Hello.i have got a 14 boy who was diagnosed sever adhd and conductive disorder.he creates a lot of problems in school , he refuses to use any tablets?

Who has the problem?: You or him? It is fundamental failure of parenting when the child is not given the opportunity to take personal responsibility for his/her actions. If he is not willing to take tablets, then he has to come up with a better solution for his problems. The situation is far deeper than the tablet issue. You need to figure out your role in perpetuating his irresponsible behavior and change yourself.

There's something: Else going on. First, take him to his pediatrician for a complete physical & a random urine drug screen. He may open up to his dr. If alone. Seek referrals to a child & adolescent psychiatrist & a psychologist. If his behaviors are a danger to himself or others, seek an assessment by the admission team at a children's psychiatric hospital. His options are hospitalization or juvenile detention.
