Methadone detoxification is a process which should be overseen by drug addiction professionals within a drug rehab center who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must 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 person can receive additional rehabilitation services to deal with all addiction issues.
