kidneys to reduce the amount of sodium and water taken
back into the bloodstream, thus increasing the volume of
urine produced.
• Furosemide is used to treat oedema (fluid retention) caused
by heart failure, and certain liver and kidney disorders.

the body produces an abnormally small amount of urine, due
to kidney disease.
