Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab program who realize 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 individuals typically revert back to methadone to alleviate 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 facility which has experience in handling this type of detoxification, and where the individual can receive further treatment services to deal with all addiction issues.
