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