I need a list of the adverse events for Avastin drug. I mainly would like to see a list of adverse events concerning vision issues.

This API call should help you get started with all adverse event (AE) reports involving Avastin:


but be sure to read through the comprehensive docs at https://open.fda.gov/drug/event/reference/ to see if you want to be searching for a subset of this data set which is where Avastin was the suspect drug. I am not 100% sure that would be possible through the API since you want to limit your search to a nested object.

To search for only AE reports where a certain AE related to vision was reported, you'll want to look through the list of all AEs from the above API call (https://api.fda.gov/drug/event.json?search=brand_name:avastin&count=patient.reaction.reactionmeddrapt.exact) and then filter based on those.

You can also use a more user-friendly tool that Brian Norris and I built at http://researchae.com. Here's a hyperlink to only Avastin AE reports.

Hope this helps and good luck!
