Lasix, or furosemide, is a powerful diuretic. It works by preventing your kidneys from reabsorbing sodium and water. This increased excretion of sodium and water leads to a decrease in blood volume and blood pressure.
How it affects the body:
Specifically, Lasix inhibits the sodium-potassium-chloride cotransporter in the loop of Henle in your kidneys. This mechanism is responsible for a significant portion of sodium and water reabsorption. By blocking this transporter, Lasix forces your body to excrete more salt and water, resulting in increased urine production.
When is Lasix prescribed?
Doctors prescribe Lasix for various conditions, including edema (fluid retention) associated with congestive heart failure, liver disease, and kidney disease. It’s also used to treat high blood pressure and hypercalcemia (high blood calcium levels).
Important Considerations:
Lasix can cause side effects, including dehydration, dizziness, and electrolyte imbalances. Regular monitoring of potassium levels is typically necessary. Always follow your doctor’s instructions carefully and inform them about all other medications you are taking before starting Lasix.
