1. What is Estradot and what is it used for

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.

Prevention of osteoporosis

After the menopause, some women may develop fragile bones (osteoporosis). Talk to your doctor about all the available treatment options. If you are at high risk of getting fractures due to osteoporosis and other medicines are not suitable for you, you may use Estradot to prevent osteoporosis after the menopause.

2. What you need to know before you use Estradot

Medical history and regular check-ups

The use of HRT involves 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 talk to 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 start treatment with Estradot, you should see your doctor for regular check-ups (at least once a year). During these check-ups, talk to your doctor about the benefits and risks of continuing with Estradot.

Have regular breast checks as recommended by your doctor.

Do not use Estradot

if any of the following applies to you. If you are not sure about any of the points below, talk to your doctor before using Estradot.

Do not use Estradot:

• if you have or have had breast cancer, or if there is a suspicion that you may have it;
• if you have a cancer that is dependent on estrogen, such as cancer of the lining of the womb (endometrium), or if there is a suspicion that you may have it;
• if you have abnormal vaginal bleeding;
• if you have thickening of the lining of the womb(endometrial hyperplasia) for which you are not receiving treatment;
• if you have or have had a blood clot in a vein(thrombosis), such as in the legs (deep vein thrombosis) or lungs (pulmonary embolism);
• if you have a blood clotting disorder(such as deficiency of protein C, protein S, or antithrombin);
• if you have or have had a disease caused by blood clots in the arteries, such as a heart attack, stroke, or angina;
• if you have or have had a liver diseaseand your liver function tests have not returned to normal;
• if you have a rare blood disorder called porphyriathat is inherited from your parents;
• if you are allergic(hypersensitive) to estradiol or any of the other ingredients of this medicine (listed in section 6 Contents of the pack and other information);

If you experience any of the conditions mentioned above for the first time while using Estradot, stop the treatment immediately and consult your doctor right away.

Warnings and precautions

Tell your doctor if you have or have had 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:

• fibroids in the womb;
• growth of the lining of the womb outside the womb (endometriosis) or a history of thickening of the lining of the womb (endometrial hyperplasia);
• increased risk of developing blood clots (see "Blood clots in a vein (thrombosis)");
• increased risk of getting a cancer that is dependent on estrogen (such as when your mother, sister, or grandmother has had breast cancer);
• high blood pressure;
• liver disease, such as a benign tumor in the liver;
• diabetes;
• gallstones (cholelithiasis);
• migraine or severe headaches;
• a disease of the immune system that affects many parts of the body (systemic lupus erythematosus, SLE);
• epilepsy;
• asthma;
• a disease that affects the eardrum and ear (otosclerosis);
• a very high level of fat in your blood (triglycerides);
• fluid retention due to heart or kidney problems;
• hereditary and acquired angioedema.

Stop using Estradot and see a doctor immediately.

If you experience any of the following while using HRT:

• any of the conditions mentioned in the "Do not use Estradot" section
• yellowing of the skin or the whites of the eyes (jaundice). This may be a sign of liver disease
• swelling of the face, tongue, or throat, and difficulty swallowing or hives accompanied by difficulty breathing, which suggest angioedema;
• a significant increase in your blood pressure (symptoms may be headache, tiredness, dizziness)
• migraine-like headaches that occur 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 breathing.

For signs of a blood clot, see "Stop using Estradot and see a doctor immediately".

Note: Estradot is not a contraceptive. If it has been less than 12 months since your last period or you 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 only estrogen-containing 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 your estrogen 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 your womb removed (hysterectomy), ask your doctor whether you can be treated safely with this medicine without the use of 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 only estrogen, 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:

• bleeding or spotting that continues for more than the first 6 months;
• bleeding or spotting that starts after you have been using Estradot for more than 6 months;
• bleeding or spotting that continues after you have stopped using Estradot;

Breast cancer

Evidence shows that using combined estrogen-progestogen HRT 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 combined estrogen-progestogen HRT for 5 years, about 21 in 1000 users will be diagnosed with breast cancer (i.e., about 4-8 extra cases).

In women between the ages of 50 and 59 who are not using 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, about 34 in 1000 users will be diagnosed with breast cancer (i.e., about 7 extra cases).

In women aged 50 who start combined estrogen-progestogen HRT for 10 years, about 48 in 1000 users will be diagnosed with breast cancer (i.e., about 21 extra cases).

• Check your breasts regularly. See your doctor if you notice any changes, such as:

• grooves or dimples in the skin;
• changes in the nipples;
• any lump that you can see or feel.

In addition, you are recommended to participate in breast screening programs. When you have a mammogram, it is important to tell the nurse or healthcare professional who is taking the X-ray that you are using HRT, as this medicine may increase the density of your breasts, which can affect the outcome 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 therapy 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 in 2000 will be diagnosed with ovarian cancer over a 5-year period. In women using HRT for 5 years, about 3 in 2000 users will be diagnosed with ovarian cancer (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 get a blood clot in your veins if you:

• are unable to walk for a long time due to major surgery, injury, or illness (see also section 3, If you need to have surgery);
• are seriously overweight (BMI >30 kg/m2);
• have a blood clotting disorder that needs long-term treatment with a medicine used to prevent blood clots;
• have any of your close relatives who have had a blood clot in the leg, lung, or other organ;
• have systemic lupus erythematosus (SLE);
• have cancer.

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 will 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 in 1000 users will have a blood clot in a vein (i.e., about 5 extra cases).

In women in their 50s who have had their womb removed and have been treated with estrogen-only HRT for 5 years, about 5 to 8 in 1000 users will have a blood clot in a vein (i.e., about 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 who do not use HRT.

In women who have had their womb removed 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 women not using HRT. The number of extra stroke cases will increase with age.

Comparison

In women in their 50s who are not taking HRT, about 8 in 1000 will have a stroke over a 5-year period. In women in their 50s who are using HRT, about 11 in 1000 will have a stroke over a 5-year period (i.e., about 3 extra cases).

Other conditions

• HRT does not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start HRT after the age of 65. Talk to your doctor for advice.

Other medicines and Estradot

Some medicines may interfere with the effect of Estradot. This may cause irregular bleeding. This happens with the following medicines:

• Medicines for epilepsy (such as phenobarbital, phenytoin, and carbamazepine);
• Medicines for tuberculosis (such as rifampicin, rifabutin);
• Medicines for HIV infection (such as nevirapine, efavirenz, ritonavir, nelfinavir);
• Herbal remedies containing St. John's Wort (Hypericum perforatum);

HRT may affect the performance of other medicines:

• A medicine for epilepsy (lamotrigine), as it may increase the frequency of seizures.
• Other anti-infective medicines (such as ketoconazol, erythromycin).
• The combined hepatitis C virus (HCV) regimen ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin; glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir (see section 4.4) may cause elevations in liver function blood test results (increase in liver enzyme ALT) in women using CHC that contains ethinylestradiol. Estradot contains estradiol instead of ethinylestradiol. It is not known whether an increase in liver enzyme ALT can occur when using Estradot with this combined HCV regimen. Your doctor will inform you about this.

Please tell 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.

3. How to use Estradot

Follow your doctor's instructions for administering this medication exactly. Consult your doctor or pharmacist if you have any doubts.

Your doctor will try to prescribe you 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

• If you are not currently using any hormone replacement therapy (patches or tablets), or if you have been using a continuous combined hormone replacement therapy product (in which estrogen and progestogen are administered every day without interruption), you can start using Estradot on any day.
• If you are switching from a cyclic or sequential hormone replacement therapy (in which progestogen is added for 12-14 days of the cycle), you should start using Estradot the day after completing your previous regimen.

When to apply Estradot

• Each Estradot patch should be changed twice a week (every 3 to 4 days). It is best to always change it on the same two days of the week (e.g., Monday and Thursday). The Estradot package contains a calendar-control on the back that will help you remember your schedule. Mark the two-day-a-week schedule you want to follow. Always change the patch on the two days of the week you have marked.
• You should wear the Estradot patch continuously until it is time to change it for a new patch.

Any adhesive that remains on the skin can be easily removed by rubbing. If this happens, place a new Estradot patch on another 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-a-week 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:

• clean, dry, and cool,
• free of any dust, oil, cream, or lotion,
• free of cuts and/or irritations.

How to apply Estradot

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 as your 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 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 your 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.
