Ibuprofen: adverse event reports that FDA received

Active ingredient

The Green Book lists no brand name for exactly this active ingredient.

The openFDA records give the value "MSK" for the brand name and for the manufacturer name of each drug. FDA says that MSK means "masked". So the site cannot count a report for a brand.

Read this first. FDA says this about the data:

An API dataset query result cannot be used to estimate the risk associated with the product or compare one drug or device product with another. When looking at the results, be aware that there is no certainty that the reported drug or device caused the adverse event. This dataset should not be the sole source of information for clinical decision-making or other assumptions about the safety or effectiveness of a product. The adverse event may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources.

Contacting a veterinarianHow to report to FDA

From March 1997 to February 2026, FDA received 47 adverse event reports that name a drug with ibuprofen as its active ingredient. Of the 47 reports, 30 (63.8%) are about dogs. 16 reports are about people who were exposed to the drug (34%).

In January to March 2026, FDA received 1 report that names this drug. The signs that appear in the largest number of the 47 reports are "Vomiting" and "Accidental exposure". A report is not proof that a drug caused a sign.

Fewer than 20 reports named this drug in the 12 months before June 2026, so this page gives no change. Reports about dogs are 63.8% of the reports that name this drug, and 72.6% of all reports.

Search engines list a drug page with 500 reports or more in all years. The page also needs 30 reports or more in the 12 months to June 2026. This page is under one of these numbers. The site keeps the page and keeps it out of search engines.

Approved animal drugs with this active ingredient (FDA Green Book)

This section is reference data. It has no report count.

The openFDA records give the value "MSK" for the brand name and for the manufacturer name of each drug. FDA says that MSK means "masked". So the site cannot count a report for a brand.

The Green Book lists no approved animal drug with this active ingredient. FDA also receives reports for human drugs and compounded drugs that veterinarians prescribe.

Where the data come from

The counts come from the openFDA Animal and Veterinary adverse event files, export of 30 Oct 2026. The files have the reports that the FDA Center for Veterinary Medicine received through 26 Jun 2026. The files mask brand and manufacturer names. The site counts a drug by the active ingredients that each record gives, and gives no count to a brand, an application or a company. Ingredient names and the lists of approved products follow the FDA Green Book of 2 Nov 2026. The site does not use the application number that a record has.

The site does not publish report text, lot numbers or details of a reporter. FDA's record is the authority. See how the site counts reports, the data sources and the corrections page.
