Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab program who recognize 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 frequently revert back to methadone to ease 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 rehab facility which has experience in handling this type of detoxification, and where the person can receive further treatment services to deal with all addiction issues.
