What it answers

Look up an over-the-counter or prescription product's FDA-submitted label and get back the sections the labeler wrote — what is in it, what it is for, how to take it, and what the labeler warns about — each as the paragraphs they printed, in label order, at the label's latest submitted version. This includes the Drug Interactions section, and what that section is matters: it is one sponsor's statement about their own product, not a curated interaction database and not a determination about any pair of substances. No public-domain primary source for drug-drug interactions exists, and the answer says so every time it returns one. Every label cites the exact document version and the labeler's own effective date.

Ask it things like

  • What does the label on this bottle say about interactions?
  • What are the active ingredients in NDC 0002-4462?
  • What warnings does this product's label carry?
  • What is this drug's label for?

What comes back

A receipt, and the same envelope on every tool — so a caller writes against one contract whichever one they call. The citations carry two clocks that are never collapsed: citature's retrieved_at and the source's own as_of, plus the record's own published_at and record_version where the source publishes them.

Answer


citature — drug_label_lookup receipt


answer
The rows themselves, typed per tool. Amounts carry their unit and their basis, because a figure per serving and one per 100 g are not comparable.
citations
The record behind the answer: a re-runnable upstream URL, citature's retrieval clock, the release's own currency date, and the record's own version.
coverage
What this answer does not reach, and where the record is silent rather than negative.
guardrails
The standing caveats, shipped in the answer itself rather than only on a page an agent never loads.
matches
Every join the answer used, named by method and confidence. A name match is reported as a name match, never as an identity.
schema_version
The conformed schema the answer was produced against, so a caller can pin it.

What this figure is

The envelope's fields and what each one holds, with no values in them: a filled specimen would be a figure that names no record, which is the one thing citature does not publish. Every tool that answers over a record returns this same shape, so a caller writes against one contract whichever of them they call.

guardrails & coverage

  • Research over public records and product labels — not medical, nutritional, or safety advice.
  • citature reports what the record says. It never renders a verdict, a pass/fail, a diagnosis, or a recommendation, and is not a substitute for a clinician.
  • Answers are product-, substance- or population-level only — foods, supplements, labels, substances, enforcement actions, and dietary intake as a weighted survey estimate. No answer returns or describes an individual person, and citature links no record to individually identifiable data.
  • A record that does not declare something is not a record declaring its absence. citature reports what a record states; it cannot report what a product does not contain, or what a population did not consume.
  • A Daily Value is a labelling reference from federal regulation, not a Dietary Reference Intake. citature carries no licensed source for Dietary Reference Intakes and does not estimate whether anyone meets a nutrient requirement.
  • Coverage reflects the records citature has ingested, not the full upstream history. Each dataset advances when its source publishes a release.
  • Every answer states its own coverage caveats in the receipt's `coverage` field, alongside these standing guardrails.
