FDA FAERS In Focus: Quarterly Alerts on Potential Drug Safety Risks

FDA safety staff monitoring the FAERS database for drug safety signals.

The FDA maintains a rigorous post-market surveillance system to protect public health through advanced Pharmacovigilance. Central to this is the FAERS (FDA Adverse Event Reporting System), a critical database used for Medical Monitoring and identifying potential Safety Signals associated with drugs and biologics. Also, FDA emphasized the importance of its quarterly reporting process, which is a cornerstone of global Signal Management strategies.

​What Does Inclusion on the FAERS List Mean?

​It is crucial to understand that if a drug appears on the FDA’s quarterly list, it does not mean a confirmed causal risk has been established. Instead, it indicates:

  • ​Potential Safety Signals are currently being evaluated by regulatory experts.
  • ​A need for further Aggregate Reporting and data analysis to confirm the risk.
  • ​Safety Advice: Patients and prescribers should not stop using the medication without consulting a healthcare professional.

​How the FDA Identifies Potential Safety Signals

​The process is mandated by the 2007 FDA Amendments Act, requiring the agency to screen the safety database and implement effective Signal Management.

​The Evaluation Workflow:

  1. ​Medical Monitoring: Safety staff in CDER and CBER routinely mine FAERS for patterns and adverse event trends.
  2. ​Pharmacovigilance Analysis: Once a “serious risk” is identified, it is logged into internal tracking systems for further scrutiny.
  3. ​Quarterly Publication: These findings are released to the public to ensure transparency for clinicians and stakeholders.

​Regulatory Actions and Transparency

​The goal of this Pharmacovigilance service is to increase transparency. If a safety signal is validated, the FDA may take measures such as:

  • ​Labeling Changes: Updating safety warnings based on new data.
  • ​REMS: Risk Evaluation and Mitigation Strategies.
  • ​Drug Safety Communications: Issuing official alerts to the public.

​Staying Updated

​A fresh report is posted every quarter with newly identified signals. Once all issues in a report are resolved through finalized Aggregate Reporting and regulatory decision-making, the report is moved to the archived section.
