I used this api call to get reaction list: https://api.fda.gov/drug/event?&search=???&count=patient.reaction.reactionmeddrapt.exact&limit=24

I just want to forward users to a page that provides more description about the MedDRA term. But I could only find MeSH's website providing such information. So currently I just put the MedDRA term as keyword to MeSH's website.

Part of the difficulty is that Meddra is a licensed product.


I am not aware of any place that offers the data online, since it is probably against the license agreement. At the top of the list is a minimal charge for non-commercial use, which might be a good option if you are just doing research.

  • Thanks. Hope the terms used by openfda could also become open data one day.
