Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehab facility who recognize how challenging and difficult methadone detox can be. Methadone detoxification is known 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 ease symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detoxification, and where the individual can receive additional rehabilitation services to address all addiction issues.
