Spironolactone Basics

Spironolactone treats congestive heart failure, edema, high blood pressure (hypertension), potassium deficiency, and hyperaldosteronism. It works by increasing the levels of water excretion by the kidneys.

This medication requires a prescription from your veterinarian and is available in 25mg and 50mg tablets.

Spironolactone Directions

Use as directed by your veterinarian and follow the instructions printed on the prescription label. Complete the entire prescription unless told otherwise by your veterinarian. Dosage and duration of treatment depend on the condition being treated and response to the medication. Be sure to give consistently in order to effectively manage symptoms. Also, give with food and water to lessen stomach upset.

Store at room temperature, protected from light and moisture.

Spironolactone Warnings

Keep out of the reach of children and pets. Spironolactone should not be used in animals with a known hypersensitivity or allergy to the drug. Do not use in animals that are pregnant or lactating, have high potassium levels in the blood, suffer from hypoadrenocorticism, or suffer from Cushing’s disease. Use caution when administering to animals with liver or kidney disease. Spironolactone may interact with some other medications. Therefore, it is important to inform your veterinarian of any and all medications your pet may be taking, especially mitotane. Spironolactone will cause your pet to urinate more frequently. If you notice any behavioral or physiological changes in your pet while administering Spironolactone, contact your veterinarian immediately.
