How this service works
NIH RxNorm concept lookup (RxNav): RxCUI identifiers for a drug name with each concept's name and term type (e.g. IN = ingredient, SCD = clinical drug). Up to 5 concepts per call. Exact-name lookup, no fuzzy matching.
Output
Returns up to 5 RxNorm concept objects, each containing the RxCUI numeric identifier, the canonical concept name as defined in RxNorm, and the term type code (e.g. IN for ingredient, SCD for semantic clinical drug, BN for brand name). Exact-name matching only — no fuzzy or partial matches.
Example use cases
Drug identifier resolution for EHR pipeline
“I need the RxCUI identifier and term type for 'atorvastatin' from RxNorm — give me up to 5 concepts so I can map it into our medication records.”
Validating drug ingredient classification
“Can you check what RxNorm term type 'amoxicillin' is — specifically whether it's classified as an ingredient (IN) or a clinical drug (SCD)? Pull up to 3 concepts.”
Standardizing drug name for formulary comparison
“I have the drug name 'hydrochlorothiazide' and need its official RxNorm concept ID and label so I can match it against our formulary database — please pull the top concept.”
Technical details
Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/rxnorm-concept-id?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to resolve a drug or ingredient name to its official NIH RxNorm RxCUI code and term type classification (e.g. ingredient vs. clinical drug vs. brand name). Ideal for pipelines that require standardized pharmaceutical identifiers, formulary matching, EHR data normalization, or any workflow consuming RxNorm-coded data. Not suitable when fuzzy or partial-name matching is required, or when you need full drug detail (use NLM DailyMed endpoints for labeling data). Prefer over general drug search APIs when RxCUI fidelity and term-type classification are specifically needed.
Side effects
- Drug name not found in RxNorm (zero concepts returned — exact match required, no fuzzy fallback)
- Name contains invalid characters beyond letters, digits, spaces, hyphens (rejected by schema validation)
- Name shorter than 2 or longer than 100 characters (schema validation error)
- max parameter outside 1–5 range (rejected)
- RxNav upstream unavailable (upstream timeout or error propagated)
- Misspelled drug names return empty results rather than suggestions
