seizures
"My 19 year old daughter started having gran mal seizures 3 years ago and was started on Keppra. She was started at 500mg/day and is now at 1000mg/day. Since starting, her seizures have been kept about 95% at bay. She still has an occasional mild seizure (2 in the past year), and they haven't been nearly as intense or as long as before starting Keppra. I'm very pleased and I know she is relieved. The only side effect I've noticed is some constipation. I haven't seen any negative changes in her demeanor."
