We have a 12 year old son who has ADHD who is currently on 20 mg Quillichew chewables. It wears off after 4 hours and he is unable to focus at school after that. Not able to sit in class, unable to do in class school assignments or even do PE exercises, etc. Does anyone has any information on booster pills he can take at school to be able to focus.
