Cosyntropin is a man-made form of a hormone called adrenocorticotropic hormone (ACTH). ACTH is a hormone that is normally produced by the pituitary gland in the brain. ACTH stimulates the adrenal glands to release the hormones cortisol and adrenaline. These hormones help your body respond to stress and also support many systems of the body including circulation, metabolism, immunity, and the nervous system.

Cosyntropin is used as part of a medical test called an ACTH stimulation test. This test can help your doctor diagnose adrenal gland disorders such as Addison's disease, Cushing syndrome, or hypopituitarism (failure of the pituitary gland to produce hormones correctly).

Cosyntropin may also be used for purposes not listed in this medication guide.
