    • What is this medication and its most common uses?

      Aldactone is a medicine used to treat high blood pressure, low blood potassium levels, and hyperaldosteronism (an increase in a hormone called aldosterone that can cause an increase in blood pressure). Aldactone is also used to treat fluid retention in people with congestive heart failure (a condition in which the heart cannot pump enough blood throughout the body), cirrhosis (scarring of the liver), or nephrotic syndrome (a kidney disorder in which too much protein is excreted into the urine). Aldactone may also be used to increase survival and reduce the need for hospitalization in people with heart failure.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Aldactone is a water pill and works by eliminating extra fluid and sodium (salt) from your body. Aldactone also helps to reduce the excessive loss of potassium from your body. This helps to lower your blood pressure and fluid retention.

      What are the beneficial effects of this medication and when should I begin to have results?

      What: By lowering your blood pressure, Aldactone may lower your risk of a stroke or a heart attack. Aldactone has also been shown to reduce the chance of death or hospitalization due to heart failure.

      When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. Though you may not feel an improvement or change in the way you feel, it is very important to keep taking your medicine as prescribed to keep your condition under control.

      How do I know it is working?

      You may notice a decrease in your blood pressure and fluid retention after you start taking Aldactone. Check your blood pressure regularly. Your healthcare provider will also check your blood pressure at every visit. Following an appropriate diet and exercise plan will also affect your blood pressure results.
