What Is Lasix?

Lasix is a diuretic that helps to remove excess fluid from the body and relieve swelling. The main ingredient is furosemide, which is fast-acting, with a diuretic effect that begins already after 1 hour. This drug must necessarily be assigned by a doctor, taking into account the individual characteristics of the organism (heart, liver, adrenal glands, hormonal background (especially cortisone).
