Desogestrel
Cerazette is used to prevent pregnancy. The tablets contain a small amount of the female sex hormone, progestogen, called desogestrel. For this reason, Cerazette is called a progestogen-only pill. Unlike combined oral contraceptives, progestogen-only pills do not contain estrogen, the other female sex hormone.
The mechanism of action of most progestogen-only pills is mainly based on preventing sperm migration through the cervix. Unlike combined oral contraceptives, they do not always inhibit ovulation. Cerazette differs from other progestogen-only pills in that, like combined pills, it usually inhibits ovulation. As a result, Cerazette is a very effective contraceptive.
Unlike combined products, it can be used in women who are intolerant to estrogens and in breastfeeding women. The biggest inconvenience when using Cerazette may be irregular bleeding. Bleeding can also not occur at all.
The possibility of becoming pregnant while taking Cerazette (provided that no tablet is missed) is very low.
Cerazette, like other hormonal contraceptives, does not protect against HIV (AIDS) and other sexually transmitted diseases.
Do not take Cerazette if you have any of the conditions listed below. If any of these conditions occur, tell your doctor before starting Cerazette. Your doctor may advise you to use a non-hormonal method of contraception.
If any of the above conditions occur for the first time while taking Cerazette, you should immediately consult your doctor.
When taking Cerazette in any of the following situations, close medical supervision is required. Before starting Cerazette, tell your doctor if you have:
Possible serious diseases
Reduced bone mass
Estrogens play an important role in maintaining normal bone mass. During treatment with Cerazette, the level of natural estrogen - estradiol in the blood is comparable to its level in the first half of the natural female cycle, but reduced compared to its level in the second half of the natural female cycle. It is not known whether this has an effect on bone mass.
Breast cancer
Every woman is exposed to the risk of breast cancer, regardless of whether she is taking oral contraceptives or not. In women taking oral contraceptives, breast cancer occurs slightly more often than in women of the same age who do not take them. After stopping oral contraceptives, the risk gradually decreases to become the same as for women who have never taken oral contraceptives after 10 years of stopping oral contraceptives. Breast cancer occurs less frequently in women under 40 years of age, but the risk increases with the age of the woman. Therefore, more cases of breast cancer occur in women taking oral contraceptives at an older age. The duration of oral contraceptive use does not have such great significance.
Out of every 10,000 women taking oral contraceptives for no more than 5 years, up to the age of 20, fewer than 1 additional case of breast cancer is diagnosed within 10 years of stopping oral contraceptives, compared to 4 cases of breast cancer usually diagnosed in this age group. Similarly, out of every 10,000 women taking oral contraceptives for up to 5 years, up to the age of 30, 5 additional cases of breast cancer are diagnosed, compared to 44 cases usually diagnosed in this age group. Out of every 10,000 women taking oral contraceptives for up to 5 years, over the age of 40, 20 more cases of breast cancer are diagnosed, compared to 160 cases usually diagnosed.
The risk of breast cancer in women taking progestogen-only pills, such as Cerazette, is similar to the risk of breast cancer in women taking combined pills, but the evidence is not yet final.
Cases of breast cancer diagnosed in patients taking oral contraceptives seem to be less advanced than those found in women who do not take them. It is not known whether this difference is related to the use of oral contraceptives. It may be related to more frequent medical check-ups and thus earlier diagnosis of breast cancer.
Venous thromboembolic disease
Venous thromboembolic disease is a condition where a blood clot forms that can block a blood vessel. Sometimes it can occur in the deep veins of the legs (deep vein thrombosis). If the clot breaks loose from where it formed, it can travel to the lungs and block a pulmonary artery, forming a pulmonary embolism. This can lead to death. Deep vein thrombosis is very rare. It can also develop if you are not taking oral contraceptives. It can also occur during pregnancy. The risk of venous thromboembolic disease is higher in women taking oral contraceptives than in those not taking them.
It is assumed that the risk of venous thromboembolic disease in women taking oral contraceptives containing only progestogen, such as Cerazette, is lower than in women taking oral contraceptives that also contain estrogen in their composition (combined pills). If symptoms of venous thromboembolic disease occur, you should immediately contact your doctor (see section "Regular check-ups").
Psychiatric disorders
Some women taking hormonal contraceptives, including Cerazette, have reported depression or low mood. Depression can be severe and sometimes lead to suicidal thoughts. If mood changes and symptoms of depression occur, you should contact your doctor as soon as possible for further medical advice.
There are no clinical data available on the efficacy and safety of Cerazette in adolescents under 18 years of age.
Tell your doctor about any medicines or herbal products you are currently taking, or have recently taken, and about any medicines you plan to take. Also, tell any other doctor or dentist prescribing other medicines (or pharmacist) that you are taking Cerazette. They may tell you if you need to use additional contraceptive methods (e.g. condoms) and for how long, and whether you need to adjust the dose of the prescribed medicine.
Some medicines:
If you are taking medicines or herbal products that may reduce the effectiveness of Cerazette, you should also use a mechanical contraceptive method. Since the effect of another medicine on Cerazette may persist for up to 28 days after stopping the medicine, it is necessary to use additional mechanical contraception during this time. Your doctor will inform you about the possible need to use additional contraceptive methods and the duration of their use.
Cerazette may also affect the action of other medicines, resulting in increased (e.g. medicines containing cyclosporin) or decreased activity (e.g. lamotrigine).
Before taking any medicine, consult your doctor or pharmacist.
During treatment with Cerazette, vaginal bleeding may occur irregularly. This can be slight spotting or heavy bleeding. Bleeding may also not occur.
Irrregular bleeding does not mean that the contraceptive effectiveness of Cerazette is reduced. Usually, no action is required and you should continue taking Cerazette. However, if the bleeding is very heavy or prolonged, you should contact your doctor.
During treatment with all hormonal contraceptives that contain small amounts of hormones, small fluid-filled blisters called functional ovarian cysts may develop in the ovaries. They usually disappear on their own. In some cases, they may cause mild abdominal pain. Rarely, they may require surgical intervention.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Do not take Cerazette if you are pregnant or think you may be pregnant.
Breastfeeding
Cerazette can be used during breastfeeding. It does not appear to affect milk production or quality. However, a decrease in milk production has been reported in some cases during treatment with Cerazette. Small amounts of the active substance of Cerazette pass into breast milk.
There are observations of the health of children up to 2.5 years of age whose mothers used Cerazette for 7 months. No effect on the growth and development of the child has been observed.
If you are breastfeeding and wish to use Cerazette, consult your doctor.
No effects of Cerazette on the ability to drive or use machines have been observed.
Cerazette contains lactose. If you have been diagnosed with an intolerance to some sugars, you should consult your doctor before taking Cerazette.
A woman taking Cerazette should be informed by her doctor about the need for regular check-ups. Usually, the frequency and type of check-ups depend on the individual characteristics of the woman.
You should contact your doctor immediately in the following situations:
Always take this medicine exactly as your doctor has told you. If you are not sure, ask your doctor or pharmacist.
The pack of Cerazette contains 28 tablets. On one side of the blister, each tablet has a symbol of the day of the week on which it should be taken, and on the other side, there are arrows indicating the direction of the tablets to be taken. Each time you start a new pack of Cerazette, take the tablet from the top row of the blister, taking the tablets in the direction of the arrows, one each day, until the pack is empty, e.g. if you start taking the tablets on a Wednesday, take the first tablet from the top row marked with the day "Wednesday". This will help you check that you have taken a tablet on the corresponding day of the week. Take the tablets at the same time every day. Swallow the tablet whole with water. During treatment with Cerazette, spotting may occur. In this case, continue taking the tablets. After finishing the tablets in the pack, start taking the tablets from a new pack the next day, without interruption and without waiting for bleeding to occur. You can stop taking Cerazette at any time. Contraceptive effectiveness ends on the day you stop taking the tablets.
You can also start taking the tablets between days 2 and 5 of your cycle, but in this case, you should use an additional contraceptive method (mechanical contraceptive methods) for the first 7 days of taking the tablets in the first cycle.
You can also start taking Cerazette no later than the first day after the break in taking your current contraceptive, the day you insert a new vaginal ring or apply a new patch, or the day after you take the last inactive tablet of your current contraceptive. In these cases, you should use an additional contraceptive method (mechanical) for the first 7 days of taking Cerazette tablets.
No serious harmful effects have been observed after taking more than one Cerazette tablet at the same time. Nausea, vomiting, and slight vaginal bleeding may occur in both women and young girls. Consult your doctor.
If the delay in taking the tablet is less than 12 hours, the effectiveness of the tablet is maintained. Take the missed tablet as soon as possible, and continue taking the rest of the tablets as usual.
If the delay in taking the tablet is more than 12 hours, the effectiveness of the tablet may be reduced. The more missed tablets, the higher the risk of reduced contraceptive effectiveness. Take the missed tablet as soon as possible, and continue taking the rest of the tablets as usual. For the next 7 days, use an additional contraceptive method (e.g. condoms). There is a possibility of becoming pregnant if you miss one or more tablets in the first week of taking the tablets, if you had sex in the week before missing the tablets. Consult your doctor.
Follow the same procedure as when you miss a tablet (see above). If vomiting or severe diarrhea occur within 3 to 4 hours of taking a Cerazette tablet, the absorption of the active substance may be reduced. In the case of severe diarrhea, you should contact your doctor.
You can stop taking Cerazette at any time. If you do not plan to become pregnant, ask your doctor for another contraceptive method.
If you plan to become pregnant, your doctor usually advises you to wait until your first natural menstrual period before becoming pregnant. This will make it easier to determine the expected date of delivery.
Like all medicines, Cerazette can cause side effects, although not everybody gets them.
Tell your doctor if you experience any unwanted changes in your health, especially if they are severe and prolonged, and about any changes in your health that you think may be due to taking Cerazette.

If you experience an allergic reaction (hypersensitivity), including swelling of the face, lips, tongue, and/or throat, causing difficulty breathing or swallowing (angioedema and/or anaphylactic reaction), you should immediately contact your doctor.
During treatment with Cerazette, vaginal bleeding may occur irregularly. This can be slight spotting or more heavy bleeding, which looks more like a scanty menstrual bleeding, when a pad is needed. Bleeding may also not occur.
Irrregular bleeding does not mean that the contraceptive effectiveness of Cerazette is reduced. Usually, no action is required, and you should continue taking Cerazette. However, if the bleeding is very heavy or prolonged, you should contact your doctor.
