Medically reviewed by Last updated on May 7, 2020.

Applies to the following strengths: 1 mg; 5 mg; 10 mg

Usual Adult Dose for Cushing's Syndrome

INITIAL DOSE: 2 mg orally 2 times a day

TITRATION: Initially, titrate the dose by 1 to 2 mg 2 times a day, no more frequently than every 2 weeks based on the rate of cortisol changes, individual tolerability and patient improvement. If a patient tolerates 10 mg 2 times a day and continues to have elevated 24-hour urine free cortisol (UFC) levels above upper normal limit, the dose can be titrated further by 5 mg 2 times a day every 2 weeks. Monitor cortisol levels from at least two 24-hour urine free cortisol collections every 1 to 2 weeks until adequate response is maintained.

MAINTENANCE DOSE: Should be individualized and determined by titration based on cortisol levels and patient's symptoms. Maintenance dose varies between 2 and 7 mg 2 times a day.
Maximum maintenance dose: 30 mg orally 2 times a day; when maintenance dose is achieved, monitor cortisol levels at least every 1 to 2 months or as indicated.

Use: For the treatment of adult patients with Cushing's disease for whom pituitary surgery is not an option or has not been curative

Renal Dose Adjustments

No adjustment recommended. In patients with moderate to severe renal impairment urine free cortisol (UFC) levels should be interpreted with caution due to reduced UFC excretion.

Liver Dose Adjustments

More frequent monitoring of adrenal function may be required during dose titration in all patients with hepatic impairment:
-Mild (Child-Pugh A) hepatic impairment: No adjustment recommended.
-Moderate (Child-Pugh B) hepatic impairment: Starting dose is 1 mg orally 2 times a day
-Severe (Child-Pugh C) hepatic impairment: Starting dose is 1 mg orally once a day in the evening.



Safety and efficacy have not been established in patients younger than 18 years.
