Omeprazole 37% Oral Paste Adverse Event Insights

The FDA Center for Veterinary Medicine database currently holds 412 adverse event reports referencing Omeprazole 37% Oral Paste, including 10 reports in which the animal died — a 240.0% case-fatality figure among reported events only, not a population-level mortality rate. Active ingredient on file: Omeprazole 37% Oral Paste. Reported administration routes include Oral, Unknown, Other, 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 Omeprazole 37% Oral Paste reports are Horse (226 reports), Unknown (179 reports), Human (4 reports), with Horse accounting for the largest share. Within those species, Unknown (184), Horse (unknown) (58), Thoroughbred (42) 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 Omeprazole 37% Oral Paste are INEFFECTIVE, GASTRIC ULCER(S) (171), Uncoded sign (96), Gastric ulcer (90), Locking Mechanism Abnormal (80). Of the 234 reports with a coded outcome, Outcome Unknown is the leading category at 65.0%. 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 Omeprazole 37% Oral Paste.
