What the Public Needs to Know About Vanessa's Law

The Protecting Canadians from Unsafe Drugs Act, also known as Vanessa's Law, underpins drug and medical device safety in Canada by strengthening Health Canada's ability to collect information and to take quick and appropriate action when a serious health risk is identified.  

As of December 16, 2019, it became mandatory for hospitals to report serious adverse drug reactions (serious ADRs) and medical device incidents (MDIs) to Health Canada.  

Presentation modules for patients and the public 

Patients for Patient Safety Canada created a presentation module to help patients and the public understand and promote the reporting of serious adverse drug reactions and medical device incidents. You can use this module in your presentations and other information-sharing activities.

The Patients for Patient Safety Canada presentation was adapted from four core modules developed in collaboration with Health Canada.

Numerous alerts were generated regarding the uncontrolled flow, including from Health Canada and the manufacturer. This success story from British Columbia shows how Vanessa’s law can prevent harm.

People have given their lives, or they’ve suffered, and the least we can do for them is to report what happened and allow the analysis to occur so we can prevent it from happening again.” - Maryann Murray 

Maryann Murray's daughter Martha died of an adverse drug reaction at age 22.
