Methadone detoxification is a process which should be overseen by addiction professionals within a drug rehab facility who recognize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation center which has practical experience in dealing with this type of detoxification, and where the person can receive additional treatment services to deal with all addiction issues.
