An adverse event (side effect) is any unintended medical occurrence in a patient who has been given a pharmaceutical product that may or may not have been caused by treatment with the product. An adverse event (side effect) can therefore be any unfavorable and unintended sign, symptom, or disease associated with the use of the product.
