Treatment involves identifying and avoiding the exposure that is causing the disease.
Some people may need to change jobs if they cannot avoid the exposure at work.
Glucocorticoids such as prednisone that have anti-inflammatory effects may be used to treat severe acute or worsening chronic hypersensitivity pneumonitis.
Inhaled steroids such as those used for asthma can sometimes help people with HP.
In some cases, immunosuppressive therapies, which decrease the body's immune response, may stabilize or reverse the lung inflammation of HP.
