Why it costs more at the vet
Ceva-branded combination, lifelong dispensing. The compounding into one tablet commands a premium at the vet, and online pharmacies often supply both components separately for less.

- Diarrhoea (occasional)

Common questions
- Can I split Cardalis into separate pills?
- You can take benazepril and spironolactone separately on prescription. Many owners save further by buying the components as generics.
- How long does my dog need to take it?
- Heart failure medication is lifelong. Stopping abruptly is dangerous - always consult the vet first.
