Methadone detoxification is a course of action 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 known 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 alleviate 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 treatment services to deal with all addiction issues.
