Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation facility who understand how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to relieve 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 treatment facility which has experience in dealing with this type of detox, and where the individual can receive further rehabilitation services to handle all addiction issues.
