Ivermectin Pyrantel Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 13 adverse event reports referencing Ivermectin Pyrantel, including 0 reports in which the animal died — a 0.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Ivermectin Pyrantel. Reported administration route is 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 Ivermectin Pyrantel reports are Dog (13 reports), with Dog accounting for the largest share. Within those species, Spaniel - King Charles Cavalier (2), Spaniel - Cocker English (1), Terrier (unspecified) (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 Ivermectin Pyrantel are Medication error NOS (3), Vomiting (2), Decreased appetite (2), Diarrhoea (2). Of the 13 reports with a coded outcome, Ongoing is the leading category at 53.8%. 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 Ivermectin Pyrantel.
