[Photocontact allergy caused by benzydamine (Tantum)].

Three women with a photoallergic dermatitis precipitated by benzydamine are reported. In one patient the cause of the photosensitization was a cream containing benzydamine (Tantum cream), whereas in the other two the reaction occurred after oral administration (Tantum drops). In all three cases the photosensitization was confirmed by a photopatch test that was positive for the active ingredient benzydamine.
