About two thirds of patients recover with corticosteroid therapy: the usual corticosteroid administered is prednisolone in Europe and prednisone in the USA; these differ by only one functional group and have the same clinical effect. The corticosteroid is initially administered in high dosage, typically 50 mg per day tapering down to zero over a six-month to one-year period. [ citation needed ] If the corticosteroid treatment is halted too quickly the disease may return. Other medications [ vague ] must be taken to counteract side effects of the steroid.
