What is spironolactone and how does it work?

Spironolactone (sold under the brand names Aldactone and Carospir) is a potassium-sparing diuretic, also called an aldosterone receptor antagonist or mineralocorticoid receptor antagonist. It blocks the hormone aldosterone, which helps your body remove extra fluid and sodium while holding on to potassium. This lowers blood pressure and reduces swelling without wasting potassium the way many other water pills do.

It is FDA-approved to help treat heart failure (NYHA class III-IV, as add-on therapy to reduce the risk of death and hospitalization), high blood pressure, and edema (fluid buildup) from cirrhosis, nephrotic syndrome, or heart failure. It is also used to diagnose and treat primary hyperaldosteronism and to help manage low potassium (hypokalemia). Because it also has anti-androgen activity, spironolactone is very commonly prescribed off-label in dermatology and women's health.

Spironolactone cost and savings without insurance

Spironolactone is available as an FDA-approved generic, which is why it is typically an affordable medication. Even so, the cash price is not the same everywhere. Two pharmacies on the same street can list very different prices for the exact same prescription, so comparing before you fill genuinely matters. There is no manufacturer copay savings card for spironolactone because it is a low-cost generic.

If you are paying without insurance, or your plan does not cover it well, a free Rx.com discount coupon may bring the cash price down. Rx.com compares spironolactone prices across more than 60,000 U.S. pharmacies so you can find a lower price near you. Enter your ZIP above to see today's price and print or text yourself the coupon to show your pharmacist. The brand versions, Aldactone and Carospir, generally cost more than the generic.

Spironolactone alternatives and related diuretics

Spironolactone is one of several water pills, and the right choice depends on your condition and how your body handles potassium. Only your prescriber can decide what fits you, but these related medicines are often discussed alongside it:

• Eplerenone - another aldosterone receptor antagonist, often chosen when spironolactone's hormonal side effects are a concern (note: spironolactone and eplerenone should not be combined).
• Amiloride and Triamterene - other potassium-sparing diuretics.
• Hydrochlorothiazide - a thiazide diuretic commonly used for high blood pressure.
• Furosemide - a stronger loop diuretic used for more significant fluid retention.

All of these are available as generics. You can compare prices for each on Rx.com to see which is most affordable at your pharmacy.

Safety, side effects, and important warnings

Spironolactone carries a boxed warning because it was shown to cause tumors in chronic rat toxicity studies; it should not be used unnecessarily. The main safety concern is hyperkalemia (high potassium), which can be serious or even life-threatening. The risk is higher if you have kidney problems, diabetes, are older, or take ACE inhibitors, ARBs, potassium supplements, or salt substitutes. Your provider will usually check your potassium and kidney function while you take it, and you should avoid potassium-rich salt substitutes.

Other possible effects include low sodium, dehydration, dizziness, breast tenderness or enlargement (gynecomastia, related to dose and how long you take it), and menstrual changes. Spironolactone should not be used if you have high potassium, Addison's disease, no urine output (anuria), significant kidney impairment, or if you take eplerenone, and it should be avoided in pregnancy. This is general information, not medical advice; talk with your doctor or pharmacist about your own situation and any medicines you take.
