CLINORETTE is a brand name for Estradiol (also known as Oestradiol). The medicine, its uses, side effects and dosage are the same regardless of brand.
Used for: Hormone replacement therapy (HRT) for oestrogen deficiency symptoms in peri- and post-menopausal women with an intact uterus.
Verbatim from this product's MHRA label. Tap a section to expand.
Clinorette is continuous sequential HRT product. The calendar pack consists of 28 tablets. The 16 white tablets contain 2 mg of 17-β oestradiol and the 12 pink tablets contain 2 mg of 17-β oestradiol and 1 mg of norethisterone. One tablet is taken each day; a treatment cycle consists of 28 days.
A menstrual type vaginal bleed usually occurs at the end of the treatment cycle or after administration of the last pink, norethisterone containing, tablet. Unless there is a previous diagnosis of endometriosis, it is not recommended to add a progestagen in hysterectomised women.
4) should be used. Starting Clinorette Menstruating women take the first tablet on the fifth day of menstrual bleeding. If menstruation has stopped, or is infrequent or sporadic, the first tablet can be taken at any time. Patients changing from a cyclic or continuous sequential preparation should complete the cycle and then start Clinorette without a break in therapy.
Patients changing from a continuous combined preparation may start therapy at any time if amenorrhoea is established, or otherwise start on the first day of bleeding. Missed doses If a dose is forgotten the patient should be advised to take it as soon as they remember.
However, if a whole day has passed, patients should be advised not to take the missed tablet but to continue to take one tablet daily. A missed dose may increase the likelihood of break-through bleeding and spotting.

Breast cancer risk • An up to 2-fold increased risk of having breast cancer diagnosed is reported in women taking combined oestrogen-progestagen therapy for more than 5 years. • Any increased risk in users of oestrogen-only therapy is substantially lower than that seen in users of oestrogen-progestagen combinations.
4). • Results of the largest randomised placebo-controlled trial (WHI-study) and largest epidemiological study (MWS) are presented. 7 6 (5-7) #Overall risk ratio. The risk ratio is not constant but will increase with increasing duration on use.
Note:
Since the background incidence of breast cancer differs by EU country, the number of additional cases of breast cancer will also change proportionately. 5) +4 (0-9) #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.
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.
Medical examination/follow-up Before initiating or reinstituting HRT, a complete personal and family medical history should be taken. 4) 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 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. g. 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.
Reasons for immediate withdrawal of therapy Therapy should be discontinued when a contra-indication 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.
8). The addition of a progestogen for at least 12 days per cycle in non-hysterectomised women greatly reduces this risk. 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.
g. g. angina, myocardial infarction); Acute liver disease, or a history of liver disease as long as liver function tests have failed to return to normal; Known hypersensitivity to the active substances or to any of the excipients; Porphyria;

*WHI study in women with no uterus, which did not show an increase in risk of breast cancer 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.
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 progestagen to oestrogen-only therapy for at least 12 days per cycle can prevent this increased risk. 2)). Ovarian cancer Long-term use of oestrogen-only and combined oestrogen-progestagen HRT has been associated with a slightly increased risk of ovarian cancer.
In the Million Women Study 5 years of HRT resulted in 1 extra case per 2500 users. e. deep vein thrombosis or pulmonary embolism. 4). 4). 5 fold increased relative risk of ischaemic stroke. The risk of haemorrhagic stroke is not increased during use of HRT.
4. 6) 3 (1-5) *No differentiation was made between ischaemic and haemorrhagic stroke Other adverse reactions have been reported in association with oestrogen/progestagen treatment: – Gall bladder disease – Skin and subcutaneous disorders: chloasma, erythema multiforme, erythema nodosum, vascular purpura.
4)
8). For all HRT, an excess risk becomes apparent within a few years of use and increases with duration of intake but returns to baseline within a few (at most five) years after stopping treatment. In the MWS, the relative risk of breast cancer with conjugated equine oestrogens (CEE) or oestradiol (E2) was greater when a progestogen was added, either sequentially or continuously, and regardless of type of progestogen.
There was no evidence of a difference in risk between the different routes of administration. In the WHI study, the continuous combined conjugated equine oestrogen and medroxyprogesterone acetate (CEE + MPA) product used was associated with breast cancers that were slightly larger in size and more frequently had local lymph node metastases compared to placebo.
HRT, especially oestrogen-progestogen combined treatment, increases the density of mammographic images which may adversely affect the radiological detection of breast cancer. e. deep vein thrombosis or pulmonary embolism. One randomised controlled trial and epidemiological studies found a two to threefold higher risk for users compared with non-users.
For non-users, it is estimated that the number of cases of VTE that will occur over a 5 year period is about 3 per 1000 women aged 50-59 years and 8 per 1000 women aged between 60-69 years. It is estimated that in healthy women who use HRT for 5 years, the number of additional cases of VTE over a 5 year period will be between 2 and 6 (best estimate = 4) per 1000 women aged 50-59 years and between 5 and 15 (best estimate = 9) per 1000 women aged 60-69 years.
The occurrence of such an event is more likely in the first year of HRT than later. Generally recognised risk factors for VTE include a personal history or family history, severe obesity (Body Mass Index > 30 kg/m2) and systemic lupus erythematosus (SLE).
There is no consensus about the role of varicose veins in VTE. Patients with a history of VTE or known thrombophilic states have an increased risk of VTE. HRT may add to this risk. Personal or strong family history of thromboembolism or recurrent spontaneous abortion should be investigated in order to exclude a thrombophilic predisposition.
Until a thorough evaluation of thrombophilic factors has been made or anticoagulant treatment initiated, use of HRT in such patients should be viewed as contraindicated. Those women already on anticoagulant treatment require careful consideration of the benefit-risk of use of HRT.
The risk of VTE may be temporarily increased with prolonged immobilisation, major trauma or major surgery. As in all post-operative patients, scrupulous attention should be given to prophylactic measures to prevent VTE following surgery.
Where prolonged immobilisation is liable to follow elective surgery, particularly […]
