Product Info:

Spironolactone is available by prescription only. Spironolactone is used to treat congestive heart failure, edema, high blood pressure (hypertension), potassium deficiency, and hyperaldosteronism. Spironolactone works by increasing the levels of water excretion by the kidneys.


Cats and Dogs


  • Does not cause loss of potassium
  • Also used to treat edema and high blood pressure
  • Easy to administer

How it works:

Spironolactone inhibits the effect of aldosterone, a hormone that causes the tubules of the kidneys to retain sodium and water. This increases the excretion of water and sodium, while decreasing the excretion of potassium.


Store at room temperature away from moisture and heat.

  • Give Spironolactone with food to lessen stomach upset. Keep plenty of water available for your pet.
