FDA Adverse Events Reporting System Drug 2020

The FDA Adverse Event Reporting System (FAERS) contains information on medication errors, quality complaints and drug-related adverse events that were submitted to FDA (U.S. Food and Drug Administration) in 2020. The Drug dataset contains drug/biologic information for as many medications as were reported for the event (1 or more per event).

FAERS (FDA Adverse Event Reporting System) is designed to support the FDA’s post-marketing safety surveillance program for drug and therapeutic biologic products. It is a useful tool for FDA (U.S. Food and Drug Administration) for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer’s compliance to reporting regulations and responding to outside requests for information. The reports in FAERS are evaluated by clinical reviewers in the Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and Research (CBER) to monitor the safety of products after they are approved by FDA. If a potential safety concern is identified in FAERS, further evaluation is performed. Further evaluation might include conducting studies using other large databases, such as those available in the Sentinel System. Based on an evaluation of the potential safety concern, FDA may take regulatory action(s) to improve product safety and protect the public health, such as updating a product’s labeling information, restricting the use of the drug, communicating new safety information to the public, or, in rare cases, removing a product from the market.

The reports in FAERS are submitted to FDA by healthcare professionals (such as physicians, pharmacists, nurses and others) and consumers (such as patients, family members, lawyers and others). Healthcare professionals and consumers may also report to the products’ manufacturers who then send these reports to FDA.
