Abortion pill or abortion tablet is the common name for using two different medicines called Mifepristone and Misoprostol to end an unwanted pregnancy. Pregnancy needs a hormone called progesterone to grow normally, and mifepristone blocks progesterone, stopping the pregnancy from growing.
However, pregnancy until 8-9 weeks can only be removed using these medicines. Once the pregnancy exceeds nine weeks, medical abortion fails, or miscarriage becomes incomplete, surgery is used to terminate the pregnancy altogether.
