That claim is false.
The largest study in favour of ivermectin as a COVID-19 treatment was retracted after concerns about data fabrication, plagiarism and ethical breaches.
No clinical studies have proven whether ivermectin can slow or stop the novel coronavirus from growing in human cells — but that hasn't stopped right-wing media personalities and politicians from touting it as a possible treatment or cure for COVID-19.
Ivermectin is sold as a treatment for internal parasites and lice.
Lance Olson, manager of Lone Star Tack & Feed Inc., located just outside of Calgary, said false claims circulating about the animal medication have brought the wrong kind of attention to his business.
"It's obviously not intended for human use in any way shape or form. It's meant to get rid of worms in horses' guts … so, these people see that ivermectin liquid, they search it, our website comes up and they give us a call thinking that we can just sell it to them," Olson said.
"If you don't know what it is, you probably don't have animals that you're going to use this on … given the circumstances surrounding this stuff it makes it very uncomfortable when people phone … so we've taken it off our shelves."
