Adrenaline

A substance produced by the Adrenal Glands, which prepares the body for fight or flight. It increases blood pressure, the heart rate, and nervous activity. Local anaesthetics contain adrenaline in very small quantities. Some patients are sensitive to adrenaline and it can induce a very rapid heart rate and palpitations. Dentists should be informed of any allergies/sensitivities.
