Key points

  • Dehydration and electrolyte imbalance are the main risks with furosemide; sudden hearing changes are a serious warning that needs urgent attention.
  • Furosemide appears combined with the potassium-sparing diuretic amiloride (sold as Frumil), which offsets some of the salt losses.

How does Furosemide work?

Furosemide acts on a specific part of the kidney called the loop of Henle, where it blocks the reabsorption of sodium and chloride. The result is a strong diuretic effect: the kidneys pass more salt and water into the urine, reducing the fluid volume that builds up in tissues and blood vessels. Because less fluid circulates, blood pressure falls and swelling eases. Furosemide sits in the Heart & Blood Pressure category for this reason.
