Choosing an Emergency Contraceptive

There are two forms of emergency contraception: emergency contraceptive pills (the morning-after pill) or the IUD (intrauterine device). Choosing the correct one is dependent on several factors and the below questionnaire might be helpful in giving you an idea of the best option for you.

Emergency contraception

Emergency contraceptive pills are widely used across the world. Some are available over the counter, others on prescription only. Even if you think you are a 100% suitable to take an emergency contraceptive pill and want to buy it over the counter, a pharmacist or nurse will still ask you medical questions beforehand. The medical questions will help them determine if it is safe for you to take your chosen emergency contraceptive. If you feel uncomfortable visiting a pharmacist or nurse, you can order emergency contraception online, however it is important to bear in mind that the efficacy of emergency contraception is dependent on how soon you take it after unprotected sex.

The emergency contraceptive pill Levonelle is suitable if you can take it within 72 hours of having unprotected sex. If it's been more than 72 hours since you've had unprotected sex, then the alternative option is ellaOne, which can be taken up to 120 hours after unprotected sex. Both are more effective if taken as soon as possible after sex as possible. Neither is effective if you are already pregnant, and neither can be used as an on-going form of birth control or pregnancy prevention.

The IUD

An IUD is effective if inserted within 120 hours after unprotected sex has occurred. It may be more difficult to choose an IUD simply because insertion requires a medical procedure which can only be performed by a specially trained doctor.

The IUD is inserted in the uterus and works by releasing copper into the womb environment to influence the menstrual cycle. The main benefit of the IUD as emergency contraception is that once it has been inserted it can provide effective contraceptive cover for a number of years, depending on your individual situation. Although anybody can have the IUD fitted, it's mostly recommended to women who have already had children.

Intrauterine Device (IUD)

Which emergency contraceptive pill is better?

It is debatable whether Levonelle or ellaOne is better than the other. ellaOne does last for longer, and there is evidence that during the first three days after unprotected sex it can prevent marginally more pregnancies than Levonelle. However, ellaOne is a newer medication, and has therefore not undergone as many trials as Levonelle has.
