What is methylprednisolone, and how does it work (mechanism of action)?
Methylprednisolone family of products include methylprednisolone, methylprednisolone acetate (Medrol, Depo-medrol), and methylprednisolone sodium acetate (Solu-medrol).

What are the side effects of methylprednisolone?
Adverse effects of methylprednisolone depend on dose, duration and frequency of administration. Short courses of methylprednisolone are usually well-tolerated with few, mild side effects. Long term, high doses of methylprednisolone may produce predictable and potentially serious side effects. Whenever possible, the lowest effective doses of methylprednisolone should be used for the shortest length of time to minimize side effects. Alternate day dosing also can help reduce side effects.

What is the dosage for methylprednisolone?
Dosage requirements of corticosteroids vary among individuals and the diseases being treated. In general, the lowest effective dose is used. The oral dose range is 2-60 mg daily depending on the disease. Depo-medrol doses are 10-80 mg injected into muscle every 1-2 weeks, and Solu-medrol doses are 10-250 mg intravenous or intramuscular injections up to 6 times daily. The initial dose should be adjusted based on response. Corticosteroids given in multiple doses throughout the day are more effective but also more toxic than the same total daily dose given once daily, or every other day.
Oral methylprednisolone should be taken with food.
