Understanding CSU and SD
CSU patient portrayal.
Chronic spontaneous urticaria (CSU) and symptomatic dermographism (SD) are the 2 most common types of chronic hives.
What is CSU?
CSU can cause hives and itch that may appear and disappear without warning. Unlike hives caused by allergies, CSU doesn’t have any known external triggers. Symptoms come and go for more than 6 weeks and may include raised, itchy hives, swelling, or both.
What is SD?
SD, also called chronic hives from scratching or rubbing on the skin, is the most common form of chronic hives with triggers. Scratching or rubbing on the skin may cause raised, red, itchy hives to appear within minutes.
What happens when treating with antihistamines alone isn't enough?
Antihistamines are the first line of treatment for CSU and SD. But if one doesn’t provide enough relief, you may find yourself trying another. Even with higher doses, hives and itch may come back.
Help break the cycle with RHAPSIDO® (remibrutinib)
If antihistamines alone aren't enough, ask your health care provider about RHAPSIDO.

"I encourage anyone with CSU to talk with their health care provider about their options."
