Treatment seeks to identify the offending allergen and avoid further exposure to it. A change of occupations may be necessary if future worksite exposure is unavoidable. In chronic forms of the disease, treatment with glucocorticoids (a type of steroid drugs) can be tried because this may decrease inflammation.

Most symptoms resolve after exposure to the allergen is limited.

Pulmonary fibrosis is a possible complication of hypersensitivity pneumonitis.

Call your health care provider if symptoms of hypersensitivity pneumonitis develop.
