i am just starting to take a low dose of topamax at 50mg a day and not going to increase to more than 100mg a day and i am wondering if this will interfere with my lutera pills?? i have read that it lowers the effectiveness but i have also read that it doesnt happen until you reach doses of 200mg or more. i have also heard that by increasing your birth control dose you can help the effectiveness and my doctor specifically prescribed lutera because it has a higher dosage than most BC. can anyone give me some more info because every where i go i seem to be getting different information, even from doctors.
