Most co-reported drugs: Milbemycin Oxime + Spinosad (63 reports), Monensin Sodium (33 reports), Spinosad (32 reports), Fluralaner Chew Tablets (26 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.
