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.
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Tell your caregivers at once if you have any of these serious side effects:
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.
Before receiving norepinephrine, tell your doctor if you have high blood pressure (hypertension), overactive thyroid, asthma, or a sulfite allergy.
Tell your caregivers right away about any serious side effects such as muscle pain or weakness, numb or cold feeling, trouble breathing, urinating less than usual, irritation of the skin or vein where the medicine is injected, uneven heart rate, sudden numbness or weakness, especially on one side of the body, or sudden headache, confusion, or problems with vision, speech, or balance.
Symptoms of a norepinephrine overdose may include slow heart rate, severe headache, blurred vision, trouble concentrating, increased sensitivity to light, stabbing chest or back pain, pale skin, sweating, vomiting, or seizure (convulsions).
