Package Leaflet: Information for the User
Estradot 37.5 micrograms/24 hours transdermal patch
Estradiol (as hemihydrate)
Read all of this leaflet carefully before you start using this medicine because it contains important information for you.
Contents of the pack and other information:
Estradot is a Hormone Replacement Therapy (HRT) that contains the female hormone estrogen.
Estradot is used in postmenopausal women who have been without a natural period for at least 12 months.
Estradot comes as a patch that you apply to your skin.
Estradot is used to:
Relieve symptoms of the menopause
During the menopause, the amount of estrogen produced by the body decreases. This can cause symptoms such as sudden feelings of heat in the face, neck, and chest (hot flashes). Estradot relieves these symptoms after the menopause. You will only be prescribed Estradot if your symptoms are seriously affecting your daily life.
Medical history and regular check-ups
The use of HRT carries risks that need to be considered when deciding whether to start or continue treatment.
Experience in treating women with premature menopause (due to ovarian failure or surgery) is limited. If you have premature menopause, the risks of using HRT may be different. Please consult your doctor.
Before starting (or restarting) HRT, your doctor will ask about your personal and family medical history. Your doctor may decide to perform a physical examination. This may include a breast examination and/or an internal examination, if necessary.
Once you have started treatment with Estradot, you should see your doctor for regular check-ups (at least once a year). During these check-ups, discuss the benefits and risks of continuing with Estradot with your doctor.
Have regular breast checks as recommended by your doctor.
Do not useEstradot
if any of the following applies to you. If you are not sure about any of the points below, consult your doctorbefore using Estradot.
Do not use Estradot:
If you experience any of the conditions mentioned above for the first time while using Estradot, stop treatment immediately and consult your doctor right away.
Warnings and precautions
Tell your doctor if you suffer from or have suffered from any of the following conditions before starting treatment, as they may come back or get worse during treatment with Estradot. In this case, you should see your doctor more often for regular check-ups:
Stop using Estradot and see a doctor immediately.
If you experience any of the following while using HRT:
For signs of a blood clot, see "Stop using Estradot and see a doctor immediately".
Note: Estradot is not a contraceptive. If you have been without a natural period for less than 12 months or are under 50 years old, you may still need to use additional contraceptive measures to prevent pregnancy. Talk to your doctor for advice.
HRT and cancer
Thickening of the lining of the womb (endometrial hyperplasia) and cancer of the lining of the womb (endometrial cancer)
Taking HRT with estrogen-only products will increase the risk of thickening of the lining of the womb (endometrial hyperplasia) and cancer of the lining of the womb (endometrial cancer).
Adding a progestogen to estrogen-only treatment for at least 12 days of each 28-day cycle will protect you from this extra risk. Therefore, your doctor will prescribe a progestogen separately if you still have your womb. If you have had a hysterectomy (removal of the womb), ask your doctor if you can be treated safely without a progestogen.
In women between the ages of 50 and 65 who still have their womb and are not taking HRT, about 5 in 1000 will be diagnosed with cancer of the lining of the womb.
In women between the ages of 50 and 65 who still have their womb and are taking HRT with estrogen-only products, between 10 and 60 in 1000 will be diagnosed with endometrial cancer (i.e., between 5 and 55 extra cases), depending on the dose and duration of therapy.
Unexpected bleeding
You will experience monthly bleeding (called withdrawal bleeding) while using Estradot in combination with a progestogen. However, if you experience any of the following, see your doctor as soon as possible:
Breast cancer
Evidence shows that using combined estrogen-progestogen or estrogen-only HRT increases the risk of breast cancer. The extra risk depends on how long you use HRT. The extra risk becomes apparent within a few years. However, it returns to normal within a few years (at most 10 years) after stopping HRT.
Comparison
In women between the ages of 50 and 54 who are not using HRT, about 13 to 17 in 1000 will be diagnosed with breast cancer over a 5-year period.
In women aged 50 who start estrogen-only HRT for 5 years, there will be between 16 and 17 cases per 1000 users (i.e., 0 to 3 extra cases).
In women aged 50 who start combined estrogen-progestogen HRT for 5 years, there will be about 21 cases per 1000 users (i.e., 4 to 8 extra cases).
In women between the ages of 50 and 59 who are not taking HRT, about 27 in 1000 will be diagnosed with breast cancer over a 10-year period.
In women aged 50 who start estrogen-only HRT for 10 years, there will be about 34 cases per 1000 users (i.e., 7 extra cases).
In women aged 50 who start combined estrogen-progestogen HRT for 10 years, there will be about 48 cases per 1000 users (i.e., 21 extra cases).
Additionally, you are recommended to participate in breast screening programs. During breast screening, it is important to inform the nurse or healthcare professional performing the X-ray that you are using HRT, as this medication may increase the density of your breasts, which can affect the results of the mammogram. When breast density increases, the mammogram may not detect all lumps.
Ovarian cancer
Ovarian cancer is much less common than breast cancer. Using HRT with estrogen-only or combined estrogen-progestogen products has been associated with a slightly increased risk of ovarian cancer.
The risk of ovarian cancer varies with age. For example, in women between the ages of 50 and 54 who are not using HRT, about 2 cases of ovarian cancer per 2000 women are diagnosed over a 5-year period. In women using HRT for 5 years, about 3 cases per 2000 users are diagnosed (i.e., about 1 extra case).
Effect of HRT on the heart and circulation
Blood clots in a vein (thrombosis)
The risk of blood clots in the veins is about 1.3 to 3 times higher for HRT users than for non-users, especially during the first year of treatment.
Blood clots can be serious and, if one travels to the lungs, can cause chest pain, difficulty breathing, fainting, or even death.
You are more likely to develop a blood clot in your veins as you get older and if you experience any of the following. Inform your doctor if any of the following apply to you:
For signs of a blood clot, see "Stop using Estradot and see a doctor immediately".
Comparison
In women in their 50s who are not taking HRT, about 4 to 7 in 1000 are expected to have a blood clot in a vein over a 5-year period.
In women in their 50s who take combined estrogen-progestogen HRT for 5 years, about 9 to 12 cases per 1000 users are expected (i.e., 5 extra cases).
In women in their 50s who have had a hysterectomy and are treated with estrogen-only HRT for 5 years, about 5 to 8 cases per 1000 users are expected (i.e., 1 extra case).
Heart disease (heart attack)
There is no evidence that HRT prevents heart attacks.
Women over 60 years old who use combined estrogen-progestogen HRT are slightly more likely to develop heart disease than those not using HRT.
In women who have had a hysterectomy and are using estrogen-only HRT, there is no increased risk of developing heart disease.
Stroke
The risk of having a stroke is about 1.5 times higher for women using HRT than for those not using HRT. The number of extra cases of stroke due to HRT will increase with age.
Comparison
In women in their 50s who are not taking HRT, about 8 in 1000 are likely to have a stroke over a 5-year period. In women in their 50s who are taking HRT, about 11 in 1000 are likely to have a stroke over a 5-year period (i.e., 3 extra cases).
Other conditions
Other medicines and Estradot
Some medicines may interfere with the effect of Estradot. This may cause irregular bleeding. This occurs with the following medicines:
HRT may affect the performance of other medicines:
Please inform your doctor or pharmacist if you are taking or have recently taken any other medicines, including those obtained without a prescription, herbal remedies, or other natural products. Your doctor will inform you about this.
Lab tests
If you need to have a blood test, tell your doctor or the laboratory staff that you are using Estradot, as this medicine may affect the results of some tests.
Pregnancy and breastfeeding
Estradot is a medicine for postmenopausal women only. If you become pregnant, stop using Estradot and contact your doctor.
Do not use Estradot if you are pregnant or breastfeeding.
Driving and using machines
Estradot has no known effects on the ability to drive or use machines.
Follow the administration instructions for this medication exactly as indicated by your doctor. Consult your doctor or pharmacist if you have any doubts.
Your doctor will try to prescribe the lowest dose to treat your symptom for the shortest possible time. Talk to your doctor if you think this dose is too strong or insufficient.
How long should you use Estradot
It is essential to use the lowest effective dose and only for as long as necessary.
Periodically, you should discuss the potential risks and benefits associated with using Estradot with your doctor and whether you still need this treatment.
When to start treatment
When to apply Estradot
Any adhesive that remains on the skin can be easily removed by rubbing. If this happens, place a new Estradot patch in a different area of the skin.
Women who have had their uterus removed
The Estradot patch should be applied continuously without interruption. There is no need to add another type of hormone called progestogen unless there is growth of the endometrium outside the uterus (endometriosis). Check the risks to consider with hormone replacement therapy in section 2, Warnings and precautions.
Women who still have their uterus
Your doctor will prescribe another hormone for you to take with Estradot, called progesterone, to reduce the risk of uterine cancer. If you apply Estradot continuously without interruption, the progesterone tablet should be taken for at least 12-14 days each month/28-day cycle. Check the risks to consider with hormone replacement therapy in section 2, Warnings and precautions.
You may experience irregular bleeding or spotting during the first few months of treatment. If you have heavy bleeding or the bleeding or spotting continues after a few months of treatment, talk to your doctor so that they can reevaluate your treatment if necessary (see section 2, Unexpected bleeding).
Where to apply Estradot
Apply the patch to the lower abdomen, below the waistline. Avoid the waistline, as clothing may cause the patch to peel off. Do not apply the patch to the breasts or near the breasts.
When changing the patch, according to your twice-weekly schedule, apply the new patch to a different area. Do not apply a new patch to the same area for at least one week.
Before applying Estradot, make sure your skin is:
How to apply Estradot
Each patch is individually sealed in a protective envelope. Open the envelope by the slit and remove the patch (do not use scissors to open the envelope as they may damage the patch). | |
A protective film covers the adhesive face of the patch. This film should be removed before applying the patch to the skin. Apply the patch immediately after opening the envelope and removing the protective film. Take the patch with the protective film facing you. Remove half of the protective film and discard it. Try to avoid touching the adhesive face of the patch with your fingers. | |
Take the other half of the protective film, apply the adhesive part of the patch to a dry area of the lower abdomen. Press the adhesive part against the skin to ensure it adheres correctly, especially at the edges. Remove the other part of the protective film. | |
Hold the straight edge of the protective film and peel it off the patch. | |
Press the adhesive part against the skin to ensure it adheres correctly. Press the patch firmly onto the skin with the palm of your hand for at least 10 seconds. | |
Make sure the patch has been placed correctly on the skin and run your fingers over the edges to check for good contact between the patch and the skin. | |
When changing the patch, peel it off, and fold it in half with the adhesive side inward. See section 5, "Storage of Estradot" for instructions on how to safely dispose of the patch. Do not throw used patches down the toilet.
Additional practical information
If the patch has been applied correctly, it should not affect bathing, swimming, showering, or exercising. If a patch comes off, for example during bathing or showering, move it to eliminate water. After drying and letting the skin cool, you can apply the same patch to a different area of the skin on the lower abdomen (see "Where to apply Estradot").
If the patch does not adhere completely to the skin, use a new patch. Regardless of the day it happens, change this patch on the same day according to the initial schedule.
When sunbathing or using a sunbed, you should cover the patch. When bathing, you can wear the patch under your swimsuit.
If you need surgery
If you are going to undergo surgery, tell your surgeon that you are using Estradot. You may need to stop using Estradot 4 to 6 weeks before the operation to reduce the risk of blood clots (see section 2, Blood clots in a vein). Ask your doctor when you can start Estradot treatment again.
If you use more Estradot than you should
If you have taken too much Estradot, you should remove the patch. The symptoms of overdose are usually breast pain and/or vaginal bleeding. Acute overdose is unlikely due to the route of administration of Estradot (the patch releases the medication gradually). If the symptoms persist, you should contact your doctor.
If you forget to use Estradot
If you forgot to change the patch, apply another patch as soon as you remember. Regardless of the day it happens, change the patch on the same days as in the initial schedule.
Do not take a double dose to make up for the forgotten application.
If you stop using Estradot
Stopping treatment with Estradot may increase the risk of irregular bleeding or spotting. Inform your doctor if this happens. After a prolonged period without treatment, you should consult your doctor before starting to use the patch again.
If you have any other questions about using this medication, ask your doctor or pharmacist.
