Can a person be allergic to epinephrine?
In most cases, a true allergy to epinephrine doesn’t exist. The component of our immune system that causes respiratory-system swelling is tuned to react to foreign allergens. Because epinephrine is naturally present in your body, a minor, additional injected amount of epinephrine is unlikely to cause allergic reaction.
Does epinephrine neutralize the allergen?
For severe allergic reactions which lead to hypotension, epinephrine helps to increase blood flow through veins by constricting blood vessels. By binding to receptors on smooth muscles of the lungs, epinephrine helps to relax the muscles blocking the airways and allows breathing to return to normal.
