Part of the problem that there is censorship on publishing in the big journals. That said, there are published RCT showing Ivermectin effectiveness. In my second link on my first comment, there's a talk about the overwhelming data, censorship and hindrances for publishing. Sharing evidence on Ivermectin - Dr. Tess Lawrie https://player.vimeo.com/video/554350476?autoplay=1#t=5756
Effectiveness is not the only criteria that experts need to evaluate for treatments. Ivermectin is fairly easy to overdose on, and people started self-treating prophylactically because it was easy to find from veterinary supply chains. The majority of available Ivermectin also contained inactive ingredients that had no been safety tested on humans, again because of its primary veterinary uses. WHO looked at these fac…
In the talk above, the Ivermectin safety profile is specifically discussed here: [1]
"Ivermectin was generally well tolerated, with no indication of associated CNS toxicity for doses up to 10 times the highest FDA-approved dose of 0.2mg/kg." [2]
The only way you can overdose is if you use horse paste, and get the dose wrong by more than an order of magnitude. Even then, it's unlikely to result in hospitalization or death. The only reason people have to use horse paste is because they are unable to safely obtain Ivermectin by other means.
