Quick Answer: Congenital adrenal hyperplasia (CAH) treatment centers on glucocorticoid replacement to suppress ACTH and the androgen excess, along with mineralocorticoid replacement (fludrocortisone) in salt-wasting forms. Hydrocortisone is preferred in children; adults may use prednisolone or dexamethasone. Salt supplementation is added in infants. Stress dosing during illness is essential to prevent adrenal crisis.
