Combined drug toxicity (methadone, fentanyl, diazepam and pregabalin)
AI-generated summary
Daniel Joseph Herbert, aged 37, died from combined drug toxicity involving methadone, fentanyl, diazepam and pregabalin. He had a 17-year history of opioid dependence stemming from prescription OxyContin for a work-related back injury. In the three months before his death, he was prescribed pregabalin and diazepam by multiple doctors (Dr F. in Wangaratta and Dr K. in Albury) without apparent awareness of each other's prescribing, resulting in excessive cumulative doses. He also obtained illicit fentanyl. The coroner found no individual doctor exceeded appropriate single prescriptions, but the overlap between prescribers enabled excessive drug accumulation. The coroner recommended warning GPs about pregabalin's dependence potential and the need for caution with repeat prescriptions, similar to other drugs of dependence.

Coroner's recommendations
Provide this finding to the Royal Australian College of General Practitioners and consider warning members that when prescribing pregabalin with repeats, they should treat it with the same caution as any other drug of dependence
Improve coordination and awareness between prescribers treating patients with history of doctor-shopping to prevent overlap and excessive cumulative dosing
