Data sources

14 archives are downloaded, checksummed, recorded and joined. Each entry below is the anchor target for the source markers that appear throughout the site — including on every block of prescribing information.

All source data is public domain. These are works of the United States federal government and are not subject to copyright protection in the United States. OpenRx adds the schema, the joins and the interface; it adds no clinical claim.

openFDA — Human Drug Adverse Events (FAERS)

FDA

Post-market safety reports from the FDA Adverse Event Reporting System, ingested as aggregate report counts per active ingredient rather than as raw records. The bulk archive is 1,767 partitions totalling roughly 159 GB — not ingestible at any reasonable cost — so OpenRx queries the openFDA API for the total report count per ingredient and sums those onto each medication. See the methodology for why this figure must not be read as a risk measure.
