Companies must report serious adverse reactions of a Natural Health Product (NHP) to Health Canada. Adverse reactions that could result in death, life-threatening illness, hospitalization or disability must be reported within 15 days of the company becoming aware of it. Any other adverse reaction which is deemed serious enough in the opinion of the company, should also be reported within 15 days via an Adverse Reaction Report form. All reports must include detailed information and be submitted on an official reporting form available on the Government of Canada website.
