Contact Urticaria Syndrome Treatment & Management

Medical Care
- Patients need to be well versed in the nature of their urticarial reaction (immunologic contact urticaria vs nonimmunologic contact urticaria), in avoidance techniques, and in suitable alternatives.
- Patients with immunologic contact urticaria should purchase medic alert tags delineating their allergens, including potential cross-reacting substances.
- Depending on the degree of reactivity and the ubiquity of the allergen, patients with immunologic contact urticaria may require antihistamines and self-administered epinephrine.
Diet
Affected individuals should avoid foods and food products that trigger their symptoms. One should be aware that food extracts are sometimes used in cosmetics, which may lead to unintended exposure. Additionally, cross-reactivity of latex to foods such as banana, kiwi, and avocado may require additional avoidance.[2] However, advice regarding the avoidance of cross-reactive foods should be given after appropriate skin prick testing or a RAST because not all individuals are affected in this way.
Activity
Affected patients should avoid exposure to trigger substances. A large cohort study following nearly 1000 health care workers found that latex-sensitized health care workers can reduce or eliminate cutaneous symptoms by wearing nonlatex gloves themselves and ensuring their coworkers wear nonpowdered latex gloves (or, ideally, nonlatex gloves). However, patients with respiratory or systemic features may have to work in a completely latex-free environment. A policy of minimizing glove use and using only powder-free gloves prevented any new sensitizations in the 3-year study period.[28]
