What should I avoid while taking gemifloxacin (Factive)?
You may be taking certain other medicines that 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);
- the ulcer medicine sucralfate (Carafate);
- didanosine (Videx) powder or chewable tablets; or
- vitamin or mineral supplements that contain iron or zinc.
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.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop taking gemifloxacin and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Gemifloxacin may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
