[Consensus document on phototherapy: PUVA therapy and narrow-band UVB therapy]

It is essential to develop a consensus document on phototherapy in order to adapt this procedure to the specific characteristics, needs and reality of our milieu. Using a review of existing literature on the subject and the experience of its own members as a reference, the Spanish Photobiology Group (GEF) of the Spanish Academy of Dermatology and Venereology (AEDV) has developed some therapeutic guidelines for the most widely used modes of phototherapy: PUVA therapy and narrow-band UVB (NBUVB) therapy. These guidelines deal with generalities about the equipment, calibration and regulation in phototherapy booths, and the concept and indications for these forms of treatment are reviewed. Recommendations are also proposed regarding patient selection, therapeutic procedures, associated pharmacological agents of interest and the prevention and management of adverse effects. The consensus document is designed as a flexible and practical instrument intended for use in daily clinical practice, aimed at optimizing the possibilities of phototherapy while reducing risks for patients and therapists.
