When I went in for my re-fill for Topamax for migraines and Trigiminal Neuralgia I was told that it was now in generic which I new. I also new that the generic was 50.00 which is what I was paying for the regular topamax. I was forced to get generic or pay 100.00. I started taking it Tuesday and on Friday got up in a fog with my left eye hurting followed by by neck then a full force migrained by Saturday. It is Sunday and I still have it. Nothing has helped.
