NEOPLASM RUPTURE Reaction Insights

14 reports name NEOPLASM RUPTURE; 11 recorded a death outcome (78.6% of reported events, not a population-level mortality rate). VeDDRA code: 99940.

By species: Dog (13 reports), Cat (1 reports). By breed: Beagle (3), Spaniel - Cocker American (1), Shepherd Dog - German (1).

Most co-reported drugs: Spinosad (4 reports), Ivermectin (2 reports), Carprofen (2 reports), Afoxolaner (2 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.
