Physicians and Medical Practitioners in clinics, emergency rooms, and minor emergency centers have depended on injectable Lidocaine (Xylocaine) with Epi for use with patients requiring a local or regional anesthetic with epinephrine. While the lidocaine blocks the neural impulses to the CNS, the epinephrine reduces blood flow that subsequently prolongs the action of the lidocaine. Another benefit of Lidocaine w/epi is its vasoconstrictive properties that allow the physician to visualize lacerations while stitching.
