Variability in Psychotropic Medication Use Among Autistic Young Persons in Australia

Strategic Insights -

Research from Curtin University has found significant variability in the prevalence of psychotropic medication use among young autistic persons worldwide, including in Australia. According to the study, apart from risperidone, which is approved by the Therapeutic Goods Administration to manage challenging behavior, the appropriateness of other psychotropic medications prescribed to young autistic persons warrants scrutiny. The study aimed to gain initial insight into the magnitude, types, and indications of psychotropic medication use in autistic children and adolescents in Western Australia, analyzing de-identified data from 239 autistic children and adolescents.

Key Takeaways:

  • The study found significant variability in the prevalence of psychotropic medication use among young autistic persons worldwide, including in Australia.
  • Only 16.4% of the sample received risperidone, while 27.8% received other psychotropic medications.
  • The most common indications for psychotropic medication use were attention deficit hyperactivity disorder (ADHD), anxiety, and behavioral disturbances.
  • The study highlights the importance of ongoing research to better understand mental health-related medications and inform best practice.
  • The authors recommend scrutinizing the appropriateness of psychotropic medications prescribed to young autistic persons.
  • The study's limitations include a small sample size and the lack of information on medication discontinuation rates.

Statistics:

  • 239 autistic children and adolescents were included in the study.
