Cardalis Medium Dog Tablets 5mg/40mg

Cardalis is a brown, oblong shaped tablet for the treatment of congestive heart failure in dogs. They are supplied in 2.5mg/20mg, 5mg/40mg and 10mg/80mg tablets and can be sold in either individual tablets or packs of 30. The active ingredients are benazepril hydrochloride and spironolactone.

Cardalis combines both benazepril and spironolactone, which means only one treatment is required. By giving both these ingredients, owners with dogs suffering with heart failure are 3 times less likely to see any deterioration in health or death due to heart failure than giving just benazepril alone.

The tablets should be given with food, either mixed in with small amount of food before a meal or with the main meal. Do not use in dogs intended or used for breeding. Do not use during pregnancy and lactation.

This is a prescription item and will be sent once a valid prescription is received.
