CONCLUSION: This study provides the first population-level analysis of medical narcotics utilization in South Korea’s non-reimbursed sector. The disproportionate exposure of young women to psychotropic anorexiants constitutes a compelling pharmacovigilance signal. Addressing this requires not only an integrated data infrastructure linking NIMS with national health insurance records, but also the restoration of meaningful professional oversight over prescribing outside the reimbursement system.
