Autistic child 13 year old and out of control; what medication should I use?

Speak to Physician. It is important you speak to your child's pediatrician about this. Every child with ASD needs a tailored approach to their medication, behavioral therapy and nutritional profile.
Too little info. Much more information is needed. Find a specialist in autism to work with you on understanding what is happening with your child. Are these new behaviors or longstanding? If the former, a physical exam is essential. Behavioarl therapy may be a big help. Medicines can be a real lifesaver too, but which one to choose will depend on understanding what is happening.
