What should be done for a patient with severe allergic reactions who is conscious?

For a patient experiencing a severe allergic reaction, also known as anaphylaxis, the priority intervention is to administer an epinephrine auto-injector if one is available. Epinephrine is a critical medication that counteracts the life-threatening symptoms of anaphylaxis. It works by constricting blood vessels, which increases blood pressure, and by opening the airways, allowing the patient to breathe more easily. This rapid response is essential, as anaphylaxis can escalate quickly and become fatal if not addressed promptly.

While waiting for emergency services is important, calling for help without taking action does not provide the immediate care that is needed in this situation. Providing water or food can pose a risk and is inappropriate; water may exacerbate swallowing difficulties if the patient is experiencing throat swelling, and giving food can lead to choking or further complications. Thus, administering an epinephrine auto-injector is the most effective and life-saving intervention in the case of a conscious patient suffering from a severe allergic reaction.
