Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation program who recognize how difficult and challenging 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 relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehabilitation program which has experience in dealing with this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
