Amoxicillin Trihydrate + Clavulanate Potassium Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 403 adverse event reports referencing Amoxicillin Trihydrate + Clavulanate Potassium, including 25 reports in which the animal died — a 620.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredients on file: Amoxicillin Trihydrate, Amoxicillin Trihydrate + Clavulanate Potassium, Clavulanate Potassium. Reported administration routes include Oral, Unknown, Auricular (Otic), Subcutaneous. 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 + Clavulanate Potassium reports are Dog (334 reports), Cat (69 reports), with Dog accounting for the largest share. Within those species, Domestic Shorthair (38), Retriever - Labrador (26), Terrier - Yorkshire (24) 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 + Clavulanate Potassium are Emesis (118), Vomiting (84), Lethargy (see also Central nervous system depression in 'Neurological') (61), Lack of efficacy - NOS (40). Of the 403 reports with a coded outcome, Recovered/Normal is the leading category at 52.1%. 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 + Clavulanate Potassium.
