A member asked:

I have been having blood in my discharge for 5 days after taking macrobid, is my birth control pill still effective?

A doctor has provided 1 answer

BC pills should work: The current thinking is that except for rifampin, other commonly-used antibiotics do not alter the effectiveness of birth control pills such as Aviane. This is likely presuming a person is not sick with vomiting or bad diarrhea, or some other condition that decreases the absorption of a swallowed pill.
