I think you're confusing this and Ivermectin. Hydroxychloroquine (as far as I know) is prescription only. Ivermectin is too technically but you can get the "livestock" version at a TSC or similar store. Which says a lot about the "not sheep" crowd taking medicine literally used for livestock.
Maybe you should think twice before posting this kind of uncompassionate drivel.
Some of these people died because they trusted the prescription from their doctor. Not everybody is able to read and understand scientific literature, and they might have to rely on the authority of someone they trust. Some doctors believed, against all evidence, that this was the right thing to prescribe and some patients took their word for it.
