^^ I agree with Cassandra especially about penicillin based ones, but be safe with all antibiotics and BCP by using condoms during the time your taking antibiotics as well as up to1-2 weeks after you stop taking them. :)

better safe than sorry.

This might help!

Women have been hearing stories for years about how taking penicillin or other antibiotics can interfere with the effectiveness of birth control pills. However, according to the Mayo Clinic, a leading healthcare facility, no large, long-range studies have proven antibiotics to cause major interference with the pill. Only one antibiotic, rifampin, has shown to definitively cause loss of effectiveness.

Of course, a small percentage of women may experience decreased effectiveness with the use of other antibiotics, so doctors usually advise all women to use a condom or other backup method of birth control while on antibiotics. There is no way of knowing if you are in that percentage until it is too late. New versions of the birth control pill in low-dose form may be more prone to decreased effectiveness.

Antibiotics are thought to interfere with the metabolization of birth control pills. Birth control pills are usually given a 95 to 99 percent effectiveness rate. The studies that have been done show a very small difference in effectiveness. Usually the difference is less than 1 percent.

A partner taking antibiotics will not interfere with a woman’s use of birth control pills.

There are a lot of antibiotics out there, I would ask a pharmacist or your dr if the specific one you are on can affect birth control, but to be on the safe side use a condom too.
