Topamax (topiramate) is a seizure medicine, also called an anticonvulsant. Topiramate is used to treat seizures in adults and children who are at least 2 years old.
Topamax is also used to prevent migraine headaches in adults and teenagers who are at least 12 years old. This medicine will only prevent migraine headaches or reduce the number of attacks. It will not treat a headache that has already begun.
Topamax may also be used for purposes not listed in this medication guide.
Topamax may cause harm to an unborn baby, but having a seizure during pregnancy could harm both the mother and the baby. Tell your doctor right away if you become pregnant while taking Topamax for seizures. Do not start or stop taking this medicine during pregnancy without your doctor’s advice.
Seek emergency medical attention if you have a sudden change in vision or pain around or behind the eyes. These may be early signs of a serious and permanent side effect on your vision. Do not stop using Topamax without first talking to your doctor, even if you feel fine. You may have increased seizures if you stop using Topamax suddenly. You may need to use less and less before you stop the medication completely. Contact your doctor if your seizures get worse or you have them more often while taking this medicine.
