If avoidance is not possible, such as in the case of some workplace exposures, minimizing exposure can be accomplished through various means including the implementation of PPE or proper ventilation of a workplace. Corticosteroids such as prednisolone may help to control symptoms but may produce side-effects. In the case of severe, end-stage pulmonary fibrosis arising from chronic exposure, lung transplant may be the only viable option. In addition to steroids for fibrotic disease, other immunosuppressants (Azathioprine, Mycophenolic acid) and anti-fibrotic agents (Nintedanib) may be used although their effectiveness is unclear

Prognosis
There are few studies examining longitudinal outcomes in patients diagnosed with hypersensitivity pneumonitis. One study in the US showed about a 0.09 to 0.29 per million increase in mortality rates although the cause specific cause was unclear. Most of the outcomes collected are from patients diagnosed with farmers or bird breeders lung and thus the degree to which this data can be extrapolated to other types of HP is uncertain. Generally outcomes for HP in those with acute disease are very good if exposure is avoided. However, those with subacute or chronic type, especially with biopsy proven fibrosis fair much poorer death rates comparable to people diagnosed with Interstitial pulmonary fibrosis.
