Methadone detoxification is a course of action which should be supervised by drug addiction professionals within a drug rehabilitation facility who understand how difficult and challenging methadone detox can be. Methadone detox 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation center which has experience in dealing with this type of detoxification, and where the person can receive further recovery services to address all addiction issues.
