Low sodium-potassium ratio (Na:K ratio) Reaction Insights

1,069 reports name Low sodium-potassium ratio (Na:K ratio); 151 recorded a death outcome (14.1% of reported events, not a population-level mortality rate). VeDDRA code: 2630.

By species: Dog (1,014 reports), Cat (47 reports), Horse (8 reports). By breed: Chihuahua (69), Shih Tzu (58), Retriever - Labrador (52).

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.
