Neomycin Sulfate, Nystatin, Thiostrepton, Triamcinolone Acetonide: low death-coded share in the FDA AER row
Read these counts as reporting volume, not risk: per our methodology, a widely-prescribed drug will rack up more raw FDA reports in a given year than a rarely-used one at an identical true rate, so we recommend comparing within similar-exposure products rather than across the full 2025 catalog.
