The FDA Center for Veterinary Medicine database currently holds 1,522 adverse event reports referencing Fluralaner 5.46% 1-Month Chew, including 34 reports in which the animal died — a 220.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Fluralaner 5.46% 1-Month Chew. Reported administration routes include Oral, Unknown, Other, Topical. 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.

Within those species, Crossbred Canine/dog (481), Retriever - Labrador (121), Retriever - Golden (75) 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 Fluralaner 5.46% 1-Month Chew are Vomiting (416), Lack of efficacy (ectoparasite) - flea (217), Emesis (multiple) (139), Lack of efficacy (ectoparasite) - tick NOS (126). Of the 1,487 reports with a coded outcome, Ongoing is the leading category at 55.5%. 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 Fluralaner 5.46% 1-Month Chew.
