Well, my son has been on this medication every since he was 9 months and he don't have no effects from it,it may be it's for some children but not all kids and the only reason he's taking the medication is because he has asthma and this medication really helps him even with his other medication he takes. So it's probably come from he's also coming up on his age for boys that boys has temper episodes they even last longer than a girl would do the only thing u can do is try to calm him done with a fruit or a lolly pop and see if that would work.
