South Korean cancer patients have caused a shortage of an anti-parasitic drug for dogs in the country, after YouTube videos went viral claiming that the treatment cured a United States patient with terminal cancer.

Despite repeated warnings from the government about feared side effects, a growing number of patients have been taking fenbendazole, meant for ridding intestinal bugs in dogs and cats, in a phenomenon that is leaving doctors and health authorities in South Korea shaking their heads in disbelief.
