- All sections of the form should be filled in as completely as possible. Use a separate form for each patient. Up to two suspected health products for a particular adverse reaction may be reported on one form. Attach an additional form if there are more than two suspected health products for the adverse reaction being reported. Additional pages may be attached if more space is required.
- For the "Identifier" box, provide some type of identifier that will allow you, the reporter, to readily locate the case if you are contacted for more information; do not use the patient's name. See the Confidentiality disclaimer at the bottom of this page.
- Any follow-up information for an adverse reaction that has already been reported can be submitted using a new form, indicating that it consists of follow-up information, including, if known, the date of the original report and the Adverse Reaction Number provided in the acknowledgement letter.

Information on Adverse Reaction Reporting
What is an adverse reaction?
An adverse reaction is a harmful and unintended response to a health product. This includes any undesirable patient effect suspected to be associated with health product use. Unintended effect, health product abuse, overdose, interaction (including drug-drug and drug-food interactions) and unusual lack of therapeutic efficacy are all considered to be reportable adverse reactions.
A serious adverse reaction is one that requires in-patient hospitalization or prolongation of existing hospitalization, causes congenital malformation, results in persistent or significant disability or incapacity, is life-threatening or results in death. Adverse reactions that require significant medical intervention to prevent one of these listed outcomes are also considered to be serious.
Which adverse reactions should be reported?
All suspected adverse reactions should be reported, especially those that are:
- unexpected, regardless of their severity, i.e., not consistent with product information or labelling; or
- serious, whether expected or not; or
- reactions to recently marketed health products (on the market for less than five years), regardless of their nature or severity.
Alternative ways to report
You can also report side effects to health products to the Canada Vigilance Program:
The Canada Vigilance Adverse Reaction Reporting Form is also available online at or at the back of the Compendium of Pharmaceuticals and Specialties (CPS).
- Submission of a report does not constitute an admission that medical personnel or the product caused or contributed to the adverse reaction.
- Adverse reaction reports are, for the most part, only suspected associations. A temporal or possible association is sufficient for a report to be made. Reporting of an adverse reaction does not imply a definitive causal link.
- Health professionals and consumers may also report adverse reactions to the market authorization holder (MAH). Indicate on your adverse reaction report sent to Health Canada if a case was also reported to the product's MAH.
