Correct answer: C — Copper intrauterine device

The best answer is “Copper intrauterine device”. Hepatic enzyme induction can reduce the effectiveness of oral emergency contraception. A copper intrauterine device is the most effective emergency method and is not compromised by carbamazepine. If an intrauterine device is declined or unsuitable, specialist guidance governs the available oral alternative; ulipristal should not be improvised at double dose.
