my son is 9yrs. old and was prescribed this same medicine. I haven't given it to him yet . I said I would read up on it first before I gave it to him. I'm scared to give it to him now that I have read up on it. I mean is it safe to take. Why would they prescribe blood pressure meds for anger problems? Will he be o.k ?He plays football and needs all the rest and energy he can get. his dad is pschitzophrenic and he has anger management issues.
