Amoxicillin/Clavulanate: high report volume 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.

High-volume nationwide drug peers

Two openFDA-derived peer sets for Amoxicillin/Clavulanate, both floored at ≥50 reports so the neighborhoods stay in the advertised mass.
