Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users typically 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 should only be done under close supervision at a drug rehabilitation facility which has experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to handle all addiction issues.
