Alpha 1-proteinase inhibitor

You should not use this medication if you have ever had an allergic reaction to alpha 1-proteinase inhibitor, or if you have an IgA (immunoglobulin A) deficiency or antibody against IgA.

Some brands of alpha 1-proteinase inhibitor must be mixed with a liquid (diluent) before given as an injection. If you are using the injections at home, be sure you understand how to properly prepare and store your medicine.

Call your doctor at once if you have a serious side effect such as fever, chills, body aches, flu symptoms, mouth sores, pain or burning when you urinate, wheezing, chest pain or tightness, trouble breathing, or vision changes.

Alpha 1-proteinase inhibitor is made from human plasma (part of the blood) which may contain viruses and other infectious agents. Donated plasma is tested and treated to reduce the risk of it containing infectious agents, but there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.
