Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation 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 typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the individual can receive additional recovery services to deal with all addiction issues.
