How do other medications affect my birth control pill?

ANSWER

Some medicines can make your birth control pill less effective. Most antibiotics are safe to take while you’re on birth control pills, but one -- rifampin (Rifadin IV) -- can stop the pill from working. Tell your doctor you’re on birth control if he prescribes you rifampin.

Other medicines like mood stabilizers, epilepsy medicines, and HIV drugs can also make the pill less effective. Make sure to discuss these with your doctor.
