Levofloxacin

Pronounced

"lev-oh-FLOX-uh-sin"

Uses

Levofloxacin is used to treat a variety of bacterial infections. This medication belongs to a class of drugs known as quinolone antibiotics. It works by stopping the growth of bacteria.

This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.

Warning

Quinolone antibiotics (including levofloxacin) may cause serious and possibly permanent tendon damage (such as tendonitis, tendon rupture), nerve problems in the arms and legs (peripheral neuropathy), and nervous system problems. Get medical help right away if you have any of the following symptoms: pain/numbness/burning/tingling/weakness in your arms/hands/legs/feet, changes in how you sense touch/pain/temperature/vibration/body position, severe/lasting headache, vision changes, shaking (tremors), seizures, mental/mood changes (such as agitation, anxiety, confusion, hallucinations, depression, rare thoughts of suicide).

Tendon damage may occur during or after treatment with this medication. Stop exercising, rest, and get medical help right away if you develop joint/muscle/tendon pain or swelling. Your risk for tendon problems is greater if you are over 60 years of age, if you are taking corticosteroids (such as prednisone), or if you have a kidney, heart, or lung transplant.

This medication may make a certain muscle condition (myasthenia gravis) worse. Tell your doctor right away if you have new or worsening muscle weakness (such as drooping eyelids, unsteady walk) or trouble breathing.

Discuss the risks and benefits with your doctor before using this medication.
