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 detoxification can be. Methadone detox is regarded to be far more serious 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 ease symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab center which has practical experience in dealing with this type of detoxification, and where the person can receive additional treatment services to handle all addiction issues.
