Description: Use of psychotropic medication to change behavior.
Examples: risperidone (Risperdal), methylphenidate (Ritalin), fluoxetine (Prozac), aripiprazole (Abilify)
Research Summary: For individuals with autism spectrum disorder (ASD) who have persistent, severe tantrums, aggression, or self-injury, there is strong evidence from large, well-designed randomized clinical trials supporting the use of low doses of atypical antipsychotic medications such as risperidone (Risperdal) and aripiprazole (Abilify). These medications often produce major reductions in disruptive behavior (McCracken et al., 2002; Hirsh & Pringsheim, 2016) and may improve overall functioning (McDougle et al., 2005). However, the medications also may cause significant weight gain. Combining rispiridone with parent training on behavioral interventions appears to improve outcomes (Aman et al., 2009). Parent training may be an effective alternative to medication for disruptive behavior in younger children with ASD.
For individuals with autism spectrum disorders who have severe hyperactivity and inattention, there is evidence from a large, well-designed randomized clinical trial that stimulant medications such as methylphenidate (Ritalin) sometimes produce major reductions in hyperactivity (Research Units in Pediatric Psychopharmacology Autism Network, 2005). However, up to 20% of children with ASD experience intolerable side-effects when taking these medications. Other medications that can be effective in reducing hyperactivity in some children with ASD include a selective norepinephrine reuptake inhibitor, atomoxetine (Handen et al., 2015; Harfterkamp et al., 2015), and a selective alpha-2A receptor agonist, guanfacine (Scahill et al., 2015).
Selective serotonin inhibitors (SSRI’s) are sometimes prescribed for individuals with autism spectrum disorders who have severe repetitive behaviors or routines. Examples of SSRI’s are fluoxetine (Prozac), paroxetine (Paxil), and cital (Celexa). However, a large, well-designed study indicated that the SSRI cital had no effect on such behaviors (King et al., 2009). Preliminary studies indicate that medications may be effective in alleviating mood swings (Lewis & Lavoritz, 2005). Additional research is underway to test whether findings from preliminary research can be replicated in large, well-designed studies.
Recommendations: Medications are an effective intervention for some individuals with ASD who exhibit severe aggression, hyperactivity, or other disruptive behavior. Medications also can be useful for reducing hyperactivity in some children with ASD. When medications are used, they should be prescribed and monitored by a qualified physician. Because of the evidence for the effectiveness of medications for some individuals with ASD, professionals and families may wish to obtain additional information about this approach; resources are listed in the references below.
