HAE symptoms

FIRAZYR is a medicine used to treat acute attacks of hereditary angioedema (HAE) in adults 18 years of age and older.

Symptoms can vary from person to person and attack to attack

Hereditary angioedema (HAE) can cause attacks of swelling in any part of the body, but characteristic locations include the skin (eg, face, hands, feet, genitals), stomach (abdomen), and throat. Before an attack, some patients experience early warning signs, also called prodromes, such as tingling, rash, fatigue, or nausea.
