Pharmacovigilance is the art and science of detection, understanding and prevention of adverse drug reactions and not merely a critical analysis of prescriptions and errors. This field starts with reporting by clinicians of a suspected adverse drug reaction (ADR) to the pharmacologist followed by joint causality analysis and ends at the application of new information by a clinician for benefit of patients. There are a number of ways, which can be utilised for reporting adverse effects using pen and paper format to software applications for smart phones. Varied types of activities spreading from systematic reviews to the mechanistic evaluation of ADR can be performed under the umbrella of pharmacovigilance. It is of utmost importance for clinicians to understand how to identify, communicate and understand adverse effects of drugs with an aim to prevent harm to patients.
