Just wondering if you were aware of some of the details about this de-wormer.

It is of course actually called Ivermectin and has been around since 1975.

From Wikipedia, not the ultimate resource, but useful for this discussion.  William Campbell and Satoshi Ōmura won the 2015 Nobel Prize in Physiology or Medicine for its discovery and applications. The medication is on the World Health Organization's List of Essential Medicines, and is approved by the U.S. Food and Drug Administration as an antiparasitic agent. In 2018, ivermectin was the 420th most commonly prescribed medication in the United States, with more than one hundred thousand prescriptions. It is available as a generic medicine.

Maybe it is not all bad.
