Chlamydia Psittaci,905,Killed + Feline Calicivirus,F-9,Live + Feline Panleukopenia Virus,Johnson Leopard Origin,Live + Feline Rhinotracheitis Virus,F2,Live Adverse Event Insights

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.
