Commonly bought add-ons...

    Levonelle contains the active ingredient levonorgestrel, which is licensed for use in the UK as a form of emergency contraception. It is used to prevent pregnancy after unprotected sex, either because no protection was used, or a regular form of contraception failed, for example a torn condom or missed pill.

    It does this by stopping your ovaries from releasing an egg (ovulation), so it can’t be embedded into the womb. For Levonelle to work, you must take it within 72 hours of having unprotected sex, but we recommend taking it as soon as possible. 

    If you are already pregnant when you take Levonelle, it will not work – emergency contraception is not the same as an abortion. If you’ve missed a period, or you have any other symptoms of being pregnant, see your GP for advice on what to do next.

    The single dose treatment, Levonelle 1500, is also available to buy in its generic, unbranded form – levonorgestrel – for just £13.99. Both tablets work in the same way, and should be swallowed whole with a glass of water, no more than three days after unprotected sex.

    To check if you are suitable to take the morning after pill Levonelle, our team will ask you to complete a short online consultation. It’s important that you tell us if you are taking any other medication, as some drugs can prevent Levonelle from working effectively.

    We recommend reading the patient information leaflet before you start treatment.

    Levonelle pill: safe and effective emergency contraception

    Emergency contraception is there to try and help make sure you don’t suffer from an unwanted pregnancy after an unprotected sexual encounter. Levonelle is one of the most widely recognised examples of emergency contraception – otherwise known as the morning after pill. It contains levonorgestrel, which is a synthetic version of the natural hormone progesterone that is naturally produced by the ovaries.

    Taking Levonelle significantly reduces your risk of becoming pregnant after unprotected sex, and with PostMyMeds you can get the morning after pill delivered straight to your door for maximum accessibility when you need it.

    Avoid unwanted pregnancy

    Levonelle is an effective way to significantly reduce your risk of suffering an unwanted pregnancy after having unprotected sex. In order to get the highest level of effectiveness out of Levonelle, it should ideally be taken within 12 hours and no later than 72 hours of sexual activity, or 3 days. It does not necessarily interfere with your regular method of contraception.

    The morning after pill is a reactionary method of contraception, meaning that it only works to protect you from pregnancy from sexual activity that has already happened. It won’t continue to protect you against pregnancy, and any unprotected sex you have after taking the emergency pill can still result in pregnancy.

    Understanding Levonelle pill side effects

    The chances of experiencing serious side effects associated with taking the morning after pill are rare and are not usually considered long term. However, when you take a Levonelle pill, side effects may occur. These include headaches, stomach pain, changes to your next period, nausea and vomiting. Your next period may be early, late, or more painful than usual. None of these symptoms should last longer than a few days.

    You should seek out medical support if you think you might already be pregnant, or if your next period is more than seven days late. You should also see a doctor if your stomach pain is sudden and sharp.

    Taking the morning after pill

    The morning after pill can be taken by most women. It is often used by women who can’t use hormonal contraception such as the combined pill. Girls under the age of 16 can also take the emergency pill.

    However, you may not be able to take it if you are allergic to any of the ingredients, or if you take certain other medications. These include omeprazole, rifampicin, rifabutin, St John’s Wort and some medicines used to treat HIV, TB and epilepsy.

    The science behind a Levonelle pill

    The synthetic hormone levonorgestrel mimics the hormone progesterone which is produced by the ovaries. By doing so, the morning after pill effectively stops or delays the release of an egg, otherwise known as ovulation.

    The sooner after unprotected sex that you take Levonelle, the more likely it is to successfully prevent the onset of an unwanted pregnancy. While it isn’t intended to be used as a regular form of contraception, it can be used more than once in a single menstrual cycle if necessary.

    Side effects

    Women taking the Levonelle pill (or the unbranded version, levonorgestrel), may experience some side effects. Those most commonly reported, include: 

    • headache 
    • fatigue 
    • nausea and vomiting 
    • abdominal pain and diarrhoea 
    • breast tenderness 
    • menstrual cycle irregularities 

    If you vomit within three hours of taking Levonelle, then you must take another dose, or contact your GP or sexual health clinic for an alternative emergency contraception.

    If you normally take the pill, then you should take your next normal dose in line with the recommendation in the patient information leaflet or consult your GP. We also recommend using a barrier form of protection, such as a condom or diaphragm, for up to seven days for the combined pill (except Qlaira) and two days for the progesterone-only pill (known as the ‘mini pill’).

    You’ll find a full list of side effects and cautions in the patient information leaflet.

    Can I use Levonelle as a regular contraceptive?

    Levonelle is designed for use in emergencies after unprotected sex, and should not be used regularly. For help choosing a long-term contraception, contact your GP or sexual health clinic – you may also find the NHS guide to contraception a useful place to start

    I think I might be pregnant, what should I do?

    If you were already pregnant when you had unprotected intercourse, then Levonelle will not work – the morning after pill is a form of emergency contraceptive pill used to prevent pregnancy, it is not a method of abortion. Speak to your GP for advice on what to do next. 

    I’ve been sick, do I need to take it again?

    Yes, if you vomit within three hours of taking Levonelle, then you must take another dose or consider an alternative form of emergency contraception such as the IUD coil.

    Can I take Levonelle with other medication?

    There are some drugs that can limit the effectiveness of Levonelle. Tell your pharmacist, if you have taken any of the following in the last four weeks.

    • Medicines used to treat epilepsy 
    • Medicines used to treat tuberculosis 
    • Treatment for HIV 
    • Medicines used to treat fungal infections 
    • Herbal remedies containing St John’s wort 

    Am I suitable to take the morning after pill?

    ‘Levonelle is not suitable for young women under 16 years of age to purchase from a pharmacy. We do not advise taking this type of morning after pill from our service if:

    • You have a disease of your small bowel (such as Crohn’s) 
    • You have severe liver problems
    • You have a history of ectopic pregnancy 
    • You have ever had salpingitis (inflammation of the fallopian tubes) 

    Your pharmacist will check to make sure that you are suitable to take Levonelle, before they prescribe it.

    Will Levonelle prevent me from getting an STI?

    No, emergency contraception cannot prevent you from getting a sexually transmitted disease (STI). For protection from HIV and other STIs, we recommend using a condom.

    Is it safe to buy Levonelle online?

    Yes, Levonelle and its unbranded form, levonorgestrel, are both approved by the UK’s regulatory body for medicines and healthcare products (MHRA). Post My Meds is a registered online pharmacy with the General Pharmaceutical Council.

    Is the packaging discreet?

    Yes, we use unbranded, generic packing for your privacy. 

    How does Levonelle work?

    Levonelle contains the active ingredient, levonorgestrel, which is a synthetic, hormone-like substance. It’s used to prevent pregnancy after unprotected sex, by: 

    • Stopping or delaying the release of an egg (ovulation) 
    • Preventing sperm from fertilising an egg that may already have been released 

    You must take it within three days (72 hours) of unprotected sex for it to work. The earlier you take it, the more effective it is. 

     Can you take Levonelle twice in one cycle?

    It is possible to use Levonelle twice in one menstrual cycle, but it is not intended to be relied upon long-term. If you find yourself needing to use emergency contraception more than once, ask your GP for help finding a regular contraceptive that works for you. 

    Levonelle will not prevent you from getting pregnant if you have unprotected sex again after you’ve taken it, and it can’t protect you from sexually transmitted infections. 

    Does Levonelle delay your period?

    Taking Levonelle can alter your period – you might find it is early or late by a few days. 

    If it is more than seven days late, we recommend that you take a pregnancy test. You should generally wait at least three weeks after having unprotected sex before doing the test. 

    How often can you take Levonelle?

    Levonelle is not intended to be used as a regular method of contraception. It does not work as well as regular contraception and it should only be used in emergencies. Taking it more than once in any one menstrual cycle is more likely to disrupt your next period.  

    Does Levonelle work after 72 hours?  

    Levonelle will not prevent you from getting pregnant if it is taken more than 72 hours after you have had unprotected sex. The earlier you take it, the more effective it is. We recommend taking it as soon as possible, preferably within the first 12 hours.
