Mordercai: And so these patients will also present with lip, tongue and facial swelling, but they do not have any rash. They don’t have itching or IgE to carry out all that stuff is absent. This is not a histamine reaction. And so it’s not like with a Type I response where you’re going to give antihistamines right away. This is more supportive care and get their airway control.
