Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who recognize how challenging and difficult methadone detox can be. Methadone detoxification 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 ease symptoms. This is why methadone detox must 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 further treatment services to deal with all addiction issues.
