Methylprednisolone is a synthetic corticosteroid medication used to reduce inflammation and suppress the immune response. It is commonly prescribed for conditions such as Allergies, Asthma, autoimmune disorders, and certain types of cancer. Methylprednisolone can be administered orally, intravenously, or as an injection, and it works by mimicking the effects of hormones produced by the adrenal glands. Like all corticosteroids, it may have side effects and should be used under medical supervision.
