Why did I receive VETMEDIN CHEW?

Because of a shortage in the supply of the FDA-approved VETMEDIN chewable tablets, the FDA is allowing temporary use of VETMEDIN CHEW in the United States.

Is VETMEDIN CHEW the same as VETMEDIN chewable tablets?

The active ingredient in VETMEDIN CHEW is pimobendan, just like in Vetmedin chewable tablets, the US-approved product.
Both VETMEDIN CHEW and VETMEDIN chewable tablets are brownish, oval tablets that are scored in half so that the tablet can be divided in two equal parts.
Both VETMEDIN CHEW and VETMEDIN chewable tablets manage the signs of congestive heart failure.
You will notice the instructions for use in the VETMEDIN CHEW packaging to be slightly different than the instructions for the VETMEDIN chewable tablets. However, both VETMEDIN CHEW and VETMEDIN chewable tablets contain the same amount of pimobendan and the dose should be same.

Talk to your veterinarian if you have any questions about your dog’s congestive heart failure and the use of VETMEDIN CHEW.

Are there differences between VETMEDIN CHEW and VETMEDIN chewable tablets?

Size – the VETMEDIN CHEW is smaller, about half the size of the FDA approved VETMEDIN chewable tablet.
Strength — VETMEDIN CHEW is not available in 2.5 mg strength. The number and strength of VETMEDIN CHEW administered may be different than for VETMEDIN chewable tablets.
Inactive ingredients – some of the additional ingredients that make up or hold the tablets together are different between the two.
Packaging – VETMEDIN CHEW is packaged in cardboard boxes containing blister cards with 10 individually sealed tablets per card. VETMEDIN chewable tablets are packaged in bottles.

How do I give VETMEDIN CHEW to my dog?

VETMEDIN CHEW should be given to your dog in their mouth (orally) twice a day, about 12 hours apart as directed by your veterinarian. VETMEDIN CHEW should be given about 1 hour before feeding. If you have any questions about administration, please contact your veterinarian.

If a tablet is divided and only a half tablet is given to your dog, the remaining half should be returned to the open blister pocket and placed back in the cardboard box for storage. The remaining half tablet should be used within 3 days after opening the blister.

If your dog vomits after being given VETMEDIN CHEW, please contact your veterinarian and unless directed otherwise, do not give additional tablets again until the next scheduled dose.

What are some of the possible side effects of VETMEDIN Chew?

VETMEDIN CHEW may cause side effects similar to those seen with VETMEDIN chewable tablets, even at the prescribed dose. Contact your veterinarian immediately if your dog develops a serious or concerning medical problem or side effect while taking VETMEDIN CHEW.

The most common side effects of pimobendan containing products administration are:

poor appetite
difficulty breathing or coughing
weakness or difficulty walking
a rise in heart rate

There are other side effects which may occur with either VETMEDIN CHEW or VETMEDIN chewable tablets. For a complete list, ask your veterinarian.

For the treatment of canine congestive heart failure originating from dilated cardiomyopathy or valvular insufficiency (mitral and/or tricuspid valve regurgitation). (See also section “Dosage, routes and method of administration”).

For the treatment of dilated cardiomyopathy in the preclinical stage (asymptomatic with an increase in left ventricular end-systolic and end-diastolic diameter) in Doberman Pinschers following echocardiographic diagnosis of cardiac disease (see section “Special warnings” and “Precautions for use in animals”).

For the treatment of dogs with myxomatous mitral valve disease (MMVD) in the preclinical stage (asymptomatic with a systolic mitral murmur and evidence of increased heart size) to delay the onset of clinical symptoms of heart failure (see section “Special warnings” and “Special precautions for use in animals”).


Do not use pimobendan in hypertrophic cardiomyopathies or in diseases in which an improvement in cardiac output cannot be achieved for functional or anatomical reasons (e.g. aortic stenosis).

Since pimobendan is metabolised mainly via the liver, it should not be used in dogs with severe impairment of liver function (see also section “Pregnancy and lactation”). Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
