The EpiPen is a medical device designed to deliver a single dose of adrenaline into the muscle during a severe allergic reaction known as anaphylaxis. It is used to treat symptoms like throat swelling, difficulty breathing and a sudden drop in blood pressure caused by exposure to allergens.
The primary active ingredient in this treatment is adrenaline, which is also referred to internationally as epinephrine. Adrenaline is a naturally occurring hormone that works rapidly to reverse the symptoms of a systemic allergic reaction by narrowing blood vessels and opening the airways.
Many users find the EpiPen reliable and easy to operate under pressure due to its clear instructions and ergonomic design. Patients often report feeling more secure carrying the device, knowing they have a fast-acting tool to manage accidental allergen exposure in everyday environments.
Every device is supplied with a comprehensive Patient Information Leaflet (PIL) that provides detailed instructions on use, storage and safety. You should read this document thoroughly to familiarise yourself with the specific requirements of your adrenaline auto-injector.
Adrenaline works by stimulating alpha and beta-adrenergic receptors in the body to counteract the physical effects of anaphylaxis. This process helps to increase blood pressure, reduce swelling and relax the muscles in the lungs to improve breathing during an emergency.
- Grasp the device in your dominant hand with your thumb closest to the blue safety cap.
- Pull the blue safety cap straight up to remove it.
- Hold the device at a right angle to your outer thigh.
- Jab the orange tip firmly into the thigh until it clicks and hold for 3 seconds.
- Remove the pen and massage the injection site for 10 seconds, then call 999 immediately.
The dosage is determined by the patient's body weight and is delivered as a pre-measured single dose. It is widely recommended that patients at risk of anaphylaxis carry two auto-injectors at all times in case a second dose is required before medical help arrives.
Common side effects following an injection of adrenaline may include:
- Increased heart rate or palpitations
- Tremors or shakiness
- Dizziness and headache
- Nausea or vomiting
- Anxiety or nervousness
You should only use the EpiPen in the outer thigh and never inject it into the buttocks, hands or feet. Inform your prescriber if you have a history of heart disease, high blood pressure or thyroid conditions, though in a life-threatening emergency, adrenaline remains the first-line treatment regardless of these factors.
