I've been on topamax for a while and they recently increase the dose from 300 mg to 375 mg and now I'm having side effects again from numbness in the lips and cheeks to the hands, to actually forgeting things that I nornmally wouldnt, and and just todat my manager at mention that I was slurring words when talking to customers and I didn't know I was at the time. Has any one esle had this problem on topamax?
