My 12 yr old, 5 9, 113 lbs; diagnosed with ADHD, Anxiety and Autism PDD, NOS he is on Concerta, 54mg (am) and Respiridone .5mg (am) and he takes 1 MG at night. He possibly had an increase on Respiridone by .5 due to Dad and I are divorced and miss communicated it. Since the prescription renewal his behavior is aggressive and he is defiance has increased. Is there anyway to know if the 2 meds counter act each other?
