Methadone detoxification is a process which must be supervised by addiction professionals within a drug treatment facility who realize how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation facility which has practical experience in handling this type of detox, and where the person can receive additional rehabilitation services to handle all addiction issues.
