RU-486 is a Mifepristone-based abortion pill manufactured by various pharmaceutical companies. This tablet blocks progesterone, a hormone essential for pregnancy maintenance. Mifepristone prepares the uterus for expulsion by stopping fetal development. Each strip contains 1 tablet of 200mg for single-use administration. The effects take a few hours to initiate and are followed by Misoprostol intake for completion. The peak action is observed within 24 to 48 hours. Many women use this as the first step in a medical abortion process.
