I am a hospice nurse and have a patient with Carcinoid cancer and heart disease. He recently fell at home and recieved a humeral Fx. When he went to ER, ER MD said cancer patients should never use Darvocet which patient has been using to control pain even before falling and recieving Fx. Are cancer patients not suppose to take darvocet. We don't use it often but this patient doesn't tolerate stronger opioids. Thanks.
