Restrictions on antidepressant medications for children: a review of Medicaid policy.

OBJECTIVE This study evaluated Medicaid's prior-authorization policies restricting the prescribing of antidepressant medications for children. METHODS Medicaid program prior-authorization policies for antidepressant medications were obtained for all available states. All criteria needed for authorization were recorded, with a focus on policies that applied specifically to children. RESULTS Data from 49 states and the District of Columbia revealed that 30 states (60%) required prior authorization for antidepressants, of which eight (27%) made specific provisions for children. These provisions varied across states. In most states fluoxetine could be prescribed for children with minimal restrictions, and two states had prior-authorization policies that strongly encouraged pediatric patients to use fluoxetine. State policies regarding other selective serotonin reuptake inhibitors varied widely. CONCLUSIONS Although relatively few states included provisions for children in prior-authorization requirements for antidepressants, in states that did, the policies implemented varied widely. These findings raise important questions about the rational development of prescription drug reimbursement policy.
