Amoxicillin Trihydrate/Clavulanic Acid Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 86 adverse event reports referencing Amoxicillin Trihydrate/Clavulanic Acid, including 10 reports in which the animal died — a 1160.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Amoxicillin Trihydrate/Clavulanic Acid. Reported administration routes include Oral, Unknown. 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 Trihydrate/Clavulanic Acid reports are Dog (52 reports), Cat (34 reports), with Dog accounting for the largest share. Within those species, Domestic Shorthair (20), Domestic Longhair (6), Retriever - Labrador (6) 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 Trihydrate/Clavulanic Acid are Lethargy (see also Central nervous system depression in 'Neurological') (19), Vomiting (16), Other abnormal test result NOS (15), Diarrhoea (12). Of the 85 reports with a coded outcome, Outcome Unknown is the leading category at 64.7%. 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 Amoxicillin Trihydrate/Clavulanic Acid.
