What is hereditary angioedema (HAE)?
HAE is a rare genetic disorder that can cause sudden episodes of swelling that can be painful and disabling. Learn more about HAE here.
Do I have hereditary angioedema (HAE)?
The only way to find out is to talk with a doctor who knows about HAE. Confirming a diagnosis of HAE usually involves full medical history and a blood test. Learn more about HAE and diagnosis here.
What causes HAE attacks?
Typically, people with HAE are either missing an important protein in their blood called C1-inhibitor, or it doesn’t work the way it should. This can cause another protein, kallikrein, to become overactive. This increase in kallikrein activity results in too much bradykinin, the substance that causes HAE attacks. TAKHZYRO decreases plasma kallikrein activity. See how it works here.
What triggers hereditary angioedema (HAE) attacks?
Some people with HAE have noticed that their attacks can be set off, or triggered, by certain things. Some triggers that have been noted include, repetitive motion like using scissors or physical trauma, like falling off a bicycle or dental surgery. Triggers are different for everyone and some HAE attacks happen without warning. Learn more here.
How is hereditary angioedema (HAE) treated?
There are two main types of HAE treatment: preventive and on-demand. Preventive HAE treatment involves taking medicine routinely to help prevent or reduce the frequency and severity of HAE attacks. On-demand HAE treatment is medicine used to treat the symptoms of an HAE attack. TAKHZYRO is not an on-demand treatment. Talk to your doctor about your options and learn more about treatment types here.
