Keppra and generalized epilepsy

My six year old daughter was given this medication for idiopathic generalized epilepsy. As soon as she started on this drug we noticed a complete personality change. She was a completely different person. She seemed to be possessed while on this medication. My daughter is a sweet little girl, and is very good for the most part, but when she started this medication it turned her into a monster. She was on this medication for about 2 months, and was taken off it when we got a second opinion. She has not been on any medications while we explore additional opinions for her condition (which is very unusual - she does not have seizures like most people do). I would not recommend this medication to anyone.
