Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation center who understand how challenging and difficult 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 often 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 must only be done under strict supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detoxification, and where the individual can receive further treatment services to handle all addiction issues.
