Methadone was once awesome in accordance with retention or longer length of medicine, fewer medicine dropouts, or discontinuation towards scientific recommendation.

On this learn about, dangers of loss of life if actively receiving MAT have been an identical for buprenorphine/naloxone and methadone, however methadone was once awesome as it’s taken for extra prolonged time classes.

Mavens had been involved that methadone get admission to for OUD stays restricted to methadone systems whilst buprenorphine/naloxone may also be prescribed by way of phone by way of maximum physicians.
