What should you do for a person who has been stung by yellow jackets and shows severe allergic reaction symptoms?

Administering an injection of epinephrine using an autoinjector is the appropriate response for someone experiencing severe allergic reactions, such as anaphylaxis, to yellow jacket stings. Epinephrine works quickly to counteract the life-threatening effects of an allergic reaction, including difficulty breathing, swelling, and a rapid drop in blood pressure. By stimulating the heart, relaxing the muscles around the airways, and reducing swelling, epinephrine can stabilize the individual until further medical help arrives.

In a severe allergic reaction, the immediate use of epinephrine can be life-saving. It is crucial for individuals who know they have severe allergies to carry an autoinjector and to use it without delay when symptoms arise. Given that this is an emergency situation, rapid action is essential to prevent potentially fatal complications.
