Rifabutin is an antibacterial prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the prevention of disseminated Mycobacterium avium complex (MAC) disease in people with advanced HIV Infection. Disseminated MAC disease, also called disseminated MAC infection, is an opportunistic infection of HIV. An opportunistic infection is an infection that occurs more frequently or is more severe in people with weakened immune systems -- such as those infected with HIV -- than in people with healthy immune systems.
