Why is Strattera a non-formulatory drug?

Strattera (atomoxetine) is considered a non-formulary drug because it is not included on a specific health plan's formulary, which is a list of preferred medications covered by the plan. This can happen for various reasons, including cost considerations, the availability of alternative medications that are more effective or have a better safety profile, or the lack of sufficient clinical evidence to support its use over other options. As a result, patients may need prior authorization or to explore alternative treatments covered by their insurance.
