Generics Preferred with Express Scripts
The Generics Preferred program is designed to encourage the use of generic drugs instead of brand-name drugs. Typically, brand-name medications are 50% to 75% more expensive than generics.
If you or your doctor chooses the brand-name drug when a generic exists, you must pay the difference in cost between the brand-name drug and the generic drug in addition to your copay. See "Dispense as Written" for more information.
