Lasix (generic name: furosemide) is a type of diuretic (often called a “water pill”) that is used to treat fluid retention (edema) associated with conditions such as congestive heart failure, liver disease (cirrhosis), and kidney disease including nephrotic syndrome[1][2][3][5][6].
Lasix is also prescribed alone or in combination with other medicines to treat high blood pressure (hypertension), although it is not typically considered a first-line treatment for hypertension unless other conditions are present[1][2][3][5][6].
It works by acting on the kidneys to increase urine production, which helps remove excess fluid and sodium from the body[1][2][3][5]. This can help reduce swelling and fluid overload, and aid in blood pressure reduction.
