Furosemide Injection

Furosemide is a loop diuretic used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or a chronic kidney disorder such as nephrotic syndrome. Furosemide is also used to treat high blood pressure (hypertension).

Furosemide works by increasing the amount of urine the body makes, which helps reduce swelling and symptoms of fluid retention and helps lower high blood pressure. Furosemide tablets are sometimes called water pills as they increase how much you urinate.

Furosemide is also known as frusemide in some countries. Furosemide became an FDA-approved medicine on July 1, 1966, and is available as tablets (Lasix), oral liquid, a subcutaneous injection (Furoscix), and an intravenous solution.
