Treatment of Young People With Antipsychotic Medications in the United States – Despite concerns about rising treatment of young people with antipsychotic medications, little is known about trends and patterns of their use in the United States. A retrospective descriptive analysis of antipsychotic prescriptions among patients aged 1 to 24 years was performed with data from calendar years 2006 (n = 765 829), 2008 (n = 858 216), and 2010 (n = 851 874), including a subset from calendar year 2009 with service claims data (n = 53 896). Data were retrieved from the IMS LifeLink LRx Longitudinal Prescription database, which includes approximately 60% of all retail pharmacies in the United States. Denominators were adjusted to generalize estimates to the US population.
