To expand on Bastethotep’s post, a very early study done on cell cultures before the pandemic went global did show ivermectin having a significant effect on certain viruses, including covid-19. However, it was noted that the dosage used in that trial was well above fatal levels. In actual human trials, at safe doses, there was no notable effect. It’s a case of the dose making the poison, and the level which kills viruses also kills nearly everything else.
Honestly, sometimes I think we should stop publishing “interesting results” which don’t necessarily mean what they might suggest, because stupid people are going to misinterpret things badly. Not that it will completely stop this from happening, but at least it’s easier to point out how idiotic they’re being when they eat garbage-dump dirt or drink pee, and they’ll have a harder time convincing people who are less stupid but desperate.
