Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehabilitation program who recognize 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 frequently revert back to methadone to alleviate 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 center which has practical experience in handling this type of detoxification, and where the person can receive further rehabilitation services to handle all addiction issues.
