Addison's disease Reaction Insights

305 reports name Addison's disease; 46 recorded a death outcome (15.1% of reported events, not a population-level mortality rate). VeDDRA code: 384.

By species: Dog (305 reports). By breed: Retriever - Labrador (31), Dog (unknown) (26), Terrier - Boston (16).

Most co-reported drugs: Trilostane (186 reports), Milbemycin Oxime + Spinosad (37 reports), Afoxolaner (18 reports), Oclacitinib Maleate (15 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.
