Ivermectin, is very well tolerated and is used for more than "de-worming":
IVM has been used safely in 3.7 billion doses worldwide since 1987 [2,3] and is well tolerated even at much greater doses than the standard single dose of 200 µg/kg [34,35]. It has been used in RCTs for COVID-19 treatment at cumulative doses of 1500 µg/kg [36], 1600 µg/kg [22] and 3000 µg/kg [37] over 4 or 5 days with only small percentages of mild or transient adverse effects.
And yes, of those 3.7 billion doses taken, some people have died. There is little in life that is 100% free from risk.
Some people have also died from consuming too much drinking water as well. Hyponatremia. Because some people have died from drinking water is not a reason to believe water is bad for you.
