Treatment

If you have hypersensitivity or chemical pneumonitis, your doctor will recommend eliminating exposure to the allergen or chemical irritating your lungs. This step should help lessen your symptoms.

In severe cases of pneumonitis, treatment may also include:

  • Corticosteroids. These drugs work by suppressing your immune system, reducing inflammation in your lungs. Corticosteroids are usually taken as a pill. However, long-term corticosteroid use also increases your risk of developing infections and is associated with the thinning of bones (osteoporosis).
  • Oxygen therapy. If you're having a lot of trouble breathing, you may need oxygen therapy through a mask or plastic tubing with prongs that fit into your nostrils. Some people need oxygen therapy constantly, while others might need it only during exercise or sleep.
