What should a person with serious allergies always carry?

A person with serious allergies should always carry medication or an epinephrine auto-injector because it is essential for managing severe allergic reactions, commonly known as anaphylaxis. An epinephrine auto-injector delivers a life-saving dose of epinephrine, which can quickly reverse the symptoms of a severe allergic reaction, such as difficulty breathing, swelling of the throat, and a drastic drop in blood pressure. This prompt treatment is crucial as anaphylaxis can progress rapidly and become life-threatening.

While antihistamines can help alleviate mild allergy symptoms, they are not effective for severe reactions and should not be relied upon solely in such situations. Carrying contact information might be helpful in emergencies, but it does not provide any immediate treatment for an allergic reaction. Sunscreen, while important for preventing sun-related skin damage, does not address allergy management at all. Therefore, ensuring access to an epinephrine auto-injector is the most critical action for someone with serious allergies.
