Brand Name: Rifadin, Rifadin IV, Rimactane
Drug Class: Opportunistic Infection and Other Drugs
|
Rifampin, also known as Rifadin or Rimactane, belongs to the class of medicines called antimycobacterials. Antimycobacterials prevent or treat infections caused by a certain type of bacterium, including the bacterium that causes tuberculosis (TB).
| Rifampin is approved by the FDA for use with other medicines to prevent or treat TB. TB is an opportunistic infection that commonly affects people with HIV or AIDS. Rifampin also can be prescribed to prevent infection in people who may have come in contact with TB or meningitis patients.
|
| Rifampin comes in capsule form that is taken by mouth and in powder form to be mixed with sterile water that is given by intravenous infusion into a vein. To make it easier for a child to take oral rifampin, the capsules can be opened and the powder mixed with a small amount of applesauce or jelly. Rifampin may also be made into an oral suspension.
Oral rifampin should be taken on an empty stomach, either 1 hour before or 2 hours after a meal. For a more serious infection, or in people who cannot swallow medicines, rifampin for intravenous infusion can be given by slow injection into a vein by a doctor or nurse.
Rifampin also is available mixed with other anti-TB medicines. It is available combined with isoniazid in a capsule called Rifamate, or combined with isoniazid and pyrazinamide in a tablet called Rifater.
