... from migranes my entire adult life. When starting on Topamax in July, 2008, I thought the doctor had given me a miracle drug for my migraines! About four months ago, the migraines returned. The dr. tapered me off my 200 mg. dosage, so sudden withdrawal could not be the cause of the itching. After calling the doctor's office, I was told to go to the ER. I can just see that now!!! By the way, I've been off Topamax for one week. I also take 20 mg. Lexapro. Second by the way, it's GREAT to have my mind and memory back!!! And thank the dear Lord, I have NOT had a headache for five days!!! Any comments on the itching, I would appreciate!! Will the itching stop?
