Oral psoralen cannot be given to children and pregnant ladies. It also needs to be withdrawn if there are troublesome side effects like nausea and vertigo. If oral psoralen is given, a patient needs sun protection for the eyes for the next 24 hours. Narrowband UVB works well in most patients without psoralen. Therefore the problems linked to psoralen usage are not there with narrow-band UVB. In addition, exposure times are shorter and frequency (number of sessions per week) is also lower with narrow-band UVB. NBUVB is today considered to be more effective in clearing the disease too.
