Question 9 1. Why is dexamethasone not routinely used instead of prednisolone, which is almost universally used routinely in autoimmune diseases, or other indications for steroids?

Can high doses of dexamethasone be used in acute relapses of multiple sclerosis (MS) in place of pulse methylprednisolone? If so, what is the recommended dosage?
