How does it works Mifepristone powder

Mifepristone powder was used for the 10th week of pregnancy (70 days after the last day of the menstruation). It will stop your natural substance (progesterone) needed for pregnancy to continue. It is usually used with another drug called misoprostol. To make sure that you are in an appropriate location when you take misoprostol because vaginal bleeding, cramps, nausea, and diarrhea usually begins within 2 to 24 hours after taking it but could begin within 2 hours. Vaginal bleeding or spotting usually lasts for 9 to 16 days but can last for 30 days or longer. You must go back to your doctor for an exam or ultrasound 7 to 14 days after taking Mifepristone powder to confirm that the pregnancy has ended and to check the amount of bleeding. Take Mifepristone powder exactly as directed.
