The abortion pill (medical abortion) can generally be taken up to around 70 days, or roughly 10 weeks, after the first day of your last menstrual period. This time frame is when the pill is most effective and typically recommended by healthcare providers. Beyond 10 weeks, the abortion pill is less commonly used and may require additional doses or alternative methods like surgical abortion. Medical abortion involves two medications: mifepristone, which blocks the hormone needed for pregnancy to continue, and misoprostol, which induces uterine contractions to expel the pregnancy. This method is most effective when used within the first 10 weeks. After 10 weeks of pregnancy, other abortion methods, such as surgical procedures, are often used. Some sources mention the possibility of medical abortion up to 12 weeks or even up to 24 weeks in very specific contexts, but these are less common and may depend on the laws and healthcare provider's guidance. In summary, the abortion pill is usually taken up to about 10 weeks of pregnancy, with some exceptions and follow-up care if needed beyond that period.
