Notification of investigation: potential under-recognised risk of harm from the use of propranolol

  • Written by: Communications team

The investigation will focus on awareness of the toxicity of propranolol, the speed of ambulance response to overdose calls, and the treatment of patients who have overdosed.


Any person, group or organisation can share cases for potential investigation via the safety awareness form. Each submission is reviewed against our criteria, and an important part of assessment is whether we can learn something new that improves practice across the health system. We use a range of approaches focusing on establishing cause and identifying risk.
