panacur — FDA Animal & Veterinary ADE Reports by Species (Dog vs Cat)
Source: openFDA animalandveterinary/event.json, the FDA Center for Veterinary Medicine (CVM) adverse event report database. Data pulled 2026-08-16. Counts are report-level: one report may list multiple reactions and multiple animals, so figures are not additive and do not imply causation. "Serious" follows the FDA serious_ae flag. Species values are as filed in each report. The Dog and Cat figures below are subsets of this drug's overall report total and do not necessarily sum to it (other species and reports with no species listed are excluded).

Honest scope note
This topic is a species cross-section of an existing per-drug ADE topic. Figures are aggregates of spontaneously reported adverse events and reflect reporting volume, not incidence or risk per animal treated. "Lack of efficacy" and similar terms denote product-performance reports, not adverse reactions.
