Ulipristal acetate (Ella) emergency contraception can be used up to how many days after unprotected sex?

• A. 3 days
• B. 5 days
• C. 7 days
• D. 10 days

Answer: (B)

Ulipristal acetate works by delaying ovulation, which can prevent fertilization if taken before the egg is released. Because it can effectively postpone ovulation later in the cycle, it has a longer usable window than some other options. It is approved for use up to five days (120 hours) after unprotected sex, making five days the correct timeframe. This makes it more flexible than the three-day window often cited for levonorgestrel emergency contraception, and well beyond simply a few days. Take it as soon as possible for the best chance of preventing pregnancy, but within five days of unprotected intercourse.
