A member asked:

I keep hearing different things regarding antibiotics & bc pills. does metronidazole 500 mg affect it?

A doctor has provided 1 answer

No: The risk is insignificant as long as you are taking your birth control pills exactly as prescribed. This is my opinion based on a lot of years in practice and the lack of any convincing evidence of significant risk.
