The FDA issued a final compliance guidance related to pharmacy compounding. In the guidance, the FDA clarified which activities compounding pharmacies could lawfully engage and which activities the FDA considered unlawful. The owner of the compounding pharmacy directed the staff pharmacists to engage in activities that the FDA considered unlawful. When challenged by a staff pharmacist, the owner replied that those are merely FDA opinions and not legally enforceable. How should the staff pharmacist respond to the owner?
