Hi, our 9 yr old son was on Aptensio 50 mg for several months and seemed like he was having a hard time focusing in class. His Dr. changed the meds to 60 mg which he has been on for 10 days. He is very hyper at this point and all the teachers are complaining. He hates homework and school and seems to be mad a lot. He has been a happy little boy most of the time. Any advice?
