Biaxin is an antibiotic used to treat certain bacterial infections, including strep throat, pneumonia, sinusitis (inflammation of the sinuses), tonsillitis (inflammation of the tonsils), acute middle ear infections, acute flare-ups of chronic bronchitis, and skin infections in adults.
Biaxin can also be combined with other medicines to treat duodenal ulcers caused by Helicobacter pylori bacteria in adults.
In children, Biaxin tablets and granules (for oral suspension) are used to treat bacterial infections, including sore throat and tonsillitis, pneumonia, acute middle ear infections, and skin infections.
Biaxin is also used to prevent Mycobacterium avium complex (a number of bacterial infections that are usually associated with HIV infection [AIDS]) disease in people with advanced HIV infection.
Do not use Biaxin if you are pregnant, except in circumstances where no alternative therapy is appropriate as determined by your doctor. Biaxin can cause harm to your unborn baby.
Diarrhea is a common problem when taking antibiotics; it usually ends when the antibiotic is stopped. Sometimes after starting treatment with antibiotics, people may develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. Contact your doctor right away if this occurs.
Biaxin does not treat viral infections such as the common cold.
Take Biaxin as prescribed by your doctor for the full course of treatment, even if your symptoms improve earlier. Do not skip doses. Skipping doses or not completing the full course of Biaxin can decrease its effectiveness and can lead to the growth of bacteria that are resistant to the effects of Biaxin.
Biaxin can cause myasthenia gravis (a disease characterized by long-lasting fatigue and muscle weakness). If you feel weakness in your muscles, tell your doctor immediately.
