Furosemide is a diuretic, which means it helps your body get rid of extra salt (sodium) and water. It works by increasing the amount of urine (pee) you make. Furosemide is used to lessen extra fluid in the body (called oedema) caused by conditions such as heart failure, liver disease, or kidney disease. This can reduce symptoms such as swelling in your ankles or feet, or shortness of breath. Furosemide is also used to treat high blood pressure (hypertension).
In New Zealand furosemide is available as tablets and liquid and can be given as an injection in the hospital.
