Question: is hydrocortisone same as prednisone?
Answer: Prednisone is 4 to 5 times more potent than hydrocortisone and has a longer duration of action, perhaps 12 hours or more. Dexamethasone is 40 to 50 times more potent than hydrocortisone and even longer-acting, 18 to 24 hours. Both of these glucocorticoids are given when a prolonged action is desired.
