Recommended treatments for pneumonitis, particularly hypersensitivity pneumonitis, include eliminating exposure to antigens and taking pain medications, suggests the United States National Heart, Lung and Blood Institute. As of 2015, there is no known cure for this disease.
Exposure to antigens, such as chemicals, dust particles and molds, may cause adverse reactions in the body that can result in hypersensitivity pneumonitis. Early detection of this disease may lead to a reversal if patients completely avoid the substances that trigger their condition.
For persistent hypersensitivity pneumonitis, a physician may recommend the use of corticosteroids, such as prednisone, to minimize swelling in the lungs. Antihistamines and bronchodilators are generally ineffective for hypersensitivity pneumonitis, according to the American Lung Association.
