About HAE

What is hereditary angioedema (HAE) and how is it treated?

HAE is a rare genetic condition that causes repeat episodes of severe swelling in the body, especially the face, arms, legs, airway, and intestinal tract.

Everyone living with HAE experiences their disease differently, but regardless of where you are in your journey, HAE likely affects—or has affected—your life in a number of ways.

Treating your HAE

There are 2 types of therapies used to treat HAE.

Rescue therapy

Rescue therapy, or acute therapy, is used to help manage or lessen symptoms when an attack is coming on or has already started.

Preventative therapy

Preventative therapy, or prophylactic therapy, is taken regularly as a way to help stop HAE attacks from happening.

Because treatment with rescue therapy alone is not always enough, people living with HAE often use both types of therapy to manage their disease. Long-term treatment with preventative therapy is the best way to prevent future HAE attacks.

As your life changes, your treatment plan might need to change, too

Making decisions with your healthcare team can lead to better results. As you and your healthcare provider discuss the preventative therapy that‘s right for you, here are some factors to consider:

Injection needle

How it‘s given (injection, infusion, orally)


How it fits into your lifestyle


How safe it is

Attack prevention

How well it prevents attacks

Rescue therapy

How it may help reduce the use of rescue therapy

Don‘t be afraid to advocate for yourself to get what you want out of HAE management

Every person‘s experience with HAE is unique. But there‘s no one who understands your experience and what you want better than you.

It‘s important to discuss your unique needs and goals with your healthcare provider, because they‘re what make you, you:
