What is the most important information I should know about levofloxacin?

You should not use this medication if you are allergic to levofloxacin or similar antibiotics such as ciprofloxacin (Cipro), moxifloxacin (Avelox), ofloxacin (Floxin), norfloxacin (Noroxin), lomefloxacin (Maxaquin), and others.

Before taking levofloxacin, tell your doctor if you have kidney or liver disease, myasthenia gravis, joint problems, seizures or epilepsy, diabetes, low levels of potassium in your blood (hypokalemia), or a personal or family history of "Long QT syndrome."

Avoid taking antacids, vitamin or mineral supplements, sucralfate (Carafate), or didanosine (Videx) powder or chewable tablets within 2 hours before or after you take levofloxacin. These other medicines can make levofloxacin much less effective when taken at the same time.

Taking levofloxacin can make your skin more sensitive to sunlight. Avoid exposure to sunlight, sun lamps, or tanning beds.

Levofloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles' tendon of the heel. These effects may be more likely to occur if you are over 60, if you take an oral steroid medication, or if you have had a kidney, heart, or lung transplant. Stop taking levofloxacin and call your doctor at once if you have sudden pain, swelling, tenderness, stiffness, or movement problems in any of your joints. Rest the joint until you receive medical care or instructions.

Do not share this medication with another person (especially a child), even if they have the same symptoms you have.

What is levofloxacin?

Levofloxacin is in a group of antibiotics called fluoroquinolones (flor-o-KWIN-o-lones). Levofloxacin fights bacteria in the body.

Levofloxacin is used to treat bacterial infections of the skin, sinuses, kidneys, bladder, or prostate. Levofloxacin is also used to treat bacterial infections that cause bronchitis or pneumonia, and to treat people who have been exposed to anthrax.

Levofloxacin may also be used for other purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking levofloxacin?

You should not use this medication if you are allergic to levofloxacin or other fluoroquinolones such as ciprofloxacin (Cipro), moxifloxacin (Avelox), ofloxacin (Floxin), norfloxacin (Noroxin), lomefloxacin (Maxaquin), and others.

Before taking levofloxacin, tell your doctor if you have a heart rhythm disorder, especially if you are being treated with one of these medications: quinidine (Cardioquin, Quinidex, Quinaglute), disopyramide (Norpace), bretylium (Bretylol), procainamide (Pronestyl, Procan SR), amiodarone (Cordarone, Pacerone), or sotalol (Betapace).

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before you take levofloxacin, tell your doctor if you have:

a history of allergic reaction to an antibiotic;
myasthenia gravis;
joint problems;
kidney or liver disease;
seizures or epilepsy;
diabetes;
