At least in the US, ivermectin requires a prescription to obtain. This means a medical professional (MD or nurse practitioner) believes it is safe for use with that individual and they are supervising it.
This is a misleading rebuttal. There were countless stories about feed stores running out of stock or having to limit sales because people were buying it for personal use in huge volumes. There was literally a US wide shortage of agricultural ivermectin in August/September, and I’m not sure if it’s gotten any better.
