Rifampin (rye-FAMP-in) is a medicine used to treat tuberculosis (TB) and to kill certain bacteria (germs) that are carried in the nose and throat. People who have some of these germs may not be sick. These people are called carriers. These carriers can infect people who are not able to fight off the infection. This medicine is also used to prevent disease in people who are in close contact with patients infected with certain bacteria or germs. It is important to start this medicine right away.
