Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation program who understand 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 frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehabilitation facility which has experience in handling this type of detox, and where the person can receive further recovery services to deal with all addiction issues.
