How Does Medrol Work?

Methylprednisolone binds to glucocorticoid receptors and changes gene expression involved in inflammation and immune responses. It reduces inflammatory cell activity and the production of inflammatory mediators. It also has systemic effects on glucose metabolism, protein breakdown, and adrenal hormone regulation.

Who Is Treated With Medrol?

Medrol is used for selected rheumatoid and autoimmune disorders, serious allergic conditions, inflammatory skin and respiratory diseases, certain blood disorders, and endocrine conditions including adrenocortical insufficiency when clinically indicated. Systemic fungal infections and known hypersensitivity to its ingredients are contraindications.

How Is Medrol Dosed?

The initial oral dose commonly ranges from 4 mg to 48 mg daily, depending on the condition and severity. Higher doses are used in selected clinical situations. Doses are adjusted to response and gradually reduced to the lowest dose that controls the condition. Short tapering dose packs have separate instructions. Prolonged treatment is withdrawn gradually rather than stopped abruptly.

What Serious Risks Are Linked to Medrol?

Medrol suppresses immune function and can increase the risk of serious infections or reactivate latent infections. Other serious concerns include adrenal suppression, high blood glucose, elevated blood pressure, fluid retention, osteoporosis, gastrointestinal ulceration, psychiatric reactions, cataracts, and glaucoma. Abrupt withdrawal after prolonged treatment can cause adrenal insufficiency.
