Epoh - I am sorry you and your son are going through this.

I want to echo the concern about Risperdal. If your son is not in danger right now to himself or to others, I would really take more time to assess if it is the right decision to put him on a powerful antipsychotic. For me the use of antipsychotics is a much more serious decision than a trial of ADHD meds. These are drugs more often used for schizophrenia and children who are extremely violent and acting out.

Have they done an evaluation and given him a diagnosis?
