What do rifampin capsules do?
RIFAMPIN (Rifadin(R) or Rimactane(R)) is an antibacterial agent. It is effective as a treatment or a preventative against certain types of bacteria. Rifampin treats all forms of tuberculosis. For this purpose it is never used alone, but in combination with at least one other agent that treats tuberculosis. Rifampin also treats carriers of meningitis and for this purpose it is given alone. Generic rifampin capsules are available.
What should my health care professional know before I take rifampin?
They need to know if you have any of these conditions:
• an alcohol problem
• dental disease
• liver disease
• wear contact lens
• an unusual or allergic reaction to rifampin, rifamycin, other medicines, foods, dyes or preservatives
• pregnant or trying to get pregnant
How should I take this medicine?
Take rifampin capsules by mouth. Follow the directions on the prescription label. Swallow capsules whole with a full glass of water. It is best to take rifampin on an empty stomach; 1 to 2 hours before food, or at least 2 hours after food. If rifampin upsets your stomach you can take it with food. Opening the capsule and mixing the contents with food, such as applesauce, is an easy way to give to children. Take your doses at regular intervals and try not to miss any doses. Do not take your medicine more often than directed. Finish the full course prescribed by your prescriber or health care professional even if you think your condition is better. Do not stop taking except on your prescriber's advice.
What if I miss a dose?
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

• beta blockers, often used for high blood pressure or heart problems
• female hormones, including contraceptive or birth control pills

• itraconazole or ketoconazole
