This medication is used to treat conditions such as arthritis, blood disorders, severe allergic reactions, certain cancers, eye conditions, skin/kidney/intestinal/lung diseases, and immune system disorders. It decreases your immune system's response to various diseases to reduce symptoms such as swelling, pain, and allergic-type reactions. Methylprednisolone is a corticosteroid hormone. This injectable form of methylprednisolone is used when a similar drug cannot be taken by mouth or when a very fast response is needed, especially in patients with severe medical conditions. Talk to your doctor about the risks and benefits of methylprednisolone, especially if it is to be injected near your spine (epidural). Rare but serious side effects may occur with epidural use.

Methylprednisolone may also be used with other medications in hormone disorders.
