Hereditary angioedema (HAE) is a rare, autosomal dominant disorder caused by a C1-esterase inhibitor (C1-INH) deficiency (type 1) or qualitative defect (type 2). It is characterized by recurrent subcutaneous or submucosal edema attacks in various organs with a frequency from a few attacks to over one hundred attacks per year. ⋯ In the present case, icatibant proved to be an effective and safe drug for the symptomatic treatment of acute HAE attacks. Its efficacy was not impaired by repeated administrations over a three-year period in this patient.
