Patient Information Leaflet
Nacrez 75 micrograms film-coated tablets EFG
Desogestrel
Read this leaflet carefully before you start taking this medicine.
Contents of the pack
Nacrez is used to prevent pregnancy. It contains a small amount of a type of female sex hormone, the progestogen desogestrel. For this reason, Nacrez is called a progestogen-only pill (POP), also known as a minipill. Unlike combined oral contraceptives, the minipill does not contain an estrogen in addition to the progestogen.
Most minipills work mainly by preventing sperm from entering the uterus. They do not always prevent the release of an egg from the ovary, which is the main effect of combined oral contraceptives. Nacrez differs from other minipills because it contains a dose that is high enough to prevent the release of an egg in most cases. Therefore, Nacrez has a high contraceptive effect.
Unlike combined oral contraceptives, Nacrez can be used by women who do not tolerate estrogens and by women who are breastfeeding. A disadvantage is that during the use of Nacrez, vaginal bleeding may occur at irregular intervals. It may also happen that menstruation is interrupted.
Nacrez, like other hormonal contraceptives, does not protect against HIV infection (AIDS) or any other sexually transmitted disease.
Do not take Nacrez
Consult your doctor before starting to take Nacrez if you are in any of these situations. Your doctor may advise you to use a non-hormonal contraceptive method. Consult your doctor immediately if any of these disorders occur for the first time while taking Nacrez.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Nacrez:
Tell your doctor if you are in any of these situations.
When using Nacrez in any of these situations, you may need to be kept under close observation. Your doctor can explain what you need to do.
Regular check-ups
While taking Nacrez, your doctor will ask you to come back for regular check-ups. In general, the frequency and type of these check-ups will depend on your individual situation.
Contact your doctor as soon as possible
Regularly check your breasts and contact your doctor as soon as possible if you detect any type of lump.
It has been shown that breast cancer is slightly more common in women who take oral contraceptives compared to women of the same age who do not take them. When women stop taking oral contraceptives, the risk decreases gradually. Ten years after stopping treatment, the risk is the same as in women who never took oral contraceptives. The development of breast cancer is rare in women under 40 years old, but the risk increases with age. Therefore, a higher number of breast cancer cases are diagnosed the older the woman is when she stops taking oral contraceptives. The duration of treatment with oral contraceptives is less important.
Out of 10,000 women who take oral contraceptives for up to 5 years but stop treatment around the age of 20, less than 1 additional case of breast cancer will be detected up to 10 years after stopping treatment, in addition to the 4 cases that are normally diagnosed in this age group. Similarly, out of 10,000 women who take oral contraceptives for up to 5 years but stop treatment around the age of 30, 5 additional cases of breast cancer will be detected, in addition to the 44 cases that are normally diagnosed. Out of 10,000 women who take oral contraceptives for up to 5 years but stop treatment around the age of 40, 20 additional cases of breast cancer will be detected, in addition to the 160 cases that are normally diagnosed.
It is considered that the risk of developing breast cancer in women who take progestogen-only contraceptives like Nacrez is similar to that of women who do not take oral contraceptives that also contain estrogen (combined oral contraceptives), although the evidence is less conclusive.
It appears to be less likely that breast cancers detected in women who take oral contraceptives will spread, compared to breast cancers detected in women who do not take them. It is not known whether the difference in breast cancer risk is due to the use of oral contraceptives. It is possible that more frequent examinations have been carried out, so that breast cancer may have been detected earlier.
Contact your doctor immediately if you detect any possible signs of a blood clot. For more information on signs, see "Contact your doctor as soon as possible", first bullet point.
A blood clot is the formation of a clot that can block a blood vessel. In some cases, a blood clot occurs in the deep veins of the legs (deep vein thrombosis). If the clot breaks loose from the veins where it formed, it can travel to the arteries of the lungs and block them. This causes a so-called "pulmonary embolism". As a result, life-threatening situations can occur; that is, they can lead to death. Deep vein thrombosis is not common. It can develop both when you are taking oral contraceptives and when you are not. It can also develop if you become pregnant.
The risk is higher in users of the pill than in non-users. It is believed that the risk with progestogen-only pills like Nacrez is lower than with pills that also contain estrogen (combined pills).
Children and adolescents
There are no data available on the safety and efficacy of desogestrel in adolescents under 18 years of age.
Psychiatric disorders
Some women who use hormonal contraceptives like Nacrez have reported depression or a depressed mood. Depression can be severe and sometimes can lead to suicidal thoughts. If you experience mood changes and symptoms of depression, contact your doctor for further medical advice as soon as possible.
Using Nacrez with other medicines
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines or herbal products. Also, inform any other doctor or dentist who prescribes you another medicine (or pharmacist) that you are using Nacrez. They can tell you if you need to take extra contraceptive precautions (e.g. condoms) and, if so, for how long.
Some medicines
These medicines include those used to treat:
If you are taking medicines or herbal products that may make Nacrez less effective, you should also use a barrier contraceptive method. Since the effect of another medicine on Nacrez can last up to 28 days after stopping the medicine, you need to use the additional barrier method for that time. Your doctor can tell you if you need to take extra contraceptive precautions and, if so, for how long.
Nacrez may also interfere with the action of other medicines, resulting in an increased effect (e.g. medicines containing ciclosporin) or a decreased effect (e.g. lamotrigine).
Consult your doctor or pharmacist before taking any other medicine.
Using Nacrez with food and drink
You can take Nacrez with or without food and drink.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Do notuse Nacrez if you are pregnant or think you may be pregnant.
Nacrez can be used during breastfeeding. Nacrez does not appear to affect milk production or the quality of breast milk. However, it has been reported that milk production may decrease during the use of Nacrez. A small amount of the active substance of Nacrez passes into breast milk.
The health of children who were breastfed for 7 months by mothers using Nacrez has been studied up to the age of 2.5 years. No effects on the growth and development of the children were observed.
If you are breastfeeding and want to use Nacrez, contact your doctor.
Driving and using machines
Nacrez does not affect your ability to drive or use machines.
Nacrez contains lactose
Nacrez contains lactose. If your doctor has told you that you have an intolerance to some sugars, contact them before taking this medicine.
Follow exactly the administration instructions of this medication indicated by your doctor and contained in this prospectus. In case of doubt, consult your doctor or pharmacist again.
Method of administration
The front of the package has arrows printed between the tablets. If you turn the package over and look at the back, you will see the days of the week printed on the aluminum foil. Each day corresponds to a tablet. Every time you start a new package of Nacrez, take a tablet from the top row. Do not start with any tablet. For example, if you start on a Wednesday, you must take the tablet from the top row marked (on the back) with "Wed". Keep taking one tablet a day until the package is empty. Always follow the direction indicated by the arrows. By looking at the back of the package, you can easily check if you have already taken the tablet for a specific day.
Take your daily tablet approximately at the same time. Take the whole tablet with water. It is possible that some bleeding may occur during the use of Nacrez, but you must continue taking the tablets in the usual way. When you finish a package of Nacrez, you must start a new one the next day; in this way, without interruption and without waiting for bleeding to occur.
Starting the first package of Nacrez
If you have not used hormonal contraceptives in the last cycle
Wait for your menstruation to start. On the first day of menstruation, take the first Nacrez tablet. You do not need to take additional contraceptive measures. You can also start treatment between days 2-5 of the cycle, but in that case, you must ensure that you use an additional contraceptive method (a barrier method, for example, a condom) during the first 7 days of treatment with the tablets.
If you switch from a combined oral contraceptive, vaginal ring, or transdermal patch
You can start taking Nacrez one day after taking the last tablet of the current oral contraceptive package or the day the vaginal ring or patch is removed (this means that you will never be without protection, whether you take tablets, wear a ring, or patch). If the package of the contraceptive you are currently taking also contains inactive tablets, you can start taking Nacrez one day after taking the last active tablet (if you are not sure which one it is, consult your doctor or pharmacist). If you follow these instructions, you do not need to take additional contraceptive measures. At the latest, you can also start treatment one day after the moment you stop being protected by tablets, ring, or patches, or after taking the inactive tablets of the contraceptive you are currently using. If you follow these instructions, you must ensure that you use an additional contraceptive method (a barrier method, for example, a condom) during the first 7 days of treatment with the tablets.
If you switch from another progestin-only oral contraceptive (minipill) to Nacrez
You can interrupt treatment at any time and start taking Nacrez immediately. You do not need to take additional contraceptive measures.
If you switch from an injectable or implant or an intrauterine device (IUD) that releases progestin to Nacrez
Start using Nacrez when you are due for the next injection or the day the implant or IUD is removed. You do not need to take additional contraceptive measures.
After having a child
You can start Nacrez between 21 and 28 days after the birth of your baby.
If you start later, make sure to use an additional contraceptive method (barrier method, for example, a condom) until you have completed the first 7 days of taking the tablet. However, if you have already had sexual intercourse, you must rule out pregnancy before starting the use of Nacrez. You can find additional information for breastfeeding women in "Pregnancy and lactation" in section 2. Your doctor may also advise you.
After a spontaneous or induced abortion
Your doctor will advise you what to do.
If you take more Nacrez than you should
No serious harmful effects have been reported due to taking too many desogestrel tablets at once. The symptoms that may appear are nausea, vomiting, and in young girls, a slight vaginal bleeding. For more information, ask your doctor for advice.
If you forget to take Nacrez
If you have delayed less than 12 hoursin taking a tablet, Nacrez still maintains its reliability. Take the tablet you forgot to take as soon as you remember, and then take the next tablet at the usual time. If you have delayed more than 12 hoursin taking a tablet, it is possible that the reliability of Nacrez may decrease. The more tablets you forget to take consecutively, the higher the risk that the contraceptive efficacy will decrease. Take the last tablet you forgot to take as soon as you remember, and then take the next tablets at the usual time. This means that you may take two tablets in one day. Use an additional contraceptive method (such as condoms)during the 7 days following treatment with the tablets. If you forgot to take one or more tablets in the first week of treatment and had sexual intercourse in the week before you forgot to take the tablets, you may become pregnant. Ask your doctor for advice.
If you have gastrointestinal disorders (e.g., vomiting, severe diarrhea)
Follow the advice for forgotten tablets in the previous section. If you vomit within 3-4 hours after taking your Nacrez tablet or have severe diarrhea, it is possible that the active ingredient may not have been fully absorbed.
If you interrupt treatment with Nacrez
You can interrupt treatment with Nacrez at any time. From the day you interrupt treatment, you will no longer be protected against pregnancy.
If you have any other doubts about the use of this medication, ask your doctor or pharmacist.
Like all medications, this medication can cause side effects, although not all people experience them.
Severe adverse reactions associated with the use of Nacrez are described in the paragraphs "Breast cancer" and "Thrombosis" in section 2 "What you need to know before taking Nacrez". For more information, read this section and consult your doctor immediately when you consider it convenient.
During the use of Nacrez, vaginal bleeding may occur at irregular intervals. It may be just a slight spotting that does not require the use of pads, or more intense bleeding, which is similar to a light menstruation and requires the use of pads. It may also happen that menstruation is completely interrupted. Irregular bleeding is not a sign that the contraceptive protection of Nacrez has decreased. In general, you do not need to take any action. Simply continue taking Nacrez. However, if the bleeding is intense or prolonged, you should consult your doctor.
