The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry titled "Evaluation of Therapeutic Equivalence." This guidance explains FDA's thinking on therapeutic equivalence evaluations and therapeutic equivalence codes (TE codes). FDA's therapeutic equivalence evaluations are listed for multisource prescription drug products approved under the Federal Food, Drug, and Cosmetic Act (FD&C Act) in the active section of the "Approved Drug Products With Therapeutic Equivalence Evaluations" (commonly known as the Orange Book). These therapeutic equivalence evaluations have been prepared to serve as public information and advice to state health agencies, prescribers, and pharmacists to promote public education in the area of drug product selection and to foster containment of health care costs. This guidance finalizes the draft guidance of the same title issued in July 2022.
