Furosimide is the most commonly used diuretic in the horse. It increases urine production and decreases the amount of fluid within tissues and organs of the horse's body. It also acts upon the kidneys, causing increased excretion of electrolytes and water.
Furosemide is used to treat pulmonary edema, some allergic reactions, and congestive heart failure. Some veterinarians prescribe furosemide for racehorses because it is thought to prevent or diminish the severity of exercise-induced pulmonary hemorrhage or bleeding from the lungs. This use is controversial.
