How Covid Misinformation Created a Run on Ivermectin

For months, the veterinary center in West Point, Miss., had watched its supplies of the drug dwindle. Dr. Karen Emerson, the veterinarian who owns the hospital, started the year with one 500-milliliter bottle of ivermectin, which she uses to kill parasites in dogs, chickens and other patients. But as the bottle emptied and her staff tried to find more, they were able to obtain only a 50-milliliter vial. Everyone else told them: None available. So Dr. Emerson began rationing the medicine to give to snakes and other exotic animals for which she had no other deworming treatment. She told dog owners to pay for a more available replacement drug that can cost seven times as much.
