Medical abortion (or abortion without surgery) is the interruption of an unwanted pregnancy without surgical intervention, but with the help of special medications.
Medical abortion can be performed up to 42-49 days from the first day of the last menstruation. The effectiveness of medical abortion is increased when it is carried out in the early stages. After 42-49 days, the efficiency of drug interruption of pregnancy is significantly reduced, which may lead to the need for other methods of abortion (vacuum aspiration, surgical abortion).
What happens in a medical abortion? After taking 600 mg of mifepristone, a process is started to direct the death of the fetus. Mifepristone binds to the receptors of progesterone, thereby blocking the action of the hormone, which stimulates the growth of the endometrium. In this case, the woman restores the sensitivity of the myometrium to the hormone oxytocin. Myometrium begins to shrink, which leads to the termination of pregnancy.
After 36-48 hours after taking mifepristone, a woman takes prostaglandins, under the influence of which the uterus begins to shrink, which leads to the expulsion of the fetus from her cavity.
Immediately after medical abortion, a woman should start using contraceptives, since a subsequent pregnancy can occur even before the appearance of a period.
It should be borne in mind that in sporadic cases after a medical abortion the pregnancy is not interrupted. And if the woman then decided not to interrupt the pregnancy, she should understand that the fetus may have some congenital pathologies when taking medications for medical abortion. In particular, cases of teratogenic effects of prostaglandins on the fetus are known.
