Rifampicin capsules are used to treat tuberculosis, as it is an essential part of the standard treatment protocols for all types of tuberculosis, whether pulmonary or extrapulmonary. Rifampicin is used to treat other bacterial infections such as meningitis caused by meningococci as a preventive measure for people who have been in close contact with infected people.
Rifampicin is also used to treat infections caused by Staphylococcus aureus and leprosy in conjunction with other drugs to ensure greater effectiveness and prevent the development of bacterial resistance.
