The World Health Organization defines an adverse drug reaction as “any response that is noxious, unintended, or undesired, which occurs at doses normally used in humans for prophylaxis, diagnosis, therapy of disease, or modification of physiological function.” Adverse drug reactions are expected negative outcomes that are inherent to the pharmacologic action of the drug and not always preventable, while medication errors are preventable.[7][8][9]
