Veterinarians were literally turning people away because they were attempting to buy actual horse de-wormer. This isn't hyperbole. Some people poisoned themselves.

I mean, it's not hyperbolic, it's literally used to de-worm horses.

"horse dewormer" is a type of medicine you can buy which is intended to be given to horses to deworm them. it's a different product from "people dewormer" (we call it an anti-parasitic in that context) with a different formulation and concentration. So it's not correct to say "literal" here, and just weakens your argument.

I think ivermectin doesn't work, but there's nothing wrong with a doctor prescribing it off label in a COVID context. It is not unsafe enough, generally speaking, to override the judgement of an individual doctor. The legal/regulatory system explicitly permits this, and there are other examples where doing this is likely ethically positive.

For example, there was a big controversey around lucentis and avastin where doctors found they could treat peoople with wet AMD with avastin far more cheaply, but the pharma (which marketed both) wanted people to use the far more expensive drug. Doctors actively precribed avastin instead of lucentis and treated patients (most case reports coming in positive) and then finally a large trial was run that showed it was basically as good as lucentis. Ethically, in retrospect, we say the doctors were acting in a good way (saving patients for less $$ and probably treating people who couldn't afford lucentis). I could imagine the owner of the two drugs running a PR campaign "Doctors: why are you prescribing a cancer drug to eye patients? Do you want to kill them"?

There are horse medicines with aspirin, too. Is aspirin now a horse medicine because it contains a common ingredient? Ivermectin is also literally used by millions of humans in countries all over the globe that have parasite problems, because it's an antiparasitic. My whole photo tour group was given Ivermectin when we went to Africa before covid was even a thing.

> Ivermectin is an FDA approved drug for use in humans to treat a variety of parasitic infections including parasitic worms, hookworm and whipworm. It may also be used as an effective treatment for a wide range of other conditions and as a treatment of onchocerciasis, intestinal strongyloidiasis and onchocerciasis or river blindness.

people are literally buying and taking horse de-wormer, this is well documented... the FDA had to put out multiple statements in an attempt to get people to stop taking animal medications instead of vaccines...

I agree that hyperbolic isn't the right word, but do you really think people who call it horse de-wormer* are really being genuine.

*(Outside the context of literally treating horses)
