FDA Adverse Event Monitoring System (AEMS)

[Formerly FDA Adverse Event Reporting System (FAERS)]

FDA Adverse Event Monitoring System (AEMS)

FDA is implementing the Adverse Event Monitoring System (AEMS) to consolidate multiple disparate reporting systems currently used across all FDA-regulated product categories, including medical products, vaccines, devices, tobacco, food, cosmetics, and veterinary medicines.

This unified platform is designed to enhance data quality and consistency through standardized reporting protocols, streamline reporting processes to reduce administrative burden on both internal FDA staff and external stakeholders, and strengthen safety surveillance capabilities through advanced case processing workflows, AI-based redaction and digitization tools, enhanced analytics, and comprehensive cross-product surveillance.

Beyond adverse event reporting, AEMS will serve as a centralized platform for managing consumer complaints, regulatory misconduct reports, and whistleblower submissions across all FDA centers. This comprehensive approach will enable more effective safety monitoring, facilitate trend identification across diverse product categories, and support timely regulatory decision-making to protect public health through improved data integration and analysis capabilities.

The FDA Adverse Event Reporting System (FAERS) database contains adverse event reports, medication error reports and product quality complaints resulting in adverse events that were submitted to FDA. The database is designed to support the FDA's post-marketing safety surveillance program for drug and therapeutic biologic products. The informatic structure of the FAERS database adheres to the international safety reporting guidance issued by the International Conference on Harmonisation (ICH E2B). Adverse events and medication errors are coded using terms in the Medical Dictionary for Regulatory Activities (MedDRA) terminology.
