Pharmacovigilance is the science and activities related to the detection, assessment, understanding, and prevention of adverse reactions or any other health problem associated with medicines or vaccines.
Pharmacovigilance seeks to ensure that the benefit-risk balance remains favorable throughout the entire life cycle of a medicine, that is, from the time it is authorized until it is withdrawn from the market or its production is discontinued.
