Deer Adverse Event Insights

The FDA Center for Veterinary Medicine database holds 15 adverse event reports for Deer, distributed across 3 distinct breeds currently tracked in the system. Of those reports, 8 involved a death outcome, producing a 53.3% case-fatality rate among reported events, which reflects reporting severity bias rather than true population mortality. These figures are aggregated directly from openFDA's Animal & Veterinary Adverse Events endpoint and update as new voluntary submissions flow through pet owners, veterinarians, and drug manufacturers.

The most frequently reported clinical signs for Deer are Death (4 reports), Death by euthanasia (3 reports), Bone nonunion, medical device (2 reports), Pain NOS (2 reports), with Death leading the reaction traffic at 4 submissions. On the product side, Moxidectin is the single most-referenced drug with 3 reports, followed by Device: Surgical Instruments (2), Eprinomectin (2), Monensin Sodium (2). This combination surfaces which therapeutic classes generate the most adverse event chatter for this species, a useful starting point when comparing Deer reporting patterns against other companion animals in the dataset.

Of the 15 Deer reports with a coded outcome, Died accounts for the largest share at 33.3%. Annual submission volume spans 2,014 to 2,025 reports across the 10 years on file, a range that reflects evolving owner awareness, veterinary reporting habits, and new product approvals rather than stable underlying incidence. The breed-level table below breaks these patterns down further, showing how the 3 tracked deer breeds compare on volume, deaths, and average age at report. As with all FDA adverse event data, correlation is the ceiling, causation requires clinical investigation beyond what these aggregates can provide.
