Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehabilitation program who understand how difficult and challenging methadone detox can be. Methadone detoxification is regarded 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 detox must only be done under strict supervision at a drug rehabilitation center which has experience in dealing with this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
