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