What's the lowdown?
The Cerelle pill should be taken at the same time every day
It’s important to understand your safe window, missed pill rules and when to seek help
If you have only missed one pill, there are rules to follow to help prevent pregnancy
The Cerelle pill is a brand of progestogen only pill. It is a popular choice due to its benefits and that it is generally safe for most women to take.
Cerelle works by preventing your body from releasing an egg each month, thickening the cervical mucus so sperm can’t enter the womb and by thinning out the womb lining to prevent a fertilised egg implanting and forming a pregnancy. If taken perfectly, Cerelle is 99% effective at preventing pregnancy.
Cerelle is designed to be taken every single day, which should in theory make it easier to remember. However, if you miss a Cerelle pill occasionally, you’re not alone and it’s not uncommon! It’s important for you to know exactly what to do if you have missed a pill, and The Lowdown is here to help make things easier.
Do you need to take Cerelle at the same time every day?
Ideally, the Cerelle pill should be taken at the same time every day. This makes sure it’s working effectively and can reduce side effects such as irregular spotting or bleeding.
If there is slight variation in the time you take it each day, you should still be protected against pregnancy. However, it’s important to understand your safe window and missed pill rules and when to seek help.
How late is considered a missed Cerelle pill?
The safe window in which to take the Cerelle pill is 12 hours. This means that you have 12 hours after the usual time you take your pill to remember it. If you are over 12 hours late to take your pill, this is a missed pill.

What happens if you miss one Cerelle pill?
Missing one day’s worth of Cerelle means that you need to follow specific instructions to avoid an accidental pregnancy. The easiest way to work out what to do is by using our simple-to-follow missed pill calculator.
If you have missed one pill, take it as soon as you remember, even if this means taking 2 pills on the same day. Then take your next pill at your usual time.
For the 48 hours after taking the next pill, avoid having sex or use condoms to give Cerelle time to become effective again.
If you had unprotected sex (sex without a condom) after your missed pill OR within the 48 hours after restarting your pill, you should think about using emergency contraception such as the morning-after pill or the copper coil.
If you think you need emergency contraception, speak to your healthcare professional or order the morning-after pill online.
What happens if you miss two Cerelle pills?
If you have missed two Cerelle pills, only take one as soon as you remember. You don’t need to take 2 or 3 together! Then follow the missed pill calculator or the guidance as above.
Can you get pregnant if you forget a Cerelle pill?
If you forget to take a Cerelle pill, pregnancy is a possibility:
- IF you have sex without a condom more than 12 hours after your last pill was due to be taken
- OR in the 48 hours after you have remembered to start taking your pill again
If this applies to you, it’s really encouraged to look into emergency contraception either via speaking to your healthcare professional, local sexual health clinic or using the morning after pill.
How to remember to take your Cerelle pill
The easiest way to avoid the drama of worrying about missed Cerelle pills and emergency contraception is to have a really great way of remembering to take it every day. Some people use an alarm on their phone or watch, while others place their Cerelle pills next to something they use every day such as a toothbrush or make-up bag.
It’s best to find a method of remembering that is personal to you. After a while, hopefully taking your pill will become a habit and you’ll remember without even thinking!
