Medications and medical devices are designed to treat diseases or aid in their treatment. However, evidence shows that they may also cause unexpected reactions, which can range from mild to moderate or severe.
In 2002, the World Health Organization (WHO) defined pharmacovigilance as the science and activities related to the detection, assessment, understanding, and prevention of adverse effects of medicines or any other health-related issues. The goal is to identify new adverse reactions and prevent harm to patients.
