Anyone take Topomax/Topirimate for migraine prevention or seizure? I was put on it for migraines a week ago because its one of the only drugs safe for migraine prevention as we cant take tricyclics, beta blockers, triptans or SSRIs. So my doctor prescribed it. Within a week I had chest pain, doubled heart rate, flashing lights, weakness and a near fainting spell that required my husband to catch me mid fall. I contacted a Brugada expert I talk to. He informed me this particular drug, although not listed on, disturbs the current in the sodium channel and can be problematic with Brugada patients. He is contacting the doctors in Netherlands who maintain the drug database. Anyone else take this?
