Effect of combining histaglobulin with antihistamines in patients with chronic spontaneous urticaria in a tertiary care hospital setting- a randomized trial.

Chronic Spontaneous Urticaria (CSU) significantly affects quality of life. This study evaluates the efficacy of histaglobulin combined with antihistamine (bilastine) versus antihistamine alone in CSU management. A single-center, open-label, randomized trial was conducted in the dermatology OPD of a tertiary care hospital from September 2023 to August 2024.
