Is emergency contraception required after the Mifepristone mistake?

Question

Hello doctor,

I accidentally took Mifepristone thinking it was an emergency contraceptive three to four days after unprotected sex. Should I take an actual emergency contraceptive, or should I avoid taking any more medication? What should I do next? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Mifepristone is not the same as an emergency contraceptive. If you took a low dose (10 to 25 mg), it might have some contraceptive effect, but its effectiveness is not well studied compared to regular emergency contraceptives.

If you took the 200 mg dose (which is used for medical abortion), it is unlikely to work effectively as emergency contraception and may cause irregular bleeding, nausea, or abdominal cramps.

What you should do next:

If you are still within 72 hours of unprotected sex, you can take a regular emergency contraceptive such as Levonorgestrel or Ulipristal Acetate to maximize protection.
If more than 72 hours but less than five days have passed, you may consider a copper intrauterine device (IUD) for emergency contraception, which requires a consultation with a doctor.
If more than five days have passed, emergency contraception will no longer be effective. If you miss your next period, take a urine pregnancy test to confirm pregnancy. If positive, consult a gynecologist or obstetrician for appropriate medical guidance, including prescribed abortion medication if necessary.

I hope this helps.
