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.

Coroner's recommendations
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
General practitioners should conduct more proactive systematic medication reviews specifically documenting all over-the-counter medications being taken by patients on complex pain regimens
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
Improved communication between pain specialists and general practitioners regarding medication changes and patient medication history to ensure consistent and complete medication records
