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 biggest inconvenience when using Cerazette may be irregular bleeding. Bleeding may also not occur at all.
The possibility of becoming pregnant while using 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.
Do not use Cerazette if you have any of the conditions listed below. If any of these conditions occur, you should inform your doctor before starting to use Cerazette. The doctor may advise the use of a non-hormonal contraceptive method.
If any of the above conditions occur for the first time while using Cerazette, you should consult your doctor immediately.
When using Cerazette in any of the following situations, close medical supervision is required. Before starting to use Cerazette, you should inform your doctor about:
Decreased bone mass
Estrogens play an important role in maintaining normal bone mass. During the use of Cerazette, the level of natural estrogen - estradiol in the blood is comparable to its level in the first half of the natural cycle of a woman, but decreased compared to its level 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 the risk of breast cancer, regardless of whether she uses oral contraceptives or not. In women using oral contraceptives, breast cancer occurs slightly more often than in women of the same age who do not use them. After stopping oral contraceptives, the risk gradually decreases to be the same as for women who have never used oral contraceptives after 10 years of stopping oral contraceptives. Breast cancer occurs less frequently in women under 40, but the risk increases with the age of the woman. Therefore, more cases of breast cancer occur in women using oral contraceptives at an older age. The duration of oral contraceptive use is not that important.
Out of every 10,000 women using 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 using 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 using oral contraceptives for up to 5 years, over 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 using progestogen-only pills, such as Cerazette, is similar to the risk of breast cancer in women using combined pills, but the evidence is not final.
Cases of breast cancer diagnosed in patients using oral contraceptives seem to be less advanced than those found in women who do not use them. It is not known whether this difference is related to the use of oral contraceptives. It may be related to more frequent monitoring of patients using contraception 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 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 users of oral contraceptives than in non-users.
It is assumed that the risk of venous thromboembolic disease in users of oral contraceptives containing only progestogen, such as Cerazette, is lower than in users of oral contraceptives containing estrogen in their composition (combined pills). If symptoms of venous thromboembolic disease occur, you should contact your doctor immediately (see "Regular check-ups").
Psychiatric disorders
Some women using 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 to receive further medical advice.
There are no available clinical data on the efficacy and safety of Cerazette in adolescents under 18 years of age.
You should inform your doctor about the medicines or herbal products you are currently using or have recently used, as well as the medicines you plan to use. You should also inform your doctor of another specialty or dentist prescribing other medicines (or pharmacist) about the use of Cerazette. They may inform you 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:
If you are taking medicines or herbal products that may reduce the effectiveness of Cerazette, you should also use a mechanical contraceptive. 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. Your doctor will inform you 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, resulting in increased (e.g. medicines containing cyclosporine) or decreased activity (e.g. lamotrigine).
Before taking any medicine, you should consult your 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 you should continue to take Cerazette. You should contact your doctor if the bleeding is very heavy and prolonged.
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 disappear on their own. In some cases, they may cause slight abdominal pain. Rarely, they may require surgical intervention.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult your doctor or pharmacist before using this medicine.
Pregnancy
Using Cerazette is contraindicated in pregnancy or if pregnancy is suspected.
Breastfeeding
Cerazette can 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.
If you are breastfeeding and want to use Cerazette, you should consult your doctor.
It has not been found that Cerazette affects the ability to drive and use machines.
Cerazette contains lactose monohydrate. If you have been diagnosed with intolerance to some sugars, you should consult your doctor before taking the medicine.
This medicine should always be used as directed by your doctor. If you are unsure, you should consult your doctor or pharmacist.
The packaging 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 (see "Translation of day symbols on the packaging" in section 6 at the end of the leaflet), and on the other side, there are arrows showing the direction of the tablets to be taken. Each time you start taking tablets from a new packaging of Cerazette, you should start with the top row of the blister, taking the tablets in the direction of the arrows, one per day, until the packaging is empty, e.g. if you start taking the tablets on Wednesday, you should take the first tablet from the top row marked with the inscription WED. 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, you should continue to take the tablets. After the tablets in the packaging are used up, you should start taking the tablets from a new packaging 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.
A woman using 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 can also start taking Cerazette on the first day after the break in taking your current contraceptive, on the day of insertion of the next vaginal ring or patch, or on the day after taking the last placebo 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. You should consult your doctor.
If the delay in taking a tablet is less than 12 hours, the effectiveness of the tablet is maintained. You should take the missed tablet as soon as possible, and take the remaining tablets as usual.
If the delay in taking a 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. You should take the missed tablet as soon as possible, and take the remaining tablets as usual. For the next 7 days, you should use an additional contraceptive method (e.g. a condom). There is a possibility of becoming pregnant if you miss one or more tablets in the first week of starting to take the tablets, if you had sexual intercourse in the week before missing the tablet. You should consult your doctor.
You 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, you should consult your doctor.
You can stop taking Cerazette at any time. If you do not plan to become pregnant, you should ask your doctor for another contraceptive method.
In the case of planned 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.
You should inform your doctor about any unwanted changes in your health, especially if they are severe and prolonged, and about changes in your health that seem to be caused by taking Cerazette tablets.
Severe 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 using Cerazette". You should read this section to obtain additional information and, if necessary, consult your 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), you should contact your doctor immediately.
During the use of Cerazette, vaginal bleeding may occur irregularly. This can be slight spotting that does not require the use of sanitary pads or more intense bleeding that looks like a scanty menstrual period, when sanitary pads are needed. 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 you can continue to take Cerazette. However, if the bleeding is very heavy or prolonged, you should contact your doctor.
Women using Cerazette have reported the following side effects:
Common: may occur in up to 1 in 10 women
Uncommon: may occur in up to 1 in 100 women
Rare: may occur in up to 1 in 1000 women
