I would ask if there is another med your son can try. There are many out there and every child can show differnt responses to meds. You have to find the one that works best for him. The physical and emotional abuse is not good for anyone. I read a book called the Explosive Child that was helpful to gain a general approach to dealing with it but I found medication is very helpful in addition to counseling. It is difficult because you have to really push to get what you need but you and your children will be netter in the long run for it.
