Cerazette Mini Pill

Cerazette is a progestogen-only pill, also known as the mini pill.

Each Cerazette pill contains 75 micrograms desogestrel, a synthetic version of the hormone progesterone. It does not contain oestrogen, which makes Cerazette an ideal option if you get oestrogen-related side effects from contraceptives like the combined pill, which does contain oestrogen.

Important: Taking Cerazette does not protect you against sexually transmitted infections (STIs). You’ll need to use a condom to protect yourself against STIs.

Cerazette is for people who are at risk of unwanted pregnancies. A doctor or nurse can check to see if Cerazette is right for you.

Cerazette can be a good choice for people who:

• are over the age of 35 and who smoke
• have high blood pressure
• have had previous blood clots
• have suffered from migraines with aura
• have certain heart conditions
• are overweight

This is because these are all reasons why a doctor might not prescribe the combined pill to someone due to the oestrogen in them. Since Cerazette only contains progesterone, it’s safer for some people.

You should take 1 Cerazette pill at around the same time each day. Swallow it whole with water. Don’t chew, cut or crush it.

To make it easier to remember to take your pill, take Cerazette in the order shown on the back of each pack. Follow the days of the week in order. You could also use a pill reminder box if you’re worried about forgetting.

Once you finish your Cerazette strip, start a new one the next day without a pill-free break.

Cerazette works to prevent pregnancy in 2 ways:

• it stops ovulation, so there is no egg for the sperm to fertilise
• it prevents sperm from reaching the womb by thickening the mucus at the entrance to your womb

The progesterone in Cerazette works the same way your natural hormones would to help avoid pregnancy.

When Cerazette starts to work depends on whether or not you are already using hormonal contraception.

Taking the mini pill when you have not used hormonal contraception for the past month or longer:

Take your first Cerazette tablet on the first day of your period, or up to and including day 5 of your period. It will start to work immediately, and no additional contraception is required.

If you take the first tablet after day 5 of your period, Cerazette will not start to work immediately. You will need to use a barrier method of contraception, like condoms, for the first 2 days of taking Cerazette.

Changing to Cerazette from another mini pill:

Take your first Cerazette tablet any day you want to and it will start working immediately. You do not need to use additional contraception.

Changing to Cerazette from the combined pill, transdermal patch or vaginal ring:

If you normally have a break as part of your combined pill, transdermal patch or vaginal ring routine, and you start taking Cerazette when the break finishes, Cerazette will not work immediately. You will need to use a barrier method of contraception, like condoms, for the first 2 days. You can instead start Cerazette after your last active pill before your break – you will not need any additional precautions then.

If you do not normally have a break, you can start taking Cerazette immediately after taking the last active pill or removing your patch or ring. Cerazette will work immediately to protect you from pregnancy.

Changing to Cerazette from an implant, injection or IUD:

You can start using Cerazette when your next injection is due, or your implant or intrauterine device (IUD) is removed. Cerazette will work immediately to protect you from pregnancy.

You can start Cerazette at any point in your cycle. If you start during the first 5 days of your period, you will be protected from pregnancy straight away. If you start on any other day of your cycle, you need to take Cerazette for 2 days in a row before it starts to work. During these first 2 days, use extra protection like condoms if you have sex.

What you should do if you miss a pill depends on how late you remember to take it:

• If you miss a pill and are less than 12 hours late, take it as soon as you remember and take the next pill at your usual time.
• If you’re more than 12 hours late, take the next pill at your usual time. Use extra contraception, like condoms, for the next 2 days.

If you have unprotected sex and forget to take your pill for over 12 hours, speak to a doctor or pharmacist about getting emergency contraception.

What should I do if I'm too late to take a pill?

If you are too late to take your Cerazette pill, take it as soon as you remember and use additional barrier contraception for the next 2 days, like condoms. It takes 2 days for the progesterone in your Cerazette pill to thicken the mucus at the entrance to the womb.

The longer it is since you took your pill, the higher the risk of getting pregnant. If you have had unprotected sex, talk to a doctor or pharmacist about emergency contraception.

What should I do if I vomit after taking the pill?

If you vomit or have diarrhoea within 4 hours of taking your pill, take another pill as soon as possible within the 12-hour window and then take your pill as usual.

When you are sick or have diarrhoea soon after taking your pill, your system may not have absorbed it properly. If you keep being sick or having diarrhoea, keep using condoms until 2 days after your symptoms improve to stay protected.

You can stop taking Cerazette whenever you like. You will not be protected from pregnancy as soon as you stop taking it, though. Therefore it’s best to talk to a doctor before stopping Cerazette. They can give you advice about stopping and alternative types of contraceptive methods.

Yes, you can switch your contraceptive pill. You may need to use additional contraception depending on whether you are switching from another mini or a combined pill. Talk to your doctor and read the patient information leaflet for Cerazette to ensure you are protected from pregnancy while you switch pills.

You can buy Cerazette online from any registered online doctor service, like ZAVA. Make sure the service you are using is regulated and approved by the Quality Care Commission. Online doctor services allow doctors to approve treatments like Cerazette using online assessments, which means you don’t have to make a face-to-face appointment to order your contraceptive pill.

Taking Cerazette as recommended is 99% effective at preventing pregnancy.

However, in typical daily use, the mini pill is estimated to be 91% effective, as people forget to take it at the right time or are ill.

You may experience some side effects when you start taking Cerazette.

Cerazette contraceptive pills are suitable for most women to take. But, you should not take Cerazette if you have:

• any allergies to desogestrel, lactose or any other ingredients in Cerazette
• liver disease
• a high chance of thrombosis (blood clots)
• breast cancer
• unexplained vaginal bleeding

Can I take Cerazette while pregnant or breastfeeding?

No, you cannot take Cerazette if you are pregnant or think you might be pregnant.

It is safe to take Cerazette while you are breastfeeding. Small amounts of the pill can enter the breast milk, but studies have found that these do not impact the baby. Talk to your doctor if you want to take Cerazette while breastfeeding.

See our page on contraception after giving birth for more information.

Cerazette can interact with other medications and affect how well they work. Also, other medications can change Cerazette’s effectiveness.

Before you take Cerazette, you should let your doctor know if you’re on medications for:

• high blood pressure (hypertension)
• angina, such as diltiazem
• fungal infections
• tuberculosis
• hepatitis C or HIV
• epilepsy
• low mood, such as St John’s Wort

Taking these medications with your Cerazette pill might make it less effective.

Several contraceptive alternatives are available if you do not want to take Cerazette. You could also try another mini pill if you want an oestrogen-free pill option and Cerazette isn’t right for you.

Cerelle and Cerazette are 2 mini pills with exactly the same dosage and active ingredient – 75 micrograms of desogestrel. This means that they work in an almost identical way as medications. The effectiveness, side effects and benefits will be almost completely the same.

The main difference is the non-active ingredients used to make up the pills. These are different because Cerelle and Cerazette are produced by different manufacturers. Cerelle is made by Gedeon Richter and Cerazette is made by Organon Pharma Limited.

While Cerelle uses potato starch, polyvinyl alcohol and macrogol 3000, Cerazette uses maize starch, hypromellose and macrogol 400. Both contain lactose and are unsuitable for vegans and those with lactose intolerance.

Cerazette and Cerelle both contain the same active ingredient, desogestrel. So unfortunately, if you react badly to Cerazette then Cerelle might not be a good option, even though both have the biggest window of opportunity for taking them, 12 hours.

There are other types of mini pills available. Some, like Cerelle, are similar to Cerazette and have a 12-hour window in which you have to take them. Others have a 3-hour window in which you have to take them. These include Norgeston and Noriday.

Norgeston and Noriday contain levonorgestrel and norethisterone respectively, which are different progesterones to Cerazette and Cerelle. So, if you’ve tried Cerazette already and decided it wasn’t for you, you could try either of these.

The active ingredient in Cerazette is 75 micrograms of desogestrel, a synthetic version of the hormone progestogen.

Contraceptive pills in the UK normally have lactose in, which means they’re not suitable for people with lactose intolerance or vegans. Whether or not Cerazette is suitable for people of the muslim faith is not clear.

Online patient reviews from thelowdown.com show that Cerazette is rated 2.6 out of 5. Patient reviews can be a good way of understanding the experience of others on a medication but they may not always be a fair representation. The best way to find out how well a medication works for you is by trying it out. If you try Cerazette and you don’t get on with it, you can always switch to another contraceptive option if you need to.
