| Assessment of women prior to starting oral contraceptives (and at regular intervals thereafter) should include a personal and family medical history of each woman. Physical examination should be guided by this and by the contraindications (Section 4.3) and warnings for this product. The frequency and nature of these assessments should be based upon relevant guidelines and should be adapted to the individual woman, but should include measurement of blood pressure and, if judged appropriate by the clinician, breast, abdominal and pelvic examination including cervical cytology.Exclude likelihood of pregnancy before starting treatment.Undiagnosed vaginal bleeding should be investigated further.Oral contraceptives DO NOT protect against HIV infections (AIDS) or any other sexually transmitted disease. 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 and in consultation with the individual patient. If any of these conditions appears for the first time, or is aggravated, whilst the patient is taking Binovum, consideration should be given to discontinuing its use.− Non-breast-feeding mothers less than 21 days post-partum.− Breast-feeding mothers 6 weeks to 6 months post-partum.− Increased risk of venous thrombo-embolic disorders (See Circulatory disorders below).− Presence of multiple risk factors for arterial disease (See 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) − Past history ( 5 years ago) of migraine with 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.− History of cholestasis (related to COCs), current or medically treated gall bladder disease, porphyria.− History of breast cancer, 5 years disease-free.Diabetes mellitus with mild nephropathy, neuropathy or retinopathyCirculatory disorders Venous Thrombo-Embolism (VTE)An increased risk of venous thrombo-embolic disease (VTE) associated with the use of oral contraceptives is well established but is smaller than that associated with pregnancy, which has been estimated at 60 cases per 100,000 pregnancies. Some epidemiological studies have reported a greater risk of VTE for women using combined oral contraceptives containing desogestrel or gestodene (the so-called 'third generation' pills) than for women using pills containing levonorgestrel or norethisterone (the so-called 'second generation' pills).The spontaneous incidence of VTE in healthy non-pregnant women (not taking any oral contraceptive) is about 5 cases per 100,000 per year. The incidence in users of second generation pills is about 15 per 100,000 women per year of use. The incidence in users of third generation pills is about 25 cases per 100,000 women per year of use; this excess incidence has not been satisfactorily explained by bias or confounding. The level of all of these risks of VTE increases with age and is likely to be further increased in women with other known risk factors for VTE such as obesity. The excess risk of VTE is highest during the first year a woman ever uses a combined oral contraceptive.The risk of venous thrombo-embolism increases with− Increasing age− Family history (VTE in first degree relative less than 45 years of age)− Obesity (BMI 30 kg/m2)− Prolonged immobilisation, major surgery, any surgery to the legs, major trauma. Hormonal contraception should be discontinued 4-6 weeks before elective surgery and not recommenced until two weeks after complete remobilisation. In case of emergency surgery, thrombotic prophylaxis is usually indicated e.g. with subcutaneous heparin.There is no consensus about the role of varicose veins in VTE.Symptoms of venous thrombotic or thrombo-embolic events can include: • unusual unilateral leg pain and/or redness and swelling, typically of the calf• sudden breathlessness or onset of coughing• sudden partial or complete loss of vision. Arterial thrombo-embolism Epidemiological studies have also associated the use of COCs with an increased risk for arterial thrombo-embolism (e.g. myocardial infarction, transient ischaemic attack or stroke). This increased risk is likely to be extremely small in women who do not smoke and who do not have other risk factors of arterial thrombo-embolic complications (see below).The risk of arterial thrombo-embolic complications increases with:− Increasing age− Smoking. The risk increases with age and with heavy smoking and is more marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.− Obesity (BMI 30 kg/m2)− Hyperlipidaemia− Hypertension or a history of hypertension− Valvular heart disease− Atrial fibrillation− Family history of arterial thrombo-embolic complications− Diabetes mellitus− Sickle cell haemoglobinopathy. Symptoms of an arterial or cerebrovascular event can include:| | • sudden severe pain in the chest, whether or not it radiates to the left arm• any unusual, severe, prolonged headache, especially if it occurs for the first time or gets progressively worse• diplopia or sudden partial or complete loss of vision • slurred speech or aphasia• weakness or very marked numbness suddenly affecting one side or one part of the body• collapse with or without focal seizure, motor disturbances, vertigo. |
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 women 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 possibly be 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.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 and lipoprotein levels have been reported in oral contraceptive users. However, routine screening of women with hypertriglyceridaemia is not considered appropriate.• Diabetes without vascular involvement (although all patients with diabetes are at increased risk of arterial disease).• Decreased glucose tolerance. The oestrogen component of Binovum may cause a decrease in glucose tolerance, while the progestogens may increase insulin secretion and create insulin resistance. 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. | If any of the following conditions developed or worsened during a prior pregnancy or during previous COC use, they may occur while taking Binovum:| | • elevated blood pressure• cholestasis• herpes gestationis• otosclerosis• SLE• severe headaches. |
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 whilst 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, eg changes in temperature and cervical mucus.Excipients The tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine. | |
