What is the dosage and how should it be used?
Rifampin (rifampicin) comes as a capsule, suspension, or injection.
Use rifampin exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.
Take the rifampin capsule on an empty stomach 1 hour before or 2 hours after meals. Swallow the capsule with a full glass (8 ounces) of water.
Use the rifampin for as many days as it was prescribed for you, even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated. Please note that rifampin will not treat a viral infection such as the common cold or flu.
Injectable rifampin should only be administered under the supervision of a qualified healthcare provider. Talk to your healthcare provider if you have questions regarding injectable rifampin.
