Should I use prednisone or dexamethasone in my patient with newly diagnosed immune thrombocytopenia (ITP)?

By William Aird

In a randomized trial, high-dose dexamethasone (40 mg daily x 4 days) was shown to lead to a faster response compared to prednisone, and without additional toxicity. However there was no difference in platelet count response at 6 months. Consider dexamethasone if quick response is particularly important, for example in a patient who is bleeding or needs to have surgery.
