My son is going off Topamax and onto Zonegran....doctor is slowly removing the Topomax,he was taking 300mg daily. She had me reduce it by 50 mg a week. The Topomax did not control Tripp's seizures and his feet and hands were so "itchy". You need to check with your doctor as how he or she wants to remove it. Our neuro warned us about vision problems but once you remove the Topamax your vision will be restored.If you have seizure and are going off his meds unless another is added you can have more seizures.
