Submitting Field Alert Reports (FARs) to CBER


The purpose of field alert reports (FARs) is to quickly identify drug products in distribution that pose potential safety threats. Within 3 days of discovering significant problems with distributed drug product, holders of approved new drug applications (NDAs) or abbreviated new drug applications (ANDAs) must submit a FAR to FDA to comply with 21 CFR 314.81(b)(1).
What must be reported?

  • Incidents that cause the drug product or its labeling to be mistaken for or applied to another article;
  • Bacterial contamination;
  • Any significant chemical, physical, or other change or deterioration in the distributed drug product;
  • Any failure of one or more distributed batches of the drug product to meet the specifications established in its application.
