How many dead in the US because of the suppression of ivermectin?
We don't know. Some number positive or negative.
The evidence for efficacy is neutral, and in that case without a large RCT we do not know: random drugs (look at HCQ) can increase or decrease mortality.
Likely negative because ivermectin was popularised - leading to idiots self-dosing, and many self-overdosing.
Ivermectin is very safe, but safety of ivermectin when you have a COVID infection is an entirely other thing - both have significant affects on the immune system. And you can OD even on very safe drugs.
The final effect that means "likely negative" is that (again idiots) would dose on ivermectin and think themselves safe, so not get vaccinated. That means they are in fact a lot less safe than if they had got vaccinated.
The evidence put forward here for ivermectin is either just scientifically wrong (from fanatics like Tess Laurie who believe they know more than anyone else so their views cannot be questions) of based on a conspiracy meme where there are many people in positions of power who want to kill others. I personally feel these conspiracy memes are part-projection - to go for them you need to ahve unconscious (Freudian?) voilent urges towards mass murder which are suppressed, of course, but lead you to feel that otehrs are quite likley to do that.
Sure, there are mass murderers around - look at Putin, and W* here on this site - but not many - and not typically doctors or scientists. There are always the exceptions that prove the rule. However "suppression of ivermectin" if it happened would need to involve most sceintists and doctors, not juts a few.

* Advocating strongly and irrationally views that cause people to die is technically not murder - so I will of course retract this statement. Replace murder by manslaughter since W is capable of understanding the science but carelessly does not do this.
