Generics Preferred with Express Scripts
The Generics Preferred program was 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 choose the brand-name drug where a generic exists, you must pay the difference between the brand and generic in addition to your copayment. Express Scripts will always dispense an available generic medication unless otherwise indicated by the prescriber or the member. See "Dispense as Written" for more information.
