Adverse Reaction Database
Canada Vigilance Adverse Reaction Online Database
The Canada Vigilance Adverse Reaction Online Database contains information about suspected adverse reactions (also known as side effects) to health products, captured from adverse reaction reports submitted to Health Canada by consumers and health professionals, who submit reports voluntarily, as well as by market authorization holders (manufacturers and distributors), who are required to submit reports according to the 
Food and Drugs Regulations. Information concerning vaccines used for immunization have only been included in the database since January 1, 2011.
Note: The database cannot be used on its own to evaluate a health product's safety profile. It does not provide conclusive information on the safety of health products, and is not a substitute for medical advice. Should you have an issue of medical concern, consult a qualified health professional. For more information: Interpretation of Adverse Reaction Data.
This database includes data from 1965 to 2011-09-30.
