This comes from the Autism Society of America about medications used for autism, hope it helps. They also have info about other treatment options.http://www.autism-society.org/site/PageServer?pagename=life_treat_medsThere are a number of medications frequently used for individuals with autism to address certain behaviors or symptoms. Some have studies to support their use, while others do not. Serotonin re-uptake inhibitors have been effective in treating depression, obsessive-compulsive behaviors and anxiety that present in some individuals with ASD. Researchers who have consistently found elevated levels of serotonin in the bloodstream of one-third of individuals with autism feel that these drugs could potentially reverse some of the symptoms of serotonin dysregulation in autism. Three drugs that have been studied are clomipramine (Anafranil), fluvoxamine (Luvox) and fluoxetine (Prozac). Studies have shown that they may reduce the frequency and intensity of repetitive behaviors, and may decrease irritability, tantrums and aggressive behavior. Some children have also shown improvements in eye contact and responsiveness.Other drugs, such as Elavil, Wellbutrin, Valium, Ativan and Xanax have not been studied as much but may have a role in treating behavioral symptoms. However, all these drugs have potential side effects, which should be discussed with qualified professionals before treatment is started.Anti-psychotic medications have been the most widely studied of the psychopharmacologic agents in autism over the past 35 years. Originally developed for treating schizophrenia, these drugs have been found to decrease hyperactivity, stereotypical behaviors, withdrawal and aggression in individuals with autism. Four that have been approved by the FDA are clozapine (Clozaril), risperidone (Risperdal), olanzapine (Zyprexa) and quetiapine (Seroquel). Only risperidone has been investigated in a controlled study of adults with autism and was approved in 2006 by the FDA for the treatment of autism. Like the antidepressants, these drugs all have potential side effects, including sedation, which need to be carefully monitored by a qualified professional with experience in autism.Stimulants, such as Ritalin, Adderall and Dexedrine, used to treat hyperactivity in children with ADHD, have also been prescribed for children with ASD. Although few studies have been done, anecdotal evidence shows these medications may increase focus and decrease impulsivity and hyperactivity in autism, particularly in children who are not as severely affected as others. However, dosages need to be carefully monitored because behavioral side effects are often dose-related.
