Vetmedin is a pet medication containing Pimobendan which can open up the main blood vessels to the heart to reduce blood pressure and is commonly used to treat heart failure in dogs. It can also make the heart work more efficiently and clinical studies indicate that this can increase life expectancy. Dogs may need to take this medication for the rest of their lives, though improvements can usually be seen in a few days. Vetmedin medication is available in different strengths for different sized animals and is in the form of chewable tablets — making it is easy to administer. Browse more prescription medications.

Vetmedin is used mostly in dogs with defective heart valves (valvular insufficiency or regurgitation, often as a result of nodular endocardiosis). If the valves in the heart fail to operate properly, blood flows back when the valves are supposed to be closed, making the heart less efficient as a pump. This also makes a whooshing sound in the heart, called a heart murmur, which vets can hear using a stethoscope. Vetmedin acts on the muscle of the heart and of blood vessel walls, helping the heart to beat more efficiently.

Vetmedin is also used to treat heart problems where the muscle has become stretched and weak (dilated cardiomyopathy). The heart muscle can contract more powerfully, improving circulation to the body tissues. This medication can be used on its own, but usually one or more other drugs are used to add to increase the beneficial effects.

Vetmedin is not suitable for dogs under the age of six months and should not be given to pregnant or nursing dogs. Care should also be taken with animals suffering from conditions such as diabetes and who are already taking other medications. Your vet will be able to determine if there is a risk of interactions with any other pet medication.

Vetmedin can only be obtained with a prescription from the vet. Buying prescription pet meds online still requires a written prescription, which must be sent with the order before the drugs can be supplied.

Having taken my dog Charlie back to the vet for his check up after being on vetmedin she was so pleased with him that he's not to be seen for six months... I think this speaks for the product Charlie has to take for life.

Most important empty stomach or 12 hours between?

john moss

Is it best to give thr tablets 12 hours apart or must it be an hour before food?

  • VioVet Staff

According to the datasheet this medication should be given every 12 hours, at least 1 hour before food (on an empty stomach). If you cannot do one or the other then you should contact your vet so they can advise which you should prioritise.

Break tablet in half?


  • VioVet customer since 2021
  • From: Hong Kong Island, Hong Kong

My dog takes 2.5mg of Vetmedin per dose, twice a day. Can I order the 5mg tablet version and break it in half? That would be more affordable than ordering the 1.25mg tablet. He'll be taking this for the rest of his life, so the money saved adds up over time. The 2.5mg tablets I'm currently using are easy to break and sometimes when I pop them out of the blister pack they break in half on their own. If the 5mg are of similar design, halving the dose would be very easy. Thank you!

  • VioVet Staff

Yes the Vetmedin tablets can be divided in half, they are scored on both sides to allow easy division. You will need to discuss with your vet whether this is appropriate though as they will need to prescribe the different tablet size to you. If you order your medications with us then we will need a new written prescription for the different tablet size and dose.

Dog vomiting every week

Marlene Sale

15 yr old Jack Russell Holly is on 1.25mg Vetmedin twice a day for for Mitral valve disease. Holly has been on it for 4 months and it has worked wonders for her.Am just concerned because she seems to vomit bile up every week is absolutely fine after and still has a good appetite. Wondered if it would help reducing the Vetmedin to 1 a day?

  • VioVet Staff

I do not recommend reducing the Vetmedin below the dose as recommended by your vet as the medication may not work effectively if reduced. If the vomiting started very soon after the Vetmedin was started then I advise discussing this with your vet as it could be related. There can be many different causes to this though unrelated to the Vetmedin and it is worth ruling them out with your vet.

Ventmedin 1.25 capsules


hi just wondering if we can break the capsule and place the ingredients inside into some water and syringe to insert into our dogs mouth as she finds it hard to swallow it and we have a hard time getting it down her throat. which actually causes more stress to our dog.

  • VioVet Staff

Drugs are generally made in a capsule for a reason, which is usually to protect the active ingredient in the stomach acid so that it can reach the small intestine where it is absorbed. I would be concerned that the drug would not be as effective if you were to mix the powder with water and syringe it in. Vetmedin is available in a tablet form if you think that this would be easier (your vet would need to write a prescription for tablets not capsules for us to dispense these).

Change of dosage


My dog has been on vetmedin for 6 months now and last week the vet and I decided to cut the dosage down to 1 a day purely for fianacel reasons. She seems to be a more sleepy and lethargic I'm thinking she needs to go back on the second one again would you say so as well ?

  • VioVet Staff

This drug only persists in the body for a few hours and twice daily dosing is likely to be much better than once daily. Regardless of that you should always give it on an empty stomach and with no food for at least 30 minutes afterwards if possible, because it is not easily absorbed into the body and any food present will reduce this further, reducing its effect. I would suggest going for twice daily if possible. You might find that if you can do the empty stomach bit very well, you could reduce the amount of each dose slightly to make it cheaper. Other than that it might be possible to add some other heart treatments which work well alongside Vetmedin but are cheaper (frusemide and digoxin for example). You must talk to your vet about them and they can have some side effects, but again at a lowish dose they are beneficial and safe. They are much cheaper than Vetmedin.

Once started on vetmedin can you stop the treatment then restart or should it be given continuel without a break

  • VioVet Staff

Most dogs treated with this medication benefit significantly from from it. If the drug is then stopped, they lose this benefit and go back to approximately how they were before. The would not be expected to be worse off, but given the benefit they receive when on the drug, it would be a shame to take this away.

Using Vetmedin for heart trouble

Hayley Baines

I'm looking for some advice, my dog is currently on Vetmedin 5mg Flavour Tablets and have noticed that she seems to feel the cold as she sits and shivers just wondered if this was a side effect and also what other side effects could this medication cause? also reading the information leaflet it's advised that the tablet should be given half in the morning then the other half 12 hours later? Both an hr before food? however my vet has said one tablet half an hour before food so I am slightly confused as i don't want to be miss dosing my dog?

  • VioVet Staff

Vetmedin is a very safe drug. It is most likely that your dog feels the cold because she is getting a bit older and less robust. I would doubt if the Vetmedin is doing that.

It is usual to give Vetmedin twice daily. In fact most of the drug is passed out of the system in just a few hours, so twice a day makes a lot more sense. It is also not absorbed very well from the stomach if there is food there too. 30-60 minutes before feeding is often recommended, but closer to 60 would seem better if you can manage it. Vetmedin is possibly the most useful drug there is for many heart problems, so it is well worth getting right if you can. The amount given on each occasion is based on the weight of your dog. It is always best to ask your own vet about the precise amount to give, which should be decided after weighing your dog.

  • VioVet customer since 2013
  • From: VIC, Australia

Hi, with regards to the Fortekor and Vetmedin drugs i wanted to find out how long of a use by date they come with, as i need a minimum 12 month use by date.

  • VioVet Staff

We have a high turn over of these products and deliveries are received daily, so you should normally expect to receive a product with a good length expiry date. Our supplier will continue to deliver a particular batch to us until they have all been used up, so occasionally the date may be slightly shorter than you require. If you would like to place an order for a long-term supply, you are welcome to contact our customer service team who will be able to tell you the expiry dates of batches in stock at the time. At present (21/10/13) the shortest expiry date we have for these products is 01/2015.

Alternatively, if it is convenient, you can place a few smaller orders for the prescribed medication, as we keep your prescription details and number of medication on our system. Once a prescription is has been loaded by our staff, you can log in to your VioVet account and check your amount remaining in the "Prescriptions" section.
