Spironolactone 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. . Spironolactone requires a prescription from your veterinarian.


Give this medication exactly as directed by your veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Spironolactone should be taken with food to lessen stomach upset. Keep plenty of water available for your pet. Do not suddenly stop giving this medication. Stopping suddenly could make the condition worse.


If any of the following serious side effects occur, stop giving spironolactone and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives); an irregular heartbeat, shortness of breath, fatigue, confusion, weakness, numbness, or decreased urination. Other less serious side effects may occur. Continue giving spironolactone and talk to your veterinarian if your pet experiences headache, dizziness, nausea, diarrhea, decreased appetite, or dry mouth. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to the animal.


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. Store spironolactone at room temperature, away from moisture and heat. Keep this medication away from children and pets.
