Emergency Contraceptive Pill (ECP)

Emergency Contraceptive Pill (ECP) in New Zealand

Contraceptive failure or unprotected sex can be a stressful experience — and sometimes getting to a doctor isn't possible. At Corner Pharmacy, an accredited pharmacist is available for a quick, confidential consultation so you can get the support you need, when you need it most.

We're open evenings and weekends at many locations, making it easy to access this service at a time that works for you.


What Is the Emergency Contraceptive Pill?

The emergency contraceptive pill (ECP) — also known as the morning-after pill or Plan B — is available without a prescription at Corner Pharmacy in New Zealand. It's a safe, effective option for preventing pregnancy after unprotected sex or contraceptive failure.

The ECP is not an abortion pill and will not work if you are already pregnant. If pregnancy does occur, there is no evidence that taking the ECP will harm the baby.


How Does the Morning-After Pill Work?

The ECP works by preventing or delaying ovulation (the release of an egg). It may also make it harder for sperm to reach the egg, or prevent a fertilised egg from attaching to the uterine wall.

It is most effective when taken as soon as possible after unprotected sex, and can be used up to 72 hours (and in some cases up to 4 days) afterwards.


How Effective Is the ECP?

Effectiveness decreases over time, so acting quickly matters:

  • Within 24 hours: approximately 95% effective
  • 25–48 hours: approximately 85% effective
  • 49–72 hours: approximately 58% effective

Beyond 72 hours, the ECP is less effective and is not recommended.

Note: If you weigh more than 70kg, the pill may be less effective. In this case, a copper IUD is recommended — or if you choose the ECP, taking two pills is advised. Talk to our pharmacist for personalised guidance.


When Should I Take the Morning-After Pill?

Take the ECP as soon as possible after unprotected sex — ideally within 24 hours, and no later than 72 hours (three days). The emergency contraceptive pill does not protect against sexually transmitted infections (STIs).


Are There Side Effects?

The ECP is generally safe. Some people may experience:

  • Nausea or vomiting
  • Fatigue
  • Headaches
  • Breast tenderness
  • Spotting or changes to your next period
  • Abdominal pain or cramping

If vomiting occurs within 3 hours of taking the pill, it may not have been absorbed — you may need another dose. Serious side effects are rare, but seek medical help immediately if you experience severe abdominal pain, difficulty breathing, or swelling.


What Will the Pharmacist Ask?

Before supplying the ECP, our pharmacist will have a brief, private conversation with you. This typically covers:

  • Your current method of contraception
  • The reason you're seeking emergency contraception
  • How long it has been since unprotected sex
  • Details about your period, including any irregularities
  • Any relevant medical conditions (e.g. unexplained vaginal bleeding, Crohn's disease, history of ectopic pregnancy)
  • Current medications — prescription, over-the-counter, or supplements
  • Any symptoms such as unusual discharge, lower abdominal pain, or pain during sex

This helps ensure the ECP is the right option for you and safe to use given your individual circumstances.


What Type of ECP Is Available in NZ?

In New Zealand, the emergency contraceptive pill contains levonorgestrel — the same medication known as Plan B in the USA or Levonelle in the UK. It's a well-established, widely used emergency contraceptive with a strong safety record.
