Adverse reactions to health products should be reported to Health Canada.
Anyone – including pharmacists, pharmacy technicians, other health professionals, and patients – can report an adverse reaction to drugs and other health products on the Canadian market.
This includes reactions to
- drugs,
- medical devices,
- vaccines,
- natural health products,
- cannabis, or
- veterinary drugs.
How to report an adverse reaction
There are three easy ways to report an adverse reaction to the Canada Vigilance Program:
- by calling toll-free at 1-866-234-2345,
- online at MedEffect Canada website, or
- by completing a form which you can send by postage paid mail.
The form and postage paid label are available at on the MedEffect Canada website or by calling 1-866-234-2345.
What to report
You do not have to be certain that a health product caused the reaction to report it. Adverse reaction reports are, for the most part, only suspected associations. Health Canada wants to know about all suspected adverse reactions, but especially if they are
- unexpected (not consistent with product information or labelling), regardless of their severity;
- serious, whether expected or not; or
- related to a health product that has been on the market less than five years.
When to report an adverse reaction
You should report an adverse reaction soon after the reaction occurred, even if you are not certain that a particular health product was the cause.
Why report an adverse reaction
All marketed drugs and health products have benefits and risks. Although health products are carefully tested before they are licensed in Canada, some adverse reactions may become evident only after a product is in use by the general population.
When you submit a suspected adverse reaction report, you contribute to the ongoing collection of information that occurs once health products are on the market.
Your report may contribute to
- the identification of previously unrecognized, rare, or serious adverse reactions;
- changes in product safety information, or other regulatory actions such as the withdrawal of a product from the Canadian market;
- international data regarding benefits, risks or effectiveness of drugs and other health products; and
- health product safety that benefits all Canadians.
