Complications of a seizure in the setting of prescription drug abuse (pregabalin)
AI-generated summary
Samantha Leech, 28, died from complications of a seizure in the setting of prescription drug abuse, particularly pregabalin. She obtained approximately 4000 pregabalin tablets over three months by visiting multiple GPs, using false identities (altered date of birth and maiden name). Despite Medicare alerts identifying her as a 'prescription shopper', many prescribers were unaware of pregabalin's abuse potential or failed to investigate her claims adequately. Post-mortem toxicology revealed dangerously high pregabalin levels (~56mg/L, toxicologically significant at 20-25mg/L) combined with methadone, oxycodone, and amitriptyline—a combination causing CNS depression. The case highlights systemic failures: pregabalin was not monitored by SafeScript (Victoria's real-time prescription monitoring system), prescribers lacked awareness of misuse risks, and SafeScript reliance on accurate patient details failed when false identities were used. This preventable death underscores the need for mandatory SafeScript monitoring of pregabalin and enhanced prescriber vigilance.

Coroner's recommendations
- The Victorian Department of Health review the circumstances of Ms Leech's death including the apparent ease with which she presented to multiple clinics, registered as a patient under her maiden surname and altered date of birth, and was prescribed significant quantities of pregabalin
- The Victorian Department of Health expedite review and include pregabalin to the list of medicines monitored through the SafeScript system and implement any other measures that could enhance patient safety in this regard
