title: Photosensitivity from pyridoxine hydrochloride (vitamin B6).
abstract: We describe a 35-year-old female patient with photosensitivity due to pyridoxine hydrochloride (vitamin B6) in a multivitamin over-the-counter preparation. Photopatch and oral photochallenge tests using pyridoxine hydrochloride and UVA irradiation were positive. Larger doses for therapeutic use could cause photosensitivity.
