Psoralen and UVA Light Therapy (PUVA) for Psoriasis
What To Think About
Psoralens applied to the skin (topical) may help to avoid some side effects of oral medicines used for PUVA. They may be especially helpful when psoralens taken by mouth (oral) cause severe nausea. Topical psoralens may be used for psoriasis that affects only a small part of the skin.
Topical psoralens, such as those given in bath water, are as effective as oral psoralens. But if the light treatments are given in a doctor's office, a topical psoralen may be less convenient.
