FDA
FDA maintains public drug shortage information and is the official public source for current and resolved shortage records that FormularySignal monitors.
Source comparison
FDA vs ASHP drug shortages.
FDA and ASHP shortage resources are both useful, but they are not the same product. FDA is the official public shortage source FormularySignal monitors; openFDA exposes machine-readable shortage records. ASHP provides a broader pharmacy-facing shortage resource. FormularySignal does not replace either source; it turns public FDA/openFDA checks into watchlist alerts for internal review.

openFDA
openFDA exposes FDA data through API endpoints, including the drug shortages endpoint used for machine-readable public-record monitoring.
ASHP
ASHP maintains a pharmacy-facing drug shortage resource with broader context. FormularySignal does not copy, summarize, rewrite, or synthesize ASHP bulletin content.
Where FormularySignal fits
FormularySignal is a monitoring layer for teams that already check public shortage records. It checks public FDA/openFDA records against organization-level watch terms and sends timestamped Signal Cards with source links. It is for oncology, infusion, specialty pharmacy, home infusion, anesthesia, ASC, and care-operation teams that need a cleaner reminder loop.
It is not ASHP, not FDA, not procurement software, not clinical decision support, not a sourcing tool, and not a local availability monitor.
Official-source caveat
Public records may change, data fields may differ by source, and national public shortage status may differ from local availability. Important records should be verified against official source pages before any operational action.
