Prevention of postmenopausal osteoporosis:
Estradot is available in three strengths: 50, 75 and 100. Treatment must be initiated with an Estradot 50 microgram/24 hours patch. Adjustments can be made by using Estradot 50, 75 and 100 microgram patches. General instructions Estradot is administered as continuous therapy (uninterrupted application twice weekly).
In women with an intact uterus, Estradot should be combined with a progestagen approved for addition to oestrogen treatment in a continuous sequential dosing scheme: the oestrogen is dosed continuously. The progestagen is added for at least 12 to 14 days of every 28-day cycle, in a sequential manner.
Unless there is a previous diagnosis of endometriosis, it is not recommended to add a progestagen in hysterectomised women. In women who are not taking HRT or women transferring from a continuous combined HRT product, treatment may be started on any convenient day.
In women transferring from a sequential HRT regimen, treatment should begin the day following completion of the prior regimen. Method of administration The adhesive side of Estradot should be placed on a clean, dry area of the abdomen.
Estradot should not be applied to the breasts. Estradot should be replaced twice weekly. The site of application must be rotated, with an interval of at least 1 week allowed between applications to a particular site. The area selected should not be oily, damaged, or irritated.
The waistline should be avoided, since tight clothing may dislodge the patch. The patch should be applied immediately after opening the sachet and removing the protective liner. The patch should be pressed firmly in place with the palm of the hand for about 10 seconds, making sure there is good contact, especially around the edges.
In the event that a patch should fall off, the same patch may be reapplied. If necessary, a new patch may be applied. In either case, the original treatment schedule should be continued. The patch may be worn during bathing. If a woman has forgotten to apply a patch, she should apply a new patch as soon as possible.
6%). The erythema was observed after removing the patch by peeling from the skin at the application site. Mild pruritus and rash were also reported around the application site. Adverse drug reactions (Table 1) are ranked under headings of frequency, the most frequent first, using the following convention: very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data).
Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

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.
5 are not indicated for osteoporosis. 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 reinstituting 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).

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. • The increased risk in users of oestrogen-only therapy is lower than that seen in users of oestrogen-progestagen combinations.
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. 0 * Taken from baseline incidence rates in England in 2015 in women with BMI 27 (kg/m2).
Note:
Since the background incidence of breast cancer differs by EU country, the number of additional cases of breast cancer will also change proportionately. 8 * Taken from baseline incidence rates in England in 2015 in women with BMI 27 (kg/m2).

* 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 1,000 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 1,000 women between the ages of 50 and 65.
Adding a progestagen to […]
8). After stopping treatment risk may remain elevated for at least 10 years. The addition of a progestagen cyclically for at least 12 days per month/28 day cycle or continuous combined oestrogen-progestagen therapy in non- hysterectomised women prevents the excess risk associated with oestrogen-only HRT.
For Estradot 75 or 100 μg/day the endometrial safety of added progestagens has not been studied. 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.
Unopposed oestrogen stimulation may lead to premalignant or malignant transformation in the residual foci of endometriosis. Therefore, the addition of progestagens to oestrogen replacement therapy should be considered in women who have undergone hysterectomy because of endometriosis, if they are known to have residual endometriosis.
Breast cancer The overall evidence shows an increased risk of breast cancer in women taking combined oestrogen-progestagen or oestrogen-only HRT, that is dependent on the duration of taking HRT. 8). Oestrogen-only therapy • The WHI trial found no increase in the risk of breast cancer in hysterectomised women using oestrogen-only HRT.
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-progestagen 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-progestagen HRT, which becomes apparent within 5 years of use and diminishes over time after stopping.
