Clos P*2/Cl Oth*5/H.Somnus Kb Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 13 adverse event reports referencing Clos P*2/Cl Oth*5/H.Somnus Kb, including 11 reports in which the animal died — a 8460.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Clos P*2/Cl Oth*5/H.Somnus Kb. Reported administration routes include Subcutaneous, 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 Clos P*2/Cl Oth*5/H.Somnus Kb reports are Cattle (13 reports), with Cattle accounting for the largest share. Within those species, Cattle (other) (5), Aberdeen Angus (4), Hereford cattle (2) 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*5/H.Somnus Kb are Death (8), Lack of efficacy - NOS (5), Lack of efficacy (bacteria) - NOS (3), NT - Abnormal necropsy finding NOS (2). Of the 26 reports with a coded outcome, Died is the leading category at 38.5%. 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 Clos P*2/Cl Oth*5/H.Somnus Kb.
