Application site bleeding Reaction Insights
The FDA Center for Veterinary Medicine database currently lists 507 adverse event reports that reference Application site bleeding as a reaction term, including 12 reports with a death outcome — a 240.0% case-fatality figure calculated across only those events where this reaction was coded. The reaction is indexed in the openFDA system under VeDDRA code 12, the standardized veterinary dictionary used to normalize clinical signs across submitters. Because reports are voluntary and often describe multiple concurrent signs per animal, the volume here reflects reporting intensity rather than true incidence in the broader pet population.
Application site bleeding appears most frequently in reports for Cat (382 reports), Dog (107 reports), Human (6 reports) — with Cat dominating at 382 entries. Within those species, the breeds most often named alongside this reaction are Domestic Shorthair (233), Domestic Longhair (36), Domestic Mediumhair (23). These distributions are influenced both by underlying breed popularity and by how veterinarians and owners code a given clinical sign, so they should be interpreted as a reporting fingerprint rather than a pure susceptibility ranking.
The drugs most commonly co-reported with Application site bleeding are Selamectin (146 reports), Selamectin;Sarolaner (95 reports), Imidacloprid + Moxidectin (63 reports), Fluralaner Spot-On Solution (38 reports), with Selamectin appearing alongside this reaction in 146 submissions. Co-reporting does not establish that any specific product caused the reaction — FDA CVM data captures temporal association only. The value of these aggregates is in flagging which therapeutic classes appear repeatedly alongside a given clinical sign, so owners and veterinarians can ask targeted questions about medications currently in use.
