Ivermectin is so safe it is given out to whole communities, as in the Peruvian example in the post above, with stunning results.
Even later stage it seemed to demonstrate tremendous efficacy in Broward County Florida:
"On Thursday, a team of U.S. doctors led by Dr. Jean-Jacques Rajter at the Broward Health Medical Center in Fort Lauderdale, Florida, submitted findings to an institutional review board. According to a medical source familiar with the study, some 250 coronavirus patients were involved in the Broward trial. The results were dramatic, with “statistically significant improvement in mortality,” according to the source.
The blood oxygen level of the first patient treated in early April was 70%, and dropped to just 50% within hours. After receiving the invermectin, the patient stabilized within 24 hours and was discharged from the hospital in one week."
