Before taking Mycobutin

if you are allergic to rifapentine or rifampin.

Tell your doctor if you have ever had tuberculosis, if anyone in your household has tuberculosis, or if you have recently traveled to an area where tuberculosis is common.

Relate drugs

How to use Mycobutin

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Mycobutin may be taken with food if it upsets your stomach.

If you develop signs of tuberculosis while taking Mycobutin, you should be treated with tuberculosis medications right away. Taking only this medicine while you have active tuberculosis could make the infection resistant to antibiotics. Call your doctor if you have any signs of tuberculosis: fever, cough, night sweats, loss of appetite, weight loss, and feeling constantly tired.

While using Mycobutin, you may need frequent blood tests and chest x-rays.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Mycobutin will not treat a viral infection such as the flu or a common cold.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

Warnings

You should not use Mycobutin if you have active tuberculosis, or if you are also taking delavirdine or voriconazole.
