Prozinc Human Insulin Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 24 adverse event reports referencing Prozinc Human Insulin, including 6 reports in which the animal died — a 2500.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Prozinc Human Insulin. Reported administration routes include Subcutaneous, Unknown, 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 Prozinc Human Insulin reports are Cat (17 reports), Dog (7 reports), with Cat accounting for the largest share. Within those species, Domestic Shorthair (9), Domestic Longhair (4), Cat (unknown) (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 Prozinc Human Insulin are Lack of efficacy - NOS (15), Death by euthanasia (4), Lethargy (see also Central nervous system depression in Neurological) (3), INEFFECTIVE, GLYCEMIC CONTROL (3). Of the 24 reports with a coded outcome, Outcome Unknown is the leading category at 37.5%. 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 Prozinc Human Insulin.
