Spironolactone is used to treat fluid retention and high blood pressure. It works as a diuretic by reducing the reabsorption of sodium and water in the kidneys without losing potassium. It helps in cases of heart failure and swelling of the legs and abdomen resulting from fluid accumulation inside the body. It is also used in some hormonal conditions such as polycystic ovary syndrome because it reduces the effect of the male hormone.
Spironolactone is taken under medical supervision to determine the appropriate dose according to the health condition. It should not be stopped without consulting a doctor to avoid sudden complications. It may cause an increase in potassium, so tests must be monitored regularly to obtain maximum benefit and safety during treatment.
