Treat HAE at the first sign or symptom of an attack

HAE attacks can occur anywhere on the body, and vary in length and severity. Therefore, it is important to treat HAE at the first sign of an attack.

Learn to recognize the early signs that an attack may be coming. These vary from person to person and may include:



Stomach upset

Muscle and joint pain

Stomach cramps

Numbness or tingling


Many HAE attacks occur without an obvious "trigger." However, you may also come to recognize certain events as triggers. These may include:

  • Anxiety
  • Stress
  • Minor injuries
  • Dental procedures
  • Medications
  • Infections
  • Hormonal changes, such as those occurring during pregnancy or menstruation

Have a plan to treat your HAE attacks

In addition to being aware of the warning signs of an attack, you should have a treatment plan in place to address each HAE attack as soon as it occurs.

Work with your healthcare provider to ensure that you have a treatment plan ready and therapy available so you’ll be prepared to treat your next HAE attack.
