Budesonide Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 174 adverse event reports referencing Budesonide, including 19 reports in which the animal died — a 1090.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Budesonide. Reported administration routes include Unknown, Oral, Respiratory (Inhalation). 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 Budesonide reports are Cat (88 reports), Dog (84 reports), Horse (1 reports), with Cat accounting for the largest share. Within those species, Domestic Shorthair (53), Retriever - Labrador (13), Shih Tzu (7) 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 Budesonide are Diarrhoea (38), Vomiting (33), Not eating (20), Lack of efficacy - NOS (19). Of the 174 reports with a coded outcome, Ongoing is the leading category at 42.0%. 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 Budesonide.
