Without asking for any professional advice, is a description of a medicine written about in a novel I read true (I'd like to know)?

misoprostol: drug used to start labor, used in conjunction with mifepristone, it’s effective in bringing about abortion in the second trimester of pregnancy. Taken by mouth, it’s safe to use until the 49th day of pregnancy, after which it brings serious risks for the mother.
