What is an EpiPen® and How Does it Work?
An EpiPen® is a life-saving device that contains epinephrine, a medication that can quickly and effectively treat severe allergic reactions. Epinephrine is a hormone produced by the adrenal glands that plays a crucial role in the body’s response to stress, including allergic reactions. When an EpiPen® is injected into a person’s thigh, the epinephrine in the device quickly enters the bloodstream and helps to reverse the symptoms of a severe allergic reaction, also known as anaphylaxis. Epinephrine works by constricting blood vessels and relaxing the airway muscles, which helps to increase blood pressure and open up the airways, allowing the person to breathe more easily. Anaphylaxis is a potentially life-threatening condition that can cause symptoms such as difficulty breathing, swelling of the face and throat, rapid heartbeat, hives or rash, nausea or vomiting, and dizziness or fainting. In severe cases, anaphylaxis can lead to shock, cardiac arrest, or even death if not treated quickly and effectively. The use of an EpiPen® can help to rapidly alleviate the symptoms of anaphylaxis and prevent complications. However, it is important to seek emergency medical attention immediately after using an EpiPen®, as additional treatment may be necessary to fully manage the symptoms of anaphylaxis.When to use an EpiPen®
