Used primarily in medical settings, it acts as a vasoconstrictor to control bleeding during surgical procedures, particularly in areas like the nose, throat, and uterus. It helps reduce blood flow by narrowing blood vessels, making it easier for surgeons to operate with minimal blood loss. Additionally, it is sometimes employed in the management of hypotension, especially in cases of spinal anesthesia, to stabilize blood pressure. Its application is carefully monitored due to its potent effects on vascular tone.
