Enalapril Maleate Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 476 adverse event reports referencing Enalapril Maleate, including 55 reports in which the animal died — a 1160.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Enalapril Maleate. Reported administration routes include Oral, Unknown, Ophthalmic, Other. 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 Enalapril Maleate reports are Dog (451 reports), Cat (20 reports), Human (4 reports), with Dog accounting for the largest share. Within those species, Chihuahua (46), Terrier - Yorkshire (29), Spaniel - King Charles Cavalier (28) 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 Enalapril Maleate are Vomiting (80), Lethargy (see also Central nervous system depression in 'Neurological') (72), Emesis (68), Diarrhoea (49). Of the 476 reports with a coded outcome, Recovered/Normal is the leading category at 36.1%. 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 Enalapril Maleate.
