Background:Many health care workers are sensitized to the proteins in natural rubber latex and get contact dermatitis as a result of wearing latex gloves. Objective:The aim of the study was to evaluate a topical formulation containing a zinc gel (Allergy Guard) as a prophylactic against latex glove-related contact dermatitis. Methods:The study was carried out with volunteers who exhibited mild to moderate contact dermatitis (type IV) after wearing latex gloves as per the protocol. Results:Allergy Guard significantly reduced skin irritation in volunteers who exhibited type IV hypersensitivity when exposed to latex gloves. Allergy Guard also exhibited a barrier effect as shown by the permeation of chlorophyllin dye into the skin of volunteers. Allergy Guard prevented dermal irritation induced by sodium lauryl sulfate. Conclusion:Topical formulations containing a zinc gel may be used to delay or prevent latex sensitivity, especially among health care professionals.
