In preparation for an abortion, a pelvic examination might be done to confirm the size of the uterus. Laboratory studies will rule out anemia , determine the woman's Rh factor , and screen for sexually transmitted diseases . Education about the procedure should be offered, and psychological support should be given as needed. Methotrexate is generally given by injection, but it also can be taken orally. Methotrexate stops the fertilized egg from implanting in the uterine lining during the first few weeks after conception.
Mifepristone works by blocking the female hormone progesterone.
As a result, the lining of the uterus breaks down and is passed out of the uterus through the cervix. Misoprostol is given by tablets that are either swallowed or inserted into the vagina. It causes uterine contractions and expulsion of the fetus through the vagina. A medical abortion can take from 3 days to 3 to 4 weeks. Some women will have vaginal bleeding after the first medication.
