Levonelle FAQs

What are the benefits?

Levonelle, or 'the morning after pill', can be taken up to three days (72 hours) after unprotected sex to prevent pregnancy. The earlier you take this medication, the more likely it is to work. If you take it during the first day after unprotected sex, it is 95% effective. If taken between 25 to 48 hours after unprotected sex its effectiveness drops to 85%, which still gives you a strong chance of not falling pregnant.

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 hormone which prevents the release of further eggs. Levonelle One Step's main ingredient, levonorgestrel, tricks the body into believing that ovulation has already occurred by making high levels of synthetic progesterone. The production of this hormone prevents the release of further eggs from the ovaries.

Levonorgestrel also thickens the natural mucus in the womb, making it more difficult for sperm to enter the womb through the vagina. The less chance the sperm has to survive or reach the womb, the less likely it is that the egg will be fertilised.

The entire progression from fertilisation to implantation inside the womb can take up to 3 days, therefore the morning after pill 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.

Estimates reveal that 84 per cent of pregnancies will be stopped if this birth control method is taken within 72 hours of unprotected sexual intercourse. The pill is more efficient at stopping pregnancy the earlier you take it, meaning it’s important to take it as soon as possible after unprotected sexual intercourse, as opposed to delaying it to the third day.

Who can buy Levonelle online?

You have to be 18 years or older to buy this treatment online. 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.

Who shouldn't take this medication?

You should not take Levonelle if you are allergic to progestogen or levonorgestrel. Do not take this medication if you have liver disease or if you have a disease of the bowel or gut which causes malabsorption. This medication can also react negatively to fungal infection medications, as well as herbal medications containing St John's Wort.

This treatment may make your next period later or earlier than expected by a few days. If your next period after taking this treatment is over 7 days late, or is irregular in any way, you should inform your doctor or healthcare provider for a pregnancy test.

Do not take this treatment if you are already pregnant. If you think you may be pregnant, if your period is late or is your last period was over 5 days late or unusually light or uncomfortable, you should inform your doctor, as you might already be pregnant. If you take this treatment while you are pregnant, it will not prevent the pregnancy.

How do I take Levonelle One Step?

This morning-after pill can be taken at any stage of the menstrual cycle; swallow one tablet with water as soon as possible after unprotected sex. If you are already taking birth control tablets, you should continue to do so as this emergency contraceptive can only be used once during a single menstrual cycle. A barrier contraceptive such as a condom is still recommended for use when having sex to ensure against pregnancy until your next cycle starts.

If you begin to feel sick within 2 hours of taking the medication, you should take another one immediately. You should inform your doctor, pharmacist or healthcare provider for advice and to obtain another tablet.

Are there any side effects?

Most women do not experience side effects as Levonelle 1500mg tablets contain only one hormone, progesterone, which means you are less likely to feel unwell than with earlier versions of the morning after pill. Its shorter active time also means you are less likely to suffer side effects than with ellaOne.

Reported Levonelle side effects include headaches, stomach pain, diarrhoea and fatigue. Your period may also come later after taking this medication, which may cause some spotting or bleeding before your next period.

"Morning-after pills can be used to prevent pregnancy in the event of an emergency or where your normal contraceptive method fails, and you are left at risk of falling pregnant."
