I have uncontrolled seizures for 53 years. I have taken almost every medication possible. I almost died from a rare side effect of a newer drug. My doctor is very understanding about this. She has added zonisamide to the Lamcital and Depakote I take. It has done miracles! What once was 6 or 8 seizures monthly is now 1 a month. Zonisamide (a sulfa drug) for seizures?
