Drug regulatory agencies such as the US FDA often issue safety warnings to let health professionals and the public know  about new evidence of potential harm and often to provide advice on how to avoid this.

We were interested to know how consistent these warnings are between different countries. This is a research project funded by Australia’s National Health and Medical Research Council and the Canadian Institutes of Health Research. We examined warnings for medicines in Australia, Canada the US and the UK over a 10-year period, from 2007 to 2016 inclusive. We were looking at how often regulators issue the same warning if the drug is approved for marketing at the time.  Continue reading
