I have had migraines for over 25 years. Last year my doc recommended Topamax. For a year i took it and seemed to doing fine, but, BIG BUT, about
5 months after I started taking it, I noticed that my hair was coming out in clumps. I researched whether hair loss was a side effect, but it is not listed as one by the drug company. After a year, and numerous trips to my primary care doc and dermatologist, I went off the Topamex. My hair started to grow back a few months later. Now, a year later, I finally have hair on my head, and not on the shower floor.
