Pharmacovigilance

Pharmacovigilance is the process and science of monitoring the safety of medicines and taking action to reduce the risks and increase the benefits of medicines. It is a key public health function.

The EU pharmacovigilance system is one of the most advanced and comprehensive in the world and represents a robust and transparent instrument to ensure a high level of public health protection throughout the EU. It provides a system for monitoring the safety of medicines on the European market through prevention, detection and assessment of adverse reactions to medicines, including those due to medication errors and overdose. In addition, patients can report adverse drug reactions directly to the competent authorities.

Those involved in pharmacovigilance

Legal framework

The legal framework of pharmacovigilance for medicines marketed within the EU is provided for in Regulation (EC) No 726/2004 with respect to EU authorised medicinal products and in Directive 2001/83/EC with respect to nationally authorised medicinal products (including those authorised through the mutual recognition and decentralised systems).

In addition, Commission Implementing Regulation (EU) No 520/2012 outlines the practical details to be respected by marketing authorisation holders, national competent authorities and the EMA and Commission Commission Delegated Regulation (EU) No 357/2014 on post-authorisation efficacy studies specifies the situations in which such studies may be required.
