Professor at the University of British Columbia says Health Canada must be more consistent with other countries in issuing warnings about the safety risks of some drugs, especially if other countries are already taking the same medicines.
Barbara Mintzes is the lead investigator of a new study and says that between 2007 and 2016 Health Canada issued a security warning for only 50% of drug safety issues found in the United States, Australia, and the United Kingdom.
During this period, she joined researchers in analyzing 1,441 advisors and found that regulators in all four countries were only consistent in deciding to warn their residents of 10% of the time with the same drug.
The UBC affiliate professor also calls on Canada to be more transparent in providing readily available online information on adverse reactions involving various drugs.
Health Canada did not respond immediately to the request for comment.
The study is published in the JAMA Internal Medicine, published by the American Medical Association, and also includes research from York University in Toronto and the University of Sydney in Australia.
