What is Spironolactone Compounded?

Spironolactone Compounded is a potassium sparing diuretic used in the treatment of congestive heart failure (CHF), edema and high blood pressure (hypertension). Spironolactone is also used to treat potassium deficiency and hyperaldosteronism. Compounding is beneficial in instances where a specific dosage is unavailable or in different forms to make it easier to dose your pet. Spironolactone requires a prescription from your veterinarian.


Cats and Dogs

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


Tell your veterinarian if your pet has kidney or liver disease, diabetes mellitus, high levels of potassium in the blood, or if your pet is being given a potassium supplement or an ACE inhibitor such as enalapril or lisinopril. Tell your veterinarian if your pet is pregnant or lactating. Spironolactone will cause your pet to urinate more often, and your pet may have more "accidents" and need to go outside or use the litter box more. Make sure that your pet eats and drinks well while taking spironolactone or the risk of side effects increases.

How to Use
  • Spironolactone Compounded is a water pill (potassium-sparing diuretic) available by prescription that is used to treat edema, high blood pressure, potassium deficiency, and hyperaldosteronism.
  • Spironolactone Compounded is not FDA approved for use in veterinary medicine; however, it is a commonly accepted practice for veterinarians to prescribe this medication for dogs and cats.
  • It is also used as an aid in controlling excited animals during examination, treatment, and grooming.

What is a Compounded Medication?

A compounded medication is the creation of a particular medication to fit the unique needs of a patient, including changing the form of the medication (e.g., from a solid pill to a liquid) for a variety reasons (e.g., to make it easier to take, to avoid a non-essential ingredient, to obtain the exact dose needed, adding favorite flavors).

If you are having difficulty giving your pet prescribed medication or need to find a discontinued medication, 1-800-PetMeds offers compounding services on select medications. We can prepare the following: (1) custom strength quantities of a medication (as capsules, liquid, chewable tablets, or transdermal (absorbed through the skin); (2) dosage forms to mask bitter or unpleasant taste (such as capsules or chewable tablets that can also be flavored); (3) dosage forms to make it easier to dose your pet such as a transdermal or liquid (that can also be flavored); and (4) discontinued products such as cisapride or DES.

Customer Reviews


Is spirolactone when compounded as a liquid flavored? If not, how do I add that request to the prescription for a cat?
