I was on 100 mg of Trokendi XR and my doctor switched me to lamotrigine, starting at 25 mg twice a day, to titrate up to 200 mg daily over a couple months. I stopped the Trokendi immediately - cold turkey- when I started the lamotrigine. Would this change cause me to have topiramate withdrawal? Even though I am replacing it with another anti-convulsant? (albeit a smaller dose)?
