Treats pulmonary edema, inflammation of the brain or for high blood pressure

Lasix is used to treat high blood pressure or fluid retention (swelling) associated with congestive heart failure, liver disease, or kidney disease. Lasix is a loop diuretic. Loop diuretics cause the kidneys to excrete larger amounts of electrolytes (especially sodium and potassium salts) and water than normal (diuretic effect). Loop diuretics are useful in treating many conditions in which salt and water retention (eg, edema, swelling) are a problem.
