How to take Cerazette
Take one pill every day, at the same time each day, with no breaks to prevent pregnancy. You take the packs back-to-back without a break, including during your period. Many women won’t have their period at all while on Cerazette – this is normal and should not cause concern.
How does Cerazette work?
Cerazette is a progestogen-only-pill (POP) that works in two ways. It prevents pregnancy by thickening the mucus in the cervix. This prevents sperm from entering the womb and fertilising an egg. Cerazette also stops ovulation by prevents egg cells from ripening. This makes it a highly effective pill.
How effective is Cerazette?
If you start using Cerazette on days 1-5 of your period, you will be immediately protected against pregnancy.
Used correctly, Cerazette can be up to 99% effective in preventing pregnancy. However, if you are vomiting or have severe diarrhoea you may not be protected against pregnancy. If this happens, continue to take the pill as usual but use a condom whilst you're ill. If this continues for more than 24 hours you should follow the same steps as a missed pill.
Are Cerazette and Cerelle the same thing?
Cerazette, Cerelle and Desogestrel all contain the same active ingredient and they work in exactly the same way to protect you against pregnancy.
What are the side effects of Cerazette?
Most women will not experience any side effects on Cerazette. Some women experience irregular bleeding. This side effect is common and usually settles within three months.
You may experience spotting or heavier bleeding with which you need to use tampons or pads. You don’t need to do anything to stop the bleeding, however if bleeding is heavy or prolonged speak to your doctor.
Other side effects can include headaches, acne, feeling sick, mood swings, and breast sensitivity.

What happens if you forget to take the pill
If you forget to take it, unlike most mini pills, Cerazette offers a window of 12hrs in which it can be taken and still protect you from pregnancy. Take the forgotten pill as soon as you remember. Then take the next pill at the normal time. This may mean taking two pills in one day.
If you do not take it within 12hrs of the usual time, you will not be protected against pregnancy. Continue to take your pills as usual but use condoms for the next two days. If you've had unprotected sex during this time, you may need emergency contraception.
