Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more serious 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 must only be done under close supervision at a drug rehab facility which has experience in dealing with this type of detoxification, and where the individual can receive additional treatment services to address all addiction issues.
