OBG · Contraception: emergency contraception

Sample item

Which is the most effective method of emergency contraception?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Copper IUCD insertion within 5 days

The copper IUCD is over 99 per cent effective as emergency contraception and provides ongoing protection. Levonorgestrel 1.5 mg is effective within 72 hours (up to 120 hours with declining efficacy), and ulipristal 30 mg works up to 120 hours.

Option by option

  • A. Combined pills (Yuzpe)

    The Yuzpe regimen is the least effective.

  • B. Levonorgestrel 1.5 mg

    Levonorgestrel is less effective and time-limited.

  • C. Ulipristal acetate

    Ulipristal is more effective than levonorgestrel but less than a copper IUCD.

  • D. Copper IUCD insertion within 5 days (correct)

    Correct. Copper IUCD is most effective.
