    You can expect the following during a cosyntropin (Cortrosyn) stimulation test:
    • You will be lying down. A nurse and a technician will do the test.
    • Your blood pressure, temperature, and pulse will be checked.
    • The technician will draw a sample of blood from your arm.
    • The nurse will insert an intravenous catheter (IV) into your arm or hand. This IV will then be flushed with a small amount of saline.
    • A medicine called cosyntropin will be injected into the IV. This will take about one minute. During this injection, you may feel warm or flushed, or have a "butterfly" feeling in your stomach. Some people have an empty stomach feeling or slight nausea. These feelings go away in one to two minutes.
    • After the medicine is injected, the nurse will inject a small amount of saline again.
    • At 30 and 60 minutes after the injection of cosyntropin, the technician will draw a blood sample from your arm.
