Question

A 25-year-old woman attends the GP 4 hours after unprotected intercourse. She requests the most effective oral emergency contraception. Her cycle is regular at 28 days and her last menstrual period started 13 days ago (cycle day 13). She declines a copper IUD. Which oral method is most appropriate?

Accepted Answer

Ulipristal acetate 30 mg - it can delay ovulation even after the LH surge has begun, which is critical on cycle day 13

Answer

Levonorgestrel 1.5 mg - it is equally effective to UPA at this time point

Answer

Either method - timing in the cycle does not affect efficacy

Answer

Neither method is effective this close to ovulation

Answer

Levonorgestrel 3 mg (double dose) to improve efficacy near ovulation
