10,755 reports in FDA's animal adverse event database list the term "Color, Abnormal" (a product quality report, not a sign in an animal): 0.8% of all reports. It is a VeDDRA term, chosen by the person who coded the report to match what was described.

344 reports listed it in the 12 months to March 2026, up 15% from 300 in the 12 months before. FDA posts reports quarterly with a delay of three to six months, so the newest months are incomplete and usually grow in later releases.

By active ingredient, the drugs named most often in those reports are amoxicillin, amoxicillin trihydrate + clavulanate potassium and ivermectin + pyrantel pamoate. That order mostly follows how many reports each has overall; the table gives the term's share within each drug's own reports as well.

1.9% of the reports concern dogs, 0.9% of the reports concern cats and 0.3% of the reports concern cattle. Of reports listing this term that state seriousness, 33.1% were classed as serious; 0.3% record a death or euthanasia among the outcomes.

Ordered by number of reports, which mostly tracks how many reports a drug has overall. Across the whole database the term appears in 0.8% of reports. A drug's presence in a report means the animal received it, not that it produced the sign; FDA states that these data cannot be used to compare one product with another. openFDA masks brand and manufacturer names in adverse event records, so the reports counted here cannot be attributed to a particular brand.

Questions about "Color, Abnormal"

What does "Color, Abnormal" mean in an adverse event report?

In plain language: a product quality report, not a sign in an animal. It is a VeDDRA dictionary term picked to code what the reporter described. The report's free-text description is not published by FDA and is not shown here.

Does a drug appearing here mean it produced this sign?

No such conclusion can be drawn. FDA states that "there is no certainty that the reported drug or device caused the adverse event" and that the event "may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources."

My animal shows this sign. What now?

This site cannot assess an animal. A veterinarian can; for an emergency, contact a veterinary emergency clinic. See the guide on when to call a vet.

Where this comes from. Counts are built from the openFDA Animal & Veterinary adverse event bulk files released 28 Sep 2026, which hold reports FDA's Center for Veterinary Medicine received through 31 Mar 2026. openFDA masks brand and manufacturer names in these files, so drugs are counted by the active ingredients each record discloses and no figure is attributed to a brand, application or company. Ingredient names, and the separate reference lists of approved products, follow the FDA Green Book as of 1 Oct 2026. Spelling variants of the same VeDDRA term (for example with and without a cross-reference note) are pooled. No report text, lot numbers or reporter details are published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
