What Is Depo-Medrol Used For?
Depo-Medrol is a corticosteroid injection used to treat inflammatory conditions affecting multiple body systems when other treatments may not be suitable.
Primary Uses
Depo-Medrol treats disorders of many organ systems including skin conditions, lung problems, eye inflammation, gastrointestinal tract issues, nervous system disorders, joint inflammation, and blood disorders. It’s also used when the adrenal gland doesn’t function correctly.
How It Works
Depo-Medrol works by reducing inflammation and changing the body’s natural immune response when it’s not working properly. This helps control symptoms and reduce tissue damage caused by inflammation.
Medical supervision: This medication is only available with a doctor’s prescription and will be administered under medical supervision for your safety.

Administration Methods
The injection may be given into a muscle (intramuscularly), into a joint (intra-articularly), or into a lesion (intralesional). The dose and injection site will depend on your condition and how you respond to treatment. Due to serious safety risks, it must never be injected into the spinal cord or into a vein.
