Unlike adrenaline, which affects several parts of the body, noradrenaline’s main role is to control blood pressure. It is made in the nervous system and released into the blood continuously. The body also produces a similar chemical called noradrenaline (or norepinephrine).
It makes you stronger and allows you to perform better. When you have a lot of adrenaline in your blood, you don’t feel as much pain, so you can keep running or fighting, even if you are injured. It causes the blood vessels to send more blood to the brain and muscles, increases your blood pressure, makes your brain more alert, and raises sugar levels in the blood to give you energy. What is the role of adrenaline?Īdrenaline makes your heart beat faster and your lungs breathe more efficiently.
If someone is having an anaphylaxis, give the adrenaline first then call triple zero (000) and ask for an ambulance. The dose can be given using an autoinjector, and you can read about how to use an adrenaline autoinjector here. You might still feel the effects of it though, for up to 1 hour. When the situation becomes calmer, the glands stop producing adrenaline. It may also be used during cardiac arrest, croup and asthma when other treatments are not effective.
You will feel the effects of the adrenaline within 2 or 3 minutes.Īdrenaline is also a medication used to treat a severe allergic reaction ( anaphylaxis) in an emergency. In this type of situation, your brain sends messages to your adrenal glands (located just above the kidneys) to start releasing the hormone into the blood. This is known as the ‘fight-or-flight response’.
