Warnings
Adults:
If any of the conditions/risk factors mentioned below is present, the suitability of Cilique should be discussed with the woman.
In the event of aggravation, or first appearance of any of the conditions or risk factors, the woman should be advised to contact her doctor to determine whether the use of Cilique should be discontinued.
Exclude likelihood of pregnancy before starting treatment.
In case of undiagnosed, persistent or recurrent abnormal vaginal bleeding, appropriate measures should be conducted to rule out malignancy.
Conditions requiring supervision
- The theoretical or proven risks usually outweigh the advantages of using Combined oral contraceptives (COCs) in the conditions listed below. Consequently the decision to prescribe the COC must be made with specialist clinical judgement.
- Breast feeding (see section 4.6).
- Increased risk of venous thromboembolic disorders (See section 4.3 and “Circulatory disorders” below).
- Adequately controlled hypertension (persistently elevated baseline systolic values 140-159 mm Hg or diastolic values 90-94 mm Hg).
- Obesity (BMI ≥ 35 kg/m2).
- History of cholestasis (related to COCs), current or medically treated gall bladder disease, porphyria.
- History of breast cancer, 5 years disease-free.
Circulatory disorders
Risk of Venous Thromboembolism (VTE)
The use of any CHCs increases the risk of venous thromboembolism (VTE) compared with no use. Products that contain levonorgestrel, norgestimate (including Cilique) or norethisterone are associated with the lowest risk of VTE. The decision to use Cilique should be taken after a discussion with the woman to ensure she understands the risk of VTE with Cilique, how her current risk factors influence this risk, and that her VTE risk is highest in the first ever year of use. There is also some evidence that the risk is increased when a CHC is re-started after a break in use of 4 weeks or more.
In women who do not use a CHC and are not pregnant, about 2 out of 10,000 will develop a VTE over the period of one year. However, in any individual woman the risk may be far higher, depending on her underlying risk factors (see below).
It is estimated that out of 10,000 women who use a CHC that contains levonorgestrel, about 6 will develop a VTE in a year.
Current evidence suggests that the risk of VTE with use of norgestimate-containing CHCs is similar to the risk with levonorgestrel-containing CHCs.
This number of VTEs per year is fewer than the number expected in women during pregnancy or in the postpartum period.
VTE may be fatal in 1-2% of cases.
Extremely rarely, thrombosis has been reported to occur in CHC users in other blood vessels, e.g. hepatic, mesenteric, renal or retinal veins and arteries.
Risk factors for VTE
The risk for venous thromboembolic complications in CHC users may increase substantially in a woman with additional risk factors, particularly if there are multiple risk factors (see table).
Cilique is contraindicated if a woman has multiple risk factors that put her at high risk of venous thrombosis (see section 4.3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors – in this case her total risk of VTE should be considered. If the balance of benefits and risks is considered to be negative a CHC should not be prescribed (see section 4.3).
Table: Risk factors for VTE
| Risk factor | Comment |
| Obesity (body mass index over 30 kg/m2) | Risk increases substantially as BMI rises. Particularly important to consider if other risk factors also present. |
| Prolonged immobilisation, major surgery, any surgery to the legs or pelvis, neurosurgery, or major trauma Note: temporary immobilisation including air travel >4 hours can also be a risk factor for VTE, particularly in women with other risk factors | In these situations it is advisable to discontinue use of the patch/Pill/ring (in the case of elective surgery at least four weeks in advance) and not resume until two weeks after complete remobilisation. Another method of contraception should be used to avoid unintentional pregnancy. Antithrombotic treatment should be considered if Cilique has not been discontinued in advance. |
| Positive family history (venous thromboembolism ever in a sibling or parent especially at a relatively early age e.g. before 50) | If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use. |
| Other medical conditions associated with VTE | Cancer, systemic lupus erythematosus, haemolytic uraemic syndrome, chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis) and sickle cell disease. |
| Increasing age | Particularly above 35 years old. |
There is no consensus about the possible role of varicose veins and superficial thrombophlebitis in the onset or progression of venous thrombosis.
The increased risk of thromboembolism in pregnancy, and particularly the 6 week period of the puerperium, must be considered (for information on “Pregnancy and lactation” see section 4.6; see also graph on VTE risk).
Symptoms of VTE (deep vein thrombosis and pulmonary embolism)
In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC.
Symptoms of deep vein thrombosis (DVT) can include:
- unilateral swelling of the leg and/or foot or along a vein in the leg
- pain or tenderness in the leg which may be felt only when standing or walking
- increased warmth in the affected leg; red or discoloured skin on the leg.
Symptoms of pulmonary embolism (PE) can include:
- sudden onset of unexplained shortness of breath or rapid breathing
- sudden coughing which may be associated with haemoptysis
- sharp chest pain
- severe light headedness or dizziness
- rapid or irregular heartbeat.
Some of these symptoms (e.g. shortness of breath, coughing) are non-specific and might be misinterpreted as more common or less severe events (e.g. respiratory tract infections).
Other signs of vascular occlusion can include: sudden pain, swelling and slight blue discolouration of an extremity.
If the occlusion occurs in the eye, symptoms can range from painless blurring of vision which can progress to loss of vision. Sometimes loss of vision can occur almost immediately.
Risk of arterial thromboembolism (ATE)
Epidemiological studies have associated the use of CHCs with an increased risk for arterial thromboembolism (myocardial infarction) or for cerebrovascular accident (e.g. transient ischaemic attack, stroke). Arterial thromboembolic events may be fatal.
Risk factors for ATE
The risk of arterial thromboembolic complications or of a cerebrovascular accident in CHC users increases in women with risk factors (see table). Cilique is contraindicated if a woman has one serious or multiple risk factors for ATE that puts her at high risk of arterial thrombosis (see section 4.3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors - in this case her total risk should be considered. If the balance of benefits and risks is considered to be negative a CHC should not be prescribed (see section 4.3).
Table: Risk factors for ATE
| Risk factor | Comment |
| Increasing age | Particularly above 35 years old. |
| Smoking | Women should be advised not to smoke if they wish to use a CHC. Women over 35 years old who continue to smoke should be strongly advised to use a different method of contraception. |
| Hypertension | |
| Obesity (body mass index over 30 kg/m2) | Risk increases substantially as BMI increases. Particularly important in women with additional risk factors. |
| Positive family history (arterial thromboembolism ever in a sibling or parent especially at a relatively early age e.g. below 50 years old). | If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use. |
| Migraine | An increase in frequency or severity of migraine during CHC use (which may be prodromal of a cerebrovascular event) may be a reason for immediate discontinuation. |
| Other medical conditions associated with adverse vascular events | Diabetes mellitus, hyperhomocysteinaemia, valvular heart disease and atrial fibrillation, dyslipoproteinaemia and systemic lupus erythematosus. |
Symptoms of ATE
In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC.
Symptoms of a cerebrovascular accident can include:
- sudden numbness or weakness of the face, arm or leg, especially on one side of the body
- sudden trouble walking, dizziness, loss of balance or coordination
- sudden confusion, trouble speaking or understanding
- sudden trouble seeing in one or both eyes
- sudden, severe or prolonged headache with no known cause
- loss of consciousness or fainting with or without seizure.
Temporary symptoms suggest the event is a transient ischaemic attack (TIA).
Symptoms of myocardial infarction (MI) can include:
- pain, discomfort, pressure, heaviness, sensation of squeezing or fullness in the chest, arm, or below the breastbone
- discomfort radiating to the back, jaw, throat, arm, stomach
- feeling of being full, having indigestion or choking
- sweating, nausea, vomiting or dizziness
- extreme weakness, anxiety, or shortness of breath
- rapid or irregular heartbeats.
Medical examination/consultation
Prior to the initiation or reinstitution of Cilique, a complete medical history (including family history) should be taken and pregnancy must be ruled out. Blood pressure should be measured and a physical examination should be performed, guided by the contraindications (see section 4.3) and warnings (see section 4.4).
It is important to draw a woman's attention to the information on venous and arterial thrombosis, including the risk of Cilique compared with other CHCs, the symptoms of VTE and ATE, the known risk factors and what to do in the event of a suspected thrombosis.
The woman should also be instructed to carefully read the user leaflet and to adhere to the advice given. The frequency and nature of examinations should be based upon established practice guidelines and should be adapted to the individual woman.
Women should be advised that hormonal contraceptives do not protect against HIV infections (AIDS) and other sexually transmitted diseases.
In case of undiagnosed, persistent or recurrent abnormal vaginal bleeding, appropriate measures should be conducted to rule out malignancy.
Hepatic adenomas
Malignant hepatic tumours have been reported on rare occasions in long-term users of oral contraceptives. Benign hepatic tumours have also been associated with oral contraceptive usage. A hepatic tumour should be considered in the differential diagnosis when upper abdominal pain, enlarged liver or signs of intra-abdominal haemorrhage occur. In isolated cases, life-threatening intra-abdominal haemorrhage may occur.
Breast cancer
A meta-analysis from 54 epidemiological studies reported that there is a slightly increased relative risk (RR = 1.24) of having breast cancer diagnosed in women who are currently using COCs. The observed pattern of increased risk may be due to an earlier diagnosis of breast cancer in COC users, the biological effects of COCs or a combination of both. The additional breast cancers diagnosed in current users of COCs or in women who have used COCs in the last 10 years are more likely to be localised to the breast than those in women who never used COCs.
Breast cancer is rare among women under 40 years of age whether or not they take COCs. Whilst this background risk increases with age, the excess number of breast cancer diagnoses in current and recent COC users is small in relation to the overall risk of breast cancer (see bar chart).
The most important risk factor for breast cancer in COC users is the age women discontinue the COC; the older the age at stopping, the more breast cancers are diagnosed. Duration of use is less important and the excess risk gradually disappears during the course of the 10 years after stopping COC use such that by 10 years there appears to be no excess.
The possible increase in risk of breast cancer should be discussed with the user and weighed against the benefits of COCs taking into account the evidence that they offer substantial protection against the risk of developing certain other cancers (e.g. ovarian and endometrial cancer).
Cervical cancer
The most important risk factor for cervical cancer is persistent Human Papilloma Virus (HPV) infection. Some epidemiological studies have indicated that long-term use of COCs may further contribute to this increased risk but there continues to be controversy about the extent to which this finding is attributable to confounding effects, e.g. cervical screening and sexual behaviour including use of barrier contraceptives.
There is some theoretical concern that COCs enhance progression of Cervical Intraepithelial Neoplasia (CIN) to invasive disease. For women with diagnosed cervical cancer, COCs may be used whilst awaiting treatment.
Other tumours
Numerous epidemiological studies have been reported on the risk of ovarian and endometrial cancer in women using COCs. The evidence is clear that COCs offer substantial protection against both ovarian and endometrial cancer.
Bleeding irregularities
Breakthrough bleeding, spotting and/or absence of withdrawal flow may be encountered in patients on oral contraceptives, especially during the first three months of use.
If bleeding irregularities persist beyond three cycles or occur after previously regular cycles, non-hormonal causes should be considered, and adequate diagnostic measures are indicated to exclude malignancy or pregnancy.
Some woman may experience post-Pill amenorrhoea or oligomenorrhoea, especially when such a condition was pre-existing.
Laboratory tests
In the literature, at least a hundred different laboratory test parameters have been reported to be possibly influenced by oral contraceptive use, predominantly by the oestrogenic component. Among these are: biochemical parameters of the liver, thyroid, adrenal and renal function, plasma levels of (carrier) proteins and lipid/lipoprotein fractions and parameters of coagulation and fibrinolysis.
• Increased prothrombin and factors II, VII, VIII, IX, X, XII and XIII; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability.
• Increased thyroid binding globulin (TBG) leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 by column or by radioimmunoassay. Free T3 resin uptake is decreased, reflecting the elevated TBG, free T4 concentration is unaltered.
• Other binding proteins may be elevated in serum.
• Sex hormone-binding globulins are increased and result in elevated levels of total circulating sex steroids; however, free or biologically active levels either decrease or remain unchanged
• High-density lipoprotein (HDL-C) and total cholesterol (Total-C) may be increased, low-density lipoprotein (LDL-C) may be increased or decreased, while LDL-C/HDL-C ratio may be decreased and triglycerides may be unchanged. These effects are related to the doses of oestrogen and progestin, and to progestin type.
• Glucose tolerance may be decreased.
Reduced efficacy
The efficacy of CHCs may be reduced in the event of missed tablets (section 4.2), vomiting (section 4.2) or concomitant medication (section 4.5).
Herbal preparations containing St John's Wort (Hypericum perforatum) should not be used while taking Cilique due to the risk of decreased plasma concentrations and reduced clinical effects of Cilique (see Section 4.5 Interactions).
ALT elevations
During clinical trials with patients treated for hepatitis C virus infections (HCV) with the medicinal products containing ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin, transaminase (ALT) elevations higher than 5 times the upper limit of normal (ULN) occurred significantly more frequent in women using ethinylestradiol-containing medications such as combined hormonal contraceptives (CHCs). Additionally, also in patients treated with glecaprevir/pibrentasvir, ALT elevations were observed in women using ethinylestradiol-containing medications such as CHCs (see sections 4.3 and 4.5).
Other conditions
In the following conditions the benefit of oral contraception generally outweighs the theoretical or known risk. However, they may need to be considered before prescribing to individual patients:
• Known hyperlipidaemias. A small proportion of women will have persistent hypertriglyceridemia while on the pill. Changes in serum triglycerides, cholesterol and lipoprotein levels have been reported in users of oral contraceptives. However, routine screening of women with hypertriglyceridaemia is not considered appropriate. Women with hypertriglyceridaemia, or a family history thereof, may be at an increased risk of pancreatitis when using CHCs.
• Diabetes without vascular involvement (although all patients with diabetes are at increased risk of arterial disease).
• Oral contraceptives may cause a decrease in glucose tolerance. This effect has been shown to be directly related to oestrogen dose. Additionally, progestogens may increase insulin secretion and create insulin resistance, this effect varies with different progestational agents. However, in the non-diabetic woman, oral contraceptives appear to have no effect on fasting blood glucose. Because of these demonstrated effects, pre-diabetic and diabetic women in particular should be carefully monitored while taking oral contraceptives.
• Asymptomatic gall bladder disease or cholecystectomy.
• Benign liver tumours (focal nodular hyperplasia). There is limited, direct evidence that hormonal contraceptive use does not influence either progression or regression of liver lesions among women with focal nodular hyperplasia.
• Migraine without focal aura. The onset or exacerbation of migraine or development of headache with a new pattern which is recurrent, persistent or severe requires discontinuation of oral contraceptives and evaluation of the cause.
• Crohn's disease and ulcerative colitis have been associated with CHC use.
• Exogenous estrogens may induce or exacerbate symptoms of hereditary and acquired angioedema.
If any of the following conditions developed or worsened during a prior pregnancy or during previous COC use, they may occur while taking Cilique:
• elevated blood pressure
• cholestasis
• porphyria
• herpes gestationis
• otosclerosis
• SLE
• severe headaches
• haemolytic uraemic syndrome
• Sydenham's chorea
Chloasma
Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking this preparation. Chloasma is often not fully reversible.
Additional contraceptive precautions
When additional contraceptive precautions are required, the patient should be advised either not to have sex, or to use a cap plus spermicide or for her partner to use a condom. Rhythm methods should not be advised as the Pill disrupts the usual cyclical changes associated with the natural menstrual cycle, e.g changes in temperature and cervical mucus.
Psychiatric Disorders:
Depressed mood and depression are well-known undesirable effects of hormonal contraceptive use (see section 4.8). Depression can be serious and is a well-known risk factor for suicidal behaviour and suicide. Women should be advised to contact their physician in case of mood changes and depressive symptoms, including shortly after initiating the treatment.
Excipients: The tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, the total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
