What is Norepinephrine?
Norepinephrine is similar to adrenaline. It works by constricting (narrowing) the blood vessels and increasing blood pressure and blood glucose (sugar) levels.
Norepinephrine is used to treat life-threatening low blood pressure (hypotension) that can occur with certain medical conditions or surgical procedures. This medication is often used during CPR (cardio-pulmonary resuscitation).
Norepinephrine may also be used for purposes other than those listed in this medication guide.
