See Chapter 30 for relative, steroid potencies and doses based on body surface area. Acetate form may also be used for intra-articular and intralesional injection and has longer times to max. effect and duration of action; it should NOT be given IV. Like all steroids, may cause hypertension, pseudotumor cerebri, acne, Cushing syndrome, adrenal axis suppression, GI bleeding, hyperglycemia, and osteoporosis.
Barbiturates, phenytoin, and rifampin may enhance methylprednisolone clearance. Erythromycin, itraconazole, and ketoconazole may increase methylprednisone levels. Methylprednisolone may increase cyclosporine and tacrolimus levels.
