Active ingredient on file: Nystatin/Neomycin Sulfate/Thiostrepton/Triamcinolone Acetonide Ointment. Reported administration routes include Topical, Unknown, Auricular (Otic). 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 Nystatin/Neomycin Sulfate/Thiostrepton/Triamcinolone Acetonide Ointment reports are Dog (7 reports), Cat (6 reports), with Dog accounting for the largest share. Within those species, Domestic Shorthair (3), Domestic Longhair (1), Retriever - Labrador (1) 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 Nystatin/Neomycin Sulfate/Thiostrepton/Triamcinolone Acetonide Ointment are Application site alopecia (5), Application site scab (4), Application site erythema (4), Application site ulcer (4). Of the 13 reports with a coded outcome, Recovered/Normal is the leading category at 46.2%. 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 Nystatin/Neomycin Sulfate/Thiostrepton/Triamcinolone Acetonide Ointment.
