Amoxicillin/Clavulanic Acid Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 102 adverse event reports referencing Amoxicillin/Clavulanic Acid, including 19 reports in which the animal died — a 1860.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Amoxicillin/Clavulanic Acid. Reported administration routes include Oral, Unknown, Topical, Parenteral. 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 Amoxicillin/Clavulanic Acid reports are Dog (76 reports), Cat (25 reports), Parrot (1 reports), with Dog accounting for the largest share. Within those species, Domestic Shorthair (18), Crossbred Canine/dog (9), Retriever - Labrador (8) 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 Amoxicillin/Clavulanic Acid are Vomiting (20), Lethargy (see also Central nervous system depression in 'Neurological') (16), Anorexia (15), Not eating (14). Of the 102 reports with a coded outcome, Outcome Unknown is the leading category at 37.3%. 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 Amoxicillin/Clavulanic Acid.
