Lambda-Cyhalotrin/Pip But P-On Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 19 adverse event reports referencing Lambda-Cyhalotrin/Pip But P-On, including 14 reports in which the animal died — a 7370.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Lambda-Cyhalotrin/Pip But P-On. Reported administration routes include Topical, 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 Lambda-Cyhalotrin/Pip But P-On reports are Cattle (19 reports), with Cattle accounting for the largest share. Within those species, Crossbred Bovine/Cattle (6), Cattle (other) (6), Aberdeen Angus (3) 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 Lambda-Cyhalotrin/Pip But P-On are Death (12), Lack of efficacy - NOS (6), Lack of efficacy (bacteria) - NOS (2), Abortion (2). Of the 32 reports with a coded outcome, Died is the leading category at 43.8%. 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 Lambda-Cyhalotrin/Pip But P-On.
