The procedure usually requires three office visits. On the first visit, the patient is given pills, Mifepristone, to cause the death of the embryo. At the second office visit, if the abortion has not occurred, she is given a second drug, Misoprostol, that causes cramps to expel the embryo. The last visit is for a follow-up ultrasound to determine if the procedure is complete. If the patient is still pregnant, a surgical procedure will be required.
