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