This medicine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention.

Alpha 1-PI is made from donated human blood. Some human blood products have transmitted certain viruses to people who have received them. The risk of getting a virus from alpha 1-PI is very low and has been greatly reduced in recent years. This is the result of required testing of human donors for certain viruses, and testing during the manufacture of these medicines. Although the risk is low, talk with your doctor if you have concerns. Your doctor may give you a hepatitis B vaccine before receiving this medicine.
