Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab facility who realize 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 relieve 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 program which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
