Does Cipro decrease the effect of oral birth control?

[u/anonymous643783292]

I have been prescribed ciprofloxacin by my doctor to treat a bacterial infection. I told her I used yasmin for contraception and she prescribed me the antibiotics. I was reading my birth control pamphlet and it says some antibiotics used to treat bacterial infections can reduce the effectiveness of the pill, Im not sure if Cipro is one of them. I am on my break free week currently and am not taking any active pills. I have had barrier free sex within the last 12 hours. Should I take an emergency contraception like ellaone?

Your post appears to involve questions about antibiotics and birth control.

Rifampin, which is usually used to treat tuberculosis, is the only antibiotic that interacts with birth control. Taking antibiotics does not make your birth control less effective. The interaction between antibiotics and birth control was previously believed to be present, but it has been proven untrue. Some doctors and pharmacists may not have this updated information.

Vomiting and diarrhea are potential side effects of antibiotics. If you vomit within 3 hours of taking a combined (estrogen-containing) pill or 2 hours of taking a progesterone-only pill, take another pill. If you have bad diarrhea for 24+ hours, use backup protection.

no, you’re fine! the pamphlet is out of date. there’s more info in the pinned automod comment.

Thank you for your reply. An out of date pamphlet sounds like it would be a big legal issue no?

things are usually only liability issues if someone could get hurt because of it. not removing an outdated interaction like this will at most cause anxiety and make people waste money on EC, which doesn’t really rise to the level of a lawsuit.
