Labels, Abnormal: in adverse event reports for animal drugs

Clinical sign, a VeDDRA term

In plain words: a product quality report, not a sign in an animal.

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 June 1997 to January 2026, FDA received 212 adverse event reports for animal drugs that list this sign. That is under 0.1% of the 1,357,245 reports that FDA received from January 1987 to March 2026. In the 12 months to March 2026, FDA received 16 reports that list this sign.

Of the 212 reports, 2.8% are about dogs. A report can list more than one sign and more than one drug. A report is not proof that a drug caused a sign.

Fewer than 50 reports listed this sign in the latest 12 months. The site keeps the page for its links and keeps it out of search engines.

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. A report can name more than one drug.

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.

The adverse event may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources.

Where the data come from

The counts come from the openFDA Animal and Veterinary adverse event files, export of 2 Oct 2026. The files have the reports that the FDA Center for Veterinary Medicine received through 31 Mar 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 1 Oct 2026. The site counts the different spellings of one VeDDRA term together.

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.
