Swelling of the lips The nurse should reinforce with the client that the epinephrine auto-injector can help treat swelling of the lips. Epinephrine is a medication commonly used to treat severe allergic reactions, also known as anaphylaxis. Swelling of the lips is one of the hallmark manifestations of an allergic reaction. Epinephrine acts quickly to reverse the allergic response by constricting blood vessels, relaxing smooth muscles, and reducing swelling and inflammation.
