Anaphylaxis is a severe, life-threatening allergic reaction characterized by symptoms of hives and swelling, asthma symptoms, gastrointestinal symptoms, and even low blood pressure. The causes of anaphylaxis are numerous, including foods, medicines, insect stings and bites, latex and other causes. Anaphylaxis can also occur during pregnancy, which can result in a life-threatening situation for the unborn child. The most common causes of anaphylaxis during pregnancy include medications (such as penicillin and related antibiotics) as well as latex exposure. The treatment of anaphylaxis during pregnancy is much the same as for anaphylaxis during non-pregnancy.
