Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehab program who realize how challenging and difficult methadone detox can be. Methadone detox 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab program which has practical experience in handling this type of detoxification, and where the individual can receive further treatment services to address all addiction issues.
