Emergency Contraception Within 120 Hours (5 Days)
Quick Answer
Only ulipristal acetate (Mifestad) is effective at this point, with approximately 85% effectiveness. This is your last window for pill-based EC.
Your One Option: Mifestad
At this timing (72-120 hours), **only ulipristal acetate (Mifestad)** is effective: - Levonorgestrel (Postinor): **Not recommended** beyond 72 hours - Ulipristal acetate (Mifestad): **85% effective** at 120 hours Mifestad is your last window for pill-based emergency contraception.
Why Mifestad Works Longer
Mifestad (ulipristal acetate) works differently than Postinor:
1. Different mechanism: Mifestad can delay ovulation even when the LH surge has begun
2. Longer effectiveness: Maintains protection for up to 5 full days
3. Proven efficacy: Clinical trials show 85% effectiveness at 120 hours
This makes it the only pill option when 3+ days have passed.

Order MifestadFrequently Asked Questions
Yes. 85% effectiveness means that of 100 people who would have gotten pregnant, 85 won't. This is still substantial protection, especially compared to no EC at all.
EC pills are not effective beyond 120 hours. A copper IUD may still work (up to 5 days after ovulation). Consult a healthcare provider about your options.
Levonorgestrel's effectiveness drops significantly after 72 hours. Studies show it provides minimal protection beyond this point, which is why Mifestad is the recommended option.
