Methadone detoxification is a course of action which should be supervised by drug addiction professionals within a drug rehab facility 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 individuals frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the individual can receive additional treatment services to address all addiction issues.
