Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab program who realize how difficult and challenging methadone detox can be. Methadone detoxification is known 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 should only be done under strict supervision at a drug rehabilitation facility which has practical experience in handling this type of detoxification, and where the person can receive further rehabilitation services to handle all addiction issues.
