Reporting adverse events and/or product complaints

An adverse event is any untoward 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 is commonly referred to as a side effect and can be any unfavorable and unintended sign, symptom or disease associated with the use of a product. 

A product complaint is any inquiry or dissatisfaction with the identity, strength, quality or purity of a pharmaceutical product or medical device, including reports of suspected counterfeit/falsified product.
