Was administered Fluorescein for eye angiogram. Within 2 minutes my face, arms, hands, torso, legs, face, lips went dark red, swelling, intense cramping (diarrhea) and itching all over. HIves came on swiftly with intense shaking of my whole body. Jaw locked up, chest felt terribly heavy, blood pressure dropped to 70/50. Was given intravenous steroid and 50 mg benadryl. Four hours before I was stable. This was antiphylactic shock. I am not allergic to shellfish. This was very scary. Felt I was actually dying and afraid to go to sleep. A horrible experience, one I will never forget. Wish there was a way to know before hand if a person has allergies to this stuff. Wouldn't want to see anyone go thru this. I know I had the concerns of the doctors and staff at the clinic. Brenda 6.26.08
