Methadone detoxification is a process which should be overseen by addiction professionals within a drug rehabilitation program who recognize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehabilitation facility which has experience in dealing with this type of detox, and where the individual can receive additional rehabilitation services to address all addiction issues.
