You may be confused about the difference between the abortion pill and Plan B. They have two completely different reasons for use. While the abortion pill terminates an existing pregnancy, Plan B works to prevent a pregnancy.
What is the Abortion Pill?
Known as medical abortion, the abortion pill consists of two different drugs that terminate an existing pregnancy. Mifepristone is the first drug, which blocks the womb from absorbing progesterone and prevents the embryo from implanting or growing in the uterus.
Secondly, misoprostol is taken to cause the uterus to contract and expel the pregnancy through the vagina. The FDA only recommends the abortion pill for women through 10 weeks pregnant or earlier.
