Hydrocodone/Homatropine Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 12 adverse event reports referencing Hydrocodone/Homatropine, including 1 reports in which the animal died — a 830.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Hydrocodone/Homatropine. Reported administration routes include Unknown, 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 Hydrocodone/Homatropine reports are Dog (12 reports), with Dog accounting for the largest share. Within those species, Crossbred Canine/dog (6), Maltese (3), Chihuahua (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 Hydrocodone/Homatropine are Cough (3), Diarrhoea (2), Vomiting (2), Excessive thirst (2). Of the 12 reports with a coded outcome, Recovered/Normal is the leading category at 66.7%. 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 Hydrocodone/Homatropine.
