Have you read the FDA's article? Let me summarize. Thou shalt not use Ivermectin because:
> Ivermectin tablets are approved [...] for some parasitic worms.
> Taking large doses of this drug is dangerous and can cause serious harm.
(Unlike any other drug.)
> There’s a lot of misinformation around, and you may have heard that it’s okay to take large doses of ivermectin.
...while also...
> The FDA has not reviewed data to support use of ivermectin in COVID-19 patients to treat or to prevent COVID-19; however, some initial research is underway. Taking a drug for an unapproved use can be very dangerous. This is true of ivermectin, too.
> Ivermectin Products for Animals Are Different from Ivermectin Products for People
Scientific authority is an oxymoron.
