Ivermectin not authorized to prevent or treat COVID-19

Do not use ivermectin in an attempt to prevent or treat COVID-19. Human formulations of ivermectin should only be used for specific parasitic worm infections, and only under the supervision of a health provider.

There are growing concerns of the unauthorized use of ivermectin to try to prevent or treat COVID-19.

In a safety alert, Health Canada says there is no evidence that it is safe or effective. In fact, its use can result in vomiting, diarrhea, low blood pressure, allergic reactions, dizziness, seizures, coma, and even death.

While there are designated uses for ivermectin in humans, these are specific to certain parasitic worm infections. In addition, those uses require prescriptions to formulations specific to humans.

Part of the difference in animal-vs-human formulations is that animal drugs are often made with higher concentrations. This accommodates the weight of large animals. Furthermore, many of the inactive ingredients used in animal products aren’t evaluated for use in people.

There are no drug submissions or clinical trial applications for ivermectin use against COVID-19 in Canada.

For prevention of COVID-19, the Government of Canada suggests a multi-faceted approach. This may include wearing masks, physical distancing, maintaining hand hygiene, and avoiding crowded places.
