Medication use was examined in 286 adolescents and adults with ASD over a 4.5 year period. A total of 70% were taking a psychotropic or non-psychotropic medication at the beginning of the study. Both the number of psychotropic and non-psychotropic medications taken, and the proportion of individuals taking these medications, increased significantly over the study period, with 81% taking at least one medication 4.5 years later. Our findings suggested a high likelihood of staying medicated over time. Thus, adolescents and adults with ASD are a highly and increasingly medicated population.
KeywordsASD; medication; psychotropic medication; non-psychotropic medication Individuals with autism spectrum disorders (ASD) have persistent impairments across the life course and therefore have an ongoing need for services and treatment, often including medications (Aman, Lam, Van Bourgondien, 2005;Martin, Scahill, Klin & Volkmar, 1999). Only one medication, risperidone, has been approved by the Food and Drug Administration specifically for use among individuals with ASD who have serious behavior problems (Scahill, Koenig, Carroll & Pachler, 2007) and there are few clinical studies addressing the effectiveness of medications in this population (Matson & Dempsey, 2008). There is a limited, but growing, body of research on psychotropic medications used by individuals with ASD. Traditionally, most trials in the population have been open label (Matson & Dempsey, 2008), although controlled trials are becoming more common (Myers, 2007). Whereas advances have been made in pharmacological management of children with ASD (RUPP, 2002(RUPP, , 2005, less is known about medication treatment for adolescents and adults with this diagnosis (Broadstock, Doughty & Eggleston, 2007). Similarly, although there are several studies of medication prevalence in children and adolescents with ASD (Aman, Lam & Collier-Crespin, 2003;Aman, Van Bourgondien, Wolford & Sarphare, 1995;Langworthy-Lam, Aman & Van Bourgondien, 2002;Witwer & Lecavalier, 2005), less is known about the prevalence of medication during adolescence and especially adulthood in this population, which is the focus of the present study.Correspondence concerning this article should be addressed to Anna J.

NIH-PA Author ManuscriptThe prevalence of prescription medications for children with ASD is high. Surveys indicate that one-half to two-thirds are prescribed at least one medication of any type, and about 45% are prescribed at least one psychotropic medication (Aman et al., 2005;Witwer & Lecavalier, 2005). The most commonly prescribed psychotropic medications are antidepressants, stimulants, and antipsychotics (Langworthy-Lam et al., 2002;Martin et al., 1999). However, non-psychotropic medications are also prescribed at high rates for individuals with ASD, although few studies have been conducted to benchmark the prevalence of medic...
