Exposure to UV radiation is known to prematurely age the skin over time and increase the risk of skin cancer. These potential effects should be weighed against the potential benefits of the treatment. A history will be taken regarding sun exposure and burning, medications, such as diuretics, that may increase UV sensitivity exposure, and any history of skin cancers. Sometimes, UV light treatments are given in combination with photosensitizing agents, which maximize UV's effects on the skin. Patients who receive these agents, called psoralens, must take care to avoid exposure to sunlight, which also contains UV radiation. Exposure to UV radiation can also cause cataracts and other eye damage, so the patient's eyes must be adequately shielded during the treatments.
