In patients with a history of allergic reactions, monitor for hypersensitivity response (wheezing, rash or hives, and erythema) Cosyntropin is less likely than ACTH to cause such a response. Lab Test Considerations: Plasma cortisol concentrations will be measured before and 30 or 60 min after administration of cosyntropin. Therapeutic response is a rise in the plasma cortisol of at least 7 mcg/dL above baseline or a final concentration of at least 18 mcg/dL.
