Why is this medication prescribed?

Rifabutin is an antibiotic medication that is primarily used in the treatment of certain bacterial infections, particularly those associated with Mycobacterium avium complex (MAC) in individuals with advanced HIV infection. MAC is an opportunistic infection that can affect people with weakened immune systems, such as those with HIV/AIDS. Rifabutin is also sometimes used as a prophylactic (preventive) treatment to reduce the risk of MAC infection in individuals with advanced HIV infection.

How should this medicine be used?

As for how Rifabutin should be used, it is important to follow the specific instructions provided by the prescribing healthcare professional. However, here are some general guidelines:

• Dosage: The dosage of Rifabutin can vary based on the specific condition being treated and individual factors. It is important to take the prescribed dose exactly as directed.
• Administration: Rifabutin is typically taken orally, usually with food. This helps enhance its absorption and reduces the risk of gastrointestinal upset.
• Consistency: It is important to take Rifabutin consistently and at the same time each day. This helps maintain a steady level of the medication in the bloodstream.

• Avoid Alcohol: It’s advisable to avoid consuming alcohol while taking Rifabutin, as it may increase the risk of certain side effects.

Never self-prescribe or adjust the dosage without consulting your healthcare professional.
