Generalised weakness Reaction Insights

701 reports name Generalised weakness; 238 recorded a death outcome (34.0% of reported events, not a population-level mortality rate). VeDDRA code: 1496.

By species: Dog (585 reports), Cat (92 reports), Horse (12 reports). By breed: Retriever - Labrador (84), Domestic Shorthair (58), Crossbred Canine/dog (37).

Most co-reported drugs: Trilostane (106 reports), Bedinvetmab (59 reports), Carprofen (56 reports), Milbemycin Oxime + Spinosad (44 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.
