API returns code not found

Question

For a number of codes found in the National Drug Code directory the API returns code not found. https://www.accessdata.fda.gov/scripts/cder/ndc/index.cfm

I have reviewed the API documentation and tried building a number of queries to try and look up information about a drug given the package ndc. all return a code:"Not_Found" error.

Here's a list of a few different api calls I have tried.

https://api.fda.gov/drug/label.json?search=package_ndc:%2225021-166-48%22

https://api.fda.gov/drug/ndc.json?search=package_ndc:%2225021-166-48%22

https://api.fda.gov/drug/label.json?search=product_ndc:%2225021-166-48%22

https://api.fda.gov/drug/ndc.json?search=product_ndc:%2225021-166-48%22

I have tried removing the hyphens, putting the search field in quotes, and adding a limit at the end with an &

Can anyone advise on how to get information about a drug with the API by ndc code?

Answer 1

The correct URL to get the NDC record is this. Please note that package_ndc is a sub-field of the top-level packaging element.

The correct URL to get the label is this. Please note that package_ndc is a sub-field of the top-level openfda element.

You can determine correct path to the fields you need by looking at the "Searchable Fields" documentation on the openFDA website.
