How it works
Lasix (Furosemide) is a loop diuretic (water pill). It works in the kidneys to make you urinate more, which removes extra water and certain electrolytes. This lowers blood pressure and swelling.Digoxin helps your heart work more efficiently. It makes your heart pump slower and stronger, which helps it get more blood and oxygen out to your body and organs.
