This medication is known as a diuretic (like a "water pill"). It helps your body get rid of extra water by increasing the amount of urine you make. Getting rid of extra water decreases the strain on your heart and blood vessels, thereby lowering high blood pressure and reducing your risk of strokes, heart attacks, and kidney problems. This effect can also improve symptoms such as trouble breathing and swelling (edema). This injectable form of furosemide is used when the drug cannot be taken by mouth, especially in patients with severe medical conditions.
This medication is given by injection into a muscle or slowly into a vein as directed by your doctor. The dosage is based on your age, medical condition, and response to treatment. In children, the dosage is also based on weight.
