I have had migraines for years and as I got older the migraines got worse. I was having four a month when my doctor started me on Topamax. I was to take 25 mg at night for a week and then increase each week until I was up to 100mg. I never made it 100mg. At 50mg I woke up with double vision. My doctor said the Topamax was so great for migraines that I stayed at 25 mg for over a year. Thats when the side effects started. I had lost of concentration and inability to find the right words. I thought I was just getting old...even thought I was in early stages of Alzheimer. I had mild depression but thought it was from things I was going through in life. Then I notice that my morning urine would smell. I cant even describe the smell just different and I knew something was wrong. I haven't had a menstrual period in over five years but started spotting. Thats when I looked up the side effects. I stopped taking the Topamax immediately. The smell in my urine went away after a few days off of it. I am hoping that my memory and concentration improve gradually. Its not worth the problems it causes. Now I'm looking for another way to lessen the migraines.
