Aldactone, an aldosterone inhibitor, is a potassium-sparing diuretic. This medication is used to treat patients with heart failure when systolic dysfunction is present.
Aldactone is usually prescribed to prevent heart failure symptoms from becoming worse. Aldactone protects the heart by blocking a certain chemical (aldosterone) in the body that causes salt and fluid build-up.
Drug therapy to lower blood pressure has been shown to reduce heart failure rates by 40%-60%.
Reducing blockages in the coronary arteries with anti-cholesterol drugs has been shown to reduce heart failure rates by 30%.
Early diagnosis and treatment of heart-valve abnormalities can prevent heart failure caused by chronic volume overload of the heart's left chamber.
When receiving aldactone, you may be given a low dose that does not provide enough diuretic effects by itself. Your doctor may prescribe another type of diuretic in addition to aldactone.
How Do I Take Aldactone?
Follow the label directions on how often to take this drug. If you are taking a single dose a day, you may wish to take it in the morning with your breakfast or right after eating your breakfast. If you are taking more than one dose a day, consider taking the last dose no later than 4 p.m so that you are not waking up late at night to urinate.
The number of doses you take each day, the time allowed between doses, and how long you need to take the medication will depend on your condition.
