The user of the medicinal product can also help by reporting any adverse reactions that occur after taking the medicinal product. To find out how to report adverse reactions, see section 4.
Clormetin is a hormonal contraceptive for oral use. An oral contraceptive that contains two hormones, like Clormetin, is also called a combined hormonal contraceptive. Each of the 21 coated tablets in the packaging for one cycle contains the same amount of both hormones, and therefore Clormetin is also called a monophasic preparation. Hormonal contraceptives, such as Clormetin, do not protect against AIDS (HIV infection) and other sexually transmitted diseases. Only condoms can protect against these diseases.
Before starting to take Clormetin, you should read the information about blood clots in section 2. It is especially important to read about the symptoms of a blood clot (see section 2 "Blood clots").
Before starting to take Clormetin, your doctor will perform a general and gynecological examination, rule out pregnancy, and decide, taking into account contraindications and precautions, whether you can take Clormetin. During the use of Clormetin, such an examination should be repeated once a year.
You should not take Clormetin if you have any of the conditions listed below. If you have any of the conditions listed below, you should inform your doctor. Your doctor will discuss with you which other contraceptive method will be more suitable for you.
If any of the above conditions occur during the use of Clormetin, you should stop taking Clormetin immediately.
You should not take Clormetin or stop taking it immediately if you have one or more serious risk factors for blood clots.
Before starting to take Clormetin, you should discuss it with your doctor or pharmacist.
When should you contact your doctor?
If these symptoms occur or worsen during the use of Clormetin, you should also tell your doctor.
The use of combined hormonal contraceptives, such as Clormetin, is associated with an increased risk of blood clots, compared to when these medicinal products are not used. In rare cases, a blood clot can block a blood vessel and cause serious complications.
Blood clots can occur
Not all patients who have a blood clot will recover fully. In rare cases, the effects of a blood clot can be permanent or, very rarely, fatal.
You should contact your doctor immediately if you notice any of the following symptoms.
Is the patient experiencing any of these symptoms? | What is the patient likely suffering from? |
| Deep vein thrombosis |
| Pulmonary embolism |
| |
Symptoms that occur most often in one eye:
| Retinal vein thrombosis (blood clot in the eye) |
| Heart attack |
| Stroke |
| Blood clots blocking other blood vessels |
The risk of forming a blood clot in a vein is highest during the first year of use of combined hormonal contraceptives for the first time. The risk may also be higher when resuming the use of combined hormonal contraceptives (the same or a different medicinal product) after a break of 4 weeks or more.
After the first year, the risk decreases, but it is always higher compared to when combined hormonal contraceptives are not used.
If you stop taking Clormetin, the risk of blood clots returns to normal within a few weeks.
The risk depends on the natural risk of venous thromboembolism and the type of combined hormonal contraceptive used.
The overall risk of blood clots in the legs or lungs associated with Clormetin is small.
Risk of blood clots in a year | |
Women who do not use combined hormonal tablets/patches/rings and are not pregnant | About 2 out of 10,000 women |
Women using combined hormonal contraceptive tablets containing levonorgestrel, norethisterone, or norgestimate | About 5-7 out of 10,000 women |
Women using Clormetin | Not yet known |
If a woman notices an increased frequency or severity of migraine attacks during the use of Clormetin (which may indicate disturbances in the brain's blood supply), she should consult her doctor as soon as possible. The doctor may recommend stopping the use of Clormetin.
The risk of blood clots associated with Clormetin is small, but some factors can increase this risk. The risk is higher:
The risk of blood clots increases with the number of risk factors present in the patient.
Long-haul flights (>4 hours) may temporarily increase the risk of blood clots, especially if the patient has another risk factor.
It is essential to tell your doctor if any of the above risk factors apply to you, even if you are not sure. Your doctor may decide to stop the use of Clormetin.
You should inform your doctor if any of the above conditions change during the use of Clormetin, e.g., if someone in your immediate family is diagnosed with a blood clot without a known cause or if you gain significant weight.
Similarly to blood clots in veins, blood clots in an artery can cause serious consequences, such as a heart attack or stroke.
It is essential to note that the risk of heart attack or stroke associated with Clormetin is very small, but it may increase:
If you have more than one of the above conditions or if any of them are severe, the risk of blood clots may be even higher.
You should inform your doctor if any of the above conditions change during the use of Clormetin, e.g., if you start smoking, someone in your immediate family is diagnosed with a blood clot without a known cause, or if you gain significant weight.
Cancer
In several studies, an increased risk of cervical cancer has been found in women infected with a specific sexually transmitted virus (human papillomavirus) and long-term users of contraceptives. However, it has not been clarified what other factors may influence the development of cervical cancer (e.g., different numbers of sexual partners and the use of barrier methods of contraception).
Studies have shown a slightly increased risk of breast cancer in women taking combined hormonal contraceptives. Within 10 years after stopping the use of these medicinal products, the risk returns to the level of risk associated with age. Since breast cancer is rare in women under 40 years old, the increase in the number of diagnosed cases of this disease in women currently or previously using hormonal contraceptives is small compared to the risk of breast cancer over a lifetime.
In rare cases, the use of hormonal contraceptives has led to the development of benign or, even more rarely, malignant liver tumors. They can cause life-threatening internal bleeding. If you experience severe, persistent abdominal pain, you should contact your doctor.
Psychiatric disorders:
Some women using hormonal contraceptives, including Clormetin, 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.
Many women taking hormonal contraceptives experience a slight increase in blood pressure. If your blood pressure increases significantly during the use of Clormetin, your doctor will recommend stopping the use of Clormetin and prescribe a medicinal product to lower your blood pressure. You can resume taking Clormetin when your blood pressure returns to normal.
Women who have had impetigo herpetiformis (a skin condition) during a previous pregnancy may experience it again while taking hormonal contraceptives.
If you or a family member has a disorder of fat metabolism (hypertriglyceridemia), there is an increased risk of pancreatitis. If you experience acute or chronic liver function disorders, your doctor may recommend stopping the use of Clormetin until liver function tests return to normal. If you have had jaundice during a previous pregnancy or while taking hormonal contraceptives and it recurs, your doctor will recommend stopping the use of Clormetin.
If you are taking Clormetin and have diabetes, and your blood sugar levels are well controlled, your doctor should carefully monitor your condition while you are taking Clormetin.
A change in your antidiabetic treatment may be necessary.
Brown spots on the skin (chloasma) may occur, especially if they occurred during a previous pregnancy. If you are prone to chloasma, you should avoid direct exposure to sunlight and ultraviolet radiation while taking Clormetin.
Unfavorable effect on existing diseases
Special medical supervision may be necessary if you have:
You should tell your doctor if any of the above diseases have occurred in the past, are present, or occur while taking Clormetin.
Efficacy
The contraceptive effect may be affected if the contraceptive is taken irregularly, if vomiting or diarrhea occurs after taking the medicinal product (see section 3), or if you are taking certain other medicinal products (see section 2). In very rare cases, the contraceptive effect may be affected by metabolic disorders.
Even if hormonal contraceptives are taken correctly, they do not guarantee complete protection against pregnancy.
Irregular bleeding
During the use of hormonal contraceptives, irregular vaginal bleeding (bleeding and/or spotting) may occur, especially during the first few months of use. You should inform your doctor if irregular bleeding persists after 3 months of use or if it occurs after previously regular menstrual cycles.
Spotting may also indicate a decrease in contraceptive efficacy.
In some patients, withdrawal bleeding may not occur after 21 days of taking Clormetin. If Clormetin has been taken according to the instructions in section 3 below, pregnancy is unlikely. However, if Clormetin was not taken according to the instructions before the first missed withdrawal bleeding, you should ensure that you are not pregnant before continuing to take Clormetin.
You should tell your doctor or pharmacist about all medicinal products you are currently taking or have recently taken, as well as any medicinal products you plan to take.
Do not take Clormetin if you have hepatitis C and are taking medicinal products containing ombitasvir/paritaprevir/ritonavir and dasabuvir or glecaprevir/pibrentasvir, as this may cause abnormal liver function test results in the blood (elevated liver enzyme alanine aminotransferase (ALT) activity).
Before starting to take these medicinal products, your doctor will prescribe a different contraceptive method.
You can resume taking Clormetin after about 2 weeks after stopping these medicinal products. See section "When not to take Clormetin".
Certain medicinal products may affect the blood levels of Clormetin and cause a decrease in its efficacy in preventing pregnancy or cause unexpected bleeding. These include medicinal products used to treat:
Medicinal products that stimulate bowel movements (e.g., metoclopramide) and activated charcoal may change the absorption of the active substances of Clormetin.
During treatment with the above-mentioned medicinal products, you should use additional mechanical methods of contraception (e.g., condoms). Additional mechanical methods of contraception should be used throughout the time of concurrent use of these medicinal products and for 28 days after stopping their use.
If concurrent use of medicinal products will continue until the end of the tablets in the current pack of the combined hormonal contraceptive, you should start the next pack of Clormetin without the usual break in tablet-taking.
If long-term treatment with the above-mentioned medicinal products is necessary, you should use non-hormonal methods of contraception. You should ask your doctor or pharmacist for advice.
Interactions between Clormetin and other medicinal products may increase or worsen the adverse reactions of Clormetin. The following medicinal products may have an unfavorable effect on the tolerance of Clormetin:
Clormetin may affect the efficacy of other medicinal products. The efficacy or tolerance of the following medicinal products may be reduced by the use of Clormetin:
You should also read the package leaflets of other medicinal products prescribed by your doctor.
You should inform your doctor if you are taking insulin or other medicinal products that lower blood sugar levels. A change in the dosage of these medicinal products may be necessary.
You should remember that this information also applies to situations where one of these active substances was used shortly before starting to take Clormetin.
During the use of Clormetin, the results of some tests that determine liver, adrenal, and thyroid function, certain blood proteins, carbohydrate metabolism parameters, and blood coagulation parameters may change. Therefore, before having blood tests, you should tell your doctor that you are taking Clormetin.
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 taking this medicinal product.
The use of Clormetin is not recommended during pregnancy.
If you become pregnant while taking Clormetin, you should stop taking it immediately. However, previous use of Clormetin is not a reason to terminate the pregnancy.
Remember that during breastfeeding, while taking Clormetin, milk production may decrease, and the composition of the milk may change. Very small amounts of the active substances may pass into the milk. Hormonal contraceptives, such as Clormetin, should only be used after weaning.
There is no known unfavorable effect of combined hormonal contraceptives on the ability to drive and use machines.
If you have been diagnosed with an intolerance to some sugars, you should consult your doctor before taking this medicinal product.
This medicinal product should always be taken exactly as prescribed by your doctor. If you are unsure, you should consult your doctor or pharmacist.
