DCM Medications
Common medications prescribed for dogs with Dilated Cardiomyopathy. Always follow your veterinarian's dosing instructions.
Vetmedin (Pimobendan)
Inodilator (positive inotrope + vasodilator)
The most commonly prescribed medication for dogs with DCM. Vetmedin strengthens the heart's contractions while reducing the workload on the heart.
$30–80/month depending on dog size and pharmacy. Generic pimobendan is often significantly cheaper than brand-name Vetmedin.
Betapace (Sotalol)
Class III antiarrhythmic / Beta-blocker
An antiarrhythmic medication used to control dangerous heart rhythm abnormalities (arrhythmias) in dogs with DCM, particularly ventricular premature complexes (VPCs).
$15–50/month. Generic sotalol is widely available and relatively affordable.
Lasix (Furosemide)
Loop diuretic
A powerful diuretic used to remove excess fluid from the body when DCM has progressed to congestive heart failure. Essential for managing fluid in the lungs or abdomen.
$5–20/month. One of the most affordable cardiac medications. Widely available as a generic.
Fortekor (Benazepril)
ACE inhibitor (angiotensin-converting enzyme inhibitor)
An ACE inhibitor commonly prescribed to reduce cardiac workload in dogs with DCM. By relaxing blood vessels, benazepril makes it easier for a weakened heart to pump blood effectively.
$15–40/month. Available as a generic, which is typically more affordable than brand-name Fortekor.
Enacard (Enalapril)
ACE inhibitor (angiotensin-converting enzyme inhibitor)
An ACE inhibitor used to reduce cardiac workload and manage heart failure symptoms in dogs with DCM. Enalapril works similarly to benazepril but is typically given twice daily for more consistent blood levels throughout the day.
$10–30/month. One of the most affordable ACE inhibitors. Widely available as a generic.
Aldactone (Spironolactone)
Potassium-sparing diuretic / Aldosterone antagonist
A gentle diuretic that works alongside furosemide to provide additional fluid removal while protecting against potassium loss. Spironolactone also blocks aldosterone, a hormone that contributes to harmful heart remodeling in DCM.
$15–35/month. Available as a generic tablet. Some veterinary pharmacies also carry combination tablets with hydrochlorothiazide, but the plain spironolactone is typically used for cardiac patients.
Mexitil (Mexiletine)
Class IB antiarrhythmic
An antiarrhythmic medication frequently used in combination with sotalol to control severe or treatment-resistant ventricular arrhythmias in Dobermans with DCM. Mexiletine targets a different part of the heart's electrical system than sotalol, making the two drugs especially effective together.
$30–80/month. Mexiletine can be one of the more expensive cardiac medications, and cost varies significantly between pharmacies. Compounding pharmacies may offer more affordable options — ask your vet about this.
Supplements
These are not medications but are commonly used alongside prescribed treatment. Supplements are not regulated to the same standard as pharmaceuticals. Always discuss with your vet before adding any supplement to your dog's regimen.
Taurine
Amino acid — may support cardiac function
L-Carnitine
Amino acid — involved in energy metabolism
CoQ10
Antioxidant — supports cellular energy production
Fish Oil (Omega-3)
Anti-inflammatory — EPA/DHA fatty acids
Supplements are not a substitute for prescribed medication. They should only be used under veterinary guidance as part of a complete treatment plan.
