Ulipristal acetate can be used up to how many days after unprotected intercourse?

• A. 24 hours.
• B. 48 hours.
• C. 72 hours.
• D. 96 hours.

Answer: (C)

Ulipristal acetate works by delaying ovulation, so its usefulness depends on where you are in the cycle. Its approved window after unprotected intercourse is up to five days (120 hours), with the highest effectiveness when taken before ovulation. This extends beyond older options like levonorgestrel, which is typically used up to 72 hours. The choices given in this question only go up to around four days, which is why the selected answer reflects a three-day mark in that limited set. In real practice, UL can be used up to five days after intercourse for the best chance of preventing pregnancy.
