Medical Termination of Pregnancy
What is a medical abortion?
A medical abortion is a procedure in which procedure is used to end a pregnancy. It does not require surgery and is performed through the ninth week of pregnancy. It involves taking two drugs — mifepristone and misoprostol. Mifepristone drug works by blocking the hormone progesterone and without it pregnancy cannot continue to grow in the uterus. Misoprostol drug causes cramping and bleeding to empty the uterus.
Some differences between the different types of abortions include:
- Medical abortions: A woman will take two different medicines (usually within a 48-hour period). The medication is given by a healthcare provider and is either taken in the provider’s office or at home (or a combination of both).
- Surgical abortions: In this type of abortion, a healthcare provider will surgically remove the embryo from the uterus. These types of abortions require mild sedation, local anesthesia or general anesthesia.
