Drugs that affect BC: Azithromycin is a medication that is known to reduce the estrogen in birth control pills and can increase your risk of getting pregnant. BC pills interact with nearly 400 medications so it is important to tell your doctor that you are taking BC pills before he prescribes you any medication. Good luck :)
