Ivermectin is incredibly safe. "Acetaminophen overdose is the leading cause for calls to Poison Control Centers (>100,000/year) and accounts for more than 56,000 emergency room visits, 2,600 hospitalizations, and an estimated 458 deaths due to acute liver failure each year." https://aasldpubs.onlinelibrary.wiley.com/doi/10.1002/hep.20...
"Hepatic adverse events Ivermectin was suspected to be a hepatotoxicant. In fact, this claim reproduced in several publications was based on few individual case reports [Sparsa, 2006; Veit et al., 2006; Hirota et al., 2011] where the causal relationship with ivermectin treatment was not convincingly established. The last update of LiverTox [2018], a database of drug-induced hepatotoxicity, did not classify ivermectin as a known hepatotoxicant, a conclusion recently confirmed by the US National Institutes of Health [NIH, 2021]."

(edit: not 50,000 liver failures, 56,000 er room visits :)
