Photosensitivity induced by fleroxacin

A case of photosensitivity induced by fleroxadn (FLRX) is reported. A 71‐year‐old man had erythema on sun‐exposed areas after 5 months FLRX treatment for prostatitis. The minimal erythema dose to UVA was reduced at the initial examination and became normal 4 weeks after he stopped taking FLRX. Oral photo‐challenge with FLRX 100 mg was positive, but photopatch testing was negative.
