Data Sources & Methodology
How each section of this page is sourced, and how often the data is refreshed.
| Source | Endpoint | Refresh |
|---|---|---|
| FAERS reactions | openFDA /drug/event.json count API. Aggregated per drug per reaction term; we do not store individual reports. | Daily |
| Recalls | openFDA /drug/enforcement.json. Drugs matched via three confidence-tracked strategies: structured generic name (HIGH), NDC code bridge (MEDIUM), text token parse (LOW). Only HIGH and MEDIUM matches surface here. | 6 hours |
| Shortages | FDA Drug Shortages list. | Daily |
| Boxed warnings & label sections | openFDA /drug/label.json. Labels are stable; monthly cadence is sufficient. | Monthly |
| Condition categories | Synonym-mapped from drug_labels.indications. Methodology at /methodology/. | Per-drug |
What we do not do. We do not invent, paraphrase, or extrapolate drug claims. Every figure on this page comes from a query against an openFDA endpoint. If the data is unavailable, the section gracefully omits rather than filling the space with editorial guesswork.
