Dosing Adult

Diagnostic use: Screening of adrenocortical insufficiency:

Cosyntropin powder for injection (IM, IV) or cosyntropin solution for injection (IV only [manufacturer labeling does not recommend IM administration of solution for injection]):

Conventional dose: 0.25 mg; Note: Doses in the range of 0.25 to 0.75 mg have been used in clinical studies; however, maximal response is seen with 0.25 mg dose. When greater cortisol stimulation is needed, an IV infusion may be used: 0.25 mg administered at 0.04 mg/hour over 6 hours

Low-dose protocol (off-label dose): 1 mcg (Abdu 1999); Note: The use of the low-dose protocol has been advocated by some clinicians, particularly in mild or secondary adrenal insufficiency. The low-dose protocol is not recommended in critically-ill patients (Marik 2008). The Endocrine Society practice guideline recommends the conventional dose (ie, 0.25 mg) for diagnosing primary adrenal insufficiency and suggests that the low-dose be used only when cosyntropin is in short supply (ES [Bornstein 2016]).

Synacthen Depot [Canadian product]: IM: 1 mg administered as a single dose or once daily for 3 or 4 days (depending on method of testing; refer to manufacturer labeling for detailed information). Note: For patients with severe adrenal insufficiency, some clinicians administer dexamethasone on days that Synacthen Depot is administered to provide steroid coverage.

Therapeutic use: Synacthen Depot [Canadian product]: IM (Note: Titrate to lowest effective dose at the longest effective dosing interval): Initial for acute treatment: 1 mg daily for 3 days; maintenance dose is individualized: 0.5 to 1 mg every 2 to 3 days or twice weekly or 2 mg once weekly or less frequently

Transferring from corticosteroids: Synacthen Depot [Canadian product]: IM: Initial: 1 mg daily; gradually reduce steroid by 25% of original dose on successive days. Upon withdrawal from steroid adjust Synacthen Depot dose as needed.

Transferring from animal-derived ACTH: Synacthen Depot [Canadian product]: IM: Conversion varies depending on product previously used. Manufacturer suggests that patients previously receiving ACTH gel 40 units daily should receive Synacthen Depot 0.5 mg every other day; adjust dose based on response, preferably by extending the dosing interval.

Administration

IV: May administer by IV injection over 2 minutes or as an IV infusion over 4 to 8 hours. Synacthen Depot [Canadian product] should not be administered intravenously.

IM: May administer IM (reconstituted powder for injection only); cosyntropin injection solution is not recommended for IM administration (manufacturer recommendation).

Synacthen Depot [Canadian product]: Shake ampul until uniform appearance; administer by IM injection in the buttocks. Self-administration by patient is not recommended.
