title: Drug-induced photosensitivity.
abstract: (1) Photosensitivity reactions are cutaneous disorders due to exposure to ultraviolet (UV) radiation of natural or artificial origin. They occur or are more prevalent on unprotected skin. The main clinical manifestations are burns, eczema-like rash, urticaria, pigmentation, or onycholysis; (2) Many drugs increase cutaneous sensitivity to UV, sometimes for therapeutic purposes, but it is generally an unwanted effect.
