Answer

Phototherapy with PUVA, UVA, or UVB is successful in controlling atopic dermatitis but is expensive and may lead to increased risk of melanoma and nonmelanoma skin cancer. Studies evaluating the role of several proposed disease-modifying agents continue to be conducted. Results of studies on IL-4 neutralizing antibody and mast cell depleters are promising, whereas the evidence for probiotics, [16, 17] primrose oil, sodium cromolyn, topical caffeine, and dietary exclusion is inconclusive and requires more research.
