What is norepinephrine (and what is it used for)?
Norepinephrine is a drug that acts on adrenergic receptors to raise blood pressure. Clinically, it is used to treat low blood pressure (shock), especially when the body’s circulation is failing and tighter control of blood pressure is needed.
What does norepinephrine do in the body?
Because norepinephrine is a “pressor” (it constricts blood vessels and increases vascular tone), it helps improve perfusion pressure—the pressure needed to deliver blood and oxygen to organs when the patient’s blood pressure is dangerously low.
Is norepinephrine the same as epinephrine?
No. Both are adrenergic (catecholamine) drugs, but they are not interchangeable. Their receptor activity differs, and dosing and clinical use can vary depending on the shock type and patient factors.
How is norepinephrine typically given?
Norepinephrine is usually administered by IV infusion in acute care settings where continuous blood-pressure monitoring is available.
What are common risks or side effects patients ask about?
Side effects and risks are often related to its blood-pressure–raising effects and increased vasoconstriction, which can include:
- Too-high blood pressure
- Reduced blood flow to peripheral tissues (from vasoconstriction)
- Tissue injury if medication leaks outside the vein during IV administration (extravasation risk)
Clinicians monitor blood pressure and perfusion closely and adjust the dose to balance effectiveness with safety.
