Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab facility who realize how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab program which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
