Why is Avelox prescribed:
Avelox is used to treat certain infections such as pneumonia, bronchitis, and sinus, skin, and abdominal (stomach area) infections caused by bacteria. Avelox is in a class of antibiotics called fluoroquinolones. Avelox works by killing the bacteria that cause infections. Antibiotics will not work against colds, flu, or other viral infections.
How should Avelox be used:
Avelox comes as tablet to take by mouth. Avelox is usually taken with or without food once a day for 5 to 21 days. The length of treatment depends on the type of infection being treated. Your doctor will tell you how long to take Avelox. Take Avelox at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Avelox exactly as directed. Do not take more or less of Avelox or take Avelox more often than prescribed by your doctor. You should begin to feel better during the first few days of treatment with Avelox. If your symptoms do not improve or if they get worse, call your doctor. Take Avelox until you finish the prescription, even if you feel better. Do not stop taking Avelox unless you experience the symptoms of tendinitis or tendon rupture described in the IMPORTANT WARNING section or the symptoms of allergic reaction described in the SIDE EFFECTS section. If you stop taking Avelox too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Other uses for Avelox
Avelox is also sometimes used to treat tuberculosis (TB) and endocarditis (infection of the heart lining and valves) when other medications cannot be used. Avelox also may be used to treat or prevent anthrax (a serious infection that may be spread on purpose as part of a bioterror attack) in people who may have been exposed to anthrax germs in the air if other medications are not available for this purpose. Talk to your doctor about the risks of using this medication for your condition. Avelox may be prescribed for other uses; ask your doctor or pharmacist for more information.
