The abortion pill, known as medication abortion using mifepristone and misoprostol, is typically effective up to around 10 weeks (70 days) from the first day of the last menstrual period, according to FDA guidelines. Beyond this, effectiveness drops, and other organizations like WHO extend safe use to 12 weeks, while some protocols allow up to 24 weeks off-label or in specific regions.

Official Guidelines

FDA approves mifepristone up to 10 weeks gestation, with studies showing 87-99% effectiveness depending on timing and dosage. ACOG and Guttmacher support off-label use later by experienced providers, but surgical options are recommended after 10-13 weeks.

Variations by Region

In the UK, NHS and RCOG allow medical abortion up to 24 weeks in some cases. Access varies by U.S. state laws post-2022 rulings, with telehealth options in many areas.

Process Timeline

  • Day 1 : Take mifepristone orally at clinic or home.
  • 24-48 hours later : Misoprostol buccally, vaginally, or sublingually; cramping/bleeding starts 1-4 hours after.
  • 7-14 days : Follow-up to confirm completion.

Always consult a healthcare provider for personalized advice, as gestational age must be confirmed via ultrasound first.

TL;DR : Up to 10 weeks per FDA; later possible but consult a doctor.
