Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation program 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 alleviate symptoms. This is why methadone detox should only be done under strict supervision at a drug rehabilitation center which has experience in handling this type of detoxification, and where the individual can receive additional treatment services to handle all addiction issues.
