Privacy statement

Pharmacovigilance Centre Lareb is the Dutch knowledge centre for adverse reactions to drugs and other health products. Adverse drug reactions (ADRs) can be reported using the reporting form on this website. Each report of an ADR is carefully analyzed and recorded in a central database. Reports are anonymously displayed on this website. In addition, knowledge about ADRs and Lareb is distributed via this website

ADR reports

Personal information that is asked for on the reporting form is handled according to the General Data Protection Regulation (GDPR) and the general privacy regulation of Pharmacovigilance Centre Lareb. The general privacy regulation of Pharmacovigilance Centre Lareb is only available in Dutch. Personal information that is asked for is used for the registration of the ADR report and communication with the reporter. In order to detect duplicate reports, Pharmacovigilance Centre Lareb checks if the case already has been reported by using the patient’s date of birth and gender. Reporters may be approached for extra information about the case. In addition, reporters may be asked to fill in a questionnaire about the quality of the service of Pharmacovigilance Centre Lareb. The results of this questionnaire are exclusively shared with the management of Pharmacovigilance Centre Lareb.

Personal information
The following personal information is collected:

From the reporter:

  • E-mail address (for registration and correspondence between reporter and Pharmacovigilance Centre Lareb)
  • 4 digits postal code (for mapping of distribution of reporting of vaccines within the Netherlands; reporting of postal code is not mandatory)

From the patient who experienced the ADR:

  • Gender
  • Date of birth
  • Drug use and indication
  • Medical information
  • Experienced adverse drug reaction(s)
  • BSN number (citizen service number, no mandatory and only requested for reports concerning a corona vaccine)

Sharing with third parties 
Reported ADRs are shared, without personal information of the reporter and patient, (with the exception of the patient’s age and gender) to the Netherlands Medicine Evaluation Board (CBG), the European Medicines Agency (EMA), the World Health Organization (WHO) and the marketing authorization holders (MAHs) of the suspected drug. The aim of forwarding the reports to these third parties is to monitor the safety of drugs nationally as well as internationally.

In addition, anonymised reports are incidentally shared with the Federation of Dutch Thrombosis Services (FNT), the Health and Youth Care Inspectorate (IGJ), the Netherlands Food and Consumer Product Safety Authority (NVWA), Dutch Pharmacy Association (KNMP), the National Institute for Public Health and the Environment (RIVM), the Dutch Institute for Rational Use of Medicine (IVM) and Eurocat (researchgroups of the University Medical Centre of Groningen).

Description of automatized data collection
All data collected on the reporting form is automatically processed and stored in the database of Pharmacovigilance Centre Lareb. This is a shielded database; only authorised staff members of the Pharmacovigilance Centre Lareb have access to this database.
The Pharmacovigilance Centre Lareb has been authorized by the National Institute for Public Health and the Environment (RIVM), to request the citizen service number (BSN) in the case of an unknown corona vaccine and/or unknown batch number of a corona vaccine. By using the citizen service number (BSN), information on the administered vaccine can be retrieved from the vaccine register at the National Institute for Public Health and the Environment (RIVM). This retrieval of information is done via a secure setting. As soon as the information on the vaccine and the batch number are known, the citizen service number (BSN) is removed from the database.
