Prednisolone belongs to a group of medicines called corticosteroids. It is sometimes referred to as an oral steroid, or simply, a steroid. Oral steroids are used to treat a large number of conditions. Some examples include: asthma, inflammatory bowel diseases (for example, Crohn's disease, ulcerative colitis), autoimmune diseases (for example, systemic lupus erythematosus (SLE), sarcoidosis), joint and muscle diseases (for example, rheumatoid arthritis), and allergies. They are also used in the treatment of some cancers. Steroids work in part by suppressing your body's immune system, and this reduces swelling and inflammation.
