How Does Furosemide Work?
Furosemide is a diuretic, which is commonly referred to as a “water pill.” Specifically, furosemide is known as a “loop diuretic,” named after the part of the kidneys that it affects (the loop of Henle). It works by increasing the amount of salt and water the kidneys remove from the blood. This extra salt and water is passed out through the urine. By increasing the amount of water removed from the blood, furosemide causes a decrease in blood volume. Because of this effect, furosemide can lower blood pressure and can also help with water retention.
