Background: Psychotropic concomitant medication use for the treatment of youth with emotional and behavioral disorders has grown significantly in the U.S. over the past 25 years. The use of pharmacy claims to analyze these trends requires the following: age of the selected population, overlapping days of use, and precision of the outcome itself. Th...

Importance
Antidepressants are one of the most commonly prescribed classes of psychotropic medications among US youths. For adults, there is emerging evidence on the increased risk of type 2 diabetes in association with antidepressant use. However, little is known about the antidepressant treatment–emergent risk of type 2 diabetes among youths.
Ob...
Background:

Background. Anticonvulsant (ATC) use for psychiatric disorders in youth dramatically increased during the last decade. This off-label use, particularly by divalproex, is a growing concern because of its doubtful efficacy (Pavuluri MN et al. 2010; Wagner KD, et al. 2006) and safety concerns (Bryant AE, et al. 1996; Wisner et al. 2011). Objectives. T...
