FDA Adverse Event Reporting System — patient-reported adverse drug reactions.
Every record in this dataset can be traced back to its primary source at https://api.fda.gov/drug/event.json. Source-specific terms apply. US federal employee-authored works are generally public domain under 17 USC 105; non-federal and third-party material retains source terms. Free or keyless access does not alter source terms. AI Analytics-authored metadata and normalization are CC0 only where expressly stated.
