JAMA August 2026 Methadone vs Buprenorphine-Naloxone in Opioid Overdose Survivors

This study evaluates whether methadone or buprenorphine-naloxone is more effective at preventing mortality among high-risk individuals who have recently survived an opioid overdose. By tracking thousands of patients in Ontario over a several-year period, researchers discovered that those who began a methadone regimen experienced a lower risk of death within the first year compared to those prescribed the alternative. A key factor in this outcome appeared to be treatment retention, as patients stayed on methadone for a longer duration than those on buprenorphine-naloxone. However, the data also suggests that the protective benefits of both drugs are similar while actively taking the medication, highlighting that the primary challenge remains keeping patients engaged in care to prevent relapse and fatal outcomes.
