“…20 Treatment is most effective when given early in the course of active disease, with the literature now favouring high-dose intravenous glucocorticoid pulses for moderate to severe TED, with response rates of about 80% for parenteral treatment, as compared with about 60% for the oral route. 21 Although the parenteral route has fewer side effects than oral administration (56% and 85%, respectively), 22,23 it is nevertheless associated with significant morbidity in up to 6% of cases, and should be avoided in patients with a history of hepatic, cardiovascular or renal morbidity, uncontrolled hypertension, and diabetes. [24][25][26][27][28] The risk of serious systemic side effects appears to be dose related, being reported mainly when consecutive or alternating doses greater than 500mg have been given.…”
