Emergency contraception exists for one reason. Sometimes things don't go to plan. And having access to a range of options is a very normal, legitimate part of reproductive healthcare.

That's why we're here to cut through the medical jargon and lay out what is available in Australia in 2026, how emergency contraception works, when it's used, and what to keep in mind when choosing between them. It's decision support, not medical advice or judgement — and it's designed to give you enough information to have a confident, informed chat with a pharmacist or GP.

You'll often hear emergency contraception called the 'morning after pill', but that nickname is misleading. In many cases, you have several days (not just overnight) to act. Emergency contraception is also not an abortion, and does not interrupt an existing pregnancy; it works before a pregnancy is established.

But it's important to remember not all options work the same way, or for the same amount of time.

So let's break down three key options: the levonorgestrel emergency contraceptive pill, ulipristal acetate emergency contraceptive pill ( EllaOne) and copper IUDs used as emergency contraception. We answer all your common questions so you can make an informed decision:

1. Levonorgestrel emergency contraceptive pill.

Levonorgestrel-based pills are one of the most familiar options in Australian pharmacies. They're typically a single tablet you take as soon as you can after unprotected sex or contraceptive failure.

How the levonorgestrel emergency contraceptive pill works.

Levonorgestrel is a synthetic version of the hormone progesterone. It works by delaying or preventing ovulation, essentially trying to stop your ovary releasing an egg so that sperm already in the reproductive tract can't fertilise it. It does not interrupt an established pregnancy and isn't an abortion pill.

When it can be used.

• Can be taken within 72 hours (three days) after unprotected sex.

• Effectiveness drops off the longer you wait; if it has been longer than 72 hours, speak to your doctor or pharmacist.

What you need to know.

Access: You can buy levonorgestrel emergency contraception over the counter at pharmacies, usually after a brief, private chat with a pharmacist.

Side effects: Some people notice nausea, a headache or a change in their next period (earlier, later, heavier or lighter than usual). These are usually short-lived.

Future contraception: It covers this specific incident; it doesn't provide ongoing contraception for the rest of your cycle.

Myths to clear up.

• "You must take it the next morning, or it won't work." The facts: The window is up to three days, but it is more effective the sooner you take it.

• "Using it will damage your fertility." The facts: There's no evidence that using levonorgestrel emergency contraception causes infertility.

• "It's basically an abortion." The facts: It works by delaying ovulation and doesn't interrupt an existing pregnancy.

2. Ulipristal acetate emergency contraceptive pill.

The other emergency contraceptive pill available in Australia contains ulipristal acetate and is sold under the brand name EllaOne. EllaOne is a single oral tablet and is currently the only ulipristal acetate emergency contraception pill on the Australian market.

How EllaOne works.

Ulipristal acetate, the active ingredient in EllaOne, is a selective progesterone receptor modulator. In simple terms, it tweaks how progesterone works in the body to delay or inhibit ovulation. 

It is not effective if ovulation has already occurred, and it does not interrupt an existing pregnancy. It's not an abortion pill and doesn't have a long-term effect on fertility.

When it can be used.

• Some emergency contraception pills are used within 72 hours; EllaOne can be taken up to 120 hours (five days) after unprotected sex or contraceptive failure.

• Like other options, taking it as soon as possible is still recommended.

What you need to know.

Access: In Australia, it's available from pharmacies over the counter after a pharmacist consultation to check timing, other medications and suitability.

Timing in your cycle: EllaOne is designed to delay ovulation even when you're closer to ovulation. ​​A pharmacist will ask about timing and other factors to help decide what option may be suitable for you.

Side effects: Some people notice nausea, a headache, breast tenderness, and a more painful period. These are usually short-lived.

Myths to clear up.

• "EllaOne can end a pregnancy that's already started." The facts: It cannot interrupt an existing pregnancy and is not used for abortion.

• "I think I've ovulated so emergency contraception won't help." The facts: While emergency contraception works by delaying or preventing ovulation, ovulation timing is hard to know for sure. It can happen earlier or later than expected, and sperm can survive in the body for up to 5 days. If ovulation timing is uncertain, EllaOne is an option.

3. Copper IUD as emergency contraception.

A copper IUD is a small, T‑shaped device that a trained clinician inserts into the uterus. It can be used as emergency contraception and, once in place, as long‑term contraception.

How a copper IUD works.

Copper is toxic to sperm and interferes with how sperm move and function. When used as emergency contraception, the copper IUD creates an environment that makes it very difficult for sperm to fertilise an egg. It does not interrupt an existing pregnancy and is not an abortion method.

When it can be used.

• A copper IUD can be inserted up to 120 hours (five days) after unprotected sex for emergency contraception.

• It is one of the most highly effective emergency contraception options available.

What you need to know.

Access: You need an appointment with a GP, nurse or clinic trained in IUD insertion, which can take more organisation than getting a pill from a pharmacy.

Procedure: Insertion is a brief procedure, but it's more invasive than taking a tablet and may cause temporary cramping or discomfort.

Ongoing contraception: Once inserted, a copper IUD can provide long‑term contraception for several years, which may be a major factor if you're also looking for a reliable, hormone‑free ongoing method.

Myths to clear up.

• "Using an IUD like this is basically the same as having an abortion." The facts: The copper IUD works by preventing fertilisation rather than ending an existing pregnancy.

• "You have to take it out straight after the emergency has passed." The facts: It can stay in place and act as your regular contraception if that suits you.

Your most common questions, answered.

Whichever option you're considering, it's likely you'll have similar questions.

Timing: All methods are more effective the sooner you use them. Levonorgestrel is generally used within 72 hours; EllaOne and copper IUDs can be used up to 120 hours (five days).

Access: Pills (levonorgestrel and EllaOne) are accessed through pharmacies without a prescription; a copper IUD requires a clinic visit and a healthcare professional trained on insertion.

Cost: Prices vary between pharmacies and clinics, and may be affected by things like concession status or private billing. If you're worried, you can ask about the price before you agree to go ahead.

Privacy: Pharmacists are used to having these conversations and can often step aside from the main counter if you'd prefer more privacy. Clinics follow standard confidentiality processes; you are entitled to ask for information in a way that feels as discreet as possible for you.

Emergency contraception is there for when you may need it and understanding the differences between your options can help you feel clearer about your next step.
