Why is this medication being recommended?

Prednisone is part of a class of drugs called immunosuppressants. It suppresses the body's immune response and reduces inflammation in your lungs. Because inflammation is the precursor to fibrosis (scarring), we hope prednisone will prevent the formation of lung fibrosis and allow the inflamed lung to return to normal.

What special precautions should I follow?

Before taking prednisone:

• Tell your doctor and pharmacist if you are allergic to prednisone, other medications or any of the inactive ingredients in prednisone tablets or solutions. Ask your doctor or pharmacist for a list of the inactive ingredients.
