evidence: The FDA agreed to delete certain social media posts and webpage updates that urged people to stop using ivermectin to treat or prevent Covid-19. The agency agreed to a settlement on Thursday with three Texas doctors who sued the Food and Drug Administration, alleging it provided unlawful medical advice about the off-label use of ivermectin to treat or prevent the disease. The US Court of Appeals for the Fifth Circuit in September 2023 ruled the FDA "has identified no authority allowing it to recommend consumers ‘stop’ taking medicine" or to otherwise give medical advice, in "tweet-sized doses."
