1. What Aldactone is and what it is used for
Aldactone contains the active substance spironolactone. Spironolactone is a potassium-sparing, diuretic (diuretic) that affects the kidneys in such a way that more fluid (urine) is excreted through the body. In addition to the diuretic effect, spironolactone has a blood pressure-lowering effect.
Aldactone is used for various forms of morbid fluid retention ( edema ) and high blood pressure when other treatments have no effect or are insufficient. It is also used in increased production of the adrenal cortex hormone aldosterone (primary aldosteronism) where other therapies are insufficient or inappropriate.
Children should only be treated by a pediatrician.
