for
Femoston-conti is a Hormone Replacement Therapy (HRT). It contains two types of female hormones, an oestrogen called estradiol and a progestogen called dydrogesterone. Femoston-conti is used in postmenopausal women with at least 12 months since their last natural period. Femoston-conti is used for Relief of symptoms occurring after menopause During the menopause, the amount of the oestrogen produced by a woman's body drops. This can cause symptoms such as hot face, neck and chest ("hot flushes"). Femoston-conti alleviates these symptoms after menopause. You will only be prescribed Femoston-conti if your symptoms seriously hinder your daily life. Prevention of osteoporosis After the menopause some women may develop fragile bones (osteoporosis). You should discuss all available options with your doctor. If you are at an increased risk of fractures due to osteoporosis and other medicines are not suitable for you, you can use Femoston-conti to prevent osteoporosis after menopause.

e Femoston-conti
Medical history and regular check-ups The use of HRT carries risks which need to be considered when deciding whether to start taking it, or whether to carry on taking it. The experience in treating women with a premature menopause (due to ovarian failure or surgery) is limited. If you have a premature menopause the risks of using HRT may be different. Please talk to your doctor. Before you start (or restart) HRT, your doctor will ask about your own and your family's medical history. Your doctor may decide to perform a physical examination. This may include an examination of your breasts and/or an internal examination, if necessary. Once you have started on Femoston-conti you should see your doctor for regular check-ups (at least once a year). At these check-ups, discuss with your doctor the benefits and risks of continuing with Femostonconti. Go for regular breast screening, as recommended by your doctor. DO NOT take Femoston-conti if any of the following applies to you. If you are not sure about any of the points below, talk to your doctor before taking Femoston-conti. Do not take Femoston-conti –
if you have meningioma or have ever been diagnosed with a meningioma (a generally benign tumour of the tissue layer between the brain and the skull) if you have or have ever had breast cancer, or if you are suspected of having it
–
if you have cancer which is sensitive to oestrogens, such as cancer of the womb lining (endometrium), or if you are suspected of having it
–
if you have any unexplained vaginal bleeding
–
if you have excessive thickening of the womb lining (endometrial hyperplasia) that is not being treated
–
if you have or have ever had a blood clot in a vein (thrombosis), such as in the legs (deep venous thrombosis) or the lungs (pulmonary embolism)
–
if you have a blood clotting disorder (such as protein C, protein S, or antithrombin deficiency)
–
if you have or recently have had a disease caused by blood clots in the arteries such as a heart attack, stroke or angina
–
if you have or have ever had a liver disease and your liver function tests have not returned to normal
–
if you have a rare blood problem called "porphyria" which is passed down in families (inherited)
–
if you are allergic (hypersensitive) to estradiol, dydrogesterone or any of the other ingredients of this medicine (listed in section 6)
If any of the above conditions appear for the first time while taking Femoston-conti, stop taking it at once and consult your doctor immediately. Warnings and precautions
Talk to your doctor or pharmacist before taking Femoston-conti if you have ever had any of the following problems, before you start the treatment, as these may return or become worse during treatment with Femoston-conti. If so, you should see your doctor more often for check-ups: –
fibroids inside your womb
–
growth of womb lining outside your womb (endometriosis) or a history of excessive growth of the womb lining (endometrial hyperplasia)
–
increased risk of developing blood clots (see "Blood clots in a vein (thrombosis)")
–
increased risk of getting an oestrogen-sensitive cancer (such as having a mother, sister or grandmother who has had breast cancer)
–
high blood pressure
–
a liver disorder such as a benign liver tumour
–
diabetes
–
gallstones
–
migraine or severe headaches
–
a disease of the immune system that affects many organs of the body (systemic lupus erythematosus, SLE)
–
epilepsy
–
asthma
–
a disease affecting the eardrum and hearing (otosclerosis)
–
a very high level of fat in your blood (triglycerides)
–
fluid retention due to cardiac or kidney problems
–
hereditary and acquired angioedema
Meningioma Use of Femoston-conti has been linked to the development of a generally benign tumour of the tissue layer between the brain and the skull (meningioma). If you are diagnosed with meningioma, your doctor will stop your treatment with Femoston-conti (see section 'Do not take…'). If you notice any symptoms such as changes in vision (e.g. seeing double or blurriness), hearing loss or ringing in the ears, loss of smell, headaches that worsen with time, memory loss, seizures, weakness in your arms or legs, you must tell your doctor straightaway. Stop taking Femoston-conti and see a doctor immediately If you notice any of the following when taking HRT:
yellowing of your skin or the whites of your eyes (jaundice). These may be signs of a liver disease
–
swollen face, tongue and/or throat and/or difficulty swallowing or hives, together with difficulty breathing which are suggestive of an angioedema
–
a large rise in your blood pressure (symptoms may be headache, tiredness, dizziness).
–
migraine-like headaches which happen for the first time.
–
if you become pregnant
–
if you notice signs of a blood clot, such as: painful swelling and redness of the legs sudden chest pain difficulty in breathing
For more information, see 'Blood clots in a vein (thrombosis)' Note: Femoston-conti is not a contraceptive. If it is less than 12 months since your last menstrual period or you are under 50 years old, you may still need to use additional contraception to prevent pregnancy. Speak to your doctor for advice. HRT and cancer Excessive thickening of the lining of the womb (endometrial hyperplasia) and cancer of the lining of the womb (endometrial cancer) Taking oestrogen-only HRT will increase the risk of excessive thickening of the lining of the womb (endometrial hyperplasia) and cancer of the womb lining (endometrial cancer). The progestogen in Femoston-conti protects you from this extra risk. Irregular bleeding You may have irregular bleeding or drops of blood (spotting) during the first 3-6 months of taking Femoston-conti. However, if the irregular bleeding:
For women aged 50 who start taking oestrogen-only HRT for 10 years, there will be 34 cases in 1000 users (i.e. an extra 7 cases) For women aged 50 who start taking oestrogen-progestogen HRT for 10 years, there will be 48 cases in 1000 users (i.e. an extra 21 cases). Regularly check your breasts. See your doctor if you notice any changes such as:
Heart disease (heart attack) There is no evidence that HRT will prevent a heart attack. Women over the age of 60 years who use oestrogen-progestogen HRT are slightly more likely to develop heart disease than those not taking any HRT. Stroke The risk of getting a stroke is about 1.5-times higher in HRT users than in non-users. The number of extra cases of stroke due to use of HRT will increase with age. Compare Looking at women in their 50s who are not taking HRT, on average, 8 in 1000 would be expected to have a stroke over a 5-year period. For women in their 50s who are taking HRT, there will be 11 cases in 1000 users, over 5 years (i.e. an extra 3 cases). Other conditions HRT will not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start using HRT after the age of 65. Speak to your doctor for advice. Tell your doctor if you have or have had any of the following medical conditions since he will have to monitor you more closely: heart disease kidney impairment higher than normal levels of certain blood fats (hypertriglyceridemia) Children Femoston-conti is not intended for use in children. Other medicines and Femoston-conti Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Some medicines may interfere with the effect of Femoston-conti. This might lead to irregular bleeding. This applies to the following medicines:
a medicine for epilepsy (lamotrigine), as this could increase frequency of seizures medicines for Hepatitis C virus (HCV) (such as combination regimens ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin; glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir) may cause increases in liver function blood test results (increase in ALT liver enzyme) in women using CHCs containing ethinylestradiol. Femoston-conti contains estradiol instead of ethinylestradiol. It is not known whether an increase in ALT liver enzyme can occur when using Femoston-conti with this HCV combination regimen.
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines including medicines obtained without a prescription, herbal medicines or other natural products. Your doctor will advise you. Laboratory tests If you need a blood test, tell your doctor or the laboratory staff that you are taking Femoston-conti, because this medicine can affect the results of some tests. Femoston-conti with food and drink Femoston-conti can be taken with or without food. Pregnancy and breast-feeding Femoston-conti is for use in postmenopausal women only. If you become pregnant stop taking Femoston-conti and contact your doctor. Femoston-conti is not indicated for use during breast-feeding. Driving and using machines The effect of Femoston-conti on driving or using machinery has not been studied. An effect is unlikely. Femoston-conti tablets contain lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product. 3.

Hormone replacement therapy (HRT) for oestrogen deficiency symptoms in postmenopausal women at least 12 months since last menses.
Prevention of osteoporosis in postmenopausal women at high risk of future fractures who are intolerant of, or contraindicated for, other medicinal products approved for the prevention of osteoporosis. (See also section 4.4)
The experience in treating women older than 65 years is limited.
Femoston-conti 1mg/ 5mg film-coated tablets are a continuous combined HRT for oral use.
The oestrogen and the progestogen are given every day without interruption.
The dosage is one tablet per day for a 28 day cycle.
Femoston-conti 1mg/ 5mg film-coated tablets should be taken continuously without a break between packs.
For initiation and continuation of treatment of postmenopausal symptoms, the lowest effective dose for the shortest duration (see also section 4.4) should be used.
Continuous combined treatment may be started with Femoston-conti 1mg/ 5mg film-coated tablets depending on the time since menopause and severity of symptoms. Women experiencing a natural menopause should commence treatment with Femoston-conti 1mg/ 5mg film-coated tablets 12 months after their last natural menstrual bleed. For surgically induced menopause, treatment may start immediately.
Depending on the clinical response, the dosage can subsequently be adjusted.
Patients changing from a continuous sequential or cyclical preparation should complete the 28 day cycle and then change to Femoston-conti 1mg/ 5mg film-coated tablets.Patients changing from another continuous combined preparation may start therapy at any time.
If a dose has been forgotten, it should be taken as soon as possible. If more than 12 hours have elapsed, treatment should be continued with the next tablet without taking the forgotten tablet. The likelihood of breakthrough bleeding or spotting may be increased.
Femoston-conti 1mg/ 5mg film-coated tablets can be taken irrespectively of food intake.
Paediatric population:
There is no relevant indication for the use of Femoston-conti 1mg/ 5mg film-coated tablets in the paediatric population.
• Known, past or suspected breast cancer
• Known or suspected oestrogen-dependent malignant tumours (e.g. endometrial cancer)
• Undiagnosed genital bleeding
• Untreated endometrial hyperplasia
• Previous or current venous thromboembolism (deep venous thrombosis, pulmonary embolism)
• Known thrombophilic disorders (e.g. protein C, protein S, or antithrombin deficiency, see section 4.4)
• Active or recent arterial thromboembolic disease (e.g. angina, myocardial infarction)
• Acute liver disease or a history of liver disease as long as the liver function tests have failed to return to normal
• Porphyria
• Known hypersensitivity to the active substances or to any of the excipients listed in section 6.1
• Meningioma or history of meningioma
For the treatment of postmenopausal symptoms, HRT should only be initiated for symptoms that adversely affect quality of life. In all cases, a careful appraisal of the risks and benefits should be undertaken at least annually and HRT should only be continued as long as the benefit outweighs the risk.
Evidence regarding the risks associated with HRT in the treatment of premature menopause is limited. Due to the low level of absolute risk in younger women, however, the balance of benefits and risks for these women may be more favourable than in older women.
Medical examination/follow up
Before initiating or re-instituting HRT, a complete personal and family medical history should be taken. Physical (including pelvic and breast) examination should be guided by this and by the contraindications and warnings for use. During treatment, periodic check-ups are recommended of a frequency and nature adapted to the individual woman. Women should be advised what changes in their breasts should be reported to their doctor or nurse (see “Breast cancer” below). Investigations, including appropriate imaging tools, e.g. mammography, should be carried out in accordance with currently accepted screening practices, modified to the clinical needs of the individual.
Conditions which need supervision
If any of the following conditions are present, have occurred previously, and/or have been aggravated during pregnancy or previous hormone treatment, the patient should be closely supervised. It should be taken into account that these conditions may recur or be aggravated during treatment with Femoston-conti 1mg/ 5mg film-coated tablets, in particular:
• Leiomyoma (uterine fibroids) or endometriosis
• Risk factors for thromboembolic disorders (see below)
• Risk factors for oestrogen-dependent tumours, e.g. 1st degree heredity for breast cancer
• Hypertension
• Liver disorders (e.g. liver adenoma)
• Diabetes mellitus with or without vascular involvement
• Cholelithiasis
• Migraine or (severe) headache
• Systemic lupus erythematosus
• A history of endometrial hyperplasia (see below)
• Epilepsy
• Asthma
• Otosclerosis
Meningioma
The occurrence of meningiomas (single and multiple) has been reported in association with use of Femoston-conti 1mg/ 5mg film-coated tablets. Patients should be monitored for signs and symptoms of meningiomas in accordance with clinical practice. If a patient is diagnosed with meningioma, any estradiol/dydrogesterone containing treatment must be stopped (see section 4.3). Tumour shrinkage has been observed after treatment discontinuation.
Reasons for immediate withdrawal of therapy
Therapy should be discontinued in case a contraindication is discovered and in the following situations:
• Jaundice or deterioration in liver function
• Significant increase in blood pressure
• New onset of migraine-type headache
• Pregnancy
Endometrial hyperplasia and carcinoma
• In women with an intact uterus the risk of endometrial hyperplasia and carcinoma is increased when oestrogens are administered alone for prolonged periods. The reported increase in endometrial cancer risk among oestrogen-only users varies from 2- to 12-fold greater compared with non-users, depending on the duration of treatment and oestrogen dose (see section 4.8). After stopping treatment risk may remain elevated for at least 10 years.
• The addition of a progestogen cyclically for at least 12 days per month /28 day cycle or continuous combined oestrogen-progestogen therapy in non-hysterectomised women can prevent the excess risk associated with oestrogen-only HRT.
• Break-through bleeding and spotting may occur during the first months of treatment. If break-through bleeding or spotting appears after some time on therapy, or continues after treatment has been discontinued, the reason should be investigated, which may include endometrial biopsy to exclude endometrial malignancy.
Breast cancer
The overall evidence shows an increased risk of breast cancer in women taking combined oestrogen-progestogen or oestrogen-only HRT, that is dependent on the duration of taking HRT.
Combined oestrogen-progestogen therapy:
• The randomised placebo-controlled trial, the Women's Health Initiative study (WHI), and a meta-analysis of prospective epidemiological studies are consistent in finding an increased risk of breast cancer in women taking combined oestrogen-progestogen for HRT that becomes apparent after about 3 (1-4) years (see section 4.8).
Oestrogen-only therapy:
• The WHI trial found no increase in the risk of breast cancer in hysterectomised women using oestrogen-only HRT. Observational studies have mostly reported a small increase in risk of having breast cancer diagnosed that is lower than that found in users of oestrogen-progestogen combinations (see section 4.8).
Results from a large meta-analysis showed that after stopping treatment, the excess risk will decrease with time and the time needed to return to baseline depends on the duration of prior HRT use. When HRT was taken for more than 5 years, the risk may persist for 10 years or more.
HRT, especially oestrogen-progestogen combined treatment, increases the density of mammographic images which may adversely affect the radiological detection of breast cancer.
Ovarian cancer
Ovarian cancer is much rarer than breast cancer. Epidemiological evidence from a large meta-analysis suggests a slightly increased risk in women taking oestrogen-only or combined oestrogen-progestogen HRT, which becomes apparent within 5 years of use and diminishes over time after stopping. Some other studies, including the WHI trial suggest that use of combined HRTs may be associated with a similar, or slightly smaller, risk (see section 4.8).
Venous thromboembolism
• HRT is associated with a 1.3- to 3-fold risk of developing venous thromboembolism (VTE), i.e. deep vein thrombosis or pulmonary embolism. The occurrence of such an event is more likely in the first year of HRT than later (see section 4.8).
• Patients with known thrombophilic states have an increased risk of VTE and HRT may add to this risk. HRT is therefore contraindicated in these patients (see section 4.3).
• Generally recognised risk factors for VTE include: use of oestrogens, older age, major surgery, prolonged immobilisation, obesity (BMI>30 kg/m2), pregnancy/postpartum period, systemic lupus erythematosus (SLE), and cancer. There is no consensus about the possible role of varicose veins in VTE.As in all postoperative patients, prophylactic measures need to be considered to prevent VTE following surgery. If prolonged immobilisation is to follow elective surgery, temporarily stopping HRT 4 to 6 weeks earlier is recommended. Treatment should not be restarted until the woman is completely mobilised.
• In women with no personal history of VTE but with a first degree relative with a history of thrombosis at young age, screening may be offered after careful counselling regarding its limitations (only a proportion of thrombophilic defects are identified by screening).If a thrombophilic defect is identified which segregates with thrombosis in family members or if the defect is 'severe' (e.g. antithrombin, protein S, or protein C deficiencies or a combination of defects) HRT is contraindicated.
• Women already on anticoagulant treatment require careful consideration of the benefit-risk of use of HRT.
• If VTE develops after initiating therapy, the drug should be discontinued. Patients should be told to contact their doctors immediately when they are aware of a potential thromboembolic symptom (e.g. painful swelling of a leg, sudden pain in the chest, dyspnoea).
Coronary artery disease (CAD)
There is no evidence from randomised controlled trials of protection against myocardial infarction in women with or without existing CAD who received combined oestrogen-progestogen or oestrogen-only HRT.
Combined oestrogen-progestogen therapy:
The relative risk of CAD during use of combined oestrogen-progestogen HRT is slightly increased. As the baseline absolute risk of CAD is strongly dependent on age, the number of extra cases of CAD due to oestrogen-progestogen use is very low in healthy women close to menopause, but will rise with more advanced age.
Oestrogen-only:
Randomised controlled data found no increased risk of CAD in hysterectomised women using oestrogen-only therapy.
Ischaemic Stroke
Combined oestrogen-progestogen and oestrogen-only therapy are associated with an up to 1.5-fold increase in risk of ischaemic stroke. The relative risk does not change with age or time since menopause. However, as the baseline risk of stroke is strongly age-dependent, the overall risk of stroke in women who use HRT will increase with age (see section 4.8).
ALT elevations
During clinical trials with patients treated for hepatitis C virus (HCV) infections with the combination regimen ombitasvir/paritaprevir/ritonavir and dasabuvir with and without ribavirin, ALT elevations greater than 5 times the upper limit of normal (ULN) were significantly more frequent in women using ethinylestradiol-containing medicinal products such as CHCs. Additionally, also in patients treated with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir, ALT elevations were observed in women using ethinylestradiol-containing medications such as CHCs. Women using medicinal products containing oestrogens other than ethinylestradiol, such as estradiol, and ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin had a rate of ALT elevation similar to those not receiving any oestrogens; however, due to the limited number of women taking these other oestrogens, caution is warranted for co-administration with the following combination drug regimens: ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin,glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir. (see section 4.5).
Other conditions
• Oestrogens may cause fluid retention, and therefore patients with cardiac or renal dysfunction should be carefully observed.
• Women with pre-existing hypertriglyceridaemia should be followed closely during oestrogen replacement or hormone replacement therapy, since rare cases of large increases of plasma triglycerides leading to pancreatitis have been reported with oestrogen therapy in this condition.
• Exogenous oestrogens may induce or exacerbate symptoms of hereditary and acquired angioedema.
• Oestrogens increase thyroid binding globulin (TBG), leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 levels (by column or by radio-immunoassay) or T3 levels (by radio-immunoassay). T3 resin uptake is decreased, reflecting the elevated TBG. Free T4 and free T3 concentrations are unaltered. Other binding proteins may be elevated in serum, i.e. corticoid binding globulin (CBG), sex-hormone-binding globulin (SHBG) leading to increased circulating corticosteroids and sex steroids, respectively. Free or biological active hormone concentrations are unchanged. Other plasma proteins may be increased (angiotensinogen/renin substrate, alpha-I-antitrypsin, ceruloplasmin).
• HRT use does not improve cognitive function. There is some evidence of increased risk of probable dementia in women who start using continuous combined or oestrogen-only HRT after the age of 65.
• Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.
This oestrogen-progestogen combination treatment is not a contraceptive.
No interaction studies have been performed.
The efficacy of oestrogens and progestogens might be impaired:
• The metabolism of oestrogens and progestogens may be increased by concomitant use of substances known to induce drug-metabolising enzymes, specifically P450 enzymes, such as anticonvulsants (e.g. phenobarbital, carbamazepin, phenytoin) and anti-infectives (e.g. rifampicin, rifabutin, nevirapine, efavirenz).
• Ritonavir and nelfinavir, although known as strong inhibitors, by contrast exhibit inducing properties when used concomitantly with steroid hormones.
• Herbal preparations containing St John's Wort (Hypericum perforatum) may induce the metabolism of oestrogens and progestogens.
• Clinically, an increased metabolism of oestrogens and progestogens may lead to decreased effect and changes in the uterine bleeding profile.
Effect of HRT with oestrogens on other medicinal products
Hormone contraceptives containing oestrogens have been shown to significantly decrease plasma concentrations of lamotrigine when co-administered due to induction of lamotrigine glucuronidation. This may reduce seizure control. Although the potential interaction between hormone replacement therapy and lamotrigine has not been studied, it is expected that a similar interaction exists, which may lead to a reduction in seizure control among women taking both medicinal products together.
Pharmacodynamic interactions
During clinical trials with the HCV combination drug regimen ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin, ALT elevations greater than 5 times the upper limit of normal (ULN) were significantly more frequent in women using ethinylestradiol-containing medicinal products such as CHCs. Additionally, also with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir, ALT elevations were observed in women using ethinylestradiol-containing medications such as CHCs.
Women using medicinal products containing oestrogens other than ethinylestradiol, such as estradiol, and ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin had a rate of ALT elevation similar to those not receiving any oestrogens; however, due to the limited number of women taking these other oestrogens, caution is warranted for co-administration with the following combination drug regimens: ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin, glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir. (see section 4.4).
Pregnancy
Femoston-conti 1mg/ 5mg film-coated tablets are not indicated during pregnancy. If pregnancy occurs during medication with Femoston-conti 1mg/ 5mg film-coated tablets, treatment should be withdrawn immediately.
There are no adequate data from the use of estradiol/dydrogesterone in pregnant women. The results of most epidemiological studies to date relevant to inadvertent fetal exposure to combinations of oestrogens and progestogens indicate no teratogenic or foetotoxic effect.
Breast Feeding
Femoston-conti 1mg/ 5mg film-coated tablets are not indicated during lactation.
Fertility
Femoston-conti 1mg/ 5mg is not indicated during fertility.
Femoston-conti 1mg/ 5mg film-coated tablets have no or negligible influence on the ability to drive and/or to use machines.

Breast cancer risk
• An up to 2-fold increased risk of having breast cancer diagnosed is reported in women taking combined oestrogen-progestogen therapy for more than 5 years.
• The increased risk in users of oestrogen-only therapy is lower than that seen in users of oestrogen-progestogen combinations.
• The level of risk is dependent on the duration of use (see section 4.4).
• Absolute risk estimations based on results of the largest randomised placebo-controlled trial (WHI-study) and the largest meta-analysis of prospective epidemiological studies are presented.

* WHI study in women with no uterus, which did not show an increase in risk of breast cancer
‡When the analysis was restricted to women who had not used HRT prior to the study there was no increased risk apparent during the first 5 years of treatment: after 5 years the risk was higher than in non-users.
Endometrial cancer risk
Postmenopausal women with a uterus:
The endometrial cancer risk is about 5 in every 1000 women with a uterus not using HRT.
In women with a uterus, use of oestrogen-only HRT is not recommended because it increases the risk of endometrial cancer (see section 4.4). Depending on the duration of oestrogen-only use and oestrogen dose, the increase in risk of endometrial cancer in epidemiology studies varied from between 5 and 55 extra cases diagnosed in every 1000 women between the ages of 50 and 65.
Adding a progestogen to oestrogen-only therapy for at least 12 days per cycle can prevent this increased risk. In the Million Women Study the use of five years of combined (sequential or continuous) HRT did not increase the risk of endometrial cancer (RR of 1.0 (0.8 - 1.2)).
Ovarian cancer
Use of oestrogen-only or combined oestrogen-progestogen HRT has been associated with a slightly increased risk of having ovarian cancer diagnosed (see section 4.4).
A meta-analysis from 52 epidemiological studies reported an increased risk of ovarian cancer in women currently using HRT compared to women who have never used HRT (RR 1.43, 95% CI 1.31-1.56). For women aged 50 to 54 years taking 5 years of HRT, this results in about 1 extra case per 2000 users. In women aged 50 to 54 who are not taking HRT, about 2 women in 2000 will be diagnosed with ovarian cancer.
Risk of venous thromboembolism
HRT is associated with a 1.3- to 3-fold increased relative risk of developing venous thromboembolism (VTE), i.e. deep vein thrombosis or pulmonary embolism. The occurrence of such an event is more likely in the first year of using HRT (see section 4.4). Results of the WHI studies are presented:

Risk of coronary artery disease
The risk of coronary artery disease is slightly increased in users of combined oestrogen-progestogen HRT over the age of 60 (see section 4.4).
Risk of ischaemic stroke
The use of oestrogen-only and oestrogen+progestogen therapy is associated with an up to 1.5-fold increased relative risk of ischaemic stroke. The risk of haemorrhagic stroke is not increased during use of HRT.
This relative risk is not dependent on age or duration of use, but as the baseline risk is strongly age-dependent, the overall risk of stroke in women who use HRT will increase with age (see section 4.4.)

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
a Study in women with no uterus
b No differentiation was made between ischaemic and haemorrhagic stroke
Both estradiol and dydrogesterone are substances with low toxicity. Symptoms such as nausea, vomiting, breast tenderness, dizziness abdominal pain, drowsiness/fatigue, and withdrawal bleeding could occur in cases of overdosing. It is unlikely that any specific or symptomatic treatment will be necessary.
Paediatric population
Aforementioned information is also applicable for overdosing in children.
