Data pulled 2026-08-16. This topic covers adverse-event reports for the active ingredient **Prednisone** (queried as `drug.active_ingredients.name`). Overall report total for this ingredient: **9395**. 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 ingredient's overall report total and do not necessarily sum to it (other species and reports with no species listed are excluded).\n\n## Dog (8624 reports)\n- Serious adverse events (FDA `serious_ae` flag): 4498 (52.2% of 8624)\n- Top reported reactions (VEDDRA terms):\n  - Vomiting 1309\n  - Lethargy (see also Central nervous system depression in 'Neurological') 1077\n  - Diarrhoea 963\n  - Lack of efficacy - NOS 768\n  - Death by euthanasia 674\n## Cat (734 reports)\n- Serious adverse events (FDA `serious_ae` flag): 353 (48.1% of 734)\n- Top reported reactions (VEDDRA terms):\n  - Weight loss 98\n  - Vomiting 95\n  - Lethargy (see also Central nervous system depression in 'Neurological') 89\n  - Lack of efficacy - NOS 82\n  - Anorexia 81\n\n## Honest scope note\nThis topic is a species cross-section of FDA adverse-event reports for a single active ingredient, queried by `drug.active_ingredients.name`. 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. Different marketed presentations of the same compound (e.g. chewable vs spot-on) may be filed under distinct name strings in openFDA and are not merged here.
