Fanconi syndrome Reaction Insights

19 reports name Fanconi syndrome; 2 recorded a death outcome (10.5% of reported events, not a population-level mortality rate). VeDDRA code: 2125.

By species: Dog (18 reports), Cat (1 reports). By breed: Retriever - Labrador (5), Shepherd Dog - German (2), Doberman Pinscher (2).

Most co-reported drugs: Carprofen (3 reports), Rabacfosadine Succinate (3 reports), Maropitant Citrate (2 reports), Milbemycin Oxime + Spinosad (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.
