Cause of death
toxic effects of oxycodone
AI-generated summary
A 33-year-old man died from oxycodone toxicity after his general practitioner prescribed escalating doses of the opioid for intermittent migraines over 14 months (5-30mg daily), despite a prior rejection of a pethidine application for the same indication due to addiction and adverse effect risks. The prescriber did not recognize opioid dependence development or exercise appropriate caution regarding long-term daily opioid use for a condition for which clinical guidelines recommend against such prescribing. Multiple clinicians and Schedule 8 regulatory authorities were involved. The coroner identified significant gaps in regulatory oversight and lack of specialist input, recommending consultation between regulators and peak medical bodies on appropriate opioid use for migraine and systematic review of current permits.

Specialties
Error types
Contributing factors
- inappropriate prescribing of oxycodone for intermittent migraines
- escalating daily oxycodone doses (5mg to 30mg) without specialist review
- failure to recognize opioid dependence development
- lack of appropriate monitoring for drug-seeking behaviour despite increasing dose escalation
- prescription of multiple opioid analgesics concurrently (codeine, pethidine, morphine, dextropropoxyphene, tramadol, oxycodone)
- inadequate regulatory oversight by Drugs and Poisons Regulation in assessing clinical appropriateness of Schedule 8 permits
- lack of pain management plan documentation
- insufficient consideration of clinical guidelines recommending against opioids for migraine
- misrepresentation of compliance by patient, who concealed actual opioid use patterns
Coroner's recommendations
- The Victorian Department of Health should consult with relevant peak medical bodies such as the Australian and New Zealand College of Anaesthetists' Faculty of Pain Medicine and the Royal Australasian College of Physicians' Australasian Chapter of Addiction Medicine to obtain expert advice on the clinical appropriateness of (1) short-term opioid prescribing to treat migraine, and (2) long-term (greater than eight weeks) continuous opioid prescribing to treat migraine.
- Having obtained expert advice on use of opioids to treat migraine, Drugs and Poisons Regulation should review its procedures to ensure any application nominating migraine (intermittent or otherwise) as the clinical diagnosis for prescribing a Schedule 8 opioid is evaluated consistently with the expert advice.
- Having obtained expert advice on use of opioids to treat migraine, Drugs and Poisons Regulation should review all current valid permits nominating migraine (intermittent or otherwise) as the clinical diagnosis for prescribing a Schedule 8 opioid, and assess whether each permit was issued consistently with the expert advice. Drugs and Poisons Regulation should take appropriate steps to notify prescribers and, if necessary, cancel permits that were not issued for appropriate clinical diagnoses.
