Multi-Vitamin Adverse Event Insights
The FDA Center for Veterinary Medicine database currently holds 63 adverse event reports referencing Multi-Vitamin, including 28 reports in which the animal died — a 4440.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Multi-Vitamin. Reported administration routes include Unknown, Oral, Subcutaneous, Intramuscular. 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 Multi-Vitamin reports are Dog (37 reports), Cattle (23 reports), Cat (2 reports), with Dog accounting for the largest share. Within those species, Cattle (other) (9), Mixed (Cattle) (9), Retriever - Labrador (8) 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 Multi-Vitamin are Death (16), Lack of efficacy (bacteria) - NOS (12), Lethargy (see also Central nervous system depression in 'Neurological') (10), Lack of efficacy - NOS (9). Of the 86 reports with a coded outcome, Died is the leading category at 27.9%. 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 Multi-Vitamin.
