In order to make the most of your prescription drug benefit through Express Scripts, it’s a good idea to use FDA-approved generic drugs whenever possible. If you are taking a brand-name drug that is not on the plan’s preferred drug list (called a “formulary”), ask your doctor if a preferred- brand drug or a generic would be right for you.
Similarly, fill prescriptions through a retail pharmacy in the Express Scripts network, or via home delivery from the Express Scripts PharmacySM. (Filling a greater than a 32 day supply of maintenance prescriptions at a University pharmacy is the same copay as home delivery.) Of course, many local pharmacies offer other low-cost generic programs, so it’s always a good idea to compare prices at all pharmacies to ensure the best price.
