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

How To Use

Take each dose with a full glass of water. This drug may be taken with or without food. Drink plenty of fluids while taking this medication. Take this medication 2 hours before or 4 hours after taking any medications containing magnesium or aluminum. Some examples include quinapril, didanosine, vitamins/minerals, and antacids. Sucralfate bismuth subsalicylate, iron, and zinc are also included. These medications bind with lomefloxacin preventing its full absorption. 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.
