Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug treatment facility who understand how challenging and difficult methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehabilitation center which has experience in dealing with this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
