What is Lasix?

Lasix is a loop diuretic — commonly called a water pill — used to treat fluid retention (edema) caused by heart failure, liver disease, or kidney disease, as well as high blood pressure. It works by blocking sodium and chloride reabsorption in the kidneys, causing the body to excrete significantly more water and salt through urine. This rapid fluid removal reduces swelling, lowers blood pressure, and eases the strain on the heart and lungs. It works quickly — usually within an hour of taking it — and its effects last 6 to 8 hours.

Loop diuretic mechanism

Blocks the sodium-potassium-chloride transporter in the loop of Henle in the kidney, preventing the reabsorption of sodium and water and dramatically increasing urine output.

Rapid edema relief

Works within 30 to 60 minutes of dosing to mobilize excess fluid from tissues and the circulatory system — providing fast relief from swollen legs, ankles, and the pulmonary congestion associated with heart failure.

Blood pressure reduction

By reducing overall fluid volume in the circulatory system, Lasix lowers blood pressure and reduces the workload on the heart — particularly valuable when fluid overload is a contributing factor.
