Summary

  • Rifampin is used to treat bacterial infections like tuberculosis, which is a serious lung infection. It is also used for other infections such as leprosy and to prevent meningitis, which is inflammation of the protective membranes covering the brain and spinal cord, in people exposed to certain bacteria.

  • Rifampin works by inhibiting RNA synthesis, which is the process of making RNA from DNA, in bacteria. This stops the bacteria from multiplying, helping to clear the infection from the body. It is effective against a range of bacteria, making it useful for treating various infections.

  • The usual adult dose of Rifampin is 600 mg once daily. For children, the dose is typically based on body weight. It is taken on an empty stomach, either 1 hour before or 2 hours after a meal, with a full glass of water. Always follow your doctor's specific dosing instructions.

  • Common side effects of Rifampin include nausea, which is a feeling of sickness with an inclination to vomit, vomiting, and loss of appetite. These effects occur in a small percentage of people. If you experience new symptoms, they might be temporary or unrelated to the medication.

  • Rifampin can cause liver problems, so regular liver function tests are recommended. It is contraindicated, which means it should not be used, in people with severe liver disease. It can also cause a harmless reddish-orange discoloration of body fluids. Always inform your doctor about your medical history before starting Rifampin.
