What is a typical prednisone dosing for giant cell arteritis?

• A. 5 mg/day for 1 week
• B. 20 mg/day for 6 weeks
• C. 80 mg/day for 2 weeks
• D. 40-60 mg/day for 6 weeks

Answer: (D)

Giant cell arteritis requires rapid, strong suppression of inflammation to prevent vision loss. The standard approach is high-dose prednisone from the start. A typical initial dose is about 40–60 mg per day, used for several weeks before gradually tapering over months as symptoms improve and inflammatory markers normalize. In patients with visual symptoms or high risk of ocular involvement, some clinicians begin with IV methylprednisolone, then switch to oral prednisone. Why this dose fits best: it provides enough glucocorticoid effect to quell the active vasculitis and reduce the risk of permanent vision loss, whereas lower doses listed in the other options would be insufficient to control the disease promptly. The duration of about six weeks aligns with the need for an initial strong response before tapering, whereas a very short course or a much higher dose for only a couple weeks does not sustain suppression of the inflammation.
