How it works

The Progesterone only pill (POP) / mini pill (Cerelle) is a small tablet you swallow daily that (unlike the combined pill) only contains one hormone – progesterone. It prevents pregnancy by making the fluid in your cervix thicker (which makes it more difficult for sperm to enter the womb), and preventing the lining of your womb thickening enough for an embryo to grow in it. The progestogen only pills with desogestrel in them (so all of them except Micronor, Noriday and Norgeston) can also stop ovulation.

    Detailed information

    How to get started with Cerelle

    • Your doctor or nurse will do some tests to make sure that you can take the Cerelle pill. They check your medical history, make sure that you’re not pregnant and take your blood pressure.
    • Most women can start the mini pill at any time in their period cycle. However unless you start the Cerelle mini pill on the first day of your period, you won’t be protected from pregnancy straight away. Make sure you read the packet carefully and use condoms or other methods until you’re covered.
    • There are special instructions for starting the progesterone only pill if you have just had a baby, abortion or miscarriage.
    • There are normally 28 pills in a pack, and unlike the combined pill you don’t have a break between packs.
    • It’s really important you reliably take the progestogen pill at the same time every day (more important than with the combined pill). There are two different types of progestogen only pill:
      • Three hour traditional progestogen-only pills must be taken within three hours of the same time every day
      • Twelve hour desogestrel progestogen-only pills must be taken within twelve hours of the same time every day.
    • If it helps, keep your pill packet somewhere you use or look at everyday (like your makeup bag) to remind you to take it, or set an alarm on your phone.
    • You will normally be given a prescription for the pill for a couple of months, and will need to go back to your doctor for regular check ups (e.g. blood pressure tests).

    Coming off the mini pill

    • Coming off the pill is easy – you just stop taking it. As soon as you stop taking it, you’re no longer protected from pregnancy.
    • If you have periods, you may prefer to wait until you reach the end of your current contraceptive pill packet before stopping, so you can keep your cycle more regular.
    • Check out our Cerelle reviews below to see how long it took most women’s cycles to return to their definition of ‘normal’, and read up about after effects they’ve experienced.

    Things that can wrong

    • Missing or forgetting to take a pill has happened to all of us. Check out the NHS guide on what to do, depending on how many you’ve missed and where you are in your cycle. If you’re in any doubt, make sure you use a condom or don’t have sex until you’re protected.
    • There are a few things that can stop the pill from working properly – make sure you watch out for these and check your pill information leaflet or speak to your doctor if you have any questions:
      • Vomiting and diarrhea will impact on how the pill is absorbed into your body. If you’re sick within two hours of taking the pill you’ll need to take another pill straight away and the next pill at the usual time. If you’re sick or have severe diarrhea for longer than this, check your pill packet for what to do next – and use condoms or abstain if you have any doubts.
      • Some medicines and antibiotics (like rifampicin and rifabutin, St John’s wort and anti-epilepsy drugs) change the way your body digests the pill.
    • With any combined type of hormonal contraception there is a slightly increased risk of developing blood clots in your veins and arteries.We are developing a full guide to the medical research on the serious and potentially life threatening side effects of contraceptives here.
