Answer

Narrowband UV-B (NB-UVB) is widely used and has become the first choice of phototherapy for adults and children with generalized vitiligo. Wavelengths of 311-312 nm typically are used. Treatment frequency is 2-3 times weekly. This treatment can be safely used in children, pregnant women, and lactating women. However, phototherapy may be difficult in pediatric patients who may be unable to cooperate. Short-term adverse effects of NB-UVB include burning, pruritus, and xerosis.
