About Aldactone
Aldactone contains spironolactone. Its medication class is potassium-sparing diuretic and aldosterone antagonist. It may be used for high blood pressure, heart failure or fluid retention and selected hormone-related concerns when a clinician considers it appropriate, depending on the exact product, diagnosis and the person’s health profile. It blocks aldosterone, helping the kidneys remove sodium and water while retaining potassium.
Whether Aldactone is appropriate depends on the diagnosis, exact product and strength, health history, other medicines and available follow-up. A general guide cannot determine whether this treatment is right for you.
