National Preferred Formulary (NPF)

A formulary is a list of the medicines covered by your health plan. The Express Scripts National Preferred Formulary is the list of medicines we recommend to treat various conditions. Some plans use our NPF, while other plans modify the list of medicines they cover.

Express Scripts revises its NPF every year, based on reviews of research about the medical value of medicines and their costs. The process of reviewing the NPF and making yearly updates is designed to give members access to the most effective medicines at the lowest possible prices. Your doctor always makes the final decision about the best medicine for you.
