What is Emergency Contraception?

Emergency contraception is a method used to prevent pregnancy after unprotected sex or contraceptive failure, such as a missed pill or a broken condom. It is most effective when taken as soon as possible after intercourse. There are two main types: emergency contraceptive pills (such as the morning-after pill) and the copper intrauterine device (IUD). These methods work by delaying ovulation or preventing fertilisation, offering a safe and effective way to reduce the risk of unintended pregnancy.

When Should You Take Emergency Contraception?
Emergency contraception should be taken as soon as possible after unprotected sex for the best chance of success. Some pills can be effective up to 72 hours after intercourse, while others work for up to 120 hours (five days). The copper IUD, when inserted by a healthcare professional, can also be used within five days and offers ongoing contraception. Timing is crucial, so seeking advice quickly is recommended.
Types of Emergency Contraception Available
There are two main types of emergency contraception: hormonal pills and the copper IUD. The most common pills include Levonorgestrel (available over the counter) and Ulipristal Acetate (available with a prescription). These work by delaying ovulation, preventing fertilization. The copper IUD, inserted by a doctor or nurse, prevents sperm from fertilizing an egg and can be used as long-term contraception. A pharmacist or healthcare professional can help determine the best option for you.
Effectiveness of Emergency Contraception
The effectiveness of emergency contraception depends on the type used and how quickly it is taken. Levonorgestrel is most effective within 72 hours, while Ulipristal Acetate remains effective up to five days. The copper IUD is the most effective method, with a success rate of over 99%. Although emergency contraception reduces the risk of pregnancy, it does not guarantee prevention, so using regular contraception is advised.
Does Emergency Contraception Have Side Effects?
Like any medication, emergency contraception may cause side effects, but these are usually mild and short-lived. Some people experience nausea, headaches, dizziness, or changes in their menstrual cycle. The copper IUD may cause heavier periods or cramping initially. If side effects persist or you experience severe discomfort, seeking medical advice is recommended.

Who can I speak to you?
If you need emergency contraception, a pharmacist, doctor, or sexual health clinic can provide confidential advice and support. Many pharmacies offer emergency contraception without the need for an appointment, ensuring quick and easy access. If you're unsure which option is right for you, speaking to a healthcare professional can help you make an informed decision.
