evidence: In August 2021, to discourage people from using ivermectin to prevent or treat Covid-19, the FDA tweeted "You are not a horse. You are not a cow. Serious y’all. Stop It." and posted a similar message on Instagram. The tweet got nearly 106,000 likes. [...] "FDA has not changed its position that currently available clinical trial data do not demonstrate that ivermectin is effective against COVID-19. The agency has not authorized or approved ivermectin for use in preventing or treating COVID-19." [...] Bowden, for example, began recommending ivermectin to treat Covid in early 2020 and, according to the suit, was "derided by Houston Methodist Hospital and forced to resign her privileges there as a result." Marik was forced to resign his positions at Eastern Virginia Medical School and Sentara Norfolk General Hospital for promoting the use of ivermectin after the FDA’s actions, according to the lawsuit.
