Authoritative FDA drug label (Structured Product Labeling).
Authoritative FDA drug label (Structured Product Labeling). Give a drug name (brand, generic, or substance), or an exact NDC, RxCUI, or SPL set_id, and get back the FDA-approved label split into the sections agents need: boxed warning, indications and usage, dosage and administration, contraindications, warnings, adverse reactions, drug interactions, use in specific populations, pregnancy, mechanism of action, and active/inactive ingredients. Each record also carries identity metadata (brand/generic names, manufacturer, NDCs, RxCUIs, route, DEA schedule, OTC vs prescription) plus a hasBoxedWarning flag. Free, public-domain US government data. Point-in-time public records, not medical advice. Use for prescribing-support, pharmacy, and clinical agents that must read the real label rather than guess it.
