This medication is an antibiotic used to treat a wide variety of bacterial infections.

How To Use

Take twice daily by mouth or as directed by your doctor. This medication works best on an empty stomach one hour before or two hours after meals. Take each dose with a full glass of water. Drink plenty of fluids while taking this medication. If stomach upset occurs, it may be taken with food. Take this medication 2 hours before or 2 hours after taking any medications containing magnesium, aluminum, or calcium. Some examples include quinapril, didanosine, vitamins/minerals, or antacids. Sucralfate, bismuth subsalicylate, iron, and zinc are also included. These medications bind with ofloxacin preventing its full absorption. It is not known whether or not milk or dairy products prevent absorption of ofloxacin. Therefore, as a precaution, do not eat/drink dairy products within 2 hours before or after taking ofloxacin. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Do this by taking the medication at evenly spaced intervals throughout the day and night. Continue to take this medication until the full prescribed amount is finished even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow resulting in a relapse of the infection.
