What Is Prednisone?

Prednisone belongs to a class of medicines known as corticosteroids. These medications suppress the immune system and prevent the body from releasing substances that trigger inflammation. Prednisone is used in the treatment of conditions such as cancer, autoimmune diseases, severe allergies, arthritis, and breathing difficulties. Most patients take this medication by mouth, and it can be used for short and long-term therapy. Side effects are more likely to occur when prednisone is used for a long time, and taking doses higher than 7.5 milligrams per day could further increase a patient's chances of developing side effects.
