MIFEPRISTONE (mi FE pri stone) treats high blood sugar (glucose) in people with Cushing Syndrome, a condition that occurs when the body releases too much of the hormone cortisol. Cortisol helps your body respond to stress in many ways, including by telling your body to release more sugar into the body for energy. This medication works by reducing the effects of cortisol in your body, which decreases your blood sugar.
