What is Factive (gemifloxacin)?
Gemifloxacin is a fluoroquinolone (flor-o-KWIN-o-lone) antibiotic that fights bacteria in the body.
Gemifloxacin is used to treat different types of bacterial infections in the lungs.
Fluoroquinolone antibiotics can cause serious or disabling side effects. Gemifloxacin should be used only for infections that cannot be treated with a safer antibiotic.
Gemifloxacin may also be used for purposes not listed in this medication guide.
What is the most important information I should know about Factive (gemifloxacin)?
Gemifloxacin may cause swelling or tearing of a tendon, especially if you are over 60, if you take steroid medication, or if you have had a kidney, heart, or lung transplant.

You should not use this medicine if you are allergic to gemifloxacin or other fluoroquinolones (ciprofloxacin, levofloxacin, moxifloxacin, ofloxacin, norfloxacin, and others).
To make sure gemifloxacin is safe for you, tell your doctor if you have:
tendon problems, arthritis or other joint problems;

a personal or family history of long QT syndrome;
trouble swallowing pills;
liver or kidney disease;
a history of epilepsy or other seizure disorder;
a nerve disorder;
low levels of magnesium or potassium in your blood; or

Gemifloxacin 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. This can happen during treatment or up to several months after you stop taking gemifloxacin. Tendon problems may be more likely to occur if you are over 60, if you take steroid medication, or if you have had a kidney, heart, or lung transplant.

How should I take Factive (gemifloxacin)?
Gemifloxacin is usually taken once per day for 5 to 7 days. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Gemifloxacin may be taken with or without food, but take it at the same time each day.
Do not chew a gemifloxacin tablet. Swallow it whole.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared.

What should I avoid while taking Factive (gemifloxacin)?
Do not take gemifloxacin with dairy products such as milk or yogurt, or with calcium-fortified juice. You may eat or drink these products as part of a regular meal, but do not use them alone when taking gemifloxacin. They could make the medication less effective.
Certain other medicines should not be taken at the same time as gemifloxacin. Avoid taking the following medicines within 3 hours before or 2 hours after you take gemifloxacin. These other medicines can make gemifloxacin much less effective when taken at the same time:
antacids that contain magnesium or aluminum (such as Maalox, Mylanta, or Rolaids), or the ulcer medicine sucralfate (Carafate);
didanosine (Videx) powder or chewable tablets; or
vitamin or mineral supplements that contain iron or zinc.
Gemifloxacin may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Avoid exposure to sunlight or tanning beds. Gemifloxacin can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors. Call your doctor if you have severe burning, redness, itching, rash, or swelling after being in the sun.
