Unwanted Kit 1's contains Mifepristone and Misoprostol. Mifepristone works by blocking the effect of progesterone (female hormone), needed to maintain a pregnancy. In the absence of progesterone, the lining of the uterus breaks down as it does every month during the menstrual cycle, and the growth of pregnancy is stopped. It takes approximately 24-48 hours for Unwanted Kit 1's to show effect. Once it starts acting, you will experience uterine bleeding. But no uterine bleeding does not mean that the abortion is complete. On the other hand, second medicine is Misoprostol, that is a prostaglandin analogue, which helps in increasing the uterine contractions and relaxing the cervix. Thus Together Unwanted Kit 1's terminates the state of pregnancy. Misoprostol should be taken at least 24-36 hours after taking mifepristone either orally or vaginally. This is a non-surgical method which is 90% successful.
