About This Item

  • A compounded oral capsule containing spironolactone, a potassium-sparing diuretic and aldosterone antagonist used to help manage fluid retention from congestive heart failure and aldosterone excess (e.g., feline hyperaldosteronism) in dogs and cats, in the specific strength prescribed by your veterinarian.
  • Spironolactone

What is spironolactone used for in dogs and cats?

Spironolactone is commonly prescribed to help manage fluid build-up (edema or ascites) associated with congestive heart failure, and to address aldosterone-related conditions such as feline hyperaldosteronism.

How do I choose the right strength to order?

Select the capsule strength that exactly matches your veterinarian’s prescription. Do not substitute strengths or change the dose unless your veterinarian advises it.

Can spironolactone be given with other heart medications?

Yes. Spironolactone is often used alongside other cardiac medications—such as diuretics or ACE inhibitors—when prescribed by a veterinarian as part of a comprehensive heart failure plan.

What side effects should I watch for?

Possible effects may include gastrointestinal upset (decreased appetite, vomiting), lethargy, or changes in thirst and urination. Because spironolactone is potassium-sparing, elevated potassium can occur; contact your veterinarian if you notice weakness, collapse, or any concerning changes.

Should I avoid potassium supplements or salt substitutes while my pet is on spironolactone?

Yes, do not give potassium supplements or salt substitutes unless specifically directed by your veterinarian, as spironolactone can increase potassium levels.

How soon will I see improvement?

Response varies by pet and condition. Your veterinarian will guide monitoring for breathing effort, coughing, activity level, and abdominal distension, and will adjust therapy if needed.
