Serious side effects such as very heavy vaginal bleeding or severe or life-threatening infection can occur in a few patients when mifepristone is used to end a pregnancy. In a small number of patients, mifepristone may not end the pregnancy. If this happens, you may need to have surgery to end your pregnancy. If mifepristone does not end the pregnancy and you do not have surgery to end the pregnancy, there is a risk of birth defects in the baby.Tell your doctor if you have or have ever had bleeding problems, an ectopic pregnancy ('tubal pregnancy' or pregnancy outside the uterus), anemia (less than normal number of red blood cells), or if you are taking anticoagulants ('blood thinners') such as warfarin (Coumadin), heparin, or aspirin. If you experience very heavy vaginal bleeding after treatment with mifepristone, such as soaking through two thick full-size sanitary pads every hour for two continuous hours, call your doctor immediately or seek emergency medical care. You also should call your doctor immediately or seek emergency care if you experience fever greater than 100.4°F that lasts for more than 4 hours, severe pain or tenderness in the area below the waist, chills, a fast heart beat, shortness of breath, dizziness, fainting, or blurred vision after treatment with mifepristone.

Mifepristone is used alone or in combination with misoprostol (Cytotec) to end an early pregnancy. Early pregnancy means it has been 49 days or less since your last menstrual period began. Mifepristone is in a class of medications called antiprogestational steroids. It works by blocking the activity of progesterone, a substance your body makes to help continue pregnancy.
How should this medicine be used:
Mifepristone comes as a tablet to take by mouth. It should be taken only in a clinic, medical office, or hospital under the supervision of a qualified doctor. You will take three tablets of mifepristone at one time on the first day. Two days later you must go back to your doctor. If your doctor is not certain that your pregnancy has ended, you will take two tablets of another medication called misoprostol. You may have vaginal bleeding for 9 to 30 days or longer. If your bleeding is heavy, you should call the emergency contact number. Fourteen days after taking mifepristone, you must go back to your doctor for an exam or ultrasound to make sure that the pregnancy has ended. Take mifepristone exactly as directed.
Other uses for this medicine:
Mifepristone is also sometimes used to end pregnancies that are greater than 49 days since your last menstrual period; as an emergency contraceptive after unprotected sexual intercourse ('morning-after pill'); to treat tumors of the brain, endometriosis (growth of uterus tissue outside the uterus), fibroids (noncancerous tumors in the uterus); or to induce labor (to help start the birth process in a pregnant woman).
