Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab program 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 individuals 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 detox should only be done under strict supervision at a drug rehabilitation center which has experience in handling this type of detox, and where the individual can receive further treatment services to handle all addiction issues.
