Latex allergy. Close-up of the lip of a six year old boy showing swelling and blistering caused by an allergy to latex. This condition arose due to latex gloves worn by a dentist examining the boy's mouth. The symptoms of an allergy are caused by the body's immune system mistaking harmless substances for disease-causing organisms. Antibodies in the body detect the allergen to which the patient is sensitized and then trigger the release of a chemical called histamine, which produces an inflammation. The most effective treatment for an allergy is to avoid the cause. Antihistamine drugs and corticosteroid drugs may help to relieve the symptoms.
