FDA National Drug Code Directory Scraper & API

Search the official FDA National Drug Code (NDC) Directory through openFDA. Get normalized product/package NDCs, brand and generic names, labeler, active ingredients and strengths, packaging, route, dosage form, application number, marketing category, and reported dates.

Searches

• Exact product NDC or package NDC
• Brand or generic name
• Labeler and active ingredient
• Route and dosage form
• Marketing category and application number
• Reported marketing status and marketing/listing date ranges

All modes share one total maxResults cap. maxCandidates bounds source pagination before local date/status filtering. Empty input uses exact brand OZEMPIC, deterministically sorts by product NDC, and returns one item. The bounded first run costs at most $0.0001 start + $0.002 per item = $0.0021.

Inputs

{"brandName":"OZEMPIC","maxResults":1}

{"productNdc":"0169-1704","maxResults":10}

{"packageNdc":"0169-1704-30","maxResults":1}

{"activeIngredient":"SEMAGLUTIDE","route":"SUBCUTANEOUS","marketingStatus":"CURRENT","maxCandidates":100,"maxResults":25}

marketingStatus=CURRENT means no elapsed reported marketing end date was observed. It does not establish market availability. Date filters use YYYY-MM-DD.

Output and explicit outcomes

Found items include normalized non-null ingredient, package, and route arrays; source query/retrieval evidence; bounded-query disclosure; and mandatory interpretation limits. A search with no result emits NO_MATCH. Retry exhaustion emits SOURCE_UNAVAILABLE instead of a silent empty dataset.

Evidence boundaries

NDC data is labeler-submitted product-listing evidence. An NDC listing is not:

• FDA approval or endorsement;
• proof of current manufacture, distribution, inventory, or market availability;
• therapeutic-equivalence, safety, efficacy, quality, authenticity, or recall evidence;
• prescribing, diagnosis, or treatment advice;
• a complete historical or current-state determination.

Marketing start/end and listing expiration dates are administrative fields and require careful interpretation. A missing result does not prove a product is absent, discontinued, unapproved, unavailable, or inauthentic. unapprovedCategory only identifies marketing-category text reported by the source; it does not independently adjudicate legal or approval status. Confirm consequential decisions with FDA's relevant product/application databases, labeling, recalls, and qualified professionals.
