What if the allergen can be eliminated?
In the case of an allergen in the environment, such as dust, pollen, and mold, a thorough house cleaning, along with other careful preventive measures, will cut down on the exposure. However, if the allergen is seasonal pollen, moving may not be the solution since there might be tree or weed pollens in the new location which could bring about the development of another, equally distressful allergic reaction.
