About Reported Reactions
Reported Reactions counts the adverse event reports that FDA received for human drugs and medical devices. It shows the counts by drug, drug class, reaction term, device, device type, manufacturer and month.
The drug data have 20,646,523 reports that FDA received from January 2004 to June 2026. The device data have 26,326,888 reports that FDA received to September 2026. FDA publishes them through openFDA.
What the site is for
FDA publishes the reports as large data files. A reader cannot open them. This site counts the reports and shows each count with FDA's own words about the data.
- A patient or a carer can type a brand name and find the count of reports for each reaction term.
- A pharmacist, a clinician or a reporter can read the outcomes by year and download the counts as CSV files.
- A person who uses a device can read the event types by year, with FDA's statement about device counts.
What the site leaves out
- Advice. The site does not say what to take, or when to start, stop or change a medicine. A pharmacist or a clinician can say that.
- Rates. The data do not give the number of people who use a product, so a count is not a rate.
- Comparison. The site does not rank products or say that one product is safer than another. A table of several products is in order of name.
- Claims of cause. A report does not show that a product caused an event.
- People. The site shows no name of a patient or a reporter. It leaves out any name that reads as the name of a person.
- The text of reports. The openFDA files do not have it, and the site does not show it.
How the pages are made
A program makes the data pages from the FDA files. It uses fixed sentence rules. The same data always give the same text. No generative AI runs when the site is built.
The words of FDA are quotations. Each quotation names the FDA page that it comes from and the date on which the site read the page.
The sentence rules, the guides, the glossary and the pages about the site were written with an AI writing tool. Zippie is responsible for them. Each text page shows the date on which the site last checked it against FDA pages.
The page How the site counts reports gives the rules in full.
Funding
Zippie, the publisher, carries the cost of Reported Reactions. No page shows an advertisement now. Only the pages named in the methodology can carry advertising.
An advertisement on one of those pages would have a label. An advertiser cannot change a count, a sentence or the order of a list.
