Rifampicin is an antibiotic used to treat tuberculosis and other bacterial infections. It works by inhibiting bacterial RNA polymerase. Common forms include capsules, syrup, ointment, and intravenous powder. Rifampicin must be taken regularly as part of a combination drug regimen to prevent drug resistance and is commonly used with isoniazid, ethambutol, pyrazinamide, and streptomycin to treat tuberculosis. Common side effects include nausea, vomiting, headache, and liver dysfunction. Due to interactions with many other drugs, patients should notify their provider of all medications.
