Furosemide is used to treat fluid retention associated with conditions such as congestive heart failure, liver diseases such as acute hepatitis or cirrhosis, and kidney diseases, including nephrotic syndrome. It is also used to treat high blood pressure when it is necessary to reduce the amount of excess fluid in the body.
Furosemide works as a loop diuretic, which helps the body get rid of excess water and salts by increasing urine production, thus contributing to reducing pressure on the blood vessels and improving blood circulation. It should be used under medical supervision to avoid complications such as the loss of important minerals from the body.
