evidence: The FDA’s goal was to advise individuals against taking ivermectin, a medication used to treat parasitic infections in livestock, to treat COVID-19. "Stop it with the #ivermectin," the agency advised on Instagram. "It’s not authorized for treating #COVID." [...] More generally, the lawsuit overlooks the fact that the FDA has no power to discipline doctors for prescribing a medication that the agency has licensed, even when the prescription is for "off-label" use — that is, a purpose for which it has not specifically been approved. That’s the case with ivermectin, which the FDA has approved as a treatment for parasitic diseases, but not for COVID. COVID is not caused by parasites. [...] The appellate judges described the agency’s advisories about invermectin as a COVID treatment as more than "factual statements and information." The online posts, the judges said, "contain syntax that is imperative rather than declaratory (for example ... ‘Stop it with the #ivermectin’)." The title of its consumer advisory, the judges observed, is "Why You Should Not Use Ivermectin" for COVID. (Emphasis in the judges’ ruling.)
