Loop diuretics are necessary adjuncts in the medical therapy for heart failure when symptoms are due to sodium and water retention. They are the mainstay of diuretic therapy because they produce significantly more natriuresis than other diuretics, particularly in the setting of decreased glomerular rate. They provide symptomatic relief without prolonging life or altering disease course.

Loop diuretics have a tendency to cause hypokalemia and hypomagnesemia. Therefore, monitor electrolyte levels and replace as necessary.
