Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehabilitation facility who realize how difficult and challenging methadone detoxification can be. Methadone detox is regarded to be far more serious 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 relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the individual can receive additional treatment services to deal with all addiction issues.
