Active ingredient on file: Flunixin Meglumine Injectable. Reported administration routes include Unknown, Intravenous, Intramuscular, Subcutaneous. These numbers reflect voluntary submissions from pet owners, veterinarians, and manufacturers and therefore under-represent mild events and over-represent severe ones — a pattern the FDA has documented repeatedly for pharmacovigilance datasets.

The species most frequently named in Flunixin Meglumine Injectable reports are Horse (120 reports), Cattle (78 reports), Unknown (49 reports), with Horse accounting for the largest share. Within those species, Unknown (74), Quarter Horse (37), Cattle (other) (21) appear most often — though breed popularity and ownership density shape these counts as much as any drug-specific sensitivity. This distribution matters because the same active ingredient can behave very differently across body sizes, ages, and species physiology.

The most commonly reported clinical signs associated with Flunixin Meglumine Injectable are Death (81), Lack of efficacy - NOS (48), Contamination, Particulate Matter (28), Injection site swelling (23). Of the 300 reports with a coded outcome, Died is the leading category at 30.7%. Because FDA adverse event data describes correlation rather than causation, these figures are best used to frame informed questions with a veterinarian and to compare reporting patterns across related products — not as a standalone safety verdict on Flunixin Meglumine Injectable.
