Methadone detoxification is a course of action which must be supervised by addiction professionals within a drug rehab program who realize how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals often 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 close supervision at a drug rehab center which has experience in dealing with this type of detox, and where the person can receive further treatment services to handle all addiction issues.
