What It's For & How To Take
Moxifloxacin is a quinolone-type antibiotic that works by blocking the growth of bacteria. Moxifloxacin is used to treat a wide variety of bacterial infections.
Do not take an antibiotic without first being seen by a prescriber. Not all antibiotics work for all types of infections. If you take an antibiotic that is not prescribed for you, the condition might get worse.
Moxifloxacin 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.
Moxifloxacin is usually taken once daily, or as directed by your physician. Take moxifloxacin at least 2 hours before or 6 hours after antacids such as Tums™, Maalox™ or Mylanta™. Some foods high in calcium such as yogurt or milk may also block moxifloxacin from working. Ask your pharmacist what you can and can’t have with this medication. Take moxifloxacin with a full glass of water.
Take this medication at evenly spaced intervals. Antibiotics work best when a constant level of the medication is maintained in the body.
If you forget to take a dose, take it as soon as you remember. If it is near the time for your next dose, skip it and continue with your normal dose time. Unless directed otherwise, do not take a double dose to make up the missed dose.
Take this medication until it is all gone, even if you are feeling better and the symptoms are gone. If you stop taking your antibiotic, the infection might come back and may be harder to treat.
