I am not 'skittish' about trying Ivermectin paste. After all, most all meds out today were tested on animals first and some where developed for animals then put on the market for humans. One example is Pepto-Bismol was developed by a veterinarian for constipation in pigs. I'm not afraid of taking Pepto when I need it. In the last 'crisis' people were buying up fishmox because 'they' threatened antibiotic supply.
