Prednisolone is a corticosteroid medicine widely used to reduce inflammation and suppress the immune system in a variety of conditions. Doctors prescribe it for allergic reactions, asthma, rheumatoid arthritis, lupus, and inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease. It is also used in certain skin disorders, eye inflammations, and respiratory problems, where it helps relieve swelling, redness, and irritation. In more serious cases, prednisolone is given to manage autoimmune diseases, blood disorders, and some cancers, as it can control abnormal immune activity and improve patient comfort.
