Rifampicin 300mg

Rifampicin 300mg — Uses and Benefits

Rifampicin 300mg is primarily used to treat tuberculosis (TB) infections, and is also used in the treatment of leprosy and prevention of meningococcal infections in certain cases.

WHAT THIS MEDICINE IS USED FOR

• Treatment of pulmonary and extrapulmonary tuberculosis
