For clinicians and pharmacists. FDA drug labeling and the clinical terminology systems — LOINC, MeSH, ICD-10 — that the Codex holds. Ask about a contraindication, a boxed warning, or a dose and get the labeled language, quoted, with its source. Where the label is silent, it abstains. It does not summarize away a warning, and it does not invent one.
Labeled facts only. Where the label is silent, the Codex is silent.
The experience
A paraphrased warning can lose the very qualifier that matters. The Codex quotes the labeling instead of summarizing it, so what you read is what the FDA-approved label says — and where the label does not address your question, it tells you so rather than filling the gap.
Indications, dosing, warnings — the approved labeling, quoted, not a digest of it.
What the label says not to do, in the label's own words, with the source.
The most serious labeled risks, surfaced first and quoted exactly.
LOINC, MeSH and ICD-10 codes and their definitions, resolved from the held terminology.
What comes back
You ask in the language of the chart and the counseling window. Every card below is the shape of a real answer — a verbatim quote with its citation and provenance, or an honest abstention. The abstention is not a failure; it is the guarantee.
“Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias.” The label directs discontinuation and instructs against use in patients with severe renal impairment.
The most serious labeled risk, quoted from the approved label — surfaced first, not buried.
4548-4 — “Hemoglobin A1c/Hemoglobin.total in Blood.” The standard laboratory observation code for a glycated-hemoglobin measurement.
The terminology systems resolve a code to its exact meaning — the interoperability layer under the note.
The held labeling does not address this. If the approved label carries no pediatric dosing for that age, the Codex will not extrapolate one — there is no labeled figure to quote, so it abstains.
Off-label extrapolation is exactly where an invented number does harm. The Codex answers only what the label states; where the label stops, it stops — and says so.
Once you're in
You will be invited, and you will sign in at maat.surgexi.com. Here is how to get the most out of it from the first minute.
Your invitation opens a medical account scoped to drug labeling and clinical terminology. You search the label, not the open web.
“Contraindications for [drug],” “boxed warning for [drug],” “labeled dose for [indication].” The answer is the labeled language, quoted, with the section it came from.
Ask for boxed warnings and contraindications first. The Codex surfaces them verbatim, so the qualifier that matters is never lost to a summary.
Ask for a LOINC, MeSH or ICD-10 code or its meaning; the Codex returns the exact term — the interoperability layer beneath a note or an order.
Paste a note or a draft handout into Verify; each drug fact is checked against the labeling, and anything the label does not support is flagged.
When the Codex says the label does not address your question, that is the labeled record's true boundary. It will not extrapolate a dose or a use the label does not carry — and neither should the note.
