    ellaOne is a contraceptive which is intended to prevent pregnancy after unprotected sex or if your contraceptive method has failed. This includes unprotected sex, if a condom tore or if you did not take your contraceptive pill as directed.

    ellaOne contains the substance ulipristal acetate which acts by modifying the activity of the natural hormone progesterone which is necessary for ovulation to occur. As a result, this medicine works by postponing ovulation.

    If you are worried about unwanted pregnancies occurring then ellaOne can be an effective drug when taken in a post-unprotected sex capacity.

    ellaOne is an over-the-counter medication, meaning that you can easily buy it online without the need for a prescription. Always follow the medical advice and read the patient information leaflet provided in the medication packet.

    Take one tablet orally as soon as possible and no later than 5 days (120 hours) after unprotected sex or contraceptive failure. This can be taken at any point during your menstrual cycle and at any time of day.

    ellaOne is not intended to be used as a form of regular contraception, but a solution for times when other methods have failed. If you have unprotected sex after taking the tablet, it will not stop you from becoming pregnant, and you should look into other contraception methods.

    - ellaOne should remain in the original packing to avoid moisture
    - Keep the blister inside of the outer packet to prevent light effecting the tablet
    - Keep at temperatures below 25°C
    - Keep out of reach from children
    - Do not throw away normal household waste, contact a pharmacist to ask how to dispose of these safely
    - Do not use outside expiry date, expiry date refers to the last day of said month

    About Emergency Contraception

    Emergency contraception has several names and connotations, one of them being “morning after pill”. This is a single dose pill taken to prevent pregnancy provided it is taken within the recommended timeframe.
    Emergency contraception such as Levonelle and ellaOne are contraceptives intended to prevent pregnancy after unprotected sex or if your contraceptive method has failed. For example:
    • if you had sex without protection;
    • if your or your partner’s condom tore, slipped or came off, or if you forgot to use one;
    • if you did not take your contraceptive pill as recommended.

    How long after intercourse can you take emergency contraception?

    Emergency contraception is used to prevent the conception of a baby, after unprotected sex has occurred.

    It’s good to highlight that the morning after pill is not used to abort a baby, but instead to prevent the woman from having an unwanted pregnancy. This is done by preventing the women from releasing an egg, which ultimately stops conception from occurring. Depending on the type of morning after pill used it could be up to 72 hours or 120 hours after having unprotected sex.

    More facts about ellaOne

    There are various facts about ellaOne that the NHS have listed online such as the fact that you need to take the emergency contraceptive pill within 5 days of unprotected sex for it to be effective, the sooner it’s taken the more effective it will be. If you’re sick within 3 hours of taking ellaOne then you will need to get another dose from your GP, pharmacist or GUM clinic. Another fact about ellaOne is that there are no serious side effects of using ‘the morning after pill’. Some people experience side effects, such as stomach pain or a heavier period but no life-threatening side effects. Some methods of contraception that will be protective for longer include the IUD, IUS, contraceptive implant and contraceptive injection. You will need to visit your GP, nurse or nearest sexual clinic to discuss the best options for you.
