Valproate is know to cause the side effects that your daughter is experiencing. even though it is expected to get better over time, if the weight gain is significant (>2 kg/month), we should consider other drugs as well. If she has absence seizures, the other drug can be ethosuximide
. If she has GTCS, she can be given phenytoin, carbamazepine
