A medical abortion involves using medication to end an early pregnancy without surgical intervention, typically within the first 13 weeks. The safest and most effective method utilizes two medications: Mifepristone and Misoprostol. Both of these medications are listed among the essential medicines by the World Health Organization.
Mifepristone
Mifepristone works by blocking progesterone, a hormone necessary to maintain pregnancy. Without enough progesterone, the fertilized egg cannot properly attach to the uterine wall, leading to uterine contractions.
Misoprostol
Misoprostol assists in inducing contractions, facilitating the expulsion of pregnancy tissues from the uterus.
Combined Use
When used together, Mifepristone and Misoprostol have proven to be highly effective and safe for early first-trimester abortions. The procedure typically results in cramping and bleeding similar to a menstruation cycle. Some common side effects include nausea, vomiting, and diarrhea. Serious complications are very rare. Research indicates that medical abortion can be safely conducted at home, provided the woman has access to nearby emergency services or a hospital.
