epinefriinikynää

Epinefriinikynä, commonly known as an epinephrine auto-injector, is a medical device used for the emergency treatment of anaphylaxis. Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen such as certain foods, insect stings, or medications. The device contains a pre-measured dose of epinephrine, also known as adrenaline, a hormone that helps to reverse the symptoms of anaphylaxis.

The epinephrine auto-injector is designed for easy self-administration or administration by another person. It typically consists of a spring-loaded needle that is automatically introduced into the outer thigh muscle when the device is pressed against the skin. The epinephrine is then injected into the muscle, where it is quickly absorbed into the bloodstream. Epinephrine works by constricting blood vessels, which helps to raise blood pressure, and by relaxing the muscles of the airways, which can open them up and ease breathing difficulties. It also reduces swelling and hives.

Individuals diagnosed with a risk of anaphylaxis, such as those with severe allergies, are often prescribed an epinephrine auto-injector. It is crucial for these individuals and their caregivers to be trained in its proper use and to carry the device with them at all times. Symptoms of anaphylaxis can include difficulty breathing, wheezing, hives, swelling of the lips or tongue, dizziness, and a sudden drop in blood pressure. Prompt administration of epinephrine can be life-saving. After using an epinephrine auto-injector, immediate medical attention is still necessary, as symptoms can recur or other complications may arise.
