What is OpenVigil?

OpenVigil 1 and 2 are software packages to analyse pharmacovigilance data. There are several national and international databases of so called spontaneous adverse event reports, e.g., the U.S. american FDA Adverse Event Reporting System (AERS, mostly domestic data) or the WHO Uppsala Monitoring Centre (international). Currently, analyses of FDA AERS (LAERS & FAERS) pharmacovigilance data are available. In addition to U.S. american data, we are currently importing German data. Data mining features include highly configurable search criteria filters and output filters. Analyses include disproportionality analyses for signal detection like Proportional Reporting Ratio (PRR) calculations. Results can be viewed, sorted and filtered in the webbrowser or saved for further analyses in statistical software packages. Both projects aim at integrating these and other pharmacolovigilance sources to pharmacoepidemiological data like prescription data.
OpenVigilFDA is a fron-end to the openFDA-interface which is being developed by the FDA since 2014. It allows you to extract the latest reports. Due to technical limitations, the beta-version status and the ongoing changes to the API of openFDA, OpenVigil 2 is more stable and superior for analyses of disproportionality.

Where can I access OpenVigil?

There are live installations with U.S. american FDA pharmacovigilance data of both versions of OpenVigil with FDA AERS data and OpenVigilFDA freely available at Christian Albrecht University (CAU) of Kiel, Germany:

OpenVigil 2.0 (data 2004Q1-2012Q2):

OpenVigil FDA:

OpenVigil 1:
(development version at:

OpenVigil 2 and OpenVigilFDA are the successors of OpenVigil 1 and use cleansed FDA AERS data. For scientific research on U.S. american data, do not use OpenVigil 1 but only version 2 or OpenVigilFDA!

There is also a development version of OpenVigil 1 with German pharmacovigilance data available for preview:
OpenVigil 1 German:

We are also working on a development version of OpenVigil 1 with Canadian pharmacovigilance data (database is currently sill empty):
OpenVigil 1 Canadian:
The German and Canadian pharmacovigilance data are of sufficient quality and do not need further drugname-mapping prior to mining or analysing them.

Where can I download OpenVigil?

You can download the PHP-sources/executables of OpenVigil 1 and OpenVigilFDA and a WAR-file of OpenVigil 2.1 at sourceforge:
Source code of OpenVigil 2 will be made available soon, too, after some more improvement on code readability and documentation has been done.

The OpenVigil project does not produce or gather any of the pharmacovigilance data itself but is dependent on external data sources.
Our software is being developed for physicians, pharmacists and scientists. Due to the origin and nature of the data and the ongoing work on our programs, all results should be considered unvalidated. Especially, any findings must not uncritically be used for therapy changes or legal proceedings. However, these data are well usable for hypothesis generation.
