Vetmedin® Chewable Tablets
Pimobendan is a cardiac drug used to treat dogs with congestive heart failure. Pimobendan helps strengthen the heart's muscular contractions and dilates the blood vessels. Pimobendan is offered as oblong, half-scored chewable tablets in two sizes (1.25 mg and 5 mg).
- A cardiac drug (inodilator) given by mouth
- Pimobendan opens the blood vessels that take blood away from the heart, thereby reducing the work the heart does to pump blood. Pimobendan also opens the blood vessels which return blood to the heart, reducing pressure on the heart
- Often used in conjunction with other drugs
- Used to manage the signs of mild, moderate or severe congestive heart failure in dogs 6 months of age or older due to atrioventricular valvular insufficiency (AVVI) or dilated cardiomyopathy (DCM)
- Increases the ability of the heart to pump blood more efficiently
- Pets with hypertrophic cardiomyopathy, aortic stenosis, or any other condition where an increase in cardiac output is not recommended
- Safety has not been evaluated in dogs less than 6 months of age, those with congenital heart defects, dogs with diabetes or other serious metabolic diseases, dogs used for breeding or pregnant or nursing dogs
- Synthetic beef flavor is actually derived from pork. Use with caution in pets allergic to pork
- If your pet has had an allergic reaction to pimobendan or like products
