Tools 12

Tool	Type	What it does
`dailymed_search_labels`	read	Search FDA drug labels (SPLs) Search Structured Product Labels (SPLs) — one label per marketed drug product. Filter by drug name, NDC, RxCUI, UNII, application (NDA/ANDA) number, marketing category, or publish date. Returns setid, title, spl_version and published_date for each match (use the setid with dailymed_get_label and the label_* tools). DailyMed v2: GET /spls.
`dailymed_get_label`	read	Get full SPL label document (XML) Fetch the complete Structured Product Label for a SETID as HL7 v3 SPL XML — the full FDA-approved labeling: indications, dosage, warnings, boxed warning, adverse reactions, active/inactive ingredients, etc. NOTE: DailyMed serves the full document only as XML (there is no JSON form), so this returns raw XML text. Use dailymed_search_labels first to find the setid. DailyMed v2: GET /spls/{setid}.xml.
`dailymed_label_history`	read	Get label version history List every published version (spl_version + published_date) of a label for a SETID — useful to see how a drug's labeling has changed over time. DailyMed v2: GET /spls/{setid}/history.
`dailymed_label_ndcs`	read	Get NDC codes for a label List the National Drug Codes (package-level NDCs) associated with a label's current version, for a SETID. DailyMed v2: GET /spls/{setid}/ndcs.
`dailymed_label_media`	read	Get label media (images) List media assets (product/packaging images, with mime_type and URL) for a label's current version, for a SETID. DailyMed v2: GET /spls/{setid}/media.
`dailymed_label_packaging`	read	Get label packaging & ingredients Get packaging descriptions plus product names and active ingredients (name + strength) for each product in a label, by SETID. DailyMed v2: GET /spls/{setid}/packaging.
`dailymed_list_drug_names`	read	List / search drug names List drug names in DailyMed (name + name_type B=brand/G=generic). Pass drug_name to filter by a substring — a fast way to discover exact spellings before searching labels. DailyMed v2: GET /drugnames.
`dailymed_list_ndcs`	read	List all NDC codes List National Drug Codes across all labels in DailyMed (paginated; the full set is large). DailyMed v2: GET /ndcs.
`dailymed_list_rxcuis`	read	List product-level RxCUIs List product-level RxNorm concept identifiers (rxcui + rxstring + rxtty term type) known to DailyMed (paginated). DailyMed v2: GET /rxcuis.
`dailymed_list_uniis`	read	List UNII active moieties List FDA UNII codes and their active-moiety names (paginated). Use a unii_code to filter labels in dailymed_search_labels. DailyMed v2: GET /uniis.
`dailymed_list_drug_classes`	read	List drug classes List pharmacologic drug classes linked to labels (code, coding system, type — e.g. EPC Established Pharmacologic Class — and name). DailyMed v2: GET /drugclasses.
`dailymed_list_application_numbers`	read	List FDA application numbers List FDA application numbers (NDA/ANDA/BLA) with their marketing category code, across all labels (paginated). DailyMed v2: GET /applicationnumbers.
