What is the most important information I should know about norepinephrine?

Tell your caregivers at once if you have a serious side effect such as cold feeling anywhere in your body, blue lips or fingernails, trouble breathing, urinating less than usual, irritation or skin changes where the medicine is injected, slow heart rate, sudden numbness or weakness, confusion, severe headache, or problems with vision, speech, or balance.

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 not listed in this medication guide.

What should I discuss with my health care provider before receiving norepinephrine?

If possible before you receive norepinephrine, tell your doctor if you have:

  • high blood pressure (hypertension);
  • diabetes;
  • coronary artery disease;
  • circulation problems;
  • varicose veins;
  • overactive thyroid; or
  • asthma or a sulfite allergy.

In an emergency situation it may not be possible to tell your caregivers about your health conditions. Make sure any doctor caring for you afterward knows you have received this medicine.

In an emergency situation it may not be possible before you are treated with norepinephrine to tell your caregivers if you are pregnant or breast feeding. Make sure any doctor caring for your pregnancy or your baby knows you have received this medication.

How is norepinephrine given?

Norepinephrine is injected into a vein through an IV. You will receive this injection in a hospital or emergency setting.

Norepinephrine is usually given for as long as needed until your body responds to the medication. Some people must receive norepinephrine for several days.

Your blood pressure, breathing, and other vital signs will be watched closely while you are receiving norepinephrine.

Tell your caregivers if you feel any pain, irritation, cold feeling, or other discomfort of your skin or veins where the medicine is injected. Norepinephrine can damage the skin or tissues around the injection site if the medication accidentally leaks out of the vein.

What happens if I miss a dose?

Since norepinephrine is given by a healthcare professional in an emergency setting, you are not likely to miss a dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

  • sudden numbness, weakness, or cold feeling anywhere in your body;
  • slow or uneven heart rate;
  • blue lips or fingernails, mottled skin;
