Zinc pyrithone

Zinc pyrithone (Zinc Omadine, Zincon, Vancide ZP) is fungicidal, bactericidal and used in antidandruff shampoos. In spite of its widespread use only few cases of contact allergy have been reported (Muston et al. 1979). 

Contact allergy to topical corticosteroids appears uncommon their sensitizing potential is probably low. However, allergy should be considered in chronic, therapy-resistant eczema. Tegner (1976) has reviewed the literature.
