Methadone detoxification is a course of action which must be overseen by drug addiction professionals within a drug rehab center who realize how difficult and challenging 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 often 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 should only be done under close supervision at a drug rehabilitation program which has practical experience in dealing with this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
