Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation program who recognize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under strict supervision at a drug treatment facility which has practical experience in handling this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
