Systematic Review of Phototherapy in Pruritic Disorders

Introduction Pruritus, or the sensation of itch, is the most common symptom among dermatology patients.1 Both cutaneous and systemic conditions may present with pruritus as the primary symptom. Chronic pruritus is a major cause of distress to patients and has a significant impact on quality of life. All ages are affected by pruritus, ranging from children to seniors, and it is the most common dermatologic complaint in the latter group.2,3 For many sufferers of pruritus, topical therapy is not adequate in controlling their symptom. Therefore, providing additional therapeutic options becomes essential for the successful dermatologist. Phototherapy is a safe and efficacious management modality that decreases pruritus and can be used across age groups.4
