A new clinical study suggests that narrow Band Ultraviolet B (NB-UVB) phototherapy is effective, well-tolerated treatment for antihistamine-refractory chronic spontaneous urticaria, offering a viable alternative to oral cyclosporine. CSU, marked by persistent hives and itching lasting more than 6 weeks, often leaves patients and clinicians struggling to find effective treatment beyond antihistamines. The current study highlights NB-UVB phototherapy as a promising contender in this treatment landscape. The participants were divided into 2 groups: one received NB-UVB phototherapy 3-times weekly, while the other was prescribed cyclosporine at 3 mg/kg/day. Overall, the results place NB-UVB phototherapy firmly on the map as a potential alternative to cyclosporine in antihistamine-refractory CSU.
