The best treatment is to avoid the provoking allergen, as chronic exposure can cause permanent damage and acute disease is often self-limiting. The identification of the provoking antigen and its location must be ascertained by conducting an exposure assessment. Home cleaning is one method of antigen avoidance. 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
