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.
