mixed drug toxicity

AI-generated summary

A 54-year-old nurse with chronic pain from a 1990 back injury died from mixed drug toxicity involving morphine, codeine, doxylamine and nitrazepam. She was prescribed multiple CNS depressants for years despite being designed for short-term use only. Investigation revealed 112 breaches of the Poisons Act 1971 by her GP since 2009, including 20 breaches involving excessive and early morphine supply and 14 where the prescriber lacked proper authority. While tolerance to morphine develops in chronic users, the combination of multiple depressants, inadequate regulatory oversight, and lack of documented safeguards for long-term narcotic use contributed to her death. Better medication review, compliance with prescribing regulations, and consideration of alternative pain management strategies could have prevented this outcome.
