Why It Matters

The Supreme Court's pending decision on mifepristone access could restrict or eliminate the ability to receive the drug by mail, potentially forcing patients to rely on alternative, off-label medication regimens like misoprostol.

Key Facts

  • The Fifth Circuit Court of Appeals blocked an FDA rule allowing telemedicine prescriptions for mifepristone.
  • Supreme Court Justice Samuel Alito issued a stay on the Fifth Circuit's ruling until May 11.
  • Nearly 30 percent of abortions in the US currently occur via telemedicine.
  • Almost two-thirds of abortions in the US are performed using medication.
  • Louisiana passed a 2024 law reclassifying mifepristone and misoprostol as controlled substances.
  • Mifepristone works by blocking progesterone to halt pregnancy growth.
  • Misoprostol works by causing uterine contractions to expel pregnancy tissue.
  • Misoprostol is currently used off-label for abortion, labor induction, miscarriage management, and postpartum hemorrhage.
  • Ibis Reproductive Health is conducting the first head-to-head clinical trial comparing the two-drug regimen to misoprostol alone.
