Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab center who realize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more serious 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 detox must only be done under close supervision at a drug rehab program which has practical experience in dealing with this type of detox, and where the person can receive additional rehabilitation services to address all addiction issues.
