Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehabilitation facility who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users 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 center which has practical experience in dealing with this type of detox, and where the individual can receive additional recovery services to handle all addiction issues.
