Morphine is okay for carcinoid patients but epinephrine is not since it can provoke carcinoid crisis. Epinephrine is sometimes used with local anesthesia to prolong the anesthesia by causing vasoconstriction. Novocain and other local anesthesia do come without epinephrine. Demerol and Fentazine can be used for post operative pain in people who are intolerant of morphine and Percocet.
