Calculi Reaction Insights

193 reports name Calculi; 50 recorded a death outcome (25.9% of reported events, not a population-level mortality rate). VeDDRA code: 741.

By species: Dog (140 reports), Cat (48 reports), Cattle (3 reports). By breed: Shih Tzu (19), Domestic Shorthair (19), Domestic (unspecified) (11).

Most co-reported drugs: Trilostane (17 reports), Cyclosporine (15 reports), Oclacitinib Maleate (15 reports), Milbemycin Oxime + Spinosad (14 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.
