Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation center who realize 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 often 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 must only be done under close supervision at a drug treatment center which has experience in dealing with this type of detox, and where the person can receive additional treatment services to address all addiction issues.
