Using ethinyl estradiol together with topiramate can alter the effects of ethinyl estradiol. Topiramate can make birth control pills less effective, which may result in pregnancy. Before taking topiramate, tell your doctor if you use birth control pills. If you are using oral contraceptives you should be advised of the risk of breakthrough bleeding and unintended pregnancy during topiramate therapy. Alternative or additional methods of birth control should be considered during topiramate therapy. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
