Reduced growth rate Reaction Insights

42 reports name Reduced growth rate; 18 recorded a death outcome (42.9% of reported events, not a population-level mortality rate). VeDDRA code: 2188.

By species: Dog (15 reports), Cattle (13 reports), Pig (8 reports). By breed: Crossbred Porcine/Pig (6), Cattle (unknown) (5), Cattle (other) (4).

Most co-reported drugs: Monensin Sodium (8 reports), Narasin (6 reports), Milbemycin Oxime + Spinosad (4 reports), Cefovecin (4 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.
