How ineffective does a 50mg dose of topamax (topiramate) make birth control of about 30mcg?

A doctor has provided 1 answer

Unknown: It is unknown however the risk of unplanned pregnancy is high. I would recommend you to use an additional barrier birth control or to look for another medication that would not interact with the effectiveness of your birth control pill.
