Canagliflozin is an oral sodium-glucose co-transporter 2 (SGLT2) inhibitor. Canagliflozin works by blocking the reabsorption of glucose by the kidney, which results in increased urinary glucose excretion and reduced blood glucose concentrations. Canagliflozin is used to improve glycemic control in adults with type 2 diabetes mellitus (T2DM) and to reduce the risk of major adverse cardiovascular (CV) events (MACE) in type 2 DM patients who also have CV disease. Canagliflozin is also used to reduce the risk of end-stage kidney disease (ESKD), doubling of serum creatinine, CV death, and hospitalization for heart failure (HF) in adults with T2DM and diabetic nephropathy with albuminuria greater than 300 mg/day. Mean A1C reductions of 0.77% to 1.03% are achieved with use. Canagliflozin has been shown to reduce CV risk and HF risk in clinical trials. Canagliflozin significantly reduced the risk of major adverse CV events (major cardiovascular events (MACE): CV death, the first occurrence of non-fatal myocardial infarction, or non-fatal stroke) by 14% relative to placebo (HR 0.86, 95% CI 0.75 to 0.97) in patients with T2DM and established, stable, atherosclerotic cardiovascular disease (ASCVD). In the CREDENCE trial, the risk of the primary composite outcome of ESKD, doubling of serum creatinine, or death from renal or CV causes was 30% lower with canagliflozin treatment when compared with placebo. Patients with renal impairment using canagliflozin for glycemic control may be more likely to experience hypotension and may be at a higher risk for kidney injury. Canagliflozin has been associated with increased risk of lower-limb amputations, most frequently of the toe and midfoot, but some also involved the leg. Some patients had multiple amputations, some involving both lower limbs. First-line T2DM therapy depends on comorbidities, patient-centered treatment factors, and management needs. In adults with T2DM and HF and/or chronic kidney disease (CKD) (with confirmed eGFR of 20 to 60 mL/minute per 1.73 m2 and/or albuminuria), an SGLT2 inhibitor should be initiated as first-line therapy in order to minimize the progression of CKD, reduce CV events, and reduce hospitalizations for HF; however, the glycemic benefits of SGLT2 inhibitors are reduced at eGFR less than 45 mL/minute per 1.73 m2. SGLT2 inhibitors have been shown to significantly reduce the risk of hospitalization for HF or CV death in persons with T2D with or without ASCVD and to improve HF-related symptoms in persons with established HF regardless of LV ejection fraction, background glucose-lowering therapies, or HF therapies. An SGLT2 inhibitor with proven CV benefit (e.g., canagliflozin, empagliflozin) may be used as an alternative to glucagon-like peptide-1 agonist (GLP-1 RA) to reduce the risk of MACE or CV death in persons with T2D and established ASCVD. In patients with T2DM who do not have ASCVD/indicators of high-risk, HF, or CKD and who need to minimize hypoglycemia and/or promote weight loss, SGLT2 inhibitors are generally recommended as a second or third-line option as add-on to metformin therapy as they have a high efficacy for glucose lowering and an intermediate efficacy for weight loss. Canagliflozin was initially FDA approved in 2013.

In glycemic control trials, hypoglycemia occurred in 3.6% of patients receiving monotherapy with canagliflozin 100 mg/day, 3% of patients receiving monotherapy with canagliflozin 300 mg/day, and 2.6% of patients receiving placebo during clinical trials. In all clinical trials, hypoglycemia was defined as any event regardless of symptoms, where any blood glucose value 70 mg/dL or less was documented. Canagliflozin can increase the risk of hypoglycemia when combined with insulin or an insulin secretagogue. In individual clinical trials, episodes of hypoglycemia occurred at a higher rate when canagliflozin was co-administered with insulin or sulfonylureas. A lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with canagliflozin. Symptoms often associated with hyperglycemia have also been reported. In a pooled analysis of 4 placebo-controlled studies of patients treated with canagliflozin, thirst, xerostomia, and polydipsia were reported in 2.8 % of 833 patients receiving canagliflozin 100 mg/day, 2.4% of 834 patients receiving canagliflozin 300 mg/day, and 0.1% of 646 patients receiving placebo.

Canagliflozin results in an osmotic diuresis, which may lead to reductions in intravascular volume. In clinical studies for glycemic control, treatment with canagliflozin was associated with a dose-dependent increase in the incidence of volume depletion related adverse reactions (e.g., hypotension, postural dizziness, orthostatic hypotension, syncope, and dehydration). An increased incidence was observed in patients on the canagliflozin 300 mg/day PO dose. In an adverse reactions study of 2,201 patients participating in the CREDENCE trial, the incidence of hypotension was 2.8% and 1.5% on canaglifozin 100 mg and placebo, respectively. The 3 factors associated with the largest increase in volume depletion-related adverse reactions were the use of loop diuretics, moderate renal impairment (eGFR 30 to 59 mL/minute/1.73 m2), and the elderly who are 75 or more years of age. Volume status should be assessed and corrected before initiating canagliflozin in patients with one or more of these characteristics. Monitor for signs and symptoms after initiating therapy.

Renal-related adverse reactions can occur after initiating canagliflozin, particularly in patients with moderate renal impairment, defined as an estimated glomerular filtration rate (eGFR) less than 45 mL/minute/1.73 m2. Reports include increases in serum creatinine, decreases in eGFR, and renal impairment and acute renal failure (unspecified). In trials for glycemic control, the incidence of renal-related adverse reactions in patients with moderate renal impairment was 3.7% with placebo, 8.9% with canagliflozin 100 mg/day, and 9.3% with canagliflozin 300 mg/day. Discontinuations due to renal-related adverse events occurred in 1% with placebo, 1.2% with canagliflozin 100 mg/day, and 1.6% with canagliflozin 300 mg/day. Patients with hypovolemia or the elderly may be more susceptible to these changes. In patients with moderate renal impairment, the increase in serum creatinine generally does not exceed 0.2 mg/dL, occurs within the first 6 weeks of starting therapy, and then stabilizes. Increases that do not fit this pattern should prompt further evaluation to exclude the possibility of acute kidney injury. Acute kidney injury, in some cases requiring hospitalization and dialysis, has been reported during the postmarketing period. These patients were being treated for glycemic control. In approximately half of the reported cases, acute kidney injury occurred within 1 month of starting the drug. The effect on eGFR reversed after treatment discontinuation, suggesting acute hemodynamic changes may play a role in the renal function changes observed. If acute kidney injury occurs, promptly discontinue the canagliflozin and treat the renal impairment. According to guidelines, randomized clinical outcome trials of advanced kidney disease or high cardiovascular disease risk with normal kidney function have not shown that SGLT2 inhibitors promote acute kidney injury. Despite these findings, the manufacturer recommends that before initiating canagliflozin, consider factors that may predispose patients to acute kidney injury prior to starting them on canagliflozin, including hypovolemia; chronic renal insufficiency; congestive heart failure; and concomitant medications such as diuretics, angiotensin converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs),and nonsteroidal anti-inflammatory drugs (NSAIDs). Consider temporarily discontinuing canagliflozin in any setting of reduced oral intake such as acute illness or fasting, or with fluid losses such as gastrointestinal illness or excessive heat exposure. Assess renal function in all patients prior to initiation of canagliflozin therapy and as clinically indicated.

In patients with moderate renal impairment, increases in potassium and hyperkalemia during canagliflozin treatment were more commonly seen in those with elevated potassium at baseline and in those using medications that reduce potassium excretion, such as potassium-sparing diuretics, angiotensin-converting-enzyme inhibitors, and angiotensin-receptor blockers. Monitor serum potassium levels periodically after initiating canagliflozin; metformin in patients with impaired renal function or in those predisposed to hyperkalemia due to medications or other medical conditions. In a pooled population of patients (n = 723) with moderate renal impairment (eGFR 45 to 59 mL/minute/1.73 m2) treated with canagliflozin for glycemic control, increases in serum potassium to greater than 5.4 mEq/L and 15% above baseline occurred in 5.3%, 5%, and 8.8% of patients treated with placebo, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. Severe elevations (6.5 mEq/L or more) occurred in 0.4% of patients taking placebo, 0% of those taking canagliflozin 100 mg, and 1.3% with canagliflozin 300 mg. It should be noted that in the CREDENCE trial, no difference in serum potassium, no increase in adverse events of hyperkalemia, and no increase in absolute (more than 6.5 mEq/L) or relative (greater than upper limit of normal and more than 15% increase from baseline) increases in serum potassium were observed with canagliflozin 100 mg relative to placebo.

Sodium-glucose co-transporter 2 (SGLT2) inhibitors are associated with an increased risk of serious urinary tract infection (UTI), including urosepsis and pyelonephritis. In patients receiving canagliflozin for glycemic control, 19 cases reported to the FDA resulted in hospitalization; however, no deaths were reported. Four patients required admission to the intensive care unit, and two patients required hemodialysis to treat renal failure. The median time to onset was 45 days (range 2 to 270 days). Discontinuation of the SGLT2 inhibitor was reported in 15 cases. Details regarding whether or not there was a prior history of UTI was not available for most of the cases. Blood culture results indicated that E. coli was the isolated organism in 8 of the 19 reports; 11 cases contained no information about blood culture testing. There were no reports of fungal urosepsis. Details regarding the administered antibiotic agent, the course of antibiotic treatment, and evidence of relapse or recurrent infection were not provided in any of the cases. In clinical studies for glycemic control, female genital mycotic infections, urinary tract infection, and increased urinary frequency were the most common adverse reactions in patients taking canagliflozin. Patients with a history of genital mycotic infections were more likely to develop genital mycotic infections. In a pool of 4 placebo-controlled studies, female genital mycotic infections, including vulvovaginal candidiasis, vulvovaginal mycotic infection, vaginitis (reported as vulvovaginitis), vaginal infection, vulvitis, and genital fungal infection, were reported in 10.6% of 425 female patients receiving canagliflozin 100 mg/day, 11.6% of 430 female patients receiving canagliflozin 300 mg/day, and 2.8% of 312 female patients receiving placebo. Female patients who developed genital mycotic infections while receiving canagliflozin were more likely to experience recurrence and require treatment with oral or topical antifungal agents and antimicrobial agents. Vulvovaginal pruritus was reported in 1.6% of 425 female patients receiving canagliflozin 100 mg/day, 3.2% of 430 female patients receiving canagliflozin 300 mg/day, and 0% of female patients receiving placebo. Male genital mycotic infections occurred more commonly in uncircumcised males and in males with a prior history of balanitis or balanoposthitis. In a pool of 4 placebo-controlled studies, male genital mycotic infections, with resultant penile inflammation (balanitis, balanoposthitis), balanitis candida, and genital fungal infection, were reported in 4.2% of 408 male patients receiving canagliflozin 100 mg/day, 3.8% of 404 male patients receiving canagliflozin 300 mg/day, and 0.7% of 334 male patients receiving placebo. Male patients who developed genital mycotic infections on canagliflozin were more likely to experience recurrent infections (22% on canagliflozin vs. 0% placebo), and more likely to require treatment with oral or topical antifungal agents and anti-microbial agents than patients on comparators. In a pooled analysis of 8 randomized trials evaluating glycemic control, phimosis was reported in 0.3% of uncircumcised male patients treated with canagliflozin and 0.2% required circumcision to treat the phimosis. Urinary tract infection, cystitis, kidney infection, and urosepsis were reported in 5.9 % of 833 patients receiving canagliflozin 100 mg/day, 4.4% of 834 patients receiving canagliflozin 300 mg/day vs. 3.8% with placebo. Increased urinary frequency, including polyuria, pollakiuria, urine output increased, urinary urgency, and nocturia was reported in 5.1 % of 833 patients receiving canagliflozin 100 mg, 4.6% of 834 patients receiving canagliflozin 300 mg, and 0.7% of 646 patients receiving placebo. In the clinical evaluation of canagliflozin, 0% of either female or male patients discontinued use of study medication due to genital mycotic infections. Use canagliflozin cautiously in patients with a history of genital fungal infection, including vaginitis or balanitis, and in uncircumcised males. Patients should be told to report any signs or symptoms of such genitourinary infections and seek medical attention if they experience symptoms such as a feeling of burning when urinating or the need to urinate often or right away, pain in the lower part of the stomach area or pelvis, fever, or blood in the urine. Monitor and treat promptly if indicated.

Hypersensitivity and dermatologic reactions, some serious, have been reported in patients treated with canagliflozin; these reactions generally occurred within hours to days after initiating the drug. Anaphylaxis and angioedema have been reported with post-market use. During clinical trials for glycemic control, 5 patients experienced serious adverse reactions of hypersensitivity, which included 4 patients with urticaria and 1 patient with a diffuse rash (unspecified) and urticaria occurring within hours of exposure to canagliflozin. Among these patients, 2 patients discontinued canagliflozin. One patient with urticaria had recurrence when the drug was re-initiated. Erythema, rash, pruritus, urticaria, and angioedema occurred in 3%, 3.8%, and 4.2% of patients receiving comparator, canagliflozin 100 mg/day and canagliflozin 300 mg/day, respectively. Photosensitivity-related adverse reactions (including photosensitivity reaction, polymorphic light eruption, and sunburn) occurred in 0.1%, 0.2%, and 0.2% of patients receiving comparator, canagliflozin 100 mg/day, and canagliflozin 300 mg/day, respectively. Discontinue use of canagliflozin if hypersensitivity reactions occur, and treat per standard of care; monitor until signs and symptoms resolve.

Hyperlipidemia, specifically dose-related increases in LDL-cholesterol (LDL-C), can occur with canagliflozin. In the pool of 4 glycemic control placebo-controlled trials, mean changes (percent changes) from baseline in LDL-C relative to placebo were 4.4 mg/dL (4.5%) and 8.2 mg/dL (8%) with canagliflozin 100 mg and canagliflozin 300 mg, respectively. Dose-related increases in non-HDL-C with canagliflozin were also observed. Mean changes (percent changes) from baseline in non-HDL-C relative to placebo were 2.1 mg/dL (1.5%) and 5.1 mg/dL (3.6%) with canagliflozin 100 mg and 300 mg, respectively. Monitor LDL-C and treat hypercholesterolemia per existing standards of care after initiating canagliflozin therapy.

Gastrointestinal adverse reactions have been reported in patients receiving canagliflozin. In the pool of 4 glycemic control placebo-controlled trials, constipation was reported in 1.8% of 833 patients receiving canagliflozin 100 mg/day, 2.4% of 834 patients receiving canagliflozin 300 mg/day, and 0.9% of 646 patients receiving placebo. Nausea was reported in 2.1% of 833 patients receiving canagliflozin 100 mg/day, 2.3% of 834 patients receiving canagliflozin 300 mg/day, and 1.6% of 646 patients receiving placebo. Abdominal pain was also more commonly reported in patients taking canagliflozin at doses of 100 mg/day (1.8%) or 300 mg/day (1.7%) than in patients taking placebo (0.8%).

In the pooled analysis of 8 clinical trials, fatigue (1.8% with comparator, 2.2% with canagliflozin 100 mg/day, and 2% with canagliflozin 300 mg/day) and asthenia (0.6% with comparator, 0.7% with canagliflozin 100 mg/day and 1.1% with canagliflozin 300 mg/day) were reported in patients receiving canagliflozin for glycemic control.

In the glycemic control trials, pancreatitis (acute or chronic) was reported with an incidence rate of 0.1, 0.2, and 0.1 in patients receiving comparator, canagliflozin 100 mg/day, and canagliflozin 300 mg/day, respectively.

In the CANVAS trial, bone fractures were reported with an incidence rate of 1.09, 1.59, and 1.79 per 100 patient-years of follow-up for the placebo, canagliflozin 100 mg/day, and canagliflozin 300 mg/day groups, respectively. Fractures occurred within the first 26 weeks of therapy and remained through the end of the trial. Fractures were more likely to be low trauma (e.g., fall from not more than standing height) and affect the distal portion of upper and lower extremities. Falls occurred in 1.3%, 1.5%, and 2.1% of patients receiving comparator, canagliflozin 100 mg/day, and canagliflozin 300 mg/day, respectively. The increased risk of falls was observed in patients receiving canagliflozin in the first few weeks of treatment. There may be a risk for osteopenia. In a clinical trial of 714 older patients (age 55 to 80 years), placebo-corrected declines in bone mineral density at the total hip and lumbar spine of 0.9% to 1.2%, and 0.3% to 0.7%, respectively, occurred in patients receiving canagliflozin for 2 years. Bone mineral density declines of 0.1% and 0.4% also occurred at the femoral neck and distal forearm, respectively. Consider factors that contribute to fracture risk before initiating canagliflozin therapy. Advise patients to discuss any risk factors for bone fractures with their healthcare professional but not to discontinue or change their diabetes medications without first talking to their healthcare professional.

Canagliflozin and other sodium-glucose co-transporter 2 (SGLT2) inhibitors have been associated with a serious, rare, life-threatening infection called necrotizing fasciitis (tissue necrosis) of the perineum, also referred to as Fournier's gangrene. In August 2018, the FDA announced that over 5 years, 12 cases of Fournier's gangrene have been identified in patients taking a SGLT2 inhibitor; these cases were identified in the medical literature, and there may be additional unreported cases. Although most cases of Fournier's gangrene have previously been reported in men, the 12 cases included 7 men and 5 women aged 38 to 78 years. The average time to onset of Fournier's gangrene after drug initiation was 9.2 months (range 7 days to 25 months). All 12 patients required surgical debridement, 5 of which required more than 1 surgery and 1 required skin grafting. The clinical course for 4 patients was complicated by diabetic ketoacidosis, acute kidney injury, and septic shock, prolonging their hospitalizations or leading to death. Two patients were transferred to a rehabilitation hospital. The SGLT2 inhibitor was discontinued in 8 cases; 1 patient died, and information on drug continuation or discontinuation was not included in 3 cases. Because diabetes is a known risk factor for Fournier's gangrene, the FDA also examined several other classes of antidiabetic agents to help assess whether the cases of Fournier's gangrene with the SGLT2 inhibitors are more likely to be associated with the underlying condition of diabetes as opposed to the drug. Only 6 cases of Fournier's gangrene (all in men) were identified in the review of other antidiabetic drug classes over a period of more than 30 years. Counsel patients to promptly seek medical attention if they experience any symptoms of tenderness, erythema, or swelling in the genital or perineal area, fever, or malaise. If Fournier's gangrene is suspected, discontinue canagliflozin and institute prompt treatment with antibiotics and surgical debridement, if appropriate. Closely monitor blood glucose levels, and provide appropriate alternative therapy for glycemic control.

Canagliflozin is associated with an increase in the risk of lower limb amputation. Results from the CANVAS and CANVAS-R studies have shown an increase in leg and foot amputations with canagliflozin in patients who had either established cardiovascular disease or who are were at risk for cardiovascular disease. Amputations were mostly involving the toe and midfoot (99 out of 140 patients in both trials); amputations involving the leg, below and above the knee, were also observed (41 out of 140 patients in both trials). The risk of lower limb amputations over one year's time in the CANVAS study was 5.9 amputations per 1,000 patients treated with canagliflozin compared to 2.8 amputations per 1,000 patients treated with placebo. In the CANVAS-R study, the risk of lower limb amputations over one year's time was 7.5 amputations per 1,000 patients for canagliflozin compared to 4.2 amputations per 1,000 patients for placebo. The risk of lower limb amputations was observed at both the 100 mg and 300 mg doses. Some patients had more than 1 amputation, some involving both limbs. Lower limb infections, gangrene (tissue necrosis), diabetic foot ulcers, and ischemia were the most common precipitating medical events leading to an amputation. In the CREDENCE trial, the rate of lower limb amputations associated with the use of canagliflozin 100 mg relative to placebo was 12.3 vs. 11.2 events per 1,000 patient-years, respectively. The risk of amputation was highest in patients with a baseline history of prior amputation, peripheral vascular disease, and neuropathy; therefore, before initiating therapy with canagliflozin, consider risk factors that may predispose patients to the need for amputations. Also, consider the patient's history of diabetic foot ulcers. Monitor patients for infection (osteomyelitis) of the legs and feet and instruct patients to notify their healthcare professional immediately if they notice any new pain or tenderness, unusual sensations, skin color changes, sores or ulcers, or infection in their legs or feet. The patient should self-examine their feet daily in routine diabetes care, and a healthcare professional should routinely perform a complete foot exam.

Reports of ketoacidosis, a serious, life-threatening condition requiring urgent hospitalization have been identified in clinical trials and postmarketing surveillance in patients with type 1 and type 2 diabetes mellitus receiving sodium glucose co-transporter-2 (SGLT2) inhibitors, including canagliflozin. Fatal cases of ketoacidosis have been reported in patients taking canagliflozin. The risk of ketoacidosis may be greater with higher doses. Canagliflozin significantly increases the risk of diabetic ketoacidosis in patients with type 1 diabetes mellitus. In many of the postmarketing reports, and particularly in patients with type 1 diabetes, the presence of ketoacidosis was not immediately recognized, and the institution of treatment was delayed because presenting blood glucose levels were below those typically expected for DKA (often less than 250 mg/dL). Signs and symptoms at presentation were consistent with dehydration and severe metabolic acidosis and included nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. In some but not all cases, factors predisposing to ketoacidosis such as acute febrile illness, infection, reduced caloric intake, ketogenic diet, surgery, reduction in dose of exogenous insulin or discontinuation of exogenous insulin or insulin secretagogue, volume depletion, or alcohol abuse were identified. In the CREDENCE trial, incidence rates of adjudicated events of diabetic ketoacidosis (DKA) were 0.21 (0.5%, 12/2,200) and 0.03 (0.1%, 2/2,197) per 100 patient-years of follow-up with canagliflozin 100 mg and placebo, respectively. Before initiating canagliflozin, consider factors in the patient history that may predispose to ketoacidosis including pancreatic insulin deficiency, caloric restriction, volume depletion, and alcohol abuse. Risk factors for ketoacidosis also include patients with type 2 diabetes mellitus and pancreatic disorders such as, a history of pancreatitis, pancreatic insufficiency, or pancreatic surgery. Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 3 days after discontinuing canagliflozin; however there have been postmarketing reports of ketoacidosis and glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors. Based on the clinical situation, consider ketone monitoring in persons with type 1 diabetes mellitus and in others at risk for ketoacidosis. Patients treated with canagliflozin who present with signs and symptoms consistent with dehydration and severe metabolic acidosis should be assessed for ketoacidosis regardless of presenting blood glucose levels, as ketoacidosis may be present even if blood glucose levels are less than 250 mg/dL. If ketoacidosis is suspected, discontinue canagliflozin, evaluate the patient, and institute prompt treatment. Treatment of ketoacidosis may require insulin, fluid and carbohydrate replacement. Monitor patients for resolution of ketoacidosis before restarting canagliflozin. Withhold canagliflozin, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. For patients who undergo scheduled surgery, canagliflozin should be temporarily discontinued at least 3 days before surgery. Resume canagliflozin when the patient is clinically stable and has resumed oral intake. Educate patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue this product and seek medical attention immediately if signs and symptoms occur.

Canagliflozin may increase the risk for new primary malignancy, specifically renal cell cancer. In the CANVAS trial (mean duration of follow-up of 5.7 years), the incidence of renal cell carcinoma was 0.15% (2/1,331) and 0.29% (8/2,716) for placebo and canagliflozin, respectively. Patients with less than 6 months of follow-up, less than 90 days of treatment, or a history of renal cell carcinoma were excluded. Due to the limited number of cases, a causal relationship to canagliflozin could not be established.

Do not use canagliflozin in patients with a known history of a serious canagliflozin hypersensitivity reaction. Hypersensitivity reactions, including anaphylaxis and angioedema, have been reported in patients treated with canagliflozin; these reactions generally occurred within hours to days after initiating the drug. Discontinue use of canagliflozin if hypersensitivity reactions occur, and treat per standard of care; monitor until signs and symptoms resolve.

Canagliflozin is not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus and should not be used for the treatment of diabetic ketoacidosis (DKA). Canagliflozin significantly increases the risk of diabetic ketoacidosis in patients with type 1 diabetes. Reports of ketoacidosis, a serious, life-threatening condition requiring urgent hospitalization have been identified in postmarketing surveillance in patients with type 1 and type 2 diabetes mellitus receiving sodium glucose co-transporter-2 (SGLT2) inhibitors, including canagliflozin. Fatal cases of ketoacidosis have been reported in patients taking canagliflozin. The risk of ketoacidosis may be greater with higher doses. Risk factors for ketoacidosis also include patients with type 2 diabetes mellitus and pancreatic disorders such as, a history of pancreatitis, pancreatic insufficiency, or pancreatic surgery. Patients treated with canagliflozin who present with signs and symptoms consistent with dehydration and severe metabolic acidosis should be assessed for ketoacidosis regardless of presenting blood glucose levels, as ketoacidosis may be present even if blood glucose levels are less than 250 mg/dL. If ketoacidosis is suspected, discontinue canagliflozin, evaluate the patient, and institute prompt treatment. Treatment of ketoacidosis may require insulin, fluid and carbohydrate replacement. In many of the postmarketing reports, and particularly in patients with type 1 diabetes, the presence of ketoacidosis was not immediately recognized, and the institution of treatment was delayed because presenting blood glucose levels were below those typically expected for DKA (often less than 250 mg/dL). Signs and symptoms at presentation were consistent with dehydration and severe metabolic acidosis and included nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. In some but not all cases, factors predisposing to ketoacidosis such as insulin dose reduction, acute febrile illness, infection, reduced caloric intake, ketogenic diet, surgery, reduction in dose of exogenous insulin or discontinuation of exogenous insulin or insulin secretagogue, volume depletion, and alcohol abuse. Before initiating canagliflozin, consider factors in the patient history that may predispose to ketoacidosis including pancreatic insulin deficiency, caloric restriction, volume depletion, and alcohol abuse. Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 3 days after discontinuing canagliflozin; however there have been postmarketing reports of ketoacidosis and glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors. Based on the clinical situation, consider ketone monitoring in persons with type 1 diabetes mellitus and in others at risk for ketoacidosis. Assess for ketoacidosis regardless of presenting blood glucose levels in patients who present with signs and symptoms consistent with severe metabolic acidosis. If ketoacidosis is suspected, discontinue canagliflozin, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting canagliflozin. Withhold canagliflozin, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. For patients who undergo scheduled surgery, canagliflozin should be temporarily discontinued at least 3 days before surgery. Resume canagliflozin when the patient is clinically stable and has resumed oral intake. Educate patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue this product and seek medical attention immediately if signs and symptoms occur.

Canagliflozin causes intravascular volume contraction which may sometimes manifest as symptomatic hypotension or acute transient changes in serum creatinine. Patients with impaired renal function (eGFR 30 to less than 60 mL/minute/1.73 m2), elderly patients (age 75 years and older), and patients on loop diuretics may be at increased risk for volume depletion or hypotension. Volume status should be assessed and corrected before initiating canagliflozin in patients with one or more of these characteristics. Additionally, withholding food and fluids during surgical or other procedures may increase the risk for volume depletion, hypotension, and renal dysfunction. Canagliflozin should be temporarily discontinued while patients have restricted food and fluid intake. Monitor for signs and symptoms of hypotension or dehydration after initiating therapy.

Before the initiation of treatment and as clinically indicated, obtain an estimated glomerular filtration rate (eGFR) to assess renal function. Canagliflozin has not been studied in patients with end stage renal disease on dialysis or in renal impairment patients with an eGFR less than 30 mL/minute/1.73 m2, or in patients with renal failure. Patients with renal impairment who are treated for glycemic control may be more likely to experience hypotension and may be at a higher risk for kidney injury. Canagliflozin causes intravascular volume contraction and can cause acute kidney injury. There have been postmarketing reports of acute kidney injury, some requiring hospitalization and dialysis, in patients receiving canagliflozin. Initiation of canagliflozin may increase serum creatinine and decrease eGFR. In patients with moderate renal impairment, the increase in serum creatinine generally does not exceed 0.2 mg/dL, occurs within the first 6 weeks of starting therapy, and then stabilizes. Increases that do not fit this pattern should prompt further evaluation to exclude the possibility of acute kidney injury. The acute effect on eGFR reverses after treatment discontinuation suggesting acute hemodynamic changes may play a role in the renal function changes observed with canagliflozin. According to guidelines, randomized clinical outcome trials of advanced kidney disease or high cardiovascular disease risk with normal kidney function have not shown that SGLT2 inhibitors promote acute kidney injury. Despite these findings, the manufacturer recommends that before initiating canagliflozin, consider factors that may predispose patients to acute kidney injury including hypovolemia, chronic renal insufficiency, congestive heart failure, elderly age, pre-existing renal disease, and concomitant medications (e.g., diuretics, ACE inhibitors, ARBs, NSAIDs). Consider temporarily discontinuing canagliflozin in any setting of reduced oral intake (such as acute illness or fasting) or fluid losses (such as gastrointestinal illness or excessive heat exposure); monitor patients for signs and symptoms of acute kidney injury. If acute kidney injury occurs, discontinue canagliflozin promptly and institute treatment.

Canagliflozin is associated with an increase in risk of lower limb amputation. Results from the CANVAS and CANVAS-R studies have shown an increase in leg and foot amputations with canagliflozin in patients who had either established cardiovascular disease or who were at risk for cardiovascular disease. Amputations were mostly involving the toe and midfoot (99 out of 140 patients in both trials); amputations involving the leg, below and above the knee, were also observed (41 out of 140 patients in both trials). The risk of lower limb amputations over 1 year's time in the CANVAS study was 5.9 amputations per 1,000 patients treated with canagliflozin compared to 2.8 amputations per 1,000 patients treated with placebo. In the CANVAS-R study, the risk of lower limb amputations over 1 year's time was 7.5 amputations per 1,000 patients for canagliflozin compared to 4.2 amputations per 1,000 patients for placebo. In the CREDENCE trial, the rate of lower limb amputations associated with the use of canagliflozin 100 mg relative to placebo was 12.3 vs. 11.2 events per 1,000 patient-years, respectively. The risk of lower limb amputations has been observed at both the 100 mg and 300 mg doses. Some patients had more than 1 amputation, some involving both limbs. Lower limb infections, gangrene, diabetic foot ulcers, and ischemia were the most common precipitating medical events leading to an amputation. The risk of amputation was highest in patients with a baseline history of prior amputation, peripheral vascular disease, or peripheral neuropathy; therefore, before initiating therapy with canagliflozin, consider these factors that may predispose patients to the need for amputations. Also consider the patient's history of diabetic foot ulcers. Monitor patients for infection (including osteomyelitis) of the legs and feet and instruct patients to notify their health care professional immediately if they notice any new pain or tenderness, unusual sensations, skin color changes, sores or ulcers, or infection in their legs or feet. The patient should self-examine their feet daily in routine diabetes care, and a health care professional should routinely perform a complete foot exam.

Sodium-glucose co-transporter 2 (SGLT2) inhibitors such as canagliflozin may cause an increased risk for serious urinary tract infection (UTI), including urosepsis and pyelonephritis, and these cases can result in hospitalization. Patients should be told to report any signs of UTI and seek medical attention if they experience symptoms such as a feeling of burning when urinating or the need to urinate often or right away, pain in the lower part of the stomach area or pelvis, fever, or blood in the urine. Promptly treat if indicated if a UTI is suspected. Treatment with canagliflozin also increases the risk of genital mycotic infections. Use canagliflozin cautiously in patients with a history of genital fungal infections, including vaginitis or balanitis, and uncircumcised males since these patients were more likely to develop genital mycotic infections during treatment with canagliflozin. Monitor and treat appropriately if a genital mycotic infection occurs. All patients beginning therapy with a sodium-glucose co-transporter 2 (SGLT2) inhibitor or currently receiving canagliflozin should be closely monitored for a serious rare, life-threatening infection, called necrotizing fasciitis (tissue necrosis) of the perineum, also referred to as Fournier's gangrene. Patients should be warned to promptly seek medical attention if they experience any symptoms of tenderness, erythema, or swelling in the genital or perineal area, fever, or malaise, and such patients should be evaluated for necrotizing fasciitis. Cases have been reported in both females and males. Serious outcomes have included hospitalization, multiple surgeries, and death. If Fournier's gangrene is suspected, discontinue canagliflozin and institute prompt treatment with antibiotics and if necessary, surgical debridement. Closely monitor blood glucose levels, and provide appropriate alternative therapy for glycemic control.

Conditions that predispose patients to developing hypoglycemia may alter antidiabetic agent needs, and may require close monitoring during the use of canagliflozin. Conditions associated with hypoglycemia include debilitated physical condition, drug interactions, malnutrition, uncontrolled adrenal insufficiency, pituitary insufficiency or hypothyroidism. More frequent blood glucose monitoring may be necessary in patients with these conditions. Insulin and insulin secretagogues are also known to cause hypoglycemia. Canagliflozin can increase the risk of hypoglycemia when combined with insulin or an insulin secretagogue. Therefore, a lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with canagliflozin.

Conditions that predispose patients to developing hyperglycemia may alter canagliflozin efficacy. Hyperglycemia related conditions include drug interactions, female hormonal changes, high fever, severe psychological stress, and uncontrolled hypercortisolism or hyperthyroidism. More frequent blood glucose monitoring may be necessary in patients with these conditions.

The use of canagliflozin is not recommended in patients with severe hepatic disease (impairment) due to lack of data in these patients. In patients with mild or moderate hepatic impairment, no dosage adjustments are necessary.

An increased risk of bone fracture, occurring as early as 12 weeks after treatment initiation, was observed in patients using canagliflozin in the CANVAS trial. Consider factors that contribute to fracture risk (e.g., osteopenia; osteoporosis) before initiating canagliflozin therapy. In clinical trials, bone fractures occurred more frequently in patients receiving canagliflozin compared to patients receiving placebo. Fractures occurred as early as 12 weeks after canagliflozin initiation and were more likely to affect upper extremities. When trauma happened before a fracture, it was usually minor (e.g., falling from no more than standing height). In a clinical trial in 714 elderly patients, canagliflozin caused a more significant decrease in bone mineral density at the hip and lower spine compared to placebo.

Geriatric patients in clinical trials experienced a higher incidence of adverse reactions related to reduced intravascular volume (e.g., hypotension, postural dizziness, orthostatic hypotension, syncope, and dehydration), particularly with the 300 mg/day dose, compared to younger adult patients; those who were 75 years of age and older had the highest incidence of these events. In addition, smaller reductions in A1C with canagliflozin relative to placebo were seen in geriatric adults more than 65 years of age (-0.61% with canagliflozin 100 mg and -0.74% with canagliflozin 300 mg) compared to younger adults (-0.72% with canagliflozin 100 mg and -0.87% with canagliflozin 300 mg). Before initiating canagliflozin, assess renal function and volume status; correct pre-existing hypovolemia.

Based on animal data showing adverse renal effects, canagliflozin is not recommended during the second and third trimesters of pregnancy. Limited data with canagliflozin in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. In animal studies, irreversible adverse renal pelvic and tubule dilations were observed when canagliflozin was administered at an exposure of 0.5 times the 300 mg clinical human dose, based on AUC (exposure). During pregnancy, consider appropriate alternative therapies, especially during the second and third trimesters when the potential risks to human kidney development are of greatest concern. Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, stillbirth, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. The American College of Obstetricians and Gynecologists (ACOG) and the American Diabetes Association (ADA) continue to recommend human insulin as the standard of care in women with diabetes mellitus or gestational diabetes mellitus (GDM) requiring medical therapy; insulin does not cross the placenta.

Due to a potential for serious adverse reactions in the nursing infant, the use of canagliflozin is not recommended while breast-feeding. It is not known if canagliflozin is excreted in human milk. Canagliflozin is secreted in the milk of lactating rats reaching levels 1.4 times higher than that in maternal plasma. Data in juvenile rats directly exposed to canagliflozin showed risk to the developing kidney (renal pelvic and tubular dilatations) during maturation. Since human kidney maturation occurs in utero and during the first 2 years of life when lactational exposure may occur, there may be a risk to the developing human kidney. If canagliflozin is discontinued and blood glucose is not controlled on diet and exercise alone, insulin therapy should be considered. Other oral hypoglycemics may also be considered. Metformin monotherapy may be appropriate for some patients as available studies indicate low excretion in milk and that maternal use during breast-feeding is not expected to result in side effects to a healthy nursing infant. Some experts recommend using metformin with caution if the patient is breastfeeding a newborn or a premature neonate with reduced renal function. Because acarbose has limited systemic absorption, which results in minimal maternal plasma concentrations, clinically significant exposure via breast milk is not expected; therefore, this agent may be an alternative if postprandial glucose control is needed. Glyburide may be a suitable alternative since it was not detected in the breast milk of lactating women who received single and multiple doses of glyburide. If any oral hypoglycemics are used during breast-feeding, the nursing infant should be monitored for signs of hypoglycemia, such as increased fussiness or somnolence.

Monitoring of glycemic control with urine glucose tests and the 1,5 Anhydroglucitol assay (1,5-AG assay) is not recommended in patients receiving canagliflozin due to laboratory test interference. Use of urine glucose tests will result in positive urine glucose tests, and measurements of 1,5-AG are unreliable. Use alternative methods to monitor glycemic control.

For the treatment of type 2 diabetes mellitus as an adjunct to diet and exercise:
Oral dosage:
Adults: 100 mg PO once daily, initially. May increase dose to 300 mg PO once daily if needed. Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions.

For the reduction of cardiovascular mortality in persons with type 2 diabetes mellitus (T2DM) with established cardiovascular disease and to reduce the risk of end-stage kidney disease, doubling of serum creatinine, cardiovascular death, and reduction of heart failure hospitalizations in persons with T2DM and diabetic nephropathy with albuminuria more than 300 mg/day:
Oral dosage:
Adults: 100 mg PO once daily, initially. May increase the dose to 300 mg PO once daily if additional glycemic control is needed. Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions.

Therapeutic Drug Monitoring:
-Individualize glycemic goals based on a risk-benefit assessment.
-Use higher goals in patients with persistent hypoglycemia.
-Monitor post-prandial glucose concentrations if there is any inconsistency between pre-prandial glucose and A1C concentrations and to help assess basal-bolus regimens.

Blood glucose goals for adults with type 1 or type 2 diabetes :
-Pre-prandial = 80 to 130 mg/dL
-Peak post-prandial = less than 180 mg/dL

A1C goals for adults with type 1 or type 2 diabetes :
-Assess A1C at least 2 times a year in patients who are meeting treatment goals (and who have stable glycemic control). Perform the A1C test quarterly in patients whose therapy has changed or who are not meeting glycemic goals.
-In general, an A1C target is less than 7% in nonpregnant adults.
-A more stringent goal of less than 6.5% may be appropriate for selected individual patients if this can be achieved without significant hypoglycemia or other adverse effects.
-Less stringent goals (e.g., A1C less than 8%) may be appropriate for patients with a history of severe hypoglycemia, limited life expectancy, advanced microvascular/macrovascular complications, or extensive comorbid conditions.


Maximum Dosage Limits:
-Adults
300 mg/day PO.
-Geriatric
300 mg/day PO.
-Adolescents
Safety and efficacy have not been established.
-Children
Safety and efficacy have not been established.
-Infants
Not indicated.

Patients with Hepatic Impairment Dosing
No dosage adjustment is needed in patients with mild to moderate hepatic impairment. The use of canagliflozin has not been studied in patients with severe hepatic impairment and is therefore not recommended.

Patients with Renal Impairment Dosing
eGFR 60 mL/minute/1.73 m2 or more: No dosage adjustment needed.
eGFR 30 to 59 mL/minute/1.73 m2: Do not exceed 100 mg/day PO.
eGFR 20 to 29 mL/minute/1.73 m2: Not recommended for glycemic control; however, guidelines recommend use in all patients with T2DM and CKD for cardiovascular and renal protection regardless of glycemia or presence of albuminuria; once initiated canagliflozin can be continued at 100 mg PO once daily at lower levels of eGFR.
eGFR less than 20 mL/minute/1.73 m2: Do not initiate therapy; may continue if eGFR declines after initiation in patients with albuminuria unless not tolerated or kidney replacement therapy is initiated.

*non-FDA-approved indication

Acebutolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Acetaminophen; Chlorpheniramine; Dextromethorphan; Phenylephrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells.

Acetazolamide: (Minor) Carbonic anhydrase inhibitors may alter blood sugar. Both hyperglycemia and hypoglycemia have been described in patients treated with acetazolamide. This should be taken into consideration in patients with impaired glucose tolerance or diabetes mellitus who are receiving antidiabetic agents. Monitor blood glucose and for changes in glycemic control and be alert for evidence of an interaction.

Acrivastine; Pseudoephedrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors.

Albuterol; Budesonide: (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.

Aliskiren; Hydrochlorothiazide, HCTZ: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control.

Amiloride; Hydrochlorothiazide, HCTZ: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control.

Amphetamine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Amphetamine; Dextroamphetamine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Androgens: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.

Angiotensin II receptor antagonists: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Angiotensin-converting enzyme inhibitors: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin-converting enzyme (ACE) inhibitor use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Apalutamide: (Major) Increase the canagliflozin dose to 200 mg/day in persons who are tolerating canagliflozin 100 mg/day and receiving concomitant apalutamide. The canagliflozin dose may be further increased to 300 mg/day for persons with an eGFR of 60 mL/minute/1.73 m2 or more who require additional glycemic control; consider adding another antihyperglycemic agent for persons with an eGFR less than 60 mL/minute/1.73 m2 who require additional glycemic control. Canagliflozin is an UGT1A9 and UGT2B4 substrate, and apalutamide is an UGT inducer. Coadministration with a nonselective inducer of several UGT enzymes decreased canagliflozin exposure by 51%. This decrease in exposure may decrease canagliflozin efficacy.

Aripiprazole: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and SGLT2 inhibitor use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.

Articaine; Epinephrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion.

Atazanavir: (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors. A possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. Patients on antidiabetic therapy should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.

Atazanavir; Cobicistat: (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors.

A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Atenolol; Chlorthalidone: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control. (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas.

Fosphenytoin: (Major) Increase the canagliflozin dose to 200 mg/day in persons who are tolerating canagliflozin 100 mg/day and receiving concomitant fosphenytoin. The canagliflozin dose may be further increased to 300 mg/day for persons with an eGFR of 60 mL/minute/1.73 m2 or more who require additional glycemic control; consider adding another antihyperglycemic agent for persons with an eGFR less than 60 mL/minute/1.73 m2 who require additional glycemic control. Canagliflozin is an UGT1A9 and UGT2B4 substrate, and fosphenytoin is an UGT inducer. Coadministration with a nonselective inducer of several UGT enzymes decreased canagliflozin exposure by 51%. This decrease in exposure may decrease canagliflozin efficacy.

Constituents in garlic might have some antidiabetic activity, and may increase serum insulin levels and increase glycogen storage in the liver. Monitor blood glucose and glycemic control. Patients with diabetes should inform their health care professionals of their intent to ingest garlic dietary supplements. Some patients may require adjustment to their hypoglycemic medications over time. One study stated that additional garlic supplementation (0.05 to 1.5 grams PO per day) contributed to improved blood glucose control in patients with type 2 diabetes mellitus within 1 to 2 weeks, and had positive effects on total cholesterol and high/low density lipoprotein regulation over time. It is unclear if hemoglobin A1C is improved or if improvements are sustained with continued treatment beyond 24 weeks. Other reviews suggest that garlic may provide modest improvements in blood lipids, but few studies demonstrate decreases in blood glucose in diabetic and non-diabetic patients. More controlled trials are needed to discern if garlic has an effect on blood glucose in patients with diabetes. When garlic is used in foods or as a seasoning, or at doses of 50 mg/day or less, it is unlikely that blood glucose levels are affected to any clinically significant degree.

Labetalol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia.

Lonapegsomatropin: (Moderate) Patients with diabetes mellitus should be monitored closely during somatropin (recombinant rhGH) therapy. Antidiabetic drugs (e.g., insulin or oral agents) may require adjustment when somatropin therapy is instituted in these patients. Growth hormones, such as somatropin, may decrease insulin sensitivity, leading to glucose intolerance and loss of blood glucose control. Therefore, glucose levels should be monitored periodically in all patients treated with somatropin, especially in those with risk factors for diabetes mellitus.

Loop diuretics: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant loop diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving loop diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Loop diuretics tend to produce hyperglycemia and may lead to loss of glycemic control.

Lopinavir; Ritonavir: (Major) Increase the canagliflozin dose to 200 mg/day in persons who are tolerating canagliflozin 100 mg/day and receiving concomitant ritonavir. The canagliflozin dose may be further increased to 300 mg/day for persons with an eGFR of 60 mL/minute/1.73 m2 or more who require additional glycemic control; consider adding another antihyperglycemic agent for persons with an eGFR less than 60 mL/minute/1.73 m2 who require additional glycemic control. Canagliflozin is an UGT1A9 and UGT2B4 substrate, and ritonavir is an UGT inducer. Coadministration with a nonselective inducer of several UGT enzymes decreased canagliflozin exposure by 51%. This decrease in exposure may decrease canagliflozin efficacy. (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors, such as lopinavir. A possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. Patients on antidiabetic therapy should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.

Loratadine; Pseudoephedrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Losartan: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Losartan; Hydrochlorothiazide, HCTZ: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control. (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Lumateperone: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and SGLT2 inhibitor use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.

Lurasidone: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and SGLT2 inhibitor use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.

Mafenide: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and sulfonamide use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Magnesium Salicylate: (Moderate) Monitor blood glucose during concomitant canagliflozin and salicylate use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Mecasermin, Recombinant, rh-IGF-1: (Moderate) Use caution in combining mecasermin, recombinant, rh-IGF-1 or mecasermin rinfabate (rh-IGF-1/rh-IGFBP-3) with antidiabetic agents. Patients should be advised to eat within 20 minutes of mecasermin administration. Glucose monitoring is important when initializing or adjusting mecasermin therapies, when adjusting concomitant antidiabetic therapy, and in the event of hypoglycemic symptoms. An increased risk for hypoglycemia is possible. The hypoglycemic effect induced by IGF-1 activity may be exacerbated. The amino acid sequence of mecasermin (rh-IGF-1) is approximately 50 percent homologous to insulin and cross binding with either receptor is possible. Treatment with mecasermin has been shown to improve insulin sensitivity and to improve glycemic control in patients with either Type 1 or Type 2 diabetes mellitus when used alone or in conjunction with insulins.

Medroxyprogesterone: (Minor) Progestins can impair glucose tolerance. Patients receiving antidiabetic agents should be closely monitored for signs indicating changes in diabetic control when therapy with progestins is instituted or discontinued.

Methamphetamine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Methazolamide: (Minor) Carbonic anhydrase inhibitors may alter blood sugar. Both hyperglycemia and hypoglycemia have been described in patients treated with acetazolamide. This should be taken into consideration in patients with impaired glucose tolerance or diabetes mellitus who are receiving antidiabetic agents. Monitor blood glucose and for changes in glycemic control and be alert for evidence of an interaction.

Methenamine; Sodium Salicylate: (Moderate) Monitor blood glucose during concomitant canagliflozin and salicylate use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Methylphenidate: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Methylprednisolone: (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.

Methyltestosterone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.

Metolazone: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control.

Metoprolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Metoprolol; Hydrochlorothiazide, HCTZ: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control.

Midodrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Moexipril: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin-converting enzyme (ACE) inhibitor use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Mometasone: (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.

Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.

Monoamine oxidase inhibitors: (Moderate) Monitor blood glucose during concomitant canagliflozin and monoamine oxidase inhibitor (MAOI) use; a canagliflozin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Moxifloxacin: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and quinolone use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Nadolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Nebivolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

(Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Nelfinavir: (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors. A possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. Patients on antidiabetic therapy should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.

Niacin, Niacinamide: (Moderate) Niacin (nicotinic acid) interferes with glucose metabolism and can result in hyperglycemia. Changes in glycemic control can usually be corrected through modification of hypoglycemic therapy. Monitor patients taking antidiabetic agents for changes in glycemic control if niacin (nicotinic acid) is added or deleted to the medication regimen. Dosage adjustments may be necessary.

Nicotine: (Minor) Monitor blood glucose concentrations for needed antidiabetic agent dosage adjustments in diabetic patients whenever a change in either nicotine intake or smoking status occurs. Nicotine activates neuroendocrine pathways (e.g., increases in circulating cortisol and catecholamine concentrations) and may increase plasma glucose. The cessation of nicotine therapy or tobacco smoking may result in a decrease in blood glucose.

Nirmatrelvir; Ritonavir: (Major) Increase the canagliflozin dose to 200 mg/day in persons who are tolerating canagliflozin 100 mg/day and receiving concomitant ritonavir. The canagliflozin dose may be further increased to 300 mg/day for persons with an eGFR of 60 mL/minute/1.73 m2 or more who require additional glycemic control; consider adding another antihyperglycemic agent for persons with an eGFR less than 60 mL/minute/1.73 m2 who require additional glycemic control. Canagliflozin is an UGT1A9 and UGT2B4 substrate, and ritonavir is an UGT inducer. Coadministration with a nonselective inducer of several UGT enzymes decreased canagliflozin exposure by 51%. This decrease in exposure may decrease canagliflozin efficacy.

Norepinephrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Norethindrone Acetate; Ethinyl Estradiol; Ferrous fumarate: (Minor) Patients receiving antidiabetic agents should be periodically monitored for changes in glycemic control when hormone therapy is instituted or discontinued. Estrogens can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day in combined oral contraceptives (COCs), which are not commonly used in practice since the marketing of lower dose COCs, patches, injections and rings. The presence or absence of a concomitant progestin may influence the significance of any hormonal effect on glucose homeostasis. (Minor) Progestins can impair glucose tolerance. Patients receiving antidiabetic agents should be closely monitored for signs indicating changes in diabetic control when therapy with progestins is instituted or discontinued.

Norgestrel: (Minor) Progestins can impair glucose tolerance. Patients receiving antidiabetic agents should be closely monitored for signs indicating changes in diabetic control when therapy with progestins is instituted or discontinued.

Octreotide: (Moderate) Monitor patients receiving octreotide concomitantly with insulin or other antidiabetic agents for changes in glycemic control and adjust doses of these medications accordingly. Octreotide alters the balance between the counter-regulatory hormones of insulin, glucagon, and growth hormone, which may result in hypoglycemia or hyperglycemia. The hypoglycemia or hyperglycemia which occurs during octreotide acetate therapy is usually mild but may result in overt diabetes mellitus or necessitate dose changes in insulin or other hypoglycemic agents. In patients with concomitant type1 diabetes mellitus, octreotide is likely to affect glucose regulation, and insulin requirements may be reduced. Symptomatic hypoglycemia, which may be severe, has been reported in type 1 diabetic patients. In Type 2 diabetes patients with partially intact insulin reserves, octreotide administration may result in decreases in plasma insulin levels and hyperglycemia.

Ofloxacin: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and quinolone use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Olanzapine: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and SGLT2 inhibitor use. Atypical antipsychotic therapy may aggravate diabetes mellitus.

Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control. (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Olmesartan; Hydrochlorothiazide, HCTZ: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics.

Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.

Orlistat: (Minor) Weight-loss may affect glycemic control in patients with diabetes mellitus. In many patients, glycemic control may improve. A reduction in dose of oral hypoglycemic medications may be required in some patients taking orlistat. Monitor blood glucose and glycemic control and adjust therapy as clinically indicated.

Oxandrolone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.

Oxcarbazepine: (Major) Increase the canagliflozin dose to 200 mg/day in persons who are tolerating canagliflozin 100 mg/day and receiving concomitant oxcarbazepine. The canagliflozin dose may be further increased to 300 mg/day for persons with an eGFR of 60 mL/minute/1.73 m2 or more who require additional glycemic control; consider adding another antihyperglycemic agent for persons with an eGFR less than 60 mL/minute/1.73 m2 who require additional glycemic control. Canagliflozin is an UGT1A9 and UGT2B4 substrate, and oxcarbazepine is an UGT inducer. Coadministration with a nonselective inducer of several UGT enzymes decreased canagliflozin exposure by 51%. This decrease in exposure may decrease canagliflozin efficacy.

Oxymetholone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens.

Paliperidone: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and SGLT2 inhibitor use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.

Pasireotide: (Moderate) Monitor blood glucose levels regularly in patients with diabetes, especially when pasireotide treatment is initiated or when the dose is altered. Adjust treatment with antidiabetic agents as clinically indicated. Pasireotide inhibits the secretion of insulin and glucagon. Patients treated with pasireotide may experience either hypoglycemia or hyperglycemia.

Pegvisomant: (Moderate) Monitor blood glucose levels regularly in patients with diabetes, especially when pegvisomant treatment is initiated or when the dose is altered. Adjust treatment with antidiabetic agents as clinically indicated. Pegvisomant increases sensitivity to insulin by lowering the activity of growth hormone, and in some patients glucose tolerance improves with treatment. Patients with diabetes treated with pegvisomant and antidiabetic agents may be more likely to experience hypoglycemia.

Pentamidine: (Moderate) Pentamidine can be harmful to pancreatic cells. This effect may lead to hypoglycemia acutely, followed by hyperglycemia with prolonged pentamidine therapy. Patients on antidiabetic agents should be monitored for the need for dosage adjustments during the use of pentamidine.

Perindopril: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin-converting enzyme (ACE) inhibitor use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Patients who are taking antidiabetic agents should be closely monitored for worsening glycemic control when any of these antipsychotics is instituted.

Perphenazine; Amitriptyline: (Minor) Phenothiazines, especially chlorpromazine, may increase blood glucose concentrations. Hyperglycemia and glycosuria have been reported. Patients who are taking antidiabetic agents should be closely monitored for worsening glycemic control when any of these antipsychotics is instituted.

Phendimetrazine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking SGLT2 inhibitors. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.

Canagliflozin is an UGT1A9 and UGT2B4 substrate, and phenytoin is an UGT inducer. Coadministration with a nonselective inducer of several UGT enzymes decreased canagliflozin exposure by 51%. This decrease in exposure may decrease canagliflozin efficacy.

Pindolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Valsartan: (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Valsartan; Hydrochlorothiazide, HCTZ: (Major) Assess and correct volume status before initiating canagliflozin in persons receiving concomitant thiazide diuretics. Monitor for signs and symptoms of volume depletion and loss of glycemic control after initiating therapy due to increased risk for volume depletion or hypotension and loss of blood glucose control. Persons receiving thiazide diuretics may be at increased risk for volume depletion or hypotension with concomitant canagliflozin therapy. Thiazide diuretics tend to produce hyperglycemia and may lead to loss of glycemic control. (Moderate) Monitor blood glucose during concomitant SGLT2 inhibitor and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Vitamin B Complex Supplements: (Moderate) Niacin (nicotinic acid) interferes with glucose metabolism and can result in hyperglycemia. Changes in glycemic control can usually be corrected through modification of hypoglycemic therapy. Monitor patients taking antidiabetic agents for changes in glycemic control if niacin (nicotinic acid) is added or deleted to the medication regimen. Dosage adjustments may be necessary.

Vonoprazan; Amoxicillin; Clarithromycin: (Moderate) The concomitant use of clarithromycin and antidiabetic agents can result in significant hypoglycemia. Careful monitoring of blood glucose is recommended.

Ziprasidone: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and SGLT2 inhibitor use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.

Canagliflozin is an inhibitor of sodium-glucose co-transporter 2 (SGLT2), the transporter responsible for reabsorbing the majority of glucose filtered by the tubular lumen in the kidney. SGLT2 is expressed in the proximal renal tubules. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RTG), and thereby increases urinary glucose excretion, improving blood glucose control. In studies with single and multiple oral doses, dose-dependent decreases in the RTG and increases in urinary glucose excretion were observed within the first day of dosing. Canagliflozin 100 mg/day and 300 mg/day suppressed RTG throughout the 24-hour period; maximal suppression occurred with the 300 mg/day oral dose. Reductions in RTG led to increases in mean urinary glucose excretion of approximately 100 grams/day in subjects treated with canagliflozin 100 mg/day or 300 mg/day. This urinary glucose excretion with canagliflozin also results in increased urinary volume. When the drug was given over a 16-day dosing period, reductions in RTG and increases in urinary glucose excretion were observed over the dosing period. In single-dose studies, canagliflozin 300 mg before a mixed-meal delayed intestinal glucose absorption and reduced postprandial blood glucose.

Canagliflozin is administered orally. The drug is well distributed into tissues. After a single IV infusion, the mean steady-state volume of distribution was 83.5 L. Canagliflozin is 99% bound plasma proteins, mainly to albumin. Protein binding is independent of plasma concentrations. Canagliflozin is mainly metabolized by O-glucuronidation via UGT1A9 and UGT2B4 to 2 inactive O-glucuronide metabolites. CYP3A4-mediated (oxidative) metabolism is approximately 7% in humans. Following administration of a single oral radioactive dose, 41.5%, 7%, and 3.2% of the administered dose was recovered in feces as canagliflozin, a hydroxylated metabolite, and an O-glucuronide metabolite, respectively. Enterohepatic circulation of canagliflozin was negligible. Approximately 33% of the administered radioactive dose was excreted in urine, mainly as O-glucuronide metabolites (30.5%). Less than 1% of the dose was excreted as unchanged canagliflozin in urine. Renal clearance of 100 mg and 300 mg oral doses ranged from 1.30 to 1.55 mL/minute. Mean systemic clearance was approximately 192 mL/minute following IV administration.

Affected Cytochrome P450 (CYP450) enzymes and drug transporters: UGT1A9, UGT2B4, P-glycoprotein (P-gp)
Canagliflozin is mainly metabolized via O-glucuronidation by a UGT1A9 and UGT2B4. CYP3A4-mediated metabolism is minimal in humans. Only inducers of these UGT subtypes are expected to have a significant effect on canagliflozin exposure. Canagliflozin is a weak inhibitor of P-glycoprotein (P-gp) and is a substrate of drug transporters P-gp and MRP2; however, only a potential for pharmacokinetic interaction with digoxin has been considered relevant due to these effects.

Canagliflozin did not induce CYP450 enzyme expression (CYP3A4, CYP2C9, CYP2C19, CYP2B6, and CYP1A2) in cultured human hepatocytes. It did not inhibit the CYP450 isoenzymes (CYP1A2, CYP2A6, CYP2C19, CYP2D6, or CYP2E1) and weakly inhibited CYP2B6, CYP2C8, CYP2C9, and CYP3A4 based on in vitro studies with human hepatic microsomes. Clinically relevant interactions with drugs affected by these CYP enzymes have not been reported.


-Route-Specific Pharmacokinetics
Oral Route
The mean absolute oral bioavailability of canagliflozin is approximately 65%. Administration of canagliflozin with a high-fat meal results in no change to the pharmacokinetics. Thus, canagliflozin may be administered with or without food. However, based on the potential to reduce postprandial plasma glucose excursions due to delayed intestinal glucose absorption, it is recommended that canagliflozin be taken before the first meal of the day. Following single-dose oral administration of canagliflozin 100 mg and 300 mg, peak plasma concentrations (median Tmax) occur within 1 to 2 hours post-dose. Plasma peak concentrations (Cmax) and the AUC of canagliflozin increase in a dose-proportional manner from 50 mg to 300 mg.


-Special Populations
Hepatic Impairment
Plasma protein binding is not meaningfully altered in patients with hepatic impairment. When compared to subjects with normal hepatic function, the differences for the Cmax and AUCinfinity of canagliflozin in patients with Child-Pugh class A (mild) hepatic impairment and Child-Pugh class B (moderate) hepatic impairment are not considered to be clinically meaningful. There is no clinical experience in patients with Child-Pugh class C (severe) hepatic impairment.

Renal Impairment
Canagliflozin has not been studied in patients with severe renal impairment and those with end stage renal disease (ESRD) on dialysis. The clinical response to canagliflozin declines with increasing severity of renal impairment. Renal impairment did not affect the Cmax of canagliflozin 200 mg, and plasma protein binding is not altered. When the plasma AUC of canagliflozin was compared between healthy subjects and patients with various degrees of renal impairment, the plasma AUC increased with increasing severity of renal impairment; however, the plasma AUC of canagliflozin was similar for patients with ESRD and healthy adult subjects. The results were not considered clinically relevant. Canagliflozin is negligibly removed by hemodialysis.
