Can Clarithromycin alter the effectivity of birth control pills?

Dear Ask The Doctor: Will clarithromycin affect my birth control

Dear Abbey:

Clarithromycin has no known serious drug interactions with the more common birth control pills. It will neither intensify or diminish the effectivity of your birth control pill. However, it would have been very helpful to me if you also mentioned the brand or generic name of the birth control pill you are having. I do hope I have answered your question and take care always.
