Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab facility who understand 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 individuals often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the individual can receive further rehabilitation services to address all addiction issues.
