A member asked:
How long after taking doxycycline does it take for my birth control (blisovi fe) to start working again?
A doctor has provided 1 answer
B.C. stays effective: The current thinking is that except for rifampin, other commonly-used antibiotics (such as nitrofurantoin and many others) do not alter the effectiveness of birth control pills. 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.
