Rifampin (Rifadin) Medicare Coverage

Rifampin is an antibiotic used to treat asymptomatic carriers of the bacteria that causes meningitis, in order to eliminate the infection before it causes serious harm. It is also used to treat tuberculosis.

Rifampin stops bacteria from forming, which helps stop the infection from spreading and allows the infection to heal. Rifampin is typically taken 1-2 times daily.

The brand name equivalent of Rifampin is called Rifadin.

Common side effects of rifampin include diarrhea, fatigue, gas, headache, upset stomach, heartburn and cramps.
