In this session, we will be discussing the consumer medication information for levofloxacin, trade name LevaquinTM.
What it’s for & How to take
Levofloxacin is a quinolone-type antibiotic that works by blocking the growth of bacteria. Levofloxacin is used to treat a wide variety of bacterial infections.

Levofloxacin will not work to treat the common cold or the flu. This antibiotic may not be effective if it has been overused in conditions that are not related to bacterial infections.
Levofloxacin is usually prescribed to be taken once daily, or as directed by your physician. Take levofloxacin at least 2 hours before or 6 hours after antacids such as TumsTM, MaaloxTM or MylantaTM. Some foods high in calcium such as yogurt or milk may also block levofloxacin from working. Ask your pharmacist what you can and can’t have with this medication. Take levofloxacin with a full glass of water.
