Abstract:
Hereditary angioedema (HAE) is an autosomal dominant disorder. Considerable rate of mortality determines the importance
of disease. In this paper, a patient with HAE who developed severe facial angioedema after the first dose of an antidepressant
(Escitalopram) prescribed by a psychiatrist because of diagnosis of depression, was presented and discussed. In the presented
case, severe facial angioedema was not found to be clearly associated with a particular cause. There were possibilities such as
sporadic/idiopathic attack or depression related attack. However, occurrence of an acute attack soon after a newly started drug had
to draw attention to Escitalopram. So, in patients with HAE under an antidepressant treatment, antidepressant related angioedema
must be kept in mind when the HAE control deteriorated.
