Hereditary Angioedema
"I have had a reaction to this medication both times we have tried it with fast heart rate, hypotension, and nausea and vomiting. My symptoms were a little better after starting with Benadryl and Phenergan. I was taking Berinert on  basis of about once a week depending on swelling. I didn&#039;t have a reaction at all with this medicine. My doctor has suggested that we go back to using the Berinert."
