Phototherapy is a safe and effective treatment for many dermatologic conditions. With the advent of novel biologics and small molecule inhibitors, it is important to critically evaluate the role of phototherapy in dermatology. Surveys have shown that many dermatology residency programs do not dedicate time to teach residents how to prescribe or administer phototherapy. Limitations of phototherapy include access to a center, time required for treatments, and insurance approval. Home phototherapy, a viable option, is also underutilized. However, it should be emphasized that modern phototherapy has been in use for over 40 years, has an excellent safety profile, and does not require laboratory monitoring. It can be safely combined with many other treatment modalities including biologics and small molecule inhibitors. In addition, phototherapy costs significantly less than these novel agents. Dermatologists are the only group of physicians who have the expertise and proper training to deliver this treatment modality to our patients. Therefore, in order to continue to deliver high quality, cost-effective care, it is imperative that phototherapy be maintained as an integral part of the dermatology treatment armamentarium.Copyright © 2020 American Academy of Dermatology, Inc.
