Uses

Oedema of cardiac, pulmonary, hepatic or renal (including nephrotic syndrome) origin,
Peripheral oedema of mechanical obstruction or venous insufficiency.

Maintenance therapy of mild oedema of any origin.

Hypertension.

Dosage

 

Oedema


Initial dose: 40mg in the morning.
Maintenance dose: 20mg or 40mg on alternate days. This dose may be increased to 120mg daily in the case of resistant oedema. Higher doses may be used.

 

 

Hypertension


20mg to 40mg twice daily, titrated to response.
If no clinical response is seen at the higher dose, it is advisable to consider the addition of other hypertensive agents, rather than an increase in furosemide dosage.
 
As furosemide is eliminated more slowly in elderly patients the dose should be titrated to the minimum effective dose.
