Methadone detoxification is a process which must 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 individuals often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab 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.
