What’s the chemical difference between “veterinarian grade” Ivermectin and “human grade” Ivermectin?
Nothing. It does the same thing.
Ivermectin is ivermectin. The differences are in the regulatory pathways. There may also be some differences in excipients depending on the species the drug is to be used on.
For animals not intended for consumption—horses and pet rabbits for example—there is one pathway. For animals intended for fosod it must be shown the drug either is not in finished meat or that it does not harm people/other animals when consumed (other animals typically are dogs and cats).
We had this issue years ago in fisheries, wherein one researcher dosed fish with tetracycline to mark otoliths for age determination, the put the fish out to sea. The problem was the legality of dosing animals with a drug and releasing them into the wild—it is illegal although tetracycline is both a human and veterinary drug.
“. . . animal drugs are concentrated at levels that can be highly toxic for humans.”
That seems to be the big difference.
Article also says FDA has no data proving ivermectin’s use as as covid treatment. But I would guess that concentration is the problem.
