When antihistamines alone aren't enough1
 

 

Patient portrayal.

Many patients take antihistamines but still struggle with chronic spontaneous urticaria (CSU)2,3

CSU symptoms can last months, years, or sometimes longer. It’s a long-term condition that requires continued management. When patients are unable to manage their symptoms, having CSU can feel frustrating.2,4-6

*Based on the Urticaria Voices study, a multinational, noninterventional, cross-sectional, online survey conducted from February 2022 to September 2022 in 582 patients with CSU. Overall, 33% of patients reported using biologics in combination with, or as an add-on to, other therapies.7

Rapid Recaps: CSU burden and treatment gaps

Hear from lead experts, Dr Michael Blaiss, Dr Adam Friedman, and Dr Priya Bansal, on the challenges and treatment gaps that patients with CSU face, including the impact of symptoms such as hives, itch, and/or angioedema.

Angioedema associated with CSU is typically non life–threatening12

  • Typically, no risk of anaphylaxis. Angioedema in CSU does not usually involve airway compromise12

  • Angioedema involves sudden tissue swelling. Swelling commonly involves lower dermis and subcutaneous tissue or mucous membranes (eg, lips, eyelids)8,13

Patients with CSU experience a spontaneous occurrence of wheals, angioedema, or both due to no known external triggers.2,4,8,9,11 You play a crucial role in helping them understand the facts.

BTK plays a key role in CSU14
