Rifampicin 450mg

Rifampicin 450mg — Uses and Benefits

Rifampicin 450mg is primarily used to treat tuberculosis (TB) and some other serious bacterial infections, always as part of a doctor-guided treatment plan.

WHAT THIS MEDICINE IS USED FOR

• Treatment of pulmonary and extra-pulmonary tuberculosis, usually combined with other anti-TB medicines
• Treatment of leprosy, as part of multi-drug therapy
• Prevention of meningococcal disease in close contacts of infected persons, as advised by a doctor
• Treatment of certain other bacterial infections when specifically prescribed

HOW IT WORKS

• Rifampicin kills bacteria by blocking an enzyme they need to make RNA
• This stops bacteria from multiplying and growing

WHAT IT IS NOT USED FOR

• It is not a painkiller or fever medicine
• It should not be used alone to treat TB, as this can lead to drug resistance
