adrenalínpenna

An adrenalínpenna, also 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 food, insect stings, or medications. The adrenalínpenna contains a pre-measured dose of epinephrine, a hormone that counteracts the symptoms of anaphylaxis.

When a person experiences an anaphylactic reaction, their body releases histamine and other chemicals that can cause symptoms like difficulty breathing, swelling of the throat and tongue, hives, a drop in blood pressure, and loss of consciousness. Epinephrine works by constricting blood vessels, which increases blood pressure, and by relaxing the muscles in the airways, which helps to open them up and ease breathing. It also reduces swelling and can help to prevent further allergic reactions.

The adrenalínpenna is designed for easy self-administration or administration by a caregiver. It typically consists of a spring-loaded needle that is activated by pressing the device firmly against the outer thigh. The needle is automatically retracted after the epinephrine is injected. It is crucial for individuals with a history of severe allergic reactions to carry at least two adrenalínpennas with them at all times and to know how to use them. After using an adrenalínpenna, immediate medical attention from emergency services is always necessary, as the effects of epinephrine can be temporary and a second phase of the allergic reaction may occur. Training and regular review of its use are highly recommended for both patients and their caregivers.
