alpha 1-proteinase inhibitor
What is the most important information I should know about alpha 1-proteinase inhibitor?
Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.
What is alpha 1-proteinase inhibitor?
Alpha 1-proteinase inhibitor is a protein (alpha 1-antitrypsin) that occurs naturally in the body and helps prevent breakdown of tissues in the lungs. People who lack this protein because of a genetic deficiency can develop damage to the air sacs in the lungs (emphysema).
Alpha 1-proteinase inhibitor is used to treat alpha 1-antitrypsin deficiency in people with symptoms of emphysema.
Alpha 1-proteinase inhibitor will not cure alpha 1-antitrypsin deficiency, and may not slow the progression of emphysema.
Alpha 1-proteinase inhibitor may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before using alpha 1-proteinase inhibitor?
