Thiabendazole + Dexamethasone + Neomycin Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 139 adverse event reports referencing Thiabendazole + Dexamethasone + Neomycin, including 8 reports in which the animal died — a 580.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Thiabendazole + Dexamethasone + Neomycin. Reported administration routes include Auricular (Otic), Unknown, Topical, Oral. 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 Thiabendazole + Dexamethasone + Neomycin reports are Dog (85 reports), Cat (53 reports), Ferret (1 reports), with Dog accounting for the largest share. Within those species, Domestic Shorthair (28), Retriever - Golden (7), Domestic Longhair (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 Thiabendazole + Dexamethasone + Neomycin are Emesis (31), Vomiting (21), Lethargy (see also Central nervous system depression in 'Neurological') (20), Behavioural disorder NOS (14). Of the 139 reports with a coded outcome, Recovered/Normal is the leading category at 43.2%. 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 Thiabendazole + Dexamethasone + Neomycin.
