Ranitidine-induced photosensitivity.

We report the case of a 72-year-old male patient who developed a florid photosensitive eruption while on ranitidine therapy. Ultraviolet A sensitivity was detected by irradiation monochromator testing, suggesting drug-induced photosensitivity. Ranitidine was concluded to be the cause of his photosensitivity since the eruption resolved and the phototest abnormalities returned to normal following cessation of therapy. Similar cases have been reported to the Committee on Safety of Medicines but not published.
