcohol and should not be used in neonates, premature neonates, and patients with benzyl alcohol hypersensitivity. Administration of benzyl alcohol to neonates can result in 'gasping syndrome,' which is a potentially fatal condition characterized by metabolic acidosis, and CNS, respiratory, circulatory, and renal dysfunction; it is also characterized by high concentrations of benzyl alcohol and its metabolites in the blood and urine. While the minimum amount of benzyl alcohol at which toxicity may occur is not known, 'gasping syndrome' has been associated with benzyl alcohol dosages greater than 99 mg/kg/day in neonates and low-birth-weight neonates. Additional symptoms may include gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic failure, renal failure, hypotension, bradycardia, and cardiovascular collapse. Rare cases of death, primarily in preterm neonates, have been reported. Further, an increased incidence of kernicterus, especially in small, preterm neonates has been reported. Practitioners administering this and other medications containing benzyl alcohol should consider the combined daily metabolic load of benzyl alcohol from all sources. Premature neonates, neonates with low birth weight, and patients who receive a high dose may be more likely to develop toxicity.
Use systemic corticosteroids such as triamcinolone with caution in the geriatric adult; the risks and benefits of therapy should be considered for any individual patient, particularly with chronic use. According to the Beers Criteria, systemic corticosteroids are considered potentially inappropriate medications (PIMs) for use in geriatric patients with delirium or at high risk for delirium; avoid when possible in these patients due to the possibility of new-onset delirium or exacerbation of the current condition. Oral and parenteral corticosteroids may be required for conditions such as exacerbation of chronic obstructive pulmonary disease (COPD) but should be prescribed in the lowest effective dose and for the shortest possible duration.

Nasal dosage (triamcinolone acetonide nasal spray 55 mcg/spray; e.g., Nasacort Allergy 24HR OTC):
Adults: Initially, 2 sprays into each nostril once daily (total dose of 220 mcg). Dosage should be reduced to the minimum effective dose. Maximum effects usually occur within 1 week of initiation of therapy. If adequate relief of symptoms is not achieved after 3 weeks of treatment, the drug should be discontinued.
Children and Adolescents 12 years and older: Initially, 2 sprays into each nostril once daily (total dose of 220 mcg). Dosage should be reduced to the minimum effective dose. Maximum effects usually occur within 1 week of initiation of therapy. If adequate relief of symptoms is not achieved after 3 weeks of treatment, the drug should be discontinued.

*non-FDA-approved indication
Abatacept: (Moderate) Concomitant use of immunosuppressives, as well as long-term corticosteroids, may potentially increase the risk of serious infection in abatacept treated patients. Advise patients taking abatacept to seek immediate medical advice if they develop signs and symptoms suggestive of infection.
Acarbose: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Acetaminophen; Aspirin, ASA; Caffeine: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
Acetaminophen; Aspirin: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
Acetaminophen; Aspirin; Diphenhydramine: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
Acetaminophen; Chlorpheniramine; Dextromethorphan; Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Acetaminophen; Chlorpheniramine; Phenylephrine : (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Acetaminophen; Dextromethorphan; Guaifenesin; Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Acetaminophen; Dextromethorphan; Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Acetaminophen; Guaifenesin; Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Acetaminophen; Ibuprofen: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Acetaminophen; Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Acetazolamide: (Moderate) Corticosteroids may increase the risk of hypokalemia if used concurrently with acetazolamide. Hypokalemia may be especially severe with prolonged use of corticotropin, ACTH. Monitor serum potassium levels to determine the need for potassium supplementation and/or alteration in drug therapy.
Adagrasib: (Moderate) Monitor for an increase in triamcinolone-related adverse effects, such as fluid retention, electrolyte disturbances, and adrenal suppression, if concomitant use of adagrasib is necessary. Concomitant use may increase triamcinolone exposure. Triamcinolone is a CYP3A substrate and adagrasib is a strong CYP3A inhibitor. Other strong CYP3A inhibitors have decreased corticosteroid metabolism by up to 60%.
Aldesleukin, IL-2: (Major) Avoid coadministration of corticosteroids with aldesleukin. Corticosteroids can be immunosuppressive. Aldesleukin is an interleukin-2 lymphocyte growth factor which induces lymphokine-activated killer (LAK) cells, natural killer (NK) cells, and interferon gamma production. Concomitant use may reduce the efficacy of aldesleukin.
Alemtuzumab: (Moderate) Concomitant use of alemtuzumab with immunosuppressant doses of corticosteroids may increase the risk of immunosuppression. Monitor patients carefully for signs and symptoms of infection.
Aliskiren; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.
Alogliptin: (Moderate) Monitor blood glucose during concomitant corticosteroid and dipeptidyl peptidase-4 (DPP-4) inhibitor use; a DPP-4 dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Alogliptin; Metformin: (Moderate) Monitor blood glucose during concomitant corticosteroid and dipeptidyl peptidase-4 (DPP-4) inhibitor use; a DPP-4 dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells. (Moderate) Monitor blood glucose during concomitant corticosteroid and metformin use; a metformin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Alogliptin; Pioglitazone: (Moderate) Monitor blood glucose during concomitant corticosteroid and dipeptidyl peptidase-4 (DPP-4) inhibitor use; a DPP-4 dose adjustment may be necessary.

Macimorelin: (Major) Avoid use of macimorelin with drugs that directly affect pituitary growth hormone secretion, such as corticosteroids. Healthcare providers are advised to discontinue corticosteroid therapy and observe a sufficient washout period before administering macimorelin. Use of these medications together may impact the accuracy of the macimorelin growth hormone test.
Magnesium Salicylate: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
Mannitol: (Moderate) Corticosteroids may accentuate the electrolyte loss associated with diuretic therapy resulting in hypokalemia. Also, corticotropin may cause calcium loss and sodium and fluid retention. Mannitol itself can cause hypernatremia. Close monitoring of electrolytes should occur in patients receiving these drugs concomitantly.
Measles Virus; Mumps Virus; Rubella Virus; Varicella Virus Vaccine, Live: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Measles/Mumps/Rubella Vaccines, MMR: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Mecasermin, Recombinant, rh-IGF-1: (Moderate) Additional monitoring may be required when coadministering systemic or inhaled corticosteroids and mecasermin, recombinant, rh-IGF-1. In animal studies, corticosteroids impair the growth-stimulating effects of growth hormone (GH) through interference with the physiological stimulation of epiphyseal chondrocyte proliferation exerted by GH and IGF-1. Dexamethasone administration on long bone tissue in vitro resulted in a decrease of local synthesis of IGF-1. Similar counteractive effects are expected in humans. If systemic or inhaled glucocorticoid therapy is required, the steroid dose should be carefully adjusted and growth rate monitored.
Meclofenamate Sodium: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Mefenamic Acid: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Meglitinides: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Meloxicam: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Meningococcal Group B Vaccine (3 strain): (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Meningococcal Group B Vaccine (4 strain): (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Meningococcal Groups A, B, C, W, and Y Vaccine (5 valent): (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Meningococcal Groups A, C, W, and Y Vaccine (4 valent): (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Mercaptopurine, 6-MP: (Minor) Concurrent use of purine analogs with other agents which cause bone marrow or immune suppression such as other antineoplastic agents or immunosuppressives may result in additive effects.
Metformin: (Moderate) Monitor blood glucose during concomitant corticosteroid and metformin use; a metformin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Metformin; Repaglinide: (Moderate) Monitor blood glucose during concomitant corticosteroid and metformin use; a metformin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells. (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Metformin; Saxagliptin: (Moderate) Monitor blood glucose during concomitant corticosteroid and dipeptidyl peptidase-4 (DPP-4) inhibitor use; a DPP-4 dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells. (Moderate) Monitor blood glucose during concomitant corticosteroid and metformin use; a metformin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Metformin; Sitagliptin: (Moderate) Monitor blood glucose during concomitant corticosteroid and dipeptidyl peptidase-4 (DPP-4) inhibitor use; a DPP-4 dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells. (Moderate) Monitor blood glucose during concomitant corticosteroid and metformin use; a metformin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Methazolamide: (Moderate) Corticosteroids may increase the risk of hypokalemia if used concurrently with methazolamide. Hypokalemia may be especially severe with prolonged use of corticotropin, ACTH. Monitor serum potassium levels to determine the need for potassium supplementation and/or alteration in drug therapy. The chronic use of corticosteroids may augment calcium excretion with methazolamide leading to increased risk for hypocalcemia and/or osteoporosis.
Methenamine; Sodium Salicylate: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
Methoxsalen: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
Metolazone: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.
Metoprolol; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.
Metyrapone: (Contraindicated) Medications which affect pituitary or adrenocortical function, including all corticosteroid therapy, should be discontinued prior to and during testing with metyrapone. Patients taking inadvertent doses of corticosteroids on the test day may exhibit abnormally high basal plasma cortisol levels and a decreased response to the test. Although systemic absorption of topical corticosteroids is minimal, temporary discontinuation of these products should be considered if possible to reduce the potential for interference with the test results.
Micafungin: (Moderate) Leukopenia, neutropenia, anemia, and thrombocytopenia have been associated with micafungin. Patients who are taking immunosuppressives such as the corticosteroids with micafungin concomitantly may have additive risks for infection or other side effects. In a pharmacokinetic trial, micafungin had no effect on the pharmacokinetics of prednisolone. Acute intravascular hemolysis and hemoglobinuria was seen in a healthy volunteer during infusion of micafungin (200 mg) and oral prednisolone (20 mg). This reaction was transient, and the subject did not develop significant anemia.
Mifepristone: (Major) Mifepristone for termination of pregnancy is contraindicated in patients on long-term corticosteroid therapy and mifepristone for Cushing's disease or other chronic conditions is contraindicated in patients who require concomitant treatment with systemic corticosteroids for life-saving purposes, such as serious medical conditions or illnesses (e.g., immunosuppression after organ transplantation). For other situations where corticosteroids are used for treating non-life threatening conditions, mifepristone may lead to reduced corticosteroid efficacy and exacerbation or deterioration of such conditions. This is because mifepristone exhibits antiglucocorticoid activity that may antagonize corticosteroid therapy and the stabilization of the underlying corticosteroid-treated illness. Mifepristone may also cause adrenal insufficiency, so patients receiving corticosteroids for non life-threatening illness require close monitoring. Because serum cortisol levels remain elevated and may even increase during treatment with mifepristone, serum cortisol levels do not provide an accurate assessment of hypoadrenalism. Patients should be closely monitored for signs and symptoms of adrenal insufficiency, If adrenal insufficiency occurs, stop mifepristone treatment and administer systemic glucocorticoids without delay; high doses may be needed to treat these events. Factors considered in deciding on the duration of glucocorticoid treatment should include the long half-life of mifepristone (85 hours).
Miglitol: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Mitoxantrone: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
Moxifloxacin: (Moderate) Quinolones have been associated with an increased risk of tendon rupture requiring surgical repair or resulting in prolonged disability; this risk is further increased in those receiving concomitant corticosteroids. Discontinue quinolone therapy at the first sign of tendon inflammation or tendon pain, as these are symptoms that may precede rupture of the tendon.
Nabumetone: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Naproxen: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Naproxen; Esomeprazole: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Naproxen; Pseudoephedrine: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Natalizumab: (Major) Ordinarily, patients receiving chronic immunosuppressant therapy should not be treated with natalizumab. Treatment recommendations for combined corticosteroid therapy are dependent on the underlying indication for natalizumab therapy. Corticosteroids should be tapered in those patients with Crohn's disease who are on chronic corticosteroids when they start natalizumab therapy, as soon as a therapeutic benefit has occurred. If the patient cannot discontinue systemic corticosteroids within 6 months, discontinue natalizumab. The concomitant use of natalizumab and corticosteroids may further increase the risk of serious infections, including progressive multifocal leukoencephalopathy, over the risk observed with use of natalizumab alone. In multiple sclerosis (MS) clinical trials, an increase in infections was seen in patients concurrently receiving short courses of corticosteroids. However, the increase in infections in natalizumab-treated patients who received steroids was similar to the increase in placebo-treated patients who received steroids. Short courses of steroid use during natalizumab, such as when they are needed for MS relapse treatment, appear to be acceptable for use concurrently.
Nateglinide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Nefazodone: (Moderate) Nefazodone may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving another strong CYP3A4 inhibitor with triamcinolone, resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression. Consider the benefit-risk of concomitant use and monitor for systemic corticosteroid side effects. Consider using an alternative treatment to triamcinolone, such as a corticosteroid not metabolized by CYP3A4 (i.e., beclomethasone or prednisolone). In some patients, a corticosteroid dose adjustment may be needed. If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Nelarabine: (Minor) Because systemically administered corticosteroids exhibit immunosuppressive effects when given in high doses and/or for extended periods, additive effects may be seen with other immunosuppressives or antineoplastic agents.
Nelfinavir: (Moderate) Nelfinavir may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving another strong CYP3A4 inhibitor with triamcinolone, resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression. Consider the benefit-risk of concomitant use and monitor for systemic corticosteroid side effects. Consider using an alternative treatment to triamcinolone, such as a corticosteroid not metabolized by CYP3A4 (i.e., beclomethasone or prednisolone). In some patients, a corticosteroid dose adjustment may be needed. If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Neostigmine: (Moderate) Concomitant use of anticholinesterase agents, such as neostigmine, and systemic corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating systemic corticosteroid therapy.
Neostigmine; Glycopyrrolate: (Moderate) Concomitant use of anticholinesterase agents, such as neostigmine, and systemic corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating systemic corticosteroid therapy.
Neuromuscular blockers: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
Nirmatrelvir; Ritonavir: (Moderate) Ritonavir may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving ritonavir (a strong CYP3A4 inhibitor) along with corticosteroids resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression. Consider the benefit-risk of concomitant use and monitor for systemic corticosteroid side effects. Consider using an alternative treatment to triamcinolone, such as a corticosteroid not metabolized by CYP3A4 (i.e., beclomethasone or prednisolone). In some patients, a corticosteroid dose adjustment may be needed. If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Non-Live Vaccines: (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Nonsteroidal antiinflammatory drugs: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Norethindrone Acetate; Ethinyl Estradiol; Ferrous fumarate: (Moderate) Monitor for corticosteroid-related adverse events if corticosteroids are used with estrogens. Concurrent use may increase the exposure of corticosteroids. Estrogens may decrease the hepatic clearance of corticosteroids thereby increasing their effect.

Ocrelizumab: (Moderate) Ocrelizumab has not been studied in combination with other immunosuppressive or immune modulating therapies used for the treatment of multiple sclerosis, including immunosuppressant doses of corticosteroids. Concomitant use of ocrelizumab with any of these therapies may increase the risk of immunosuppression. Monitor patients carefully for signs and symptoms of infection.
Ofatumumab: (Moderate) Concomitant use of ofatumumab with corticosteroids may increase the risk of immunosuppression. Monitor patients carefully for signs and symptoms of infection. Ofatumumab has not been studied in combination with other immunosuppressive or immune modulating therapies used for the treatment of multiple sclerosis, including immunosuppressant doses of corticosteroids.
Ofloxacin: (Moderate) Quinolones have been associated with an increased risk of tendon rupture requiring surgical repair or resulting in prolonged disability; this risk is further increased in those receiving concomitant corticosteroids. Discontinue quinolone therapy at the first sign of tendon inflammation or tendon pain, as these are symptoms that may precede rupture of the tendon.
Olmesartan; Amlodipine; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.
Olmesartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.

Pancuronium: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
Pegaspargase: (Moderate) Monitor for an increase in glucocorticoid-related adverse reactions such as hyperglycemia and osteonecrosis during concomitant use of pegaspargase and glucocorticoids.
Penicillamine: (Major) Agents such as immunosuppressives have adverse reactions similar to those of penicillamine. Concomitant use of penicillamine with these agents is contraindicated because of the increased risk of developing severe hematologic and renal toxicity.
Pentostatin: (Minor) Concurrent use of purine analogs with other agents which cause bone marrow or immune suppression such as other antineoplastic agents or immunosuppressives may result in additive effects.
Phenobarbital: (Moderate) Coadministration may result in decreased exposure to triamcinolone. Phenobarbital is a CYP3A4 inducer; triamcinolone is a CYP3A4 substrate. Monitor for decreased response to triamcinolone during concurrent use.

Phenylephrine: (Moderate) The therapeutic effect of phenylephrine may be increased in patient receiving corticosteroids, such as hydrocortisone. Monitor patients for increased pressor effect if these agents are administered concomitantly.
Phenytoin: (Moderate) Monitor for decreased corticosteroid efficacy if triamcinolone is used with phenytoin; a dosage increase may be necessary. Concurrent use may decrease the exposure of triamcinolone.
Photosensitizing agents (topical): (Minor) Corticosteroids administered prior to or concomitantly with photosensitizing agents used in photodynamic therapy may decrease the efficacy of the treatment.
Physostigmine: (Moderate) Concomitant use of anticholinesterase agents, such as physostigmine, and systemic corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, withdraw anticholinesterase inhibitors at least 24 hours before initiating corticosteroid therapy.
Pimozide: (Moderate) According to the manufacturer of pimozide, the drug should not be coadministered with drugs known to cause electrolyte imbalances, such as high-dose, systemic corticosteroid therapy. Pimozide is associated with a well-established risk of QT prolongation and torsade de pointes (TdP), and electrolyte imbalances (e.g., hypokalemia, hypocalcemia, hypomagnesemia) may increase the risk of life-threatening arrhythmias. Pimozide is contraindicated in patients with known hypokalemia or hypomagnesemia. Topical corticosteroids are less likely to interact.
Pioglitazone: (Moderate) Monitor blood glucose during concomitant corticosteroid and thiazolidinedione use; a thiazolidinedione dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Pioglitazone; Glimepiride: (Moderate) Monitor blood glucose during concomitant corticosteroid and sulfonylurea use; a sulfonylurea dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells. (Moderate) Monitor blood glucose during concomitant corticosteroid and thiazolidinedione use; a thiazolidinedione dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment.

(Moderate) Monitor blood glucose during concomitant corticosteroid and thiazolidinedione use; a thiazolidinedione dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Piroxicam: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and nonsteroidal antiinflammatory drug (NSAID) use. Concomitant use increases the risk of GI bleeding.
Pneumococcal Vaccine, Polyvalent: (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Ponesimod: (Moderate) Monitor for signs and symptoms of infection. Additive immune suppression may result from concomitant use of ponesimod and high-dose corticosteroid therapy which may extend the duration or severity of immune suppression. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days.
Posaconazole: (Moderate) Posaconazole may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving another strong CYP3A4 inhibitor with triamcinolone, resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression. Consider the benefit-risk of concomitant use and monitor for systemic corticosteroid side effects. Consider using an alternative treatment to triamcinolone, such as a corticosteroid not metabolized by CYP3A4 (i.e., beclomethasone or prednisolone). In some patients, a corticosteroid dose adjustment may be needed. If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Potassium-sparing diuretics: (Minor) The manufacturer of spironolactone lists corticosteroids as a potential drug that interacts with spironolactone. Intensified electrolyte depletion, particularly hypokalemia, may occur. However, potassium-sparing diuretics such as spironolactone do not induce hypokalemia. In fact, hypokalemia is one of the indications for potassium-sparing diuretic therapy. Therefore, drugs that induce potassium loss, such as corticosteroids, could counter the hyperkalemic effects of potassium-sparing diuretics.
Pramlintide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Prasterone, Dehydroepiandrosterone, DHEA (Dietary Supplements): (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
Prasterone, Dehydroepiandrosterone, DHEA (FDA-approved): (Moderate) Corticosteroids blunt the adrenal secretion of endogenous DHEA and DHEAS, resulting in reduced DHEA and DHEAS serum concentrations.
Prilocaine; Epinephrine: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and epinephrine use due to risk for additive hypokalemia; potassium supplementation may be necessary. Corticosteroids may potentiate the hypokalemic effects of epinephrine.
Primidone: (Moderate) Coadministration may result in decreased exposure to triamcinolone. Primidone is a CYP3A4 inducer; triamcinolone is a CYP3A4 substrate. Monitor for decreased response to triamcinolone during concurrent use.

Pyridostigmine: (Moderate) Concomitant use of anticholinesterase agents, such as pyridostigmine, and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy.
Quinapril; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.
Quinolones: (Moderate) Quinolones have been associated with an increased risk of tendon rupture requiring surgical repair or resulting in prolonged disability; this risk is further increased in those receiving concomitant corticosteroids. Discontinue quinolone therapy at the first sign of tendon inflammation or tendon pain, as these are symptoms that may precede rupture of the tendon.
Rabies Vaccine: (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Regular Insulin: (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Regular Insulin; Isophane Insulin (NPH): (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment.

Concurrent use may increase the exposure of corticosteroids. Estrogens may decrease the hepatic clearance of corticosteroids thereby increasing their effect.
Repaglinide: (Moderate) Monitor patients receiving antidiabetic agents closely for worsening glycemic control when corticosteroids are instituted and for signs of hypoglycemia when corticosteroids are discontinued. Systemic and inhaled corticosteroids are known to increase blood glucose and worsen glycemic control in patients taking antidiabetic agents. The main risk factors for impaired glucose tolerance due to corticosteroids are the dose of steroid and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.

When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Ritonavir: (Moderate) Ritonavir may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving ritonavir (a strong CYP3A4 inhibitor) along with corticosteroids resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression. Consider the benefit-risk of concomitant use and monitor for systemic corticosteroid side effects. Consider using an alternative treatment to triamcinolone, such as a corticosteroid not metabolized by CYP3A4 (i.e., beclomethasone or prednisolone). In some patients, a corticosteroid dose adjustment may be needed. If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Rituximab: (Moderate) Rituximab and corticosteroids are commonly used together; however, monitor the patient for immunosuppression and signs and symptoms of infection during combined chronic therapy.

Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Rotavirus Vaccine: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Salicylates: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.
Salsalate: (Moderate) Monitor for gastrointestinal toxicity during concurrent corticosteroid and salicylate use. Concomitant use increases the risk of GI bleeding. In patients receiving concomitant corticosteroids and chronic use of salicylates, withdrawal of corticosteroids may result in salicylism because corticosteroids enhance renal clearance of salicylates and their withdrawal is followed by return to normal rates of renal clearance.

If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Sargramostim, GM-CSF: (Major) Avoid the concomitant use of sargramostim and systemic corticosteroid agents due to the risk of additive myeloproliferative effects. If coadministration of these drugs is required, frequently monitor patients for clinical and laboratory signs of excess myeloproliferative effects (e.g., leukocytosis). Sargramostim is a recombinant human granulocyte-macrophage colony-stimulating factor that works by promoting proliferation and differentiation of hematopoietic progenitor cells.

Smallpox and Monkeypox Vaccine, Live, Nonreplicating: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Smallpox Vaccine, Vaccinia Vaccine: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days.

Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Sodium Benzoate; Sodium Phenylacetate: (Moderate) Corticosteroids may cause protein breakdown, which could lead to elevated blood ammonia concentrations, especially in patients with an impaired ability to form urea. Corticosteroids should be used with caution in patients receiving treatment for hyperammonemia.
Sodium Phenylbutyrate: (Moderate) The concurrent use of corticosteroids with sodium phenylbutyrate may increase plasma ammonia levels (hyperammonemia) by causing the breakdown of body protein. Patients with urea cycle disorders being treated with sodium phenylbutyrate usually should not receive regular treatment with corticosteroids.
Sodium Phenylbutyrate; Taurursodiol: (Moderate) The concurrent use of corticosteroids with sodium phenylbutyrate may increase plasma ammonia levels (hyperammonemia) by causing the breakdown of body protein. Patients with urea cycle disorders being treated with sodium phenylbutyrate usually should not receive regular treatment with corticosteroids.
Somapacitan: (Moderate) Patients treated with glucocorticoid replacement for hypoadrenalism may require an increase in their maintenance or stress steroid doses following initiation of somapacitan. Monitor for signs/symptoms of reduced serum cortisol concentrations. Growth hormone (GH) inhibits 11betaHSD-1. Consequently, patients with untreated GH deficiency have relative increases in 11betaHSD-1 and serum cortisol. The initiation of somapacitan may result in inhibition of 11betaHSD-1 and reduced serum cortisol concentrations.
Somatrogon: (Moderate) Monitor for a decrease in serum cortisol concentrations and corticosteroid efficacy during concurrent use of corticosteroids and somatrogon. Patients treated with glucocorticoid replacement for hypoadrenalism may require an increase in their maintenance or stress steroid doses following initiation of somatrogon. Additionally, supraphysiologic glucocorticoid treatment may attenuate the growth promoting effects of somatrogon. Carefully adjust glucocorticoid replacement dosing to avoid hypoadrenalism and an inhibitory effect on growth.
Somatropin, rh-GH: (Moderate) Corticosteroids can retard bone growth and therefore, can inhibit the growth-promoting effects of somatropin. If corticosteroid therapy is required, the corticosteroid dose should be carefully adjusted.
Sotagliflozin: (Moderate) Monitor blood glucose during concomitant corticosteroid and SGLT2 inhibitor use; a SGLT2 inhibitor dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Spironolactone: (Minor) The manufacturer of spironolactone lists corticosteroids as a potential drug that interacts with spironolactone. Intensified electrolyte depletion, particularly hypokalemia, may occur. However, potassium-sparing diuretics such as spironolactone do not induce hypokalemia. In fact, hypokalemia is one of the indications for potassium-sparing diuretic therapy. Therefore, drugs that induce potassium loss, such as corticosteroids, could counter the hyperkalemic effects of potassium-sparing diuretics.
Spironolactone; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary.

Tick-Borne Encephalitis Vaccine: (Moderate) Patients receiving high-dose corticosteroid therapy may have a diminished response to vaccines. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 2 weeks after discontinuation. If vaccine administration is necessary, consider revaccination following restoration of immune competence. Counsel patients receiving high-dose corticosteroids about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure after receiving the vaccine.
Tipranavir: (Moderate) Tipranavir may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations.

Therefore, drugs that induce potassium loss, such as corticosteroids, could counter the hyperkalemic effects of potassium-sparing diuretics.
Tuberculin Purified Protein Derivative, PPD: (Moderate) Immunosuppressives may decrease the immunological response to tuberculin purified protein derivative, PPD. This suppressed reactivity can persist for up to 6 weeks after treatment discontinuation. Consider deferring the skin test until completion of the immunosuppressive therapy.
Tucatinib: (Moderate) Tucatinib may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving another strong CYP3A4 inhibitor with triamcinolone, resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression.

Typhoid Vaccine: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Urea: (Moderate) The potassium-wasting effects of corticosteroid therapy can be exacerbated by concomitant administration of other potassium-depleting drugs such as diuretics. Serum potassium levels should be monitored in patients receiving these drugs concomitantly.
Valsartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor potassium concentrations during concomitant corticosteroid and thiazide diuretic use due to risk for additive hypokalemia; potassium supplementation may be necessary. Both corticosteroids and thiazide diuretics cause increased renal potassium loss.

Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Vecuronium: (Moderate) Limit the period of use of neuromuscular blockers and corticosteroids and only use when the specific advantages of the drugs outweigh the risks for acute myopathy. An acute myopathy has been observed with the use of high doses of corticosteroids in patients receiving concomitant long-term therapy with neuromuscular blockers. Clinical improvement or recovery after stopping therapy may require weeks to years.
Vigabatrin: (Major) Vigabatrin should not be used with corticosteroids, which are associated with serious ophthalmic effects (e.g., retinopathy or glaucoma) unless the benefit of treatment clearly outweighs the risks.
Vonoprazan; Amoxicillin; Clarithromycin: (Moderate) Clarithromycin may inhibit the CYP3A4 metabolism of triamcinolone, resulting in increased plasma triamcinolone concentrations and reduced serum cortisol concentrations. There have been reports of clinically significant drug interactions in patients receiving another strong CYP3A4 inhibitor with triamcinolone, resulting in systemic corticosteroid effects including, but not limited to, Cushing syndrome and adrenal suppression.

If corticosteroid therapy is to be discontinued, consider tapering the dose over a period of time to decrease the potential for withdrawal.
Voriconazole: (Moderate) Monitor for potential adrenal dysfunction with concomitant use of voriconazole and triamcinolone. In patients taking corticosteroids, voriconazole-associated CYP3A4 inhibition of their metabolism may lead to corticosteroid excess and adrenal suppression. Corticosteroid exposure is likely to be increased. Voriconazole is a strong CYP3A4 inhibitor, and triamcinolone is a CYP3A4 substrate.
Vorinostat: (Moderate) Use vorinostat and corticosteroids together with caution; the risk of QT prolongation and arrhythmias may be increased if electrolyte abnormalities occur. Corticosteroids may cause electrolyte imbalances; hypomagnesemia, hypokalemia, or hypocalcemia and may increase the risk of QT prolongation with vorinostat. Frequently monitor serum electrolytes if concomitant use of these drugs is necessary.
Warfarin: (Moderate) Monitor the INR if warfarin is administered with corticosteroids. The effect of corticosteroids on warfarin is variable. There are reports of enhanced as well as diminished effects of anticoagulants when given concurrently with corticosteroids; however, limited published data exist, and the mechanism of the interaction is not well described. High-dose corticosteroids appear to pose a greater risk for increased anticoagulant effect. In addition, corticosteroids have been associated with a risk of peptic ulcer and gastrointestinal bleeding.
Yellow Fever Vaccine, Live: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Zafirlukast: (Minor) Zafirlukast inhibits the CYP3A4 isoenzymes and should be used cautiously in patients stabilized on drugs metabolized by CYP3A4, such as corticosteroids.
Glucocorticoids prevent or suppress inflammation and immune responses when administered at pharmacological doses. At the molecular level, unbound glucocorticoids readily cross cell membranes and bind with high affinity to specific cytoplasmic receptors. This binding induces a response by modifying transcription and, ultimately, protein synthesis to achieve the steroid's intended action. Such actions can include: inhibition of leukocyte infiltration at the site of inflammation, interference in the function of mediators of inflammatory response, and suppression of humoral immune responses. Some of the net effects include reduction in edema or scar tissue and a general suppression in immune response. The anti-inflammatory actions of corticosteroids are thought to involve phospholipase A2 inhibitory proteins, collectively called lipocortins. Lipocortins, in turn, control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of the precursor molecule arachidonic acid. The degree of clinical effect and the numerous adverse effects related to corticosteroid use usually depend on the dose administered and the duration of therapy.
Early anti-inflammatory effects of topical corticosteroids include the inhibition of macrophage and leukocyte movement and activity in the inflamed area by reversing vascular dilation and permeability. Later inflammatory processes such as capillary production, collagen deposition, and keloid (scar) formation also are inhibited by corticosteroids. Clinically, these actions correspond to decreased edema, erythema, pruritus, plaque formation, and scaling of the affected skin.
In the treatment of allergies, intranasal triamcinolone inhibits the activity of several cell types (e.g., mast cells and eosinophils) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in the allergic response. Clinically, symptoms such as rhinorrhea and postnasal drip, nasal congestion, sneezing, and pharyngeal itching are reduced.
Although the exact mechanisms for the anti-edematous, anti-inflammatory, and antiangiogenic actions of triamcinolone in the treatment of macular edema are unclear, a proposed mechanism of action is that ocular injection of triamcinolone increases the levels of right-junction proteins, thereby diminishing vessel leakage and angiostatic actions through vascular endothelial growth factor (VEGF) inhibition and down regulation.
Triamcinolone is administered topically, nasally, or by intramuscular, intra-articular, intravitreal, and suprachoroidal injection. It has also been administered by orally and by respiratory inhalation, although these dosage forms are no longer marketed. The onset and duration of action of triamcinolone injection suspensions depend on the route of administration and the extent of the local blood supply. The circulating drug binds weakly to plasma proteins, and only the unbound portion of the drug is active. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys; some corticosteroids and their metabolites are also excreted into the bile. Systemic triamcinolone is quickly distributed into the kidneys, intestines, skin, liver, and muscle. Corticosteroids distribute into breast milk and cross the placenta. Any systemically absorbed triamcinolone is metabolized by the liver; 3 metabolites have been identified that have little to no activity compared to the parent compound. Approximately 40% of the administered dose is excreted in the urine, and 60% in the feces, primarily as the metabolites. The plasma half-life of triamcinolone is approximately 88 minutes following an intravenous dose. However, the plasma half-life of the corticosteroids does not correlate well with the biologic half-life of the drugs. Some triamcinolone formulas, like the injection suspension, have prolonged durations of action which may be sustained over a period of several weeks (e.g., 30 to 40 days). The extended-release suspension injection has an even longer duration of action when given into a joint.

-Route-Specific Pharmacokinetics
Oral Route
Oral mucosal application
The extent of absorption through the oral mucosa is determined by multiple factors including the vehicle, the integrity of the mucosal barrier, the duration of therapy, and the presence of inflammation and/or other disease processes. Once absorbed through the mucous membranes, the disposition of corticosteroids is similar to that of systemically administered corticosteroids.
Intramuscular Route
Studies indicate that following a single IM dose of 60 mg to 100 mg of triamcinolone acetonide injection suspension, adrenal suppression occurs within 24 to 48 hours and then gradually returns to normal, usually in 30 to 40 days. The metabolism and excretion of any systemically absorbed drug occurs similar to that of intravenously administered drug.
Topical Route
Bioavailability following topical application of triamcinolone is dependent on the condition of the skin at the application site. The extent of absorption through the skin is determined by multiple factors including the vehicle, the integrity of the skin barrier, the duration of therapy, and the presence of inflammation and/or other disease processes. Absorption of topical preparations is increased in areas of skin damage, inflammation, or occlusion, or where the stratum corneum is thin such as the eyelids, genitalia, and face. Topical preparations are generally metabolized in the skin, but a small amount may be absorbed systemically.
Inhalation Route
Nasal Inhalation
When administered intranasally as a 440 mcg/day dose, the peak plasma concentration was less than 1 ng/mL and occurred on average at 3.4 hours (range 0.5 to 8 hours) post-dosing. The apparent half-life was 4 hours (range 1 to 7 hours); however, this value probably reflects lingering absorption. Intranasal doses below 440 mcg/day did not allow for the calculation of meaningful pharmacokinetic parameters.
Other Route(s)
Intravitreal Route
Following a single intravitreal administration (4 mg) of triamcinolone acetonide, aqueous humor samples were obtained from 1 eye in each of 5 patients via an anterior chamber paracentesis; samples were collected on days 1, 3, 10, 17, and 31 post injection. Peak aqueous humor concentrations ranged from 2,151 to 7,202 ng/mL, the half-life range was 76 to 635 hours, and the AUC from 231 to 1,911 ng x hour/mL. The mean elimination half-life was 18.7 +/- 5.7 days in 4 nonvitrectomized eyes (4 patients) and 3.2 days in a patient who had undergone vitrectomy (1 eye), suggesting the half-life is much faster in a vitrectomized eye vs. a nonvitrectomized eye.
Suprachoroidal Route
Animal data show that suprachoroidal administration of triamcinolone acetonide results in greater amounts of drug in the sclera, choroid, retinal pigment epithelial, and retina than with intravitreal injections. However, lower amounts of drug are found in the anterior segment and lens as compared to intravitreal injections. In humans, plasma drug concentrations were evaluated in 19 patients who received 4 mg triamcinolone acetonide suprachoroidal injections on Day 0 and Week 12. Drug concentrations in all 19 patients were below 100 pg/mL at Weeks 4, 12, and 24, except for 1 patient whose value was 243.4 pg/mL prior to the second dose at Week 12. Concentrations ranged from less than 10 pg/mL (lower limits of the assay) to 88.9 pg/mL.
Intra-articular Route
Intra-articularly injected corticosteroids may be systemically absorbed. Among 33 patients, the mean (SD) half-life of triamcinolone acetonide extended-release suspension was 633.9 (893) hours, compared to 146.9 (213.29) hours among 14 patients who received immediate-release triamcinolone acetonide.
-Special Populations
Hepatic Impairment
Triamcinolone is extensively metaobolized in the liver. Hepatic impairment may reduce the metabolism of systemically absorbed drug, possibly increasing glucocorticoid effects. There is an enhanced effect of corticosteroids in patients with severe hepatic impairment (cirrhosis).
