A member asked:

I took my last azithromycin on fri which was during the non-active pill week. i started my new pack on sun. will this affect the effectiveness of bc?

A doctor has provided 1 answer

No, unless Rifampin: Other antibiotics are felt not to affect BC pills. A woman who takes birth control pills correctly, and is beyond her first pack of pills, has contraception (protection against pregnancy) every day. That means she can have sex every day and not get pregnant. If she has vomiting or diarrhea bad enough to affect her ability to digest (absorb) her BC pill hormones, then her protection level drops.
