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