Immune mediated haemolytic anaemia Reaction Insights

1,395 reports name Immune mediated haemolytic anaemia; 515 recorded a death outcome (36.9% of reported events, not a population-level mortality rate). VeDDRA code: 1896.

By species: Dog (1,277 reports), Cat (114 reports), Horse (4 reports). By breed: Retriever - Labrador (106), Crossbred Canine/dog (104), Shih Tzu (71).

Most co-reported drugs: Moxidectin (243 reports), Carprofen (146 reports), Prednisone (125 reports), Maropitant Citrate (120 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.
