Being part of the bigger picture

Information about adverse effects from patients, reported by health professionals or patients themselves, makes the long journey, via the national pharmacovigilance centre, into WHO’s global database, where medicines safety issues across the world can be identified.


Countries participating in the WHO Programme forward their reports to UMC where they are entered into VigiBase, the WHO global database of individual case safety reports, which is maintained by UMC. VigiBase contains reports collected over nearly half a century. All reports are anonymous.

More than 150 countries that have national pharmacovigilance centres are members or associate members of the WHO Programme for International Drug Monitoring. UMC has provided technical and scientific support for this expanding programme since 1978.
