Dexamethasone treatment for congenital adrenal hyperplasia.

Ten patients with congenital adrenal hyperplasia (three males, seven females; aged 12-29 years) had their usual glucocorticoid treatment changed to dexamethasone in three crossover dosage regimens. A starting dose of 5 micrograms/kg/day is suggested but as no one dose regimen resulted in adequate control the timing of the dose must be decided for each patient.
