Kerizet is used to prevent pregnancy. Kerizet contains a small amount of a type of female sex hormone, the progestogen desogestrel.desogestrel. For this reason, Kerizet is known as a progestogen-only pill. Unlike combined pills, the mini-pill does not contain estrogen-type hormones along with the progestogen.
Most progestogen-only pills primarily work by preventing sperm from entering the uterus, but they do not always prevent the egg from maturing, which is the primary action of combined pills. Kerizet is different from most progestogen-only pills since it has a dose that is high enough in most cases to prevent the egg from maturing. Therefore, Kerizet provides high contraceptive efficacy.
Unlike the combined pill, Kerizet can be taken by women who do not tolerate estrogens and women who are breastfeeding. A disadvantage is that it could have irregular vaginal bleeding during the use of Kerizet. It could also not bleed.
Do not take Kerizet
Inform your doctor before using Kerizet if any of these circumstances affect you. Your doctor may recommend that you use a non-hormonal birth control method.
Consult your doctor immediately if any of these circumstances occur for the first time while using Kerizet.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Kerizet.
Inform your doctor before starting to use Kerizet if:
If you use Kerizet in any of the described situations, you must remain under medical supervision. Your doctor may explain what you should do.
Breast cancer
Have your breasts regularly examined and contact your doctor as soon as possible if you notice any lump in your breasts.
Breast cancer has been observed at a slightly higher frequency in women taking the pill than in women of the same age who are not taking it. If the woman stops taking the pill, the risk decreases gradually, so that 10 years after stopping the risk is the same as that of women who have never taken it. Breast cancer is rare before the age of 40, but the risk increases as the woman gets older. Therefore, the additional number of breast cancers diagnosed is greater the older the age at which the pill was stopped. The duration of use of the pill is not as important.
Of every 10,000 women who have taken the pill for up to 5 years and who stop taking it around the age of 20, there will be fewer than one additional case of breast cancer observed 10 years after stopping the pill, which will be added to the 4 cases normally diagnosed in this age group. Similarly, of 10,000 women who have taken the pill for up to 5 years and who stop taking it around the age of 30, there will be 5 additional cases, in addition to the 44 cases normally diagnosed. In 10,000 women who have taken the pill for up to 5 years and who stop taking it around the age of 40, there will be 20 additional cases, in addition to the 160 cases normally diagnosed.
It is believed that the risk of breast cancer in users of progestin-only pills like Kerizet is similar to that of women taking combined pills, although the data do not allow for clear conclusions.
It appears that the breast cancers found in women taking the pill are less extensive than the breast cancers found in women who are not taking it. The cause of the difference in breast cancer risk is unknown. It may be that women are more frequently monitored, so that breast cancer is detected earlier.
Thrombosis
Contact your doctor immediately if you notice possible signs of thrombosis (see also “Regular checks”).
Thrombosis is the formation of a blood clot that can block a blood vessel. Thrombosis sometimes occurs in the deep veins of the legs (deep vein thrombosis). If the clot breaks off from the veins where it formed, it can reach and block the arteries of the lungs, causing what is known as “pulmonary embolism.” This can lead to fatal situations. Deep vein thrombosis is rare. It can develop while taking or not taking the pill. It can also occur if you become pregnant.
The risk of thrombosis is higher in pill users than in non-users. It is believed that the risk in users of progestin-only pills like Kerizet is lower than in users of combined pills that contain estrogen.
Mental health disorders
Some women who use hormonal contraceptives, including Kerizet, have reported depression or depressed mood. Depression can be severe and sometimes leads to suicidal thoughts. If you experience mood changes and depressive symptoms, contact your doctor for medical advice as soon as possible.
Children and adolescents
There are no available clinical data on safety and efficacy in children and adolescents under 18 years of age.
Use of Kerizet with other medications
Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication or herbal remedies. Also inform any other doctor or dentist who prescribes another medication (or your pharmacist) that you are taking Kerizet. They can inform you if you need to use additional contraceptive measures (for example, the use of condoms) and if necessary, for how long, or if you need to modify the use of the other medication.
Some medications
These include medications used to treat:
If you are taking medications or herbal remedies that may make Kerizet less effective, you should also use a barrier contraceptive method. Since the effect of another medication on Kerizet can last up to 28 days after stopping the medication, you will need to use the additional barrier contraceptive method during that time. Your doctor can inform you if you need to take additional contraceptive measures and for how long.
Kerizet can also interfere with the effect of other medications, causing an increase in effect (for example, medications with cyclosporine) or a decrease in effect (for example, lamotrigine).
Consult your doctor or pharmacist before taking any medication.
Pregnancy, breastfeeding, and fertility
Pregnancy
Do not use Kerizet if you are pregnant or suspect you may be pregnant.
Breastfeeding
Kerizet can be used during breastfeeding. Kerizet does not appear to affect milk production or quality. However, occasionally, a decrease in milk production has been reported during the use of Kerizet. A small amount of the active ingredient of Kerizet passes into breast milk.
A study was conducted on the health of children in breastfeeding for 7 months, whose mothers used desogestrel, until the children were 2.5 years old. No effects were observed on the growth or development of the children.
If you are breastfeeding and want to use Kerizet, consult your doctor.
Driving and operating machines
There is no indication that the use of Kerizet produces any effect on alertness and concentration.
Kerizet contains lactose and soy oil
Kerizet contains lactose. If your doctor has told you that you have a certain sugar intolerance, consult with him before taking this medication.
If you are allergic to peanuts or soy, do not use this medication.
Regular checks

When and how to take Kerizet
Follow exactly the administration instructions of this medication indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.
The blister of Kerizet contains 28 tablets. There are arrows printed on the front face of the blister, between the tablets. If you turn the blister over and look at the back face, you will see the days of the week printed on the sheet. Each day corresponds to a tablet.
Each time you start a new blister of Kerizet, take a tablet from the top row, but not any tablet. For example, if you start on a Wednesday, you should take the tablet from the top row marked (from the back) “WED”. Continue taking one tablet a day until the blister is empty, always following the direction of the arrows. Looking at the back face of the blister, you can easily check if you have already taken your tablet on a given day.
Take your tablet each day approximately at the same hour.
Swallow it whole with water. Some bleeding may occur during the use of Kerizet, but you should continue taking the tablets normally. When you finish a blister, start a new one the next day, so without leaving any day of rest and without waiting for bleeding to appear.
Starting the first package of Kerizet
Wait for your period and on the first day of the period, take the first tablet of Kerizet.
This way, you do not need to take additional contraceptive precautions.
You can also start on days 2 to 5 of your cycle, but in this case, make sure to use an additional contraceptive method (barrier method, condom) during the first 7 days of treatment with the tablets.
You can start taking Kerizet the day after taking the last tablet of the current package or the day the vaginal ring or transdermal patch is removed (this means you do not have to leave a period of rest from the tablets, ring, or patch). If your current pill contains inactive tablets, you can start taking Kerizet the day after taking the last active tablet (if unsure, consult your doctor or pharmacist). Following these instructions, you do not need to take additional contraceptive precautions.
You can also start the day after the rest period without tablets, ring, or patch, or with inactive tablets of your current contraceptive. If you follow these instructions, make sure to use an additional contraceptive method (barrier method) during the first 7 days of taking the tablets.
You can stop your current preparation at any time and start Kerizet immediately. You will not need to take additional contraceptive precautions.
Start using Kerizet at the time you should receive the next injection or the day the implant or IUS is removed. You do not need to take additional contraceptive precautions.
You can start with Kerizet between days 21 and 28 after the birth of the baby. If you start later, make sure to use an additional contraceptive method (barrier method) during the first 7 days you take the tablets.
However, if you have already had sexual intercourse, you must rule out pregnancy before starting to take Kerizet. You can find more information about breastfeeding in the section “Pregnancy and breastfeeding” in point 2. Your doctor can also advise you.
Your doctor will advise you.
If you forgot to take Kerizet
If you forget one or more tablets in the first week of starting treatment and have had sexual intercourse during the week before forgetting the tablets, there is a possibility that you may be pregnant. Consult your doctor.
If you have gastrointestinal disorders (e.g. vomiting, intense diarrhea)
Follow the instructions for missed tablets. If you vomit or use activated charcoal within 3-4 hours after taking your Kerizet tablet or have intense diarrhea, it may not have been fully absorbed.
If you take more Kerizet than you should
No serious adverse effects have been described for taking too many Kerizet tablets at once. The symptoms that may occur are nausea, vomiting, and in young women, slight vaginal bleeding.
For more information, consult your doctor.
If you interrupt the treatment with Kerizet
You can stop taking Kerizet at any time you want. From the day you stop taking it, you will no longer be protected against pregnancy.
If you have any other doubts about the use of this product, consult your doctor or pharmacist.
Like all medications, Kerizet may cause side effects, although not everyone will experience them.
Severe side effects associated with the use of Kerizet are explained in the sections “Breast Cancer” and “Thrombosis” in point 2. “What you need to know before starting to take Kerizet.” Read this point for detailed information and consult your doctor immediately if you consider it necessary.
You should see your doctor immediately if you experience allergic reactions (hypersensitivity), including facial swelling, lips, tongue, and/or throat that cause difficulty breathing or swallowing
(angioedema and/or anaphylaxis).
Irregular vaginal bleeding may occur during the use of Kerizet, which can be a light spotting that may not even require a pad or a more intense bleeding, which is similar to a light period and requires the use of sanitary protection. It may also occur that you never have bleeding. Irregular bleeding is not a sign that Kerizet's contraceptive protection has decreased. In general, you do not need to do anything, just continue taking Kerizet. However, if the bleeding is heavy or prolonged, consult your doctor.
Users of desogestrel have reported the following side effects:
In addition to these side effects, breast secretion may appear.
