Spironolactone is used to treat fluid retention, which may be caused by liver disease, kidney problems or heart failure. Fluid retention occurs when fluid leaks out of your blood vessels, causing swelling in the tissues of your lungs, feet or ankles.
Spironolactone prevents the fluid building in your body by increasing the amount of urine your kidneys produce.
Spironolactone is one of a family of medicines called diuretics, sometimes known as “water tablets.”
Spironolactone is important because, unlike some other diuretics, it does not cause your body to lose potassium.
