Acute attacks of HAE are unpredictable, disabling and can be life-threatening if the airway is affected.

Quickly and effectively treating these attacks with acute treatments (also known as on-demand treatments) prevents complications and minimizes interference with everyday activities.

Prophylactic treatment is medication taken on a regular schedule to reduce the frequency and/or severity of HAE attacks.

This can be done on a long-term or short-term basis. Long-term prophylaxis is typically given regularly for weeks, months, or years in an effort to minimize the overall attack burden. Short-term prophylaxis is typically given just prior to a surgical or dental procedure to prevent an HAE attack during or following the procedure.

People with HAE receiving prophylactic treatment still need an effective on-demand treatment plan in the event the prophylactic treatment is not 100% effective.

CINRYZE® (C1 inhibitor) is indicated for routine prevention against HAE attacks in adults, adolescents and pediatric patients (6 years of age and older). Cinryze is delivered intravenously and is approved for self-administration. The manufacturer, Takeda, provides further details on their product page.

Please make an appointment with your HAE specialist if you need a prescription for an HAE treatment. Family physicians cannot prescribe HAE treatments.

If you think you may have HAE and do not yet have a specialist, the first step is to visit your family physician. They can refer you to an HAE specialist. If you and/or your family physician need help finding an HAE specialist in your area, please refer to the Canadian HAE Network (CHAEN)‘s website where you will find a list of HAE treating physicians who are members of CHAEN.

IMPORTANT: Patients with the slightest hint of throat swelling should seek immediate treatment to ensure that their airway is not compromised. Medicines used to treat swelling from allergies, such as corticosteroids (prednisone), antihistamines, and epinephrine are not effective treatments for HAE.
