Liver Supplement Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 116 adverse event reports referencing Liver Supplement, including 9 reports in which the animal died — a 780.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Liver Supplement. Reported administration routes include Oral, Unknown, 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 Liver Supplement reports are Dog (106 reports), Cat (9 reports), Horse (1 reports), with Dog accounting for the largest share. Within those species, Retriever - Labrador (10), Chihuahua (7), Dog (unknown) (7) 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 Liver Supplement are Vomiting (23), Diarrhoea (22), Elevated alanine aminotransferase (ALT) (19), Lethargy (see also Central nervous system depression in Neurological) (16). Of the 117 reports with a coded outcome, Outcome Unknown is the leading category at 35.9%. 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 Liver Supplement.
