C1 Esterase Inhibitor, Recomb

Uses

This medication is used to treat the swelling problems caused by a certain immune disease passed down through families (hereditary angioedema-HAE). HAE is caused by low levels or improper function of a natural substance produced by the body (C1-esterase inhibitor). Symptoms such as rapid swelling of the hands, feet, limbs, face, tongue, or throat can occur. Swelling of the intestinal tract may cause symptoms such as abdominal cramps, diarrhea, or vomiting. Attacks of swelling may occur without reason. However, anxiety, stress, sickness, and surgery may trigger attacks in some people. This medication works by increasing the level of C1-esterase inhibitor to help treat attacks of sudden swelling due to hereditary angioedema.
