https://www.fda.gov/consumers/consumer-updates/why-you-should-not-use-ivermectin-treat-or-prevent-covid-19What is Ivermectin and How is it Used?
Ivermectin tablets are approved by the FDA to treat people with intestinal strongyloidiasis and onchocerciasis, two conditions caused by parasitic worms. In addition, some topical (on the skin) forms of ivermectin are approved to treat external parasites like head lice and for skin conditions such as rosacea. Some forms of ivermectin are used in animals to prevent heartworm disease and certain internal and external parasites. It’s important to note that these products are different from the ones for people, and safe when used as prescribed for animals, only.
Ivermectin Products for Animals Are Different from Ivermectin Products for People
For one thing, animal drugs are often highly concentrated because they are used for large animals like horses and cows, which can weigh a lot more than we do—a ton or more. Such high doses can be highly toxic in humans.
Moreover, FDA reviews drugs not just for safety and effectiveness of the active ingredients, but also for the inactive ingredients. Many inactive ingredients found in animal products aren’t evaluated for use in people. Or they are included in much greater quantity than those used in people. In some cases, we don’t know how those inactive ingredients will affect how ivermectin is absorbed in the human body.
