so i've been on a seizure medicine since i was 16, and i've always had to have the real drug and not the generic, well good thing i checked my medicine bottle to note it had been changed to generic. And at the pharmacy it was on file that I don't get generic. But am fortunate that there isn't a lot of difference in the generic to this. So, always be your own advocate with your medicine, your medical files etc. After all it's your body.
