Concerta has been tried in Asperger’s. It is however mainly indicated for Attention Deficit Hyperactivity Disorder. However, whether the drug will suit your son or not, and whether he needs it or not can be decided only by his treating doctor. Hope this helps. Take care!
The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. The advice may not be completely correct for you as the doctor cannot examine you and does not know your complete medical history. Hence this reply to your post should only be considered as a guiding line and you must consult your doctor at the earliest for your medical problem.
