What is moxifloxacin (Avelox)?
Moxifloxacin is a fluoroquinolone (floor-o-KWIN-o-lone) antibiotic that fights bacteria in the body.
Moxifloxacin is used to treat different types of bacterial infections of the skin, sinuses, lungs, or stomach.

What is the most important information I should know about moxifloxacin (Avelox)?
Moxifloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles' tendon of the heel. This effect may be more likely to occur if you are over 60, if you use steroid medication, or if you have had a kidney, heart, or lung transplant.
Call your doctor at once if you have sudden pain, swelling, bruising, tenderness, stiffness, or movement problems in any of your joints. Rest the joint until you receive medical care or instructions.
What should I discuss with my healthcare provider before taking moxifloxacin (Avelox)?
Moxifloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles' tendon of the heel. This can happen during treatment or up to several months after you stop taking moxifloxacin. Tendon problems may be more likely to occur if you are over 60, if you take steroid medication, or if you have had a kidney, heart, or lung transplant.
To make sure moxifloxacin is safe for you, tell your doctor if you have ever had:
- tendon problems, arthritis or other joint problems (especially in children);
- myasthenia gravis or other nerve-muscle disorder;
- a heart rhythm disorder (especially if you take medication to treat it);
- long QT syndrome (in you or a family member);
- trouble swallowing pills;
- liver or kidney disease;
- a seizure;
- low levels of potassium in your blood (hypokalemia); or
- if you use a blood thinner (warfarin, Coumadin, Jantoven) and have "INR" or prothrombin time tests.
Moxifloxacin is not approved for use by anyone younger than 18 years old.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Moxifloxacin can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.
How should I take moxifloxacin (Avelox)?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take moxifloxacin with water, and drink extra fluids to keep your kidneys working properly.
Moxifloxacin may be taken with or without food, but take it at the same time each day.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Moxifloxacin will not treat a viral infection such as the flu or a common cold.
Do not share this medicine with another person, even if they have the same symptoms you have.
Store at room temperature away from moisture and heat.
What happens if I miss a dose (Avelox)?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose (Avelox)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking moxifloxacin (Avelox)?
Do not take moxifloxacin with dairy products such as milk or yogurt, or with calcium-fortified juice. You may eat or drink these products as part of a regular meal, but do not use them alone when taking moxifloxacin. They could make the medication less effective.
Moxifloxacin may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Avoid exposure to sunlight or tanning beds. Moxifloxacin can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors. Call your doctor if you have severe burning, redness, itching, rash, or swelling after being in the sun.
What other drugs will affect moxifloxacin (Avelox)?
Some medicines can make moxifloxacin much less effective when taken at the same time. If you take any of the following medicines, take your moxifloxacin dose 4 hours before or 8 hours after you take the other medicine:
- antacids that contain magnesium or aluminum (such as Maalox, Mylanta, or Rolaids), or the ulcer medicine sucralfate (Carafate);
- didanosine (Videx) powder or chewable tablets; or
- vitamin or mineral supplements that contain aluminum, iron, magnesium, or zinc.
Tell your doctor about all your current medicines and any you start or stop using, especially:
- a diuretic or "water pill";
- heart rhythm medication;
- medicine to treat depression or mental illness; or
- NSAIDs (nonsteroidal anti-inflammatory drugs)--aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
