What is Levonelle?

Levonelle (also known as Levonelle 1500 or Levonelle One Step), is a form of emergency contraception, or 'morning after pill'. It is one tablet that can be taken up to 72 hours after unprotected sex or failed contraception to prevent pregnancy. Levonelle is up to 95% effective, but the effectiveness diminishes over time, so it is important to take it as soon as possible. You can buy Levonelle online with free next-day delivery from euroClinix.

How does Levonelle work?

During the menstrual cycle, a mature egg is released from the ovaries. When this happens, the ovary produces progesterone, a female sex hormone that prevents the release of further eggs. Levonelle's main ingredient, levonorgestrel, tricks the body into believing that ovulation has already occurred by making high levels of synthetic progesterone. This prevents the release of further eggs from the ovaries. This is a similar method to the way combined pill and mini pills work.

Levonorgestrel also thickens the natural mucus in the womb, making it more difficult for sperm to reach the womb. This makes it less likely for an egg to be fertilised.

Levonelle is:

  • 95% effective when taken during the first 12 hours after unprotected sex
  • 85% effective when taken 12-24 hours after unprotected sex
  • 75% effective when taken 24-48 hours after unprotected sex
  • 58% effective when taken 48-72 hours after unprotected sex

Why is Levonelle effective for 72 hours?

The entire progression from fertilisation to implantation inside the womb can take up to three days, which is why Levonelle can only prevent pregnancy from occurring for up to 72 hours after unprotected sexual intercourse. The quicker you take it after unprotected sexual intercourse, the more effective it will be.

How to take Levonelle

Levonelle comes in the form of one tablet. You should take it as soon as possible, as the effectiveness decreases over time.

This morning after pill can be taken at any stage of the menstrual cycle.

If you are already taking birth control pills, you should continue to take them after you’ve taken emergency contraception, as Levonelle cannot be used twice during a menstrual cycle. It is recommended to use a barrier contraceptive such as a condom until your next cycle starts to protect against pregnancy.

If you experience severe vomiting or diarrhoea within two hours of taking the medication, you should take another one immediately. You can order another pack at the same time if you are worried about this.

You need to be 18 years or older to buy this treatment online in the UK. If you are 16 or younger, you will need to consult your doctor first, or visit your local family planning clinic or NHS Walk-in Centre.

Levonelle dosages

Levonelle is a simple one step tablet containing 1.5mg of the synthetic progesterone levonorgestrel. This is the only dosage of Levonelle available and is proven to be up to 95% effective at preventing pregnancy.

What precautions should I take?

You should not take Levonelle if:

  • you have severe liver problems
  • you have a bowel disease that may inhibit absorption of the treatment
  • you have a history of ectopic pregnancy
  • you have a history of inflammation in the fallopian tubes
  • you are allergic to any of the ingredients

Do not take this treatment if you are already pregnant. If you think you may be pregnant, if your last period was over five days late or unusually light or uncomfortable, or if you had unprotected sex over three days ago, you should inform your doctor, as you may already be pregnant. This treatment cannot terminate a pregnancy.

Levonelle should not be used as a regular method of contraception. If it is used twice in the same menstrual cycle it may not be as effective.

You should always inform your doctor about any other medications or supplements you are currently taking, even if they are not prescribed, as some may prevent Levonelle from working properly. Always follow your doctor’s advice when taking any medication.

Levonelle side effects

As with all prescription medications, Levonelle can cause some side effects, although not everyone will experience them. Because Levonelle only contains one hormone, progestogen, you may be less likely to get side effects.

The most common side effects include:

  • Nausea
  • Irregular bleeding between periods
  • Lower abdominal pain
  • Tiredness
  • Headache

Side effects should not last very long after treatment. If they persist or become more serious, consult a doctor for further advice.

A more detailed description of all reported side effects can be found on the patient information leaflet supplied with the medication, and can also be downloaded on this page.

Will Levonelle delay my period?

Emergency contraception may make your next period later or earlier than expected by a few days, and may cause bleeding or spotting before your period. However, if your period is late or substantially heavier or lighter than usual, you should consult a doctor.

Where can I buy Levonelle online?

You can buy Levonelle online from euroClinix if you are 18 years or older. Simply complete a short online consultation, which will be checked by one of our doctors to make sure you are suitable for this treatment. Your treatment will then be dispatched from our pharmacy with free next-day delivery on any orders made before 4.30pm.

You can purchase Levonelle online for future use. You can also purchase an extra pack in case of stomach upset after taking a pill. A maximum of four emergency contraception pills can be bought in a 12 month period.

Note: You must complete a short online consultation so that our doctor can ensure that the treatment is suitable for you. The above pricing should only be used as a reference. The final decision to issue this treatment lies with the prescribing doctor.
