Cardalis Medium Dog Tablets 5mg/40mg

Cardalis is a brown, oblong shaped tablet and is 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 is a prescription item and will be sent once a valid prescription is received. Please follow the instructions given by your vet.

Congestive heart failure is when your dog's heart has trouble pumping blood to the rest of the body. This can be caused by old age, an injury or an infection. In some cases, dog's can be born with this defect.

Early symptoms can be:

. Coughing more than usual

. Tiring easily

. Hard time breathing

. Swollen belly

Why Cardalis? Cardalis is different to other medications as it 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.


2.5-5kg - 1/2 x 2.5mg/20mg tablet

5-10kg - 1 x 2.5mg/20mg

10-20kg - 1 x 5mg/40mg

20-40kg - 1 x 10mg/80mg

60-80kg - 2 x 10mg/80mg

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.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

Had the goods, the price and the 'free prescription'service. The latter was hassle free (after the receptionist was helped by a vet!)


Always a smooth transaction and the best value.


Competitive prices, easy ordering system and prompt delivery.


Had my doubts about ordering, wish I'd done it, years ago.


First class service. I use Pet Drugs on Line for prescription medicine for my dog. Always receive confirmation of dispatch either same day or next working day from order. Great customer service who resolved issue quickly; they even contacted me to check quantity of one tablet on order, as I had order 3 rather than 30.


Excellent Service!

Good, efficient service. Many thanks.


Having only just started my cat on the royal canin she is still getting used to it, she seems to like it, I would have liked to have had more flavours.

On 03 Dec 2016 Pet Drugs Online responded:
Dear Rosemary
Many thanks for your feedback,  glad to hear that your cat is getting used to the renal diet. Most cats do seem to like the renal food but some prefer certain flavours chicken being one of the favourites. Prescription diets aren't always the most palatable as they do a specific job and have not got any bad things which can make your pet eat them more readily, sometimes if you warm the food slightly that can make the food more palatable and this will also give off more aroma
Kind regards


Site very easy to use and delivery very prompt.Big savings on prescription drugs compared to vet prices.


The required medicine was easily found and ordered. Arrived promptly and in good order. Cheapest I could find and free shipping too.
