Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab facility who recognize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals often 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 rehabilitation facility which has experience in dealing with this type of detox, and where the person can receive additional rehabilitation services to handle all addiction issues.
