Panleucopenia Reaction Insights

66 reports name Panleucopenia; 25 recorded a death outcome (37.9% of reported events, not a population-level mortality rate). VeDDRA code: 169.

By species: Dog (42 reports), Cat (23 reports), Other Canids (1 reports). By breed: Domestic Shorthair (13), Retriever - Labrador (8), Maltese (3).

Most co-reported drugs: Cefovecin (12 reports), Maropitant Citrate (12 reports), Oclacitinib Maleate (11 reports), Moxidectin (6 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.
