What is Glassia?
Glassia contains alpha 1-proteinase inhibitor, a protein, also called alpha 1-antitrypsin. This protein occurs naturally in the body and is important for preventing the breakdown of tissues in the lungs.
In people who lack the alpha 1-antitrypsin protein, breakdown of lung tissues can lead to emphysema (damage to the air sacs in the lungs).
Glassia is used to treat alpha 1-antitrypsin deficiency in people who have symptoms of emphysema.
Alpha 1-antitrypsin deficiency is a genetic (inherited) disorder and Glassia will not cure alpha 1-antitrypsin deficiency, and may not slow the progression of emphysema.
You should not use Glassia 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.
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. Glassia 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.
