FDA pregnancy category D. Do not start or stop taking topiramate during pregnancy without your doctor's advice.

There may be other seizure medications that can be more safely used during pregnancy. Follow your doctor's instructions about taking this medicine while you are pregnant.
Topiramate can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking topiramate. If you are not planning a pregnancy while taking topiramate, use effective birth control, and tell your doctor if you become pregnant during treatment.
