ingredientidsQueryRequiredIngredient RXCUI(s)

(Space-separated list.)

All query parameters are case-insensitive.

Note that parameters must be "URL encoded", so a "space-separated list" in a URL will, in practice, usually appear to use either a plus sign (+) or %20 as the separator. For full information on URL encoding, please refer to IETF RFC 3986, "Uniform Resource Identifier".

Output structure

Results are available as either XML or JSON.

  • The XML result has the root element rxnormdata. It is described in the XML Schema for the RxNorm API; the relevant element structure is summarized below. Elements that would be empty might be left out.

  • The JSON result is an object {...}, analogous to the content of the XML rxnormdata. Fields that might occur multiple times in the XML are expressed as an array. Fields that would be empty might be null or left out. Numbers are expressed as strings.

Both XML and JSON results follow the same outline:
