seizure prevention
"I've been on this medication for 3 years now for my seizures (50mg/2 daily) and have not had any episodes since.  At first I would get a tingling feeling in my fingers and toes (like soda fizz), but it went away once my body was used to the drug.  Recently, my pharmacy switched me to the generic version and I hated it. Immediately that first day, I would get crazy headaches, feel dizzy, sick to my stomach and I couldn't concentrate on anything. I went back to my neurologist and got a new prescription for brand name only and have not had any problems since. I was also still using the drug during my recent pregnancy and am happy to report no problems or side effects what-so-ever."
