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 by women who are intolerant to estrogens and by breastfeeding women. The greatest inconvenience during the use of Cerazette may be irregular bleeding. Bleeding may also not occur at all.
The possibility of becoming pregnant while taking Cerazette (provided that no tablet has been missed) is very low.
Cerazette, like other hormonal contraceptives, does not protect against HIV infection (AIDS) and other sexually transmitted diseases.
Cerazette should not be used in the case of any of the following conditions. If any of these conditions occur, the doctor should be informed before starting Cerazette. The doctor may advise the use of a non-hormonal contraceptive method.
If any of the above symptoms occur for the first time while taking Cerazette, the doctor should be consulted immediately.
In the case of using Cerazette in any of the following cases, close medical supervision is required. Before starting Cerazette, the doctor should be informed about:
Decreased bone mass
Estrogens play an important role in maintaining normal bone mass. During the use of Cerazette, the concentration of natural estrogen - estradiol in the blood is comparable to its concentration in the first half of the natural cycle of a woman, but decreased compared to its concentration in the second half of the natural cycle. It is not known whether this has an effect on bone mass.
Breast cancer
Every woman is exposed to 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 decreases gradually and after 10 years of stopping oral contraceptives, it is the same for women who took oral contraceptives and those who never took them. Breast cancer occurs less frequently in women under 40, but the risk increases with the woman's age. Therefore, more cases of breast cancer occur in women taking oral contraceptives at an older age. The duration of oral contraceptive use is not that important.
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 was 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 were 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, after the age of 40, 20 more cases of breast cancer were 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 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 detection of breast cancer.
Venous thromboembolic disease
Venous thromboembolic disease is the formation of a blood clot 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 the place where it was formed, it can reach 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 oral contraceptives are not used. 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, the doctor should be contacted immediately (see "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, the doctor should be contacted as soon as possible for further medical advice.
There are no available clinical data on the efficacy and safety of Cerazette in adolescents under 18 years of age.
The doctor should be informed about the medicines or herbal products currently being taken or recently taken by the patient, as well as the medicines that the patient plans to take. The doctor of another specialty or the dentist prescribing other medicines (or pharmacist) should also be informed about the use of Cerazette. They may inform about the possible need to use additional contraceptive methods (e.g. condoms) and the time of their use, as well as whether it is necessary to modify the use of the prescribed medicine.
Some medicines
This applies to medicines used to treat:
If the patient is taking medicines or herbal products that may reduce the effectiveness of Cerazette, a mechanical contraceptive method should also be used. Due to the fact that 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. The doctor will inform the patient about the possible need to use additional contraceptive methods and the time of their use.
Cerazette may also interfere with the action of other medicines, which can increase (e.g. medicines containing cyclosporine) or decrease their action (e.g. lamotrigine).
Before taking any medicine, you should consult a doctor or pharmacist.
During the use of Cerazette, vaginal bleeding may occur irregularly. This can be slight spotting or intense bleeding. Bleeding may also not occur at all.
Irrregular bleeding does not mean that the contraceptive effectiveness of Cerazette is reduced. Usually, no action is required and Cerazette should be continued. However, if the bleeding is very heavy or prolonged, the doctor should be consulted.
During the use of all contraceptives containing small amounts of hormones, small fluid-filled blisters called functional ovarian cysts may develop in the ovaries. They usually resolve on their own. In some cases, they may cause slight abdominal pain. Rarely, they may require surgical intervention.
If the patient is pregnant or breastfeeding, suspects that she may be pregnant, or plans to have a child, she should consult a doctor or pharmacist before using this medicine.
Pregnancy
The use of Cerazette is contraindicated in pregnancy or if pregnancy is suspected.
Breastfeeding
Cerazette may be used during breastfeeding. It does not appear to affect milk production or quality. However, breast milk production has occasionally decreased during the use of 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.
In the case of breastfeeding and the desire to use Cerazette, the doctor should be consulted.
No effects of Cerazette on the ability to drive and use machines have been observed.
Cerazette contains lactose monohydrate. If the patient has previously been diagnosed with intolerance to some sugars, the patient should consult a doctor before taking the medicine.
This medicine should always be taken as directed by the doctor. In case of doubts, the doctor or pharmacist should be consulted.
The Cerazette blister 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 being taken. Each time a new package of Cerazette is started, the tablets should be taken from the top row of the blister, taking the tablets in the direction of the arrows, one per day, until the package is empty, e.g. if the tablets are started on Wednesday, the first tablet should be taken from the top row of the blister, marked with the abbreviation for Wednesday (see "Translation of the day of the week symbols on the packaging" at the end of the leaflet). This allows you to easily check if the tablet marked with a given day of the week has been taken on that day. The tablets should be taken at the same time every day. The tablet should be swallowed whole with water.
During the use of Cerazette, slight bleeding may occur. In this case, however, the tablets should be continued. After the tablets in the package are used up, a new package should be started the next day, without a break and without waiting for bleeding to occur.
Taking Cerazette tablets can be stopped at any time. Contraceptive effectiveness ends on the day of stopping the tablets.
The doctor should be contacted immediately in the following cases:
One should wait until the next menstrual period. The tablets should be started on the first day of the menstrual period. No additional contraceptive methods are needed.
The tablets can also be started between the 2nd and 5th day of the cycle, but in this case, an additional contraceptive method (mechanical) should be used for the first 7 days of taking the tablets in the first cycle.
Cerazette tablets can also be started no later than the first day after the break in taking the currently taken medicine, on the day of insertion of the next contraceptive vaginal ring or patch, or on the day after taking the last inactive tablet of the currently taken medicine. In these cases, an additional contraceptive method (mechanical) should be used for the first 7 days of taking Cerazette tablets.
No serious, harmful effects have been observed after taking more than one Cerazette tablet at a time. Nausea, vomiting, and slight vaginal bleeding may occur in both women and young girls. The doctor should be consulted.
If the delay in taking the tablets is less than 12 hours, the effectiveness of the tablet is maintained. The missed tablet should be taken as soon as possible, and the remaining tablets should be taken as usual.
If the delay in taking the tablets 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. The missed tablet should be taken as soon as possible, and the remaining tablets should be taken as usual. For the next 7 days, an additional contraceptive method (e.g. a condom) should be used. There is a possibility of becoming pregnant if one or more tablets are missed in the first week of starting Cerazette, if there was sexual intercourse in the week preceding the missed tablet. The doctor should be consulted.
One should proceed as in the case of a missed tablet (see above). If vomiting or severe diarrhea occur within 3 to 4 hours after taking a Cerazette tablet, the absorption of the active substance may have been reduced. In the case of severe diarrhea, the doctor should be consulted.
The use of Cerazette can be stopped at any time. If pregnancy is not planned, the doctor should be asked about another contraceptive method.
In the case of planning a pregnancy, it is usually recommended to wait until the 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.
The patient should inform the doctor about any unwanted changes in their health, especially if they are severe and prolonged, and about changes in their health that seem to be caused by taking Cerazette tablets.
Serious side effects related to the use of Cerazette are described in the "Breast cancer" and "Venous thromboembolic disease" sections in point 2 "Important information before taking Cerazette". The patient should read this section to obtain additional information and, if necessary, consult a doctor immediately.
If allergic reactions occur (hypersensitivity), including swelling of the face, lips, tongue, and/or throat causing difficulty breathing or swallowing (angioedema and/or anaphylactic reaction), the doctor should be contacted immediately.
During the use of Cerazette, vaginal bleeding may occur irregularly. This can be slight spotting or more intense bleeding, which looks more like a scarce menstrual bleeding, when it is necessary to use sanitary pads. Bleeding may also not occur at all.
Irrregular bleeding does not mean that the contraceptive effectiveness of Cerazette is reduced. Usually, no action is required, and Cerazette should be continued. However, if the bleeding is very heavy or prolonged, the doctor should be consulted.
Women taking Cerazette have reported the following side effects:
Uncommon: may occur in no more than 1 in 100 women
