Dinoprost Tromethamine Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 697 adverse event reports referencing Dinoprost Tromethamine, including 171 reports in which the animal died — a 2450.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Dinoprost Tromethamine. Reported administration routes include Intramuscular, Unknown, Subcutaneous, Topical. 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 Dinoprost Tromethamine reports are Cattle (511 reports), Unknown (65 reports), Human (63 reports), with Cattle accounting for the largest share. Within those species, Mixed (Cattle) (133), Unknown (128), Holstein-Friesian also known as Holstein (110) 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 Dinoprost Tromethamine are Lack of efficacy - NOS (234), INEFFECTIVE, ESTRUS SYNCHRONIZ (133), Death (126), Injection site swelling (87). Of the 678 reports with a coded outcome, Outcome Unknown 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 Dinoprost Tromethamine.
