What is a Generic Drug?

General Medicare Part D (PDPs and MAPDs) · updated Jun 9, 2025

A Generic Drug, according to the Centers for Medicare and Medicaid (CMS) is defined as:

A prescription drug that has the same active-ingredient formula as a brand-name drug. Generic drugs usually cost less than brand-name drugs. The Food and Drug Administration (FDA) rates these drugs to be as safe and effective as brand-name drugs.
