Clos P*2/Cl Oth*4/Mor Bovis Kb Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 26 adverse event reports referencing Clos P*2/Cl Oth*4/Mor Bovis Kb, including 24 reports in which the animal died — a 9230.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Clos P*2/Cl Oth*4/Mor Bovis Kb. Reported administration route is 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 Clos P*2/Cl Oth*4/Mor Bovis Kb reports are Cattle (26 reports), with Cattle accounting for the largest share. Within those species, Crossbred Bovine/Cattle (9), Cattle (other) (9), Red Angus (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 Clos P*2/Cl Oth*4/Mor Bovis Kb are Death (20), Found dead (5), Lack of efficacy - NOS (5), Anaphylaxis (4). Of the 35 reports with a coded outcome, Died is the leading category at 68.6%. 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 Clos P*2/Cl Oth*4/Mor Bovis Kb.
