Potassium-sparing diuretics are commonly used to help reduce the amount of water in the body. Unlike some other diuretics, these medicines do not cause your body to lose potassium. Amiloride and spironolactone are also used to treat high blood pressure (hypertension).
It is essential to follow your doctor's instructions with regard to potassium and dietary changes. Extra potassium may not be needed. In some cases, too much potassium can be harmful. Potassium-sparing diuretics do not cause a loss of potassium from your body as some other diuretics do. Therefore, if you are taking this type of diuretic, it is not necessary for you to get extra potassium in your diet.
