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