    ellaOne is a popular brand of morning after pill, licensed for use in the UK. It’s considered to be a highly effective form of emergency contraception when used correctly after unprotected sex. 

    It does this by altering the progesterone receptors in a woman’s body, which delays, or prevents, an egg from being released (ovulation). It is 95% effective at preventing pregnancy when taken within 5 days – or 120 hours – of having sex.

    This single dose treatment (30mg) contains the active ingredient ulipristal acetate. It can be taken with or without food, but must be swallowed whole with a glass of water. ellaOne can be taken at any point during your menstrual cycle.  

    We will ask you to complete a short online consultation before we process your order, to check that the morning after pill is suitable for you. You must tell your pharmacist, if you are taking any other medication – some drugs can prevent the ellaOne pill from working, and you may need to use another type of emergency contraception.

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

    Side effects

    As with all medication, there is a risk that you may suffer side effects after taking the ellaOne morning after pill. Common side effects include:

    • headache 
    • fatigue 
    • nausea and vomiting  
    • breast tenderness 
    • abdominal, back, and period pain 
    • pelvic pain and muscle aches 
    • mood changes 

    You may also experience dizziness, drowsiness, blurred vision, and/or loss of concentration. If this should happen, do not drive or operate machinery.

    If you vomit up to three hours after taking the ellaOne pill, then you will need to re-take it, or consider another form of emergency contraception, such as the IUD (‘coil’). 

    The morning after pill can interfere with some hormonal contraceptives, such as the pill. We recommend using a barrier form of contraception (e.g. condom) until the start of your next period. If you find that your period is more than seven days late, or you experience any symptoms of pregnancy, contact your GP for advice on what to do next.

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

    How does ellaOne work?

    ellaOne is a highly effective morning after pill that works by stopping the release of an egg from the ovaries (ovulation) so it cannot be embedded into the womb. 

    Can I use ellaOne every day?

    ellaOne is a type of emergency contraceptive pill and must not be used every day. For help choosing long-term methods of contraception, contact your GP or local sexual health clinic. You may also find the NHS guide to contraception a useful place to start.

    I think I might be pregnant, can I use ellaOne?

    If you think you might be pregnant then contact your GP for advice on what to do next. ellaOne will not work if you are pregnant – the morning after pill is a form of emergency contraception used to prevent pregnancy, it is not a method of abortion.

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

    Yes. If you vomit within three hours of taking the ellaOne pill, you will need to take it again or consider another form of emergency contraception, such as the IUD (‘coil’). 

    How will ellaOne affect my regular contraception?  

    ellaOne can interfere with regular hormonal contraception, such as the combined pill or patches. We recommend using a barrier form of contraception, like a condom or diaphragm, until the start of your next period.  

    Can I take ellaOne with other medications?

    Some drugs can interfere with ellaOne and stop it working effectively. 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 

    Will it prevent me from getting an STI?

    No, ellaOne cannot prevent you from getting a sexually transmitted disease (STI). Only condoms can protect you from getting HIV or any other type of STI.

    Can I take ellaOne while breastfeeding?

    You should not breastfeed in the week after taking the ellaOne morning after pill. Continue to use a breast pump to keep your milk flowing, but throw away the milk. The effect of ellaOne on breastfeeding is unknown.

    Where to get morning after pill?

    Your doctor can prescribe you ellaOne or you can buy it from an online pharmacy, like Post My Meds. Morning after pill prices start from £13.99.
