Fortekor is a medication which can be used on cats or dogs but for different ailments. For dogs it is a heart failure medication and in cats is used to treat kidney failure. Dogs that use the medication may have a significantly increased lifespan and cats will find they have an increased appetite and general quality of life. Fortekor works by improving and increasing blood flow throughout the body, essential in both heart and kidney problems.

Fortekor is a small tablet which can be administered on its own or with food for ease and is available in a number of strengths depending on the size of the animal.

There can be some side effects to the medication. Cats may put on weight while using the drug but this is a positive side effect as they may have suffered weight loss with a kidney condition in the first place. Some dogs have suffered fatigue and mild dizziness but no stronger side effects have been noted in animals using the medication. There is a possibility of interaction with other drugs, so animals already on medication should be regularly monitored by a vet.

Fortekor is a prescription-only medication, which means a vet must write a prescription for it. However, it is possible to buy pet drugs online and VioVet supplies discount pet medication. The drug can also be obtained from your veterinary surgeon but this is often the most expensive way of purchasing medication. The prescription must be obtained from the vet and sent to VioVet before you can be supplied with the drug.

My lovely chocolate Labrador age 8 has kidney disease. These tablets as prescribed by my vet seem to be stabilising his condition. Small tablets that mix in well with his feed. Approximately half the price that my vet charges for the same tablets. Thank you viovet

Q & A

Below are some recent questions we've received regarding Fortekor Tablets for Dogs & Cats, including answers from our team.

Cats breathing

Dave hale

My 16 year old cat has been on fortekor 2.5 milligram for about 8 weeks now and we’ve noticed his breathing has become irregular,the vet also has put him on a water tablets to remove water from his lungs

  • VioVet Staff

If your cat's breathing is irregular then this can be related to a heart or lung problem. I strongly advise following your vet's advice, the breathing problem is unlikely related to the Fortekor and is more likely related to the underlying cause. Especially if there is fluid in/around your cat's lungs.

We starting using this yesterday, with diuretics for congestive heart failure and liver function - drinking LOADS!
Now his heartbeat is visibley stronger but he's shattered and won't eat, trying to start a new prescription diet doesn't help. He has lost so much weight worried about the lack of calories he is getting.
Is this normal in the first few days?

  • VioVet Staff

This is not ideal. There is sometimes a problem if you start the Fortekor and diuretic at the same time. It can be best to stagger them and wait a few days between starting these two types of medication. Dehysdration is a risk, despite the great thrist, which will not help. I would consider adjusting the medication but you will have to talk to your own vet about this as I am not familiar enough with your dog to be able to advise better than that. Do contact your vet straight away.

Enalapril or Fortekor


  • VioVet customer since 2014
  • From: , Singapore

Actually i know both are ACE inhibitor. but what is the difference between them ? Why should i pick one over another? Can anyone elaborate? thank you so much!

  • VioVet Staff

They are indeed both ACE inhibitors which means that they work through the same sort of mechanism in the body. They are both prescription-only so your vet will choose which one to prescribe. The drugs are marginally different (Fortekor contains benazepril) but the consequence of any differences is unlikely to be significant for most dogs. Both are pro-drugs which are converted in the body to the active forms. With benazepril this active form undergoes hepatic excretion, a possible advantage in animals with renal failure, whereas with enalapril, the active form is more extensively cleared from the body by the kidneys. A potential build up in the body in dogs with poor kidney function is perhaps more likely.

Fortekor plus Vivitonin


  • VioVet customer since 2015
  • From: Argyll and Bute, United Kingdom

My 13 year old 20kg dog was prescribed Vivitonin 100mgx2 daily after a CVD attack. Later she was also put on Fortekor 5mg daily for a grade 4 murmur.

Are the two drugs compatible or are there any interactions or cautions?

With thanks

  • VioVet Staff

These two drugs are often used together and they should be fine. Other drugs may be added too if the heart problems gets worse and Vivitonin should be OK with all the usual choices.

Drug interactions


Hi my dog has been put on Fortekor 20mg Vetmedin 1.25mg and frusemide 20mg. Is it still safe for her to take Yumove tablets daily as this helps with her mobilty?

  • VioVet Staff

All these tablets, including Yumove, are often used together in older dogs and as far as we can tell, they are perfectly safe and effective given that way. I am sure you can include Yumove for her mobility.
