In the current treatment of mold allergy, there are two modalities: Preventive and therapeutic approaches. Preventive approaches include measurements against indoor as well as outdoor molds. Relative humidity is suggested to maintain at <50% indoor environments. Windows are kept closed in warm months and air-conditioning ought to be used. Indoor plants, as a possible cause of allergen, should be exposed to direct sunlight from time to time.Visible molds are cleaned and mold-infested resources are should be discarded from houses. Washable surfaces must be cleaned with 5% bleach and detergent solution. Damp carpets are ought to dried out quickly and to think taking them away if humidity is not immediately goes away. In bathrooms, curtains and tile should be regularly checked and mended to keep waterproof. Firewood or newspaper piles or old books are regularly scrutinized and thrown away as necessary. Drip pans for fridges, garages and basements at homes should be regularly checked and cleaned. Water leaks in dwellings should be fixed swiftly.In outdoor environment, intense exposure to moldy plants must be avoided. A well-fitted particulate mask when functioning with moldy objects ought to be used. Air-conditioned vehicles should be utilized. Therapeutic approaches mentioned here for fungal allergy is specifically mold allergen immunotherapy in addition to pharmacotherapy against the effects of mold allergy. Mold allergen immunotherapy, as a specific therapy of fungal allergy, is previously hindered by the poor quality of most of the commercial extracts. There have been only several studies evaluating the efficacy of allergen immunotherapy with Alternaria extracts in patients with respiratory mold allergy.A meta-analysis demonstrated that clinical efficacy of allergen immunotherapy with mold extracts was revealed in 79 actively treated cases in 4 controlled trials, with only 2 mold species, namely Alternaria alternate and Cladosporium herbarium. Recently the American Academy of Allergy, Asthma & Immunology concluded that immunotherapy might be effective for mold allergy. In near future, diagnosis and therapy for mold allergy will be more decisive and effective with newly developed production techniques and methods.
