Methadone detoxification is a course of action which should be supervised by addiction professionals within a drug rehab facility who realize how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
