I did a quick google search for articles about ivermectin overdose but all I found was there's been an uptick but it seems overexaggerated. This[0] one shows there were 21 people who called in about ivermectin, it's only one state but still doesn't seem like a big deal. There was another story about a Mississippi hospital[1] where 70% calls were about ivermectin but then it turned out they meant 70% of calls about ivermectin (not total calls) were about the animal version. This article [2] includes Minnesota which saw <100 calls and people having overdose symptoms but no one dying.

Treating covid with ivermectin does seem like a bad idea, but it also doesn't really seem that dangerous overall. I'm sure there are deaths out there from people overdosing on it but they seem like a really rare event.
