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.
