The LD50 for Ivermectin is 10mg/kg. The standard dosage range is .1-.5mg/kg. (from memory... YMMV) So, you would have to guzzle 20 times the recommended dosage of a foul-tasting elixir to get near a lethal dose. It sticks around in your system for ~4days, so there could be a cumulative effect if you guzzle enough over a few day period. But still, much less dangerous as Tylenol (toxic at 10g dose; typical therapeutic dose on the order of 1g): Paracetamol poisoning was first described in the 1960s.[6] Rates of poisoning vary significantly between regions of the world.[8] In the United States more than 100,000 cases occur a year.[1] In the United Kingdom it is the medication responsible for the greatest number of overdoses.[7] Young children are most commonly affected.[1] In the United States and the United Kingdom, paracetamol is the most common cause of acute liver failure.[9][1] And furthermore, since Ivermectin is a potent antiparasitic, many people are likely to experience Jarisch–Herxheimer reaction to the death of intestinal parasites, which indicates its working, not dangerous. So, take is slow if you also have parasites. But, by all means, carry on believing what you're told to! ;)
