Epipen is an injection that has epinephrine basically it’s a chemical that narrows blood vessels and gives you more air ways to the lungs that reveals the effects of allergy

Ooh can I get brainliest?

EpiPen is just one of the brand names of devices known generically as Epinephrine Auto-Injectors. This medication acts on the whole body to block the progression of the allergic response. It constricts the blood vessels, leading to increased blood pressure, and decreased swelling.

How to inject:

should only be injected into the middle of your outer thigh (upper leg), through clothing if necessary. Do not inject into your veins, buttocks, fingers, toes, hands or feet. Hold the leg of young children firmly in place before and during injection to prevent injuries.
