from the body. Diuretics are also known as ‘water tablets’.
Furosemide tablets are used in the treatment of oedema (fluid retention)
caused by disorders of the heart, kidneys or liver alone or in combination
with other anti-hypertensive agents. The tablets may also be used to treat
pulmonary oedema (build up of fluid in the lungs) and mild to moderate
hypertension (high blood pressure).
