There are somewhere around 40 trials of Ivermectin completed so far. About 16 or so are random, controlled trials. Others are observational.
All of them show the Ivermectin works for pretty much all stages of the disease except the very end.
Prophylaxis, post exposure, mild, medium and even helps in severe. It just won't bring people back from death's door.
The NIH updated their guidance on it, allowing your doctor to prescribe it. There are other ways to take it to prevent the disease in the first place. It's a very safe drug. Now if I just find out where to get my horse tail trimmed....
It did bring back someone from deaths door but that may be a rare case. The family of a Buffalo woman had to go to court.
I saw another story about someone sneaking it into the hospital to try to save someone. The story didnt go into how they snuck it in since visitation wasn’t allowed.
