Description
Levonelle One Step is an emergency contraceptive pill (often called the “morning after pill” or “next day pill”) used to reduce the chance of pregnancy after unprotected sex or contraceptive failure (for example, a split condom or missed pill). It is intended for one-off, urgent use – not as regular contraception.
What Levonelle One Step Is
Levonelle One Step contains levonorgestrel 1500 micrograms in a single tablet. It is a well‑established form of emergency contraception used in the UK.
It should be taken as soon as possible after unprotected sex. The sooner it is taken, the better it tends to work. It is licensed for use up to 72 hours (3 days) after unprotected intercourse, but effectiveness declines with time.
How It Works (Mechanism of Action)
Levonorgestrel works mainly by delaying or inhibiting ovulation (the release of an egg). If ovulation is delayed, there may be no egg available for sperm to fertilise.
It may also make fertilisation less likely if ovulation has not yet occurred. It does not end an existing pregnancy and will not work if you are already pregnant.
How Effective Is It?
Emergency contraception is most effective when taken as soon as possible after unprotected sex. Levonelle One Step can be taken up to 72 hours, but its ability to prevent pregnancy reduces the longer you wait.
If more than 72 hours have passed, or if you are close to ovulation, a copper IUD (coil) is the most effective form of emergency contraception and can be fitted up to 5 days after unprotected sex (or up to 5 days after the earliest likely ovulation date).
When to Take Levonelle One Step
Take it urgently if:
- You had unprotected sex.
• A condom split, slipped, or was used incorrectly.
• You missed contraceptive pills or started a pack late.
• A patch or ring was off for too long.
• You had vomiting/diarrhoea that may have affected pill absorption.
• You are worried your usual contraception failed.
Timing matters
Take 1 tablet as soon as possible – ideally the same day. Do not delay waiting for symptoms.
Dosage and How to Use It
- Dose: One tablet (1500 micrograms) taken once.
• Swallow with water.
• You can take it with or without food.
If you vomit after taking it
If you vomit within 3 hours of taking Levonelle One Step, the dose may not have been absorbed. Seek medical advice urgently – you may need to take another tablet or use an alternative emergency contraceptive method.
Who Can Use It – Eligibility and Safety Notes
Levonelle One Step is used by many people safely, but it may not be suitable for everyone. An online consultation (or pharmacist/clinician assessment) is important to confirm it is appropriate for you.
It may be less suitable if:
- You are taking medicines that can reduce levonorgestrel effectiveness (see interactions below).
• You have severe malabsorption problems (for example, some inflammatory bowel conditions) that may reduce absorption.
• You have already taken emergency contraception earlier in the same cycle – you may need tailored advice.
• Your unprotected sex was more than 72 hours ago – consider a copper IUD.
Age
In the UK, people under 16 can still access emergency contraception, but assessment and safeguarding considerations apply. If you are under 16, seek advice from a pharmacist, GP, sexual health clinic, or an appropriate online service that can provide safe assessment.
Side Effects (What You Might Notice)
Most side effects are mild and settle within a short time. Possible side effects can include:
- Nausea
• Tiredness
• Headache
• Dizziness
• Breast tenderness
• Lower abdominal pain
• Changes to your next period (earlier, later, heavier, or lighter)
• Spotting or irregular bleeding
When to get urgent medical advice
Seek urgent help if you have:
• Severe lower abdominal pain (especially 3-5 weeks after taking it) – this could be a sign of ectopic pregnancy.
• Fainting, severe dizziness, or shoulder tip pain.
• Heavy bleeding that soaks through pads rapidly or lasts unusually long.
• Signs of an allergic reaction (swelling, difficulty breathing, widespread rash).
Interactions and Medicines That Can Reduce Effectiveness
Some medicines and herbal remedies can make Levonelle One Step less effective by increasing how quickly levonorgestrel is broken down. Tell the clinician/pharmacist if you take any regular medication.
Common examples include certain anti‑epileptic medicines, some HIV treatments, rifampicin/rifabutin (antibiotics used for specific infections), and St John’s wort. If you use any of these, a copper IUD is usually recommended as the most reliable emergency option.
What to Do After Taking Levonelle One Step
Use contraception for the rest of this cycle
Levonelle One Step does not protect you from pregnancy from sex later in the same cycle. Use condoms until your next period and restart/continue regular contraception according to professional guidance.
Pregnancy test guidance
Take a pregnancy test if:
• Your period is more than 7 days late.
• Your next period is unusually light or unusual for you.
• You have pregnancy symptoms.
• You are concerned for any reason.
STI protection
Emergency contraception does not protect against sexually transmitted infections (STIs). If you think you might be at risk, consider an STI test and speak to a sexual health clinic.

Frequently Asked Questions (10)
How soon should I take Levonelle One Step?
Take it as soon as possible after unprotected sex. It can be used up to 72 hours (3 days), but it is generally more effective the sooner it is taken.
Can I buy Levonelle One Step online in the UK?
Yes, many UK services offer Levonelle One Step after an online consultation to confirm it is safe and suitable, with discreet delivery options.
Does Levonelle One Step cause an abortion?
No. Levonelle One Step is not an abortion pill. It works mainly by delaying ovulation and does not end an existing pregnancy.
Will it work if I have already ovulated?
It may be less effective if ovulation has already happened. If you think you are close to ovulation or it’s been over 72 hours, a copper IUD is the most effective emergency option.
What if I vomit after taking it?
If you vomit within 3 hours, the tablet may not have been absorbed. Seek urgent advice – you may need another dose or a different emergency method.
Can I take it more than once in the same month?
It can be taken more than once if needed, but it is not ideal as regular contraception. Repeated use can cause irregular bleeding. Consider reliable ongoing contraception.
Will it affect my next period?
It can make your next period come earlier or later and may change flow. If your period is more than 7 days late, take a pregnancy test.
Does it protect me for the rest of the cycle?
No. It only helps with the unprotected sex that already happened. Use condoms until your next period and follow advice for restarting your regular contraception.
Are there medicines that stop it working properly?
Yes. Some medicines (and St John’s wort) can reduce effectiveness. If you take interacting medicines, a copper IUD is usually recommended.
When should I seek urgent help after taking it?
Get urgent help for severe lower abdominal pain (especially 3-5 weeks later), very heavy bleeding, fainting, or signs of an allergic reaction.
