Hello there,
A complete history about his seizures and medical examination are very important in determining the accurate cause
of your son’s problems. The common
side effects of Keppra XR are sleepiness, dizziness, weakness etc.Very rarely few people may experience aggression, agitation, anxiety on this drug. There may be problems with muscle coordination while on this drug. Your son seems to be in a very difficult situation. I will advise you to consult his neurologist.
