Alesse Drug Interactions

Certain antibiotics, Tegretol, and Topamax are some of the medications that can interfere with Alesse. Drug interactions such as these can lead to increased risk of pregnancy and side effects, among other things. Therefore, before taking the birth control pill, it's important to talk with your healthcare provider about the Alesse drug interactions that may apply to you.
