Levetiracetam
"My 4 yr old son started having seizures a few months ago. All the tests have been run and still they cannot find out what is causing them. They diagnosed him with epilepsy and started him on liquid Levetiracetam (Keppra).  Side effects were hyper-ness, not-focused, anger, rage, frustration, hard to fall asleep at night, out of control.  His UCLA Pediatric Neurologist prescribed him Lamotrigine (Lamictal) starting with a really low dose and increasing every week.  So far with decreasing the Keppra I can see a difference, and so can his teachers at pre-school.  This month January 2010 he has only had 2 grand-mals and a bunch of petit-mals. So far no side effects from the Lamotrigine. It's a day by day process."
