Rifampin for TB
Available by prescription only, rifampin (Rifadin®) is a type of antibiotic approved to treat tuberculosis (TB). Rifampin is also licensed to help get rid of Neisseria meningitides, the bacteria that causes meningococcal infections, such as meningitis, in people who have this bacteria in their nose and throat but do not have symptoms of a meningococcal infection.
As a rifamycin antibiotic, rifampin works to kill certain bacteria by blocking the action of an enzyme the bacteria need to survive. When used for TB treatment, rifampin can help treat all forms of tuberculosis. In fact, this drug is the most commonly used treatment for TB.
During treatment, most people with TB will be treated with a combination of medications for at least six months. For the first two months, rifampin is often combined with two or three other medications. After these two months, treatment with rifampin is continued for at least four more months.
