Pharmacovigilance (abbreviated PV or PhV) is the pharmacological science relating to the detection, assessment, understanding and prevention of adverse effects, particularly long term and short term side effects of medicines. Generally speaking, pharmacovigilance is the science of collecting, monitoring, researching, assessing and evaluating information from healthcare providers and patients on the adverse effects of medications, biological products, herbalism and traditional medicines with a view to:
* identifying new information about hazards associated with medicines
* preventing harm to patients.
The etymological roots are: pharmakon (Greek), “drug;” and vigilare (Latin), “to keep awake or alert, to keep watch.”
