Methadone – Uses, Treatment Information, Safety & Medication Guide

Methadone is a prescription opioid medication used in specific medical settings for the management of severe pain and as part of treatment programs for opioid use disorder (OUD). It works by acting on opioid receptors in the brain and nervous system to reduce pain signals and help manage opioid dependence when used under professional medical supervision.

Because methadone is a long-acting opioid with complex effects, it requires careful dosing and monitoring by qualified healthcare providers. It carries risks including respiratory depression, dependence, tolerance, misuse, and serious drug interactions.
