Norepinephrine — Uses, Dosage, Side Effects & Safety

Drug class: Vasopressor, Sympathomimetic

Overview

Norepinephrine is a medication used to treat life-threatening low blood pressure (hypotension), especially in situations such as septic shock or after major surgery. It works by narrowing blood vessels, which increases blood pressure and helps vital organs receive enough blood and oxygen. This medicine is usually given in a hospital setting through an intravenous (IV) line under close medical supervision. Norepinephrine acts quickly and is often used when other measures to raise blood pressure are not effective. Key points: Norepinephrine is not for self-administration and should only be used under the guidance of healthcare professionals. Patients and families should be aware of possible side effects and the need for continuous monitoring during treatment.
