About This Item

  • A compounded veterinary oral suspension containing spironolactone (25 mg/mL), commonly prescribed by veterinarians to help manage fluid retention (edema and ascites) related to congestive heart failure and hyperaldosteronism in dogs and cats.
  • Spironolactone

What is spironolactone used for in dogs and cats?

Spironolactone is commonly prescribed to help manage fluid buildup (edema or ascites) associated with congestive heart failure and conditions involving excess aldosterone, such as hyperaldosteronism, in dogs and cats.

How do I give this spironolactone suspension to my pet?

Shake the bottle well before each dose and measure the prescribed amount with an accurate dosing syringe. Administer orally as directed by your veterinarian and do not change the dose without their guidance.

How soon will I see improvement after starting spironolactone?

Some pets may show gradual improvement in fluid retention over several days, but the timeline varies by individual and underlying condition. Follow your veterinarian’s plan and attend recommended rechecks to assess response.

What side effects should I watch for?

Possible effects can include decreased appetite, vomiting, diarrhea, or lethargy. Because spironolactone affects electrolytes, changes in potassium can occur—contact your veterinarian if you notice weakness, collapse, or persistent gastrointestinal upset. Periodic bloodwork may be recommended.

Can spironolactone be given with other heart medications?

Yes, it is often used along with other cardiac therapies, but interactions are possible—especially with ACE inhibitors, ARBs, NSAIDs, or potassium supplements. Provide your veterinarian with a full list of all medications and supplements your pet takes.

What if I miss a dose?

Give the missed dose when you remember unless it is close to the next scheduled dose. If it is near the next dose, skip the missed dose and resume the regular schedule. Do not double up doses.

How should I store the spironolactone suspension?

Store according to the label directions and keep the cap tightly closed. Shake well before each use and keep out of reach of children and other animals. Do not use past the beyond-use date.
