Aldazide (Spironolactone)

Aldazide is a diuretic, which means it causes you to pass out more urine from your kidneys. It helps your body to get rid of extra salt and water. It is used to lessen extra fluid in the body (called oedema) caused by conditions such as heart failure, or liver disease. This can reduce symptoms such as swelling in your ankles or feet, or shortness of breath. Aldazide is also used to treat high blood pressure (hypertension), and conditions in which the body is making too much of a natural chemical called aldosterone. Aldazide is available as tablets.

Aldazide is used in combination with other medicines to treat high blood pressure (hypertension) and heart failure. Lowering blood pressure can reduce the risk of strokes and heart attacks. Aldazide is also used to lessen the need for hospitalization for heart failure.

Aldazide is also used to diagnose and treat hyperaldosteronism, a condition in which the adrenal gland produces too much hormone called aldosterone. This medicine may also be used to treat fluid retention (edema) in patients with congestive heart failure, liver cirrhosis, or a kidney disorder called nephrotic syndrome.

Aldazide is a potassium-sparing diuretic (water pill). It prevents your body from absorbing too much salt and keeps your potassium levels from getting too low. This medicine is also used to treat or prevent hypokalemia (low potassium levels in the blood).

This medicine is available only with your doctor’s prescription.
