Is it really possible to get pregnant on the pill when taking an antibiotic?

I have heard in the past that taking an antibiotic will counteract the birth control pill and was wondering if anyone has gotten pregnant this way. I've also heard that this is only true with one type of antibiotic. Anyways, I have been taking Biaxin for 9 days now and am kinda worried that I may have gotten pregnant. My Dr. knows that I am on the pill and didn't mention anything about it. So I'm not sure if I'm worrying for nothing.

  • Well, its really possible to get pregnant while on birthcontrol with no antibiotics, so why not?

    This site however, says that it is unlikely.

  • Depends on the antibiotic, but yes, some do lower the effectiveness of bc pills. I'm sure your dr would have said something if that was the case, but you may want to call your pharmacist just to see. (of course, it may be a little late now lol)

  • It happened to my sister, though I'm not 100% convinced she was taking her BC properly either.
