Photosensitivity from pyridoxine hydrochloride (vitamin B6)

Journal of the American Academy of Dermatology, 1996
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.

Photoallergic Drug Eruption Due to Pyridoxine Hydrochloride

The Journal of Dermatology, 1996
AbstractPhotoallergy to vitamin B6 is very rare; only a few cases of contact dermatitis and one case of photosensitive dermatitis due to pyritinol have been reported. We report here the first case of photoallergy drug eruption due to pyridoxine hydrochloride.A 71‐year‐old man developed papulo‐squamous erythemata which were confined to sun‐exposed sites.
