Methadone detoxification is a course of action which should be supervised by drug addiction professionals within a drug rehab facility who recognize how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more serious 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 detox must only be done under close 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 address all addiction issues.
