HAE Diagnosis and Treatment
Receiving a hereditary angioedema (HAE) diagnosis
Since HAE is rare, many doctors will never see a patient with HAE, which can lead to delayed diagnosis or misdiagnosis for some patients. Also, HAE symptoms are often mistaken for other things, like allergies, appendicitis or gastrointestinal problems.
HAE is usually passed down through families, so your doctor will likely ask if anyone else in your family has been diagnosed.
To know for certain if you have HAE, your doctor may also perform a blood test to measure protein levels. Measuring levels of the proteins C4 and C1-INH will not only help determine if you have HAE, but will also help identify the type.
HAE treatment options
There is currently no cure for HAE, but there are medicines available to help prevent and treat acute attacks.
FIRAZYR is a medicine used to treat acute attacks of HAE in adults 18 years of age and older. You can carry FIRAZYR with you and administer yourself as soon as you recognize the symptoms of an acute HAE attack. A healthcare provider will teach you or your caregiver how to inject FIRAZYR.
FIRAZYR is the only HAE medicine that directly blocks bradykinin from binding the B2 receptor. Bradykinin is a protein thought to be responsible for characteristic HAE attack symptoms of swelling, inflammation and pain.
- Comes in a prefilled, single-use, self-injectable syringe
- Needs no refrigeration, mixing or special handling (store between 2 - 25° C (36 - 77° F))
- Has been proven effective in the treatment of acute HAE attacks that occur in the abdomen, skin, throat and other parts of the body
Note: It is important to know that laryngeal (throat) attacks can become 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.
