This medication is used to control high blood sugar in people who have a certain condition (Cushing's syndrome), and who have failed surgery or cannot have surgery to correct the condition. Cushing's syndrome is caused by the body producing too much of a certain hormone (cortisol) which can cause glucose intolerance or type 2 diabetes. Mifepristone works by blocking the effects of cortisol.

Mifepristone may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using mifepristone, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using mifepristone safely.
Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
