Rifabutin

Rifabutin (rif-a-BUE-tin) is used to help prevent Mycobacterium avium complex (MAC) disease from causing disease throughout the body in patients with advanced human immunodeficiency virus (HIV) infection. MAC is an infection caused by two similar bacteria, Mycobacterium avium and Mycobacterium intracellulare. Mycobacterium avium is more common in patients with HIV infection. MAC also may occur in other patients whose immune system is not working properly. Symptoms of MAC in people with acquired immunodeficiency syndrome (AIDS) include fever, night sweats, chills, weight loss, and weakness. Rifabutin will not work for colds, flu, or most other infections. Rifabutin is available only with your doctor's prescription, in the following dosage form: Oral Capsules (U.S. and Canada)

Rifabutin helps to prevent or slow the spread of Mycobacterium avium complex (MAC) disease in patients with human immunodeficiency virus (HIV) infection. Rifabutin is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Rifabutin comes as a capsule to take by mouth. Rifabutin usually is taken once or twice a day. Take it on an empty stomach, 1 hour before or 2 hours after meals. If you have difficulty swallowing the capsule, you may empty its contents into applesauce. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Rifabutin exactly as directed.
