When you are having an allergic reaction or extreme itching after a sunburn or rash, how does epinephrine work to stop it?

I've never given epinephrine for extreme itchiing or sunburn, or even a rash. I've only ever given it for a life threatening allergic reaction, which we call anaphyllaxis. Besides giving the epinephrine, I also gave them injectable diphenhydramine and a steroid. I would imagine it help blocks the histamine receptors, and helps open the lungs up for better respirations. It's been too long since I've went to school to tell you exactly what goes on.

Epinephrine increases the speed and force of heart beats and, therefore the work that can be done by the heart. It dilates the airways to improve breathing and narrows blood vessels in the skin and intestine so that an increased flow of blood reaches the muscles and allows them to cope with the demands of exercise or stress. Basically,it gets blood an oxygen to parts of your body that need it in response to you reaction.
