Methadone is a long-acting synthetic opioid medication used primarily in the management of opioid dependence and chronic pain. It is commonly prescribed as part of medication-assisted treatment (MAT) programs to help individuals reduce or quit their use of heroin or other opiates. Methadone is available in various forms, including tablets, oral solutions, and injectables.

Methadone is a cornerstone of MAT for opioid use disorder. It helps reduce cravings and withdrawal symptoms, stabilizing individuals and allowing them to engage in therapy and support programs. By preventing withdrawal symptoms and reducing cravings, methadone helps individuals maintain abstinence from illicit opioids.
