• Avelox is an antibiotic used to treat adults with bacterial infections of the lungs, sinuses, skin, and intra-abdominal area (inner belly). It does not work for viral infections. This medication belongs to a class of drugs called quinolone antibiotics. It works by stopping the growth of bacteria.

How should you take this medication?

• Take this medication by mouth, with or without food, usually once daily or as directed by your doctor. Use each oral dose with a full glass of water. Drink plenty of fluids while using this drug unless your doctor tells you otherwise.
   
• Certain other medicines you may be using can decrease the effectiveness of moxifloxacin and must be used at least 4 hours after or 8 hours before you use moxifloxacin. Some examples include quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), sucralfate, vitamins/minerals, and antacids.
   
• If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule.
