How should I take grepafloxacin (Raxar)?

Take grepafloxacin exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.

Take each dose with a full glass of water (8 ounces). Drink several extra glasses of fluid each day to prevent the formation of grepafloxacin crystals in your urine.

Grepafloxacin may be taken with or without food.

Take grepafloxacin at evenly spaced intervals. Follow your doctor's instructions.

Do not take antacids that contain magnesium or aluminum (e.g., Tums or Rolaids), the ulcer medicine sucralfate (Carafate), or vitamin or mineral supplements that contain iron or zinc for a minimum of 4 hours before or 4 hours after a dose of grepafloxacin. Taking antacids, sucralfate, or vitamin or mineral supplements too close to a dose of grepafloxacin can greatly decrease the effects of the antibiotic.

Take all of the grepafloxacin that has been prescribed for you even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated.
