Anon, the links you provided say nothing about autism or aspergers. There are no drugs for the treatment of autism. There are however drugs that may be used to control irritability and other unpleasant behaviours... and yes definitely stay away from them.
Schizophrenia is an Autism Spectrum Disorder. There definitely are drugs being given to people
with Autism Spectrum Disorder. I have first hand experience with this, a relative of mine.
If you could be more specific. I could give you more information. Drugs are being given for all
kinds of things, even Social Anxiety Disorder (such as stage fright when you give a speech).
Aspergers does not get as much attention as Autism Spectrum Disorder, but I guarantee you
that it only takes about 5 minutes of talking to a psychiatrist to get a prescription for some
tranquilizer or anti-psychotic or bipolar medication.
I have first hand experience with this also.
