About Us

Purple Vigilance Limited is a Pharmacovigilance consultancy based in Hertfordshire that was established in 2011.  Although the business is relatively young, the Director, Ruth Casserley (nee Wilding) has worked in the pharmaceutical industry for over 25 years. She worked in various roles but realised that with her keen eye for detail and interest in patient safety she was well suited to a career in Pharmacovigilance.

In 2001 she established the Pharmacovigilance and Medical Information department at a leading generic company.  During the next 10 years she managed and developed the department and was the EU QPPV for the company.  She successfully implemented a safety database and in addition gained invaluable hands-on experience in many aspects of post authorisation Pharmacovigilance, ensuring that all systems remained compliant with the changing legislation.

After 10 years in this role, Ruth decided to take on a new challenge and Purple Vigilance was born.

The aim of Purple Vigilance is to ensure patient safety, whilst maintaining compliance with legislative requirements. We aim to provide high quality and cost-effective solutions, to support the requirements of companies of all sizes.

The company’s current assignments include provision of a full Pharmacovigilance service for an EU client and provision of regular Pharmacovigilance support to a Contract Research Organisation. Past assignments include training client staff on preparation and scheduling of PSURs, and presenting an update on the new Pharmacovigilance legislation to a client’s safety team.

A list of the services provided by Purple Vigilance can be found on the PV Services page, you can contact us for more information.
