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.
