The importance of treating your attacks at the start of symptoms

The number of attacks people with hereditary angioedema (HAE) have can vary. Some people might have an attack every 3 days, while others may have only 1 or 2 attacks per year.

When HAE symptoms appear, there is no way to predict how serious an attack will become.

  • HAE attacks usually worsen over 24 hours and gradually get better over the next few days.
  • Sometimes an attack can start in one part of the body and then spread to another before it gets better.

Attacks of the throat are the most dangerous and can be life threatening. If you have an HAE attack involving the throat, inject FIRAZYR as directed and then go to the nearest hospital emergency room right away.

Potential attack triggers

HAE attacks, which include symptoms of swelling and pain, can be triggered by:

  • Stress
  • Medical and dental procedures
  • Hormonal changes
  • Infections, such as a cold or the flu
  • Physical activities, such as gardening, prolonged sitting or prolonged standing

However, many attacks happen without an obvious trigger. That makes it very difficult to predict an HAE attack. Consider keeping a journal to look for trends in activity, stress and acute HAE attacks to help identify your potential triggers.

Some people may also notice certain signs before an HAE attack actually begins, like fatigue, a rash or a tingling sensation on the skin.
