Ivermectin not authorized to prevent or treat COVID-19; may cause serious health problems
Health Canada has received concerning reports of the use of veterinary ivermectin to prevent or treat COVID-19. Canadians should never consume health products intended for animals because of the potential serious health dangers posed by them. In this light, Health Canada is advising Canadians not to use either the veterinary or human drug versions of Ivermectin to prevent or treat COVID-19. There is no evidence that ivermectin in either formulation is safe or effective when used for those purposes.
The human version of ivermectin is authorized for sale in Canada only for the treatment of parasitic worm infections in people. The veterinary version of ivermectin, especially at high doses, can be dangerous for humans and may cause serious health problems such as vomiting, diarrhea, low blood pressure, allergic reactions, dizziness, seizures, coma and even death. Ivermectin products for animals have a higher concentrated dose than ivermectin products for people. The Department is aware of multiple reports of patients in the U.S. who have required medical support and been hospitalized after using ivermectin intended for horses.
Health Canada is closely monitoring all potential therapeutic treatments for COVID-19, including treatments being studied in international clinical trials. To date, Health Canada has not received any drug submission or clinical trial application for ivermectin for the prevention or treatment of COVID-19. For drugs that have the potential to be helpful in treating COVID-19, Health Canada encourages drug manufacturers to conduct clinical trials. This would provide an opportunity for the healthcare community to collect information on the effectiveness of the treatment and its associated risks. Should a manufacturer provide a submission to Health Canada related to the use of ivermectin to prevent or treat COVID-19, Health Canada would conduct a scientific evaluation of the evidence to determine the drug’s quality, safety and effectiveness.
Health Canada will continue to monitor the situation and will take appropriate and timely action should new information become available, including any information regarding the illegal advertising or sale of ivermectin. Health Canada will also communicate any new safety information to healthcare professionals and consumers. Health Canada has previously warned Canadians about products making false and misleading claims to treat or cure COVID-19.
