I am scheduled to have my wisdom teeth taken out on Friday. There is a chance I'll be prescribed antibiotics (not sure what kind) to help with pain after the surgery.

I'm currently taking Nordette and this week I'm taking the placebo pills. My question is will taking antibiotics during the placebo week effect my birth control schedule (ie since I'm not taking active pills there's nothing for the antibiotics to react with an lessen the effects of) assuming that I stop taking antibiotics prior to starting my new pack of pills on Sunday? How long are antibiotics in your system and able to effect birth control pills?

Thanks for any answers!

I'd use a condom or spermicide for about a week after the antibiotics.


I got pregnant while taking Ortho Tri-Cyclen and taking Macrobid for a UTI. I ended up miscarrying at 8 weeks (I was still taking the friggin pill.) My doctor said that when a woman gets pregnant on the pill, they were always taking Ortho Tri-Cyclen (based on what she's seen.)

I'm now on Nordette and for some reason only get my period every other month. I need to go back and see what's up with that.
