Prevalence of Psychotropic Medicine Use in Australian Children with Autism Spectrum Disorder: A Drug Utilization Study Based on Children Enrolled in the Longitudinal Study of Australian Children.

Rasmussen et al. (2019) counted how many Australian kids with autism were taking psychotropic meds. They used national insurance claims from 2014. The sample covered children and teens across the country.

One in three autistic children had at least one psychotropic medication claim that year. ADHD medicines and antidepressants topped the list. Antipsychotic use was lower.

Levin et al. (2014) looked at 30 countries and saw huge gaps: rich nations prescribe up to 900 times more meds than poor ones. Lotte’s 33 % rate sits inside that high-income range, so Australia follows the same money-linked pattern.

Schaaf et al. (2015) asked UK parents and found lower med rates than most published numbers. Lotte used hard claims data, not parent memory, so the higher count likely reflects true use, not under-reporting.

Storch et al. (2012) surveyed Williams parents and found SSRIs helpful with mild side effects. Lotte shows these same drugs are common in autism, but leaves open whether benefits and side effects match.

You now have a clear benchmark: expect about one third of autistic clients to be on psychotropic meds. Always ask for a current medication list and the prescribing doctor’s name at intake. Update the list each quarter and loop prescribers into behavior-plan changes. This simple step prevents drug-behavior interactions and keeps treatment teams on the same page.
