Scar Reaction Insights

78 reports name Scar; 3 recorded a death outcome (3.8% of reported events, not a population-level mortality rate). VeDDRA code: 2544.

By species: Dog (58 reports), Cat (10 reports), Horse (4 reports). By breed: Retriever - Golden (6), Domestic Shorthair (6), Retriever - Labrador (5).

Most co-reported drugs: Prednisone (28 reports), Tigilanol Tiglate (28 reports), Diphenhydramine (25 reports), Famotidine (25 reports).

Read these counts as reporting volume, not risk: per our methodology, co-reporting reflects temporal association captured in voluntary submissions, not proof that a drug caused this reaction. A widely-prescribed drug will rack up more raw co-reports at an identical true rate than a rarely-used one, so compare within similar-exposure products.
