Types of Emergency Contraception: Pills, IUDs, and Their Effectiveness

World Contraception Day, celebrated on September 26 every year, aims to raise awareness about contraception and reproductive health. It serves as an important reminder to understand the importance of accessing various forms of contraception.

Emergency contraception (EC) is a crucial part of this conversation as it offers a safety net when things don’t go as planned. At Pearl Chemist Group, we’re committed to ensuring you can access emergency contraception when you need it the most.

This blog covers everything you need to know about emergency contraception options. But, first, let’s start with the basics.

What is emergency contraception?

After unprotected sex or contraceptive failure, EC serves as a form of birth control to prevent pregnancy. Its primary purpose is to lower the risk of unwanted pregnancy when regular methods, like condoms or birth control pills, are unavailable or ineffective.

There are two main types of emergency contraception: pills and intrauterine devices (IUDs). Each method has its unique mechanism and effectiveness, tailored to different needs and circumstances.

Why is emergency contraception important?

Emergency contraception is an effective option for preventing unintended pregnancies. Here’s why it is so important:

1. Reduces Unplanned Pregnancies: EC prevents pregnancy after unprotected sex or contraceptive failure (e.g., a condom breaking). It provides a vital second chance to avoid pregnancy, which can be especially important for those who might not be ready for parenthood.

2. Protects Against Contraceptive Failure: No contraceptive method is 100% foolproof. Emergency contraception acts as a safety net when other methods fail, such as missed birth control pills.

3. Timely Intervention: After unprotected sex, you should use EC within a specific timeframe—up to 72 hours for the most common types (levonorgestrel) and up to 120 hours for others (ulipristal acetate). Taking it sooner enhances its effectiveness.

4. Supports Reproductive Choice: Access to emergency contraception promotes reproductive autonomy by allowing women to make decisions about their bodies and the future. It empowers women to take charge of their reproductive health, helping them avoid circumstances that could compel them to make difficult decisions in the future.

5. Prevents Health Risks: Unplanned pregnancies can pose significant physical, emotional, and economic challenges. By preventing unintended pregnancies, EC reduces these risks and promotes overall well-being.

What is important to understand about emergency contraception pills?

What are emergency contraception pills?

Emergency contraception pills (ECPs) are oral medications designed to prevent pregnancy after unprotected intercourse. Levonelle and ellaOne are the two primary types of ECPs available in the United Kingdom. Levonelle, better known as the "morning-after pill," contains levonorgestrel, while ellaOne contains ulipristal acetate. Both pills are effective in preventing pregnancy but differ in their timing and mechanism.

How do emergency contraception pills work?

EC pills disrupt the normal process of ovulation, preventing the release of an egg from the ovary. If fertilisation does occur, it may even alter the lining of the uterus, making it less suitable for implantation. Taking these pills soon after unprotected sex determines their effectiveness.

Emergency contraception pills are effective.

The effectiveness of these pills varies depending on several factors, including timing, dosage, and individual health. When taken within 72 hours, Levonelle is approximately 89% effective, whereas ellaOne can be up to 98% effective if taken within 120 hours.

When to use EC pills?

Take these pills as soon as possible after unprotected sex to maximise their effectiveness. You can obtain ECPs from pharmacies, clinics, or through your healthcare provider. A pharmacist's consultation can help you determine the best option for you and ensure that you receive the appropriate guidance and support.

Everything you need to know about emergency contraception IUDs

What are emergency contraception IUDs?

The copper IUD, also known as the intrauterine device, is a highly effective form of emergency contraception. A healthcare professional inserts the copper IUD into the uterus, unlike ECPs, and it can prevent pregnancy for up to five years. It is a non-hormonal option that works by creating an environment in the uterus that is inhospitable to sperm, preventing fertilisation.

How does an IUD work?

The copper IUD prevents pregnancy by releasing copper ions into the uterus, which impair sperm mobility and viability. It also alters the uterine lining, making it less likely for a fertilised egg to implant. The copper IUD is a highly effective emergency contraception method, with a failure rate of less than 1%.

IUDs' effectiveness

The copper IUD is one of the most effective forms of emergency contraception available. Its effectiveness surpasses that of emergency contraception pills, with a failure rate of less than 1%. If desired, you can leave it in place for ongoing contraception, providing long-term protection against pregnancy.

When to use an IUD?

A healthcare professional must insert the copper IUD within five days of unprotected sex for it to be effective. If you are considering this option, it is essential to consult with a healthcare provider who can guide you through the process and ensure proper placement.
