Search for drugs by brand or generic name.

Returns matching drugs with their RxCUI (the identifier you pass to get_drug), generic and brand names, and dosage form/strength when known. Use this first when you have a drug name but need its details or RxCUI.

Args: name: Brand or generic drug name, e.g. "aspirin" or "Lipitor". limit: Max results to return (1-50).

Get the full profile for a drug by its RxCUI.

Returns names, dosage forms, NDC codes, label sections, and related data. Get the RxCUI from search_drugs first if you only have a name.

Args: rxcui: RxNorm Concept Unique Identifier, e.g. "1191" for aspirin.

Get a drug profile by its NDC (National Drug Code) package code.

Use when you have an NDC from a label or packaging rather than a name.

Args: ndc_code: NDC code, e.g. "0363-0160".

Search for dietary supplements by name.

Returns matching supplements with their IDs (pass to get_supplement) and summary info. Use first when you have a supplement name like "Vitamin D" or "Fish Oil".

Args: name: Supplement name, e.g. "Vitamin D" or "magnesium". limit: Max results to return (1-50).

Get the full fact sheet for a supplement by its ID.

Check interactions across a mixed list of drugs and supplements.

Accepts 2-10 items (drug names, supplement names, or both) and returns known interactions among them. Interaction data comes from established medical databases; it is never generated or inferred, so an empty result means none were found in those sources, not that the combination is proven safe.

Args: items: 2-10 drug and/or supplement names, e.g. ["warfarin", "aspirin", "Fish Oil"].
