title: Photosensitivity due to alprazolam with positive oral photochallenge test after 17 days administration.
abstract: We describe a 65-year-old male patient with photosensitivity due to alprazolam. A photopatch test was negative. An oral photochallenge test after taking alprazolam for 17 days with UVA irradiation was positive. Alprazolam, a lipid-soluble drug, may require long duration of administration to cause photosensitivity.
