Cause of death

Positional asphyxia caused by the combined effect of consumption of several opiate-containing medications (Oxycodone, Fentanyl, Doxylamine, Promethazine, and possibly Pregabalin) leading to sedation and respiratory depression

AI-generated summary

57-year-old woman with chronic pain died from positional asphyxia caused by consumption of multiple sedative medications. She was prescribed opioids (Fentanyl, Oxycodone) and Pregabalin, but also obtained Dolased and Promethazine (containing codeine and doxylamine) over-the-counter without medical knowledge. These sedating drugs combined caused severe drowsiness and respiratory depression, preventing her from extricating herself from a flexed-neck position against a coffee table. Contributing factors included lack of proactive medication review documenting over-the-counter drug use, poor communication between her GP and pain specialist about medication changes, and patient non-disclosure of OTC medications despite GP advice to use OTC alternatives. The death was preventable had the GP explicitly documented which specific OTC medications were appropriate, and had medication interactions been actively monitored.

Contributing factors

  • Patient consumed over-the-counter medications (Dolased, Promethazine) without medical knowledge or supervision
  • Multiple sedative medications combined causing significant respiratory depression and drowsiness
  • Patient unable to extricate herself from flexed-neck position due to sedation
  • Lack of systematic medication review documenting over-the-counter drug use
  • Inadequate clarification by GP of which specific over-the-counter medications were appropriate when discussing pain management alternatives
  • Increasing use of Dolased in the months prior to death not detected by treating doctors
  • Patient becoming increasingly difficult to rouse from sleep prior to death
  • Delayed and infrequent communication between GP and pain specialist regarding medication changes

Coroner's recommendations

  1. Pain clinic should implement a completed questionnaire about all over-the-counter medications (including recreational drugs, herbs, vitamins and supplements) as part of initial patient assessment
  2. General practitioners should conduct more proactive systematic medication reviews specifically documenting all over-the-counter medications being taken by patients on complex pain regimens
  3. General practitioners should be more specific in discussions about over-the-counter pain medication use, documenting exactly which products are appropriate when advising patients to use OTC alternatives
  4. Improved communication between pain specialists and general practitioners regarding medication changes and patient medication history to ensure consistent and complete medication records
