Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab program who realize how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab 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.
