thanks for your answers!
i like this website!
There is definitely conflicting information. I was always told they did interfere.
I say if you don't want to be pg, then use a backup method for sure!
Good luck and good question.
I would say YES that antibiotics interfere with the pill. I know too many people who have gotten pregnant around the time of an illness - not realizing it..
As the first response noted, the latest research has shown that most antibiotics do NOT affect the pill. That said, some women DO get pregnant while on the pill and taking antibiotics - but it's important to realize they would have gotten pregnant anyway. The reason is that the pill is just not 100% effective. When you compare the pregnancy rates of those on antibiotics and those not, there's really no difference.
You will most likely get conflicting answers, but I have posted a blurb from the Mayo Clinic's website. The predominant feeling among the medical community is that most antibiotics are safe to use while on birth control, with the exception of rifampin. If you are concerned, use the "double up" method and wear a condom.
The effects of antibiotics on birth control pills may be overstated
