In January 2018, the U.S. Food & Drug Administration (FDA) published two guidance documents on Compounded Drug Products That Are Essentially Copies Of Approved Drug Products under Section 503A and Section 503B of the Federal Food, Drug, and Cosmetic Act (the Act). As emphasized in a recent U.S. Department of Justice policy memorandum, FDA noted that its guidance documents do not establish legally enforceable responsibilities and, instead should be viewed only as agency recommendations, unless specific regulatory or statutory requirements are cited.
