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