TL;DR

Device for injecting adrenaline to treat severe allergic reactions like anaphylaxis.

What is an Epipen?

An Epipen is an auto-injector device used to administer a dose of epinephrine (adrenaline) in the event of a severe allergic reaction, known as anaphylaxis. Anaphylaxis can be triggered by various allergens, including food, insect stings, medications, and latex, leading to symptoms such as difficulty breathing, swelling, hives, and a drop in blood pressure.

The prompt administration of epinephrine can reverse these symptoms, improving breathing, reducing swelling, and stabilizing blood pressure. It is a life-saving intervention that must be administered quickly when signs of anaphylaxis are present.

To use an Epipen, remove it from its packaging and hold it firmly with the orange tip pointing downward. Remove the blue safety cap by pulling it straight off. Place the orange tip against the outer thigh and push the device firmly until a click is heard, indicating the injection has started. Hold the Epipen in place for three seconds before removing it. Massage the injection site for 10 seconds to aid absorption.

It is crucial to call emergency services immediately after administering the Epipen, as further medical evaluation and treatment may be necessary. Even if symptoms improve, the effects of epinephrine can wear off, and symptoms can return. Ensuring that individuals with severe allergies always carry an Epipen and are trained in its use can prevent severe complications and save lives.

Using an Epipen

• Remove the Cap: Take off the safety cap.
• Position the Injector: Place the tip against the outer thigh.
• Inject: Push the injector firmly until it clicks, holding it in place for 3 seconds.
• Seek Medical Help: After using the Epipen, call emergency services.

Takeaway to remember

An Epipen is an auto-injector containing epinephrine, used to treat severe allergic reactions (anaphylaxis).
