Why FAERS

FAERS is the FDA's own collection of adverse event reports submitted by manufacturers, health professionals and consumers. It is the reference dataset behind most public drug safety analysis, updated quarterly and free to reuse.

Important interpretation note

FAERS is a spontaneous reporting system. A report does not establish that the drug caused the event, reporting rates vary widely between products and countries, and the same case may be submitted more than once by different senders. Use the data for signal generation and comparison, not as evidence of causation or as an incidence rate.

Notes

  • Reports are deduplicated by safety report id within a run.
  • openFDA refuses offsets beyond 25 000 records; narrow the filters to reach deeper into a large result set.
  • Numeric FAERS codes for reporter role, drug role and sex are decoded into readable labels.
