My six year old boy has had a series of tonic clinic and focal seizures and has been prescribed Keppra to control and prevent the seizures. We are one week in and he his dose has now doubled to 5 ml per day. We have noticed (and so have school) that he is suddenly very hyper (he was already quite hyper but there is a noticeable increase). Has anyone had similar and does the hyper behaviour, shouting etc die down?? If so when?
