Data sources

What we monitor, and what we do not.

FormularySignal watches public FDA/openFDA shortage records and attaches source links so teams can verify records in their own review process.

It is source-linked monitoring, not clinical, purchasing, sourcing, procurement, inventory, substitution, dispensing, or emergency advice.

Primary source

FDA/openFDA drug shortage records

Scheduled checks compare public shortage records against customer watch terms. Record timing, corrections, classifications, omissions, and API availability are controlled by the public source.

Context source

FDA RSS updates

Where available, Signal Cards can attach matching public FDA RSS context for verification. RSS context is not treated as clinical or procurement instruction.

RxNorm

RxNorm lookups can provide public normalized names that help compare organization-level watch terms against public shortage records. Matching remains a relevance signal, not a medical rating.

Context source

openFDA NDC and DailyMed

When public package context is available, Signal Cards can include labeler, dosage form, route, product count, package count, and DailyMed label links for source verification. FormularySignal does not interpret label warnings or clinical content.

ASHP/UUDIS shortage bulletins

ASHP/UUDIS bulletins may be useful external context for human reviewers. FormularySignal does not copy, summarize, rewrite, redistribute, or synthesize from ASHP/UUDIS bulletin content. Unless licensed handling is added later, ASHP is treated as external link/title/date context only.
