This paper aims to determine the prevalence, patterns, and demographic and diagnostic correlates of psychotropic medication use in a sample of youth in one state's post-adjudicatory secure facilities. The health records database of the facilities was the source of linked demographic, diagnostic and pharmacy information for the 1-year period ending June 30, 2008. Age, gender, race, offense, prior petitions and diagnoses were examined across groups, and concomitant psychotropic pharmacotherapy patterns were identified. Period prevalence was 10.2% for youth ranging in age from 12 through 22 years who had any psychotropic drug prescribed during the first 30 days after intake to the facility. Among medicated youths, almost half received concomitant therapy. Medicated youth were significantly less likely to be Hispanic and more likely to endorse one or more diagnoses. Antidepressants, antipsychotics and antihistamines were the most commonly dispensed agents. Our findings revealed that the rate of psychotropic medication use was low, concomitant medication use was common, and ethnic/race differences in psychopharmacologic treatment were present in this sample of youths in post-adjudicatory secure facilities.
