Chronic inducible urticaria: Clinical presentation, diagnosis, and management

Chronic inducible urticaria (CIndU) is a subtype of chronic urticaria characterized by recurrent itchy wheals and/or angioedema for more than 6 weeks. CIndU has a longer disease duration than chronic spontaneous urticaria (CSU) and wheals are shorter lasting than CSU. CIndU incudes physical and non-physical urticaria. Triggers and diagnosis of subtypes of CIndU differ from each other. Patient education for avoiding triggers is an important aspect of the treatment of CIndU. There is no significant difference in the treatment approach for CIndU and CSU. In this article, we have discussed different types of CIndU, their clinical features, diagnosis, and management.
