The purpose of this study was to examine the current trends in prescribing antipsychotics to children and adolescents within the Texas Medicaid Program. Total enrollments of children and adolescents, ranging from infants to 19-year-olds, in the Texas Medicaid Program were determined for each calendar year from 1996 to 2000. Prevalence was defined as the number of children and/or adolescents with at least one Medicaid prescription claim for an antipsychotic per 1,000 enrollees. Trends in prevalence were assessed over a 5-year period using annual descriptive analyses. In addition, total expenditures for antipsychotics were evaluated within this population. Over the 5-year period, an additional 12.25 children and adolescents per 1,000 enrollees (+160%) were prescribed antipsychotics. The prevalence of atypical antipsychotics increased by 13.29 per 1,000 enrollees (+494%) over the same period. In children and adolescents above 2 years of age, the prevalence of antipsychotic use increased in all groups. Antipsychotic usage was more common in children and adolescents between the ages of 10 and 14 years compared to other age groups. Male and female antipsychotic prevalence rates increased during the 5-year period. The increase in total expenditures was related to the increased utilization of atypical antipsychotics.
