6.Contents of the package and additional information

Estradot is a Hormone Replacement Therapy (HRT) that contains the female sex hormone estrogen.

Estradot is used in postmenopausal women when at least 12 months have passed since their last natural menstrual period.

Estradot is presented as a patch that is applied to the skin.

Estradot is used for:

Relief of symptoms that appear during menopause

During menopause, the amount of estrogens produced by the woman's body decreases. This can cause symptoms such as sudden, intense heat waves in the face, neck, and chest (hot flashes). Estradot relieves these symptoms after menopause. Estradot will only be prescribed if your symptoms seriously interfere with your daily life.

Medical History and Regular Reviews

The use of THS involves risks that should be considered when deciding to use it or continue treatment.

The experience in treating women with premature menopause (due to ovarian failure or surgery) is limited. If you have premature menopause, the risks of using THS may be different. Please consult your doctor.

Before starting (or resuming) THS, 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 started on Estradot treatment, you should visit your doctor for regular reviews (at least once a year). In these reviews, discuss with your doctor the benefits and risks of continuing with Estradot.

Perform regular breast checks, as recommended by your doctor.

Do Not Use

if any of the following apply to you. If you are unsure about any of the points described below, consult your doctor before using Estradot.

Do not use Estradot:

• if you have or have hadbreast cancer, or if there is suspicion that you may have it;
• if you have acancer that depends on estrogen, such as endometrial cancer, or if there is suspicion that you may have it;
• if you haveabnormal vaginal bleeding;
• if you have anexcessive thickening of the uterine wall.(endometrial hyperplasia) for which you are not receiving treatment;
• if you have or have had the formation of ablood clot in a vein(thrombosis), such as in the legs (deep vein thrombosis) or in the lungs (pulmonary embolism);
• if you have ablood clotting disorder(such as protein C deficiency, protein S deficiency, or antithrombin deficiency);
• if you have or have had a disease caused by blood clots in the arteries, such as aheart attack, astroke, or aangina;
• if you have or have had aliver diseaseand your liver function tests have not normalized;
• if you have a rare blood disease calledporphyriathat is inherited;
• if you areallergic(hypersensitive) to estradiol, or to any of the other components of this medication (including those listed in section 6 Container and additional information);

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

Warnings and Precautions

Inform your doctor if you have or have had any of the following situationsbefore starting treatment, as they may recur or worsen during Estradot treatment. In that case, you should visit your doctor more frequently for regular reviews:

• fibroids within the uterus;
• growth of the uterine wall outside the uterus (endometriosis) or history of excessive growth of the uterine wall(endometrial hyperplasia);
• increased risk of developing blood clots(see “Blood clots in a vein (thrombosis)”;
• increased risk of developing a cancer that depends on estrogen (such as breast cancer);
• increased blood pressure;
• liver disease, such as a benign tumor in the liver;
• diabetes;
• gallstones (biliary calculi);
• severe headaches or migraines;
• a disease of the immune system that affects multiple organs of the body (systemic lupus erythematosus, SLE);
• epilepsy;
• asthma;
• a disease that affects the eardrum and ear (otosclerosis);
• very high levels 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 situations while using THS:

• any of the conditions mentioned in the section ‘Do Not Use Estradot’
• yellowing of the skin or whites of the eyes (jaundice). This may be a sign of liver disease
• swelling of the face, tongue, or throat and difficulty swallowing or urticaria accompanied by difficulty breathing, which suggests angioedema;
• significant increase in blood pressure (symptoms may include headache, fatigue, 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 and swollen legs;
  • sudden chest pain;
  • difficulty breathing.

For more information, see “Blood clots in a vein (thrombosis).”

Note: Estradot is not a contraceptive. If you have had less than 12 months since your last menstruation or are less than 50 years old, you may still need additional contraceptive measures to prevent pregnancy. Consult your doctor for advice.

THS and Cancer

Uterine Wall Thickening (Endometrial Hyperplasia) and Uterine Cancer (Endometrial Cancer)

The use of THS with estrogen-only products will increase the risk of developing uterine wall thickening (endometrial hyperplasia) and uterine cancer (endometrial cancer).

The addition of a progestogen to estrogen treatment for at least 12 days of each 28-day cycle will protect you from this additional risk. Therefore, your doctor will prescribe a progestogen separately if you still have a uterus. If you have had a hysterectomy, ask your doctor if you can be treated with this medication safely without using a progestogen.

In women aged 50-65 years who still have a uterus and are not being treated with THS, a mean of 5 out of 1000 will be diagnosed with endometrial cancer.

In the case of women aged 50-65 years with a uterus and on THS treatment with estrogen-only products, between 10 and 60 women out of 1000 will be diagnosed with endometrial cancer (i.e., between 5 and 55 additional cases), depending on the dose and duration of therapy.

Unexpected Bleeding

You will experience bleeding once a month (known as menstruation) while using Estradot in combination with a progestogen. However, if you experience unexpected bleeding or spotting, other than your monthly bleeding, that:

see your doctor as soon as possible.

Breast Cancer

The evidence shows that the use of hormone replacement therapy (HRT) with a combination of estrogen-progestogen or estrogen-only products increases the risk of breast cancer. The additional risk depends on the duration of HRT use. The additional risk becomes apparent after 3 years of use. After stopping HRT, the additional risk will decrease over time, but the risk may persist for 10 years or more if you have used HRT for more than 5 years.

Comparison

In women aged 50-54 years who are not using HRT, a mean of 13 to 17 out of 1000 will be diagnosed with breast cancer over a 5-year period.

In women aged 50 years who start HRT with estrogen-only products for 5 years, there will be between 16 and 17 cases per 1000 users (i.e., between 0 and 3 additional cases).

In women aged 50 years who start HRT with a combination of estrogen-progestogen for 5 years, there will be 21 cases per 1000 users (i.e., between 4 and 8 additional cases).

In women aged 50-59 years who are not taking HRT, a mean of 27 cases of breast cancer per 1000 women can be expected over a 10-year period.

In women aged 50 years who start HRT with estrogen-only products for 10 years, there will be 34 cases per 1000 users (i.e., 7 additional cases).

In women aged 50 years who start HRT with a combination of estrogen-progestogen for 10 years, there will be 48 cases per 1000 users (i.e., 21 additional cases).

• Examine your breasts regularly. See your doctor if you notice any changes, such as:
• skin creases or folds;
• changes in the nipples;
• any lump that you can see or feel.

Additionally, you are recommended to participate in screening mammography programs. When undergoing mammography screening, inform the nurse or healthcare professional performing the X-rays that you are using HRT, as this medication may increase the density of your breasts, which may affect the mammography results. When breast density increases, mammography may not detect all lumps.

Ovarian Cancer

Ovarian cancer occurs less frequently than breast cancer. The use of HRT with estrogen-only products or a combination of estrogen-progestogen has been associated with a slightly higher risk of ovarian cancer.

The risk of ovarian cancer varies with age. For example, in women aged 50-54 years who are not taking HRT, approximately 2 cases of ovarian cancer per 2000 women can be expected over a 5-year period. In women on HRT for 5 years, approximately 3 cases per 2000 patients (i.e., approximately 1 additional case) can be expected.

Effect of HRT on the Heart and Circulation

Blood Clots in a Vein (Thrombosis)

The risk ofblood clots in veinsis approximately 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 dislodges and travels to the lungs, it can cause chest pain, difficulty breathing, fainting, or even death.

You are more likely to develop a blood clot in your veins with age and if you experience any of the following situations. Inform your doctor if any of the following situations occur to you:

• you are unable to walk for a prolonged period due to major surgery, injury, or illness (see also section 3, If you need surgery);
• you have significant obesity (BMI>30 kg/m2);
• you have a blood clotting disorder that requires long-term treatment with a medication used to prevent blood clots;
• if any of your close relatives have had a blood clot in a vein, lung, or other organ;
• if you have systemic lupus erythematosus (SLE);
• if you 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, a mean of 4 to 7 out of 1000 can be expected to have a blood clot in a vein over a 5-year period.

In women in their 50s who are taking HRT with a combination of estrogen-progestogen for 5 years, there will be 9 to 12 cases per 1000 users (i.e., 5 additional cases).

In women who have had their uterus removed and have been treated with HRT with estrogen-only products for 5 years, there will be 5 to 8 cases per 1000 users (i.e., 1 additional case).

Heart Disease (Heart Attack)

There is no evidence that HRT prevents heart attacks.

Women over 60 years old who are taking HRT with a combination of estrogen-progestogen have a slightly higher risk of developing heart disease than non-users.

In the case of women who have had their uterus removed and are being treated with HRT with estrogen-only products, there is no increase in the risk of developing heart disease.

Stroke

The risk of stroke is approximately 1.5 times higher for women treated with HRT than for non-users. The number of additional stroke cases due to HRT use will increase with age.

Comparison

In women in their 50s who are not taking HRT, a mean of 8 out of 1000 can be expected to have a stroke over a 5-year period. In women in their 50s who are being treated with HRT, 11 out of 1000 can be expected to have a stroke over a 5-year period (i.e., 3 additional 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. Consult your doctor for advice.

Other Medications and Estradot

Some medications may interfere with the effect of Estradot. This may cause irregular bleeding. This occurs with the following medications:

-Medications forepilepsy(such as phenobarbital, phenytoin, and carbamazepine);

-Medications fortuberculosis(such as rifampicin, rifabutin);

-Medications forinfection with HIV(such as nevirapine, efavirenz, ritonavir, nelfinavir);

-Preparations based on medicinal plants containingSt. John's Wort(Hypericum perforatum);

HRT may affect the functioning of other medications:

-A medication for epilepsy (lamotrigine), which may increase the frequency of seizures.

-Otherantibiotics(such as ketoconazole, erythromycin).

-Medications for hepatitis C virus (HCV) (e.g., combination regimen for HCV ombitasvir/paritaprevir/ritonavir with or without dasabuvir or glecaprevir/pibrentasvir) may cause elevated liver function test results (increased ALT levels) in women using HCV with ethinylestradiol. Estradot contains estradiol instead of ethinylestradiol. It is unknown whether an increase in ALT levels can occur when using Estradot with this HCV combination regimen.

Please inform your doctor or pharmacist if you are taking or have recently taken other medications, including those purchased without a prescription, herbal remedies, or other natural products. Your doctor will advise you accordingly.

Laboratory Tests

If you need a blood test, inform your doctor or laboratory staff that you are using Estradot, as this medication may affect the results of some tests.

Pregnancy and Breastfeeding

Estradot is a medication only for postmenopausal women. If you become pregnant, stop using Estradot and contact your doctor.

Do not useEstradotif you are pregnant or breastfeeding.

Driving and Operating Machinery

Estradot has no known effects on driving or operating machinery.

Follow exactly the administration instructions of this medication 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 period of time possible. Talk to your doctor if you consider this dose too strong or insufficient.

How long should you use Estradot

It is essential to use the lowest effective dose and only as long as necessary.

You should periodically discuss with your doctor the possible risks and benefits associated with the use of Estradot and if you still need this treatment.

When to start treatment

-If you are not currently using any hormone replacement therapy (patches or tablets), orif you have been using a continuous combined hormone replacement therapy product (in which estrogen and progesterone are administered daily without interruption), you can start using Estradot on any day.

-If you are switching from a cyclic or sequential hormone replacement therapy (in which progesterone is added for 12-14 days of the cycle), you must start using Estradot the day after completing your previous regimen.

When to apply Estradot

-Each Estradot patch must be changed twice a week (every3 to4 days). It is best to change it always on the same two days of the week (for example, Monday and Thursday). The Estradot packaging contains a calendar-control on the back that will help you remember your schedule. Mark the two-day schedule you want to follow. Change the patch always on the two days of the week you have marked.

-You should wear the Estradot patch continuously until you change it for a new patch.

Any adhesive that remains on the skin can be easily removed by friction. If this occurs, place a new Estradot patch on a different area of the skin.

Women who have had a hysterectomy

The Estradot patch should be applied continuously without interruption. Progesterone is not necessary unless there is endometrial growth outside the uterus (endometriosis). Check the risks to consider with hormone replacement therapy in section 2, Warnings and Precautions.

Women who still have a 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 every month/cycle of 28 days. 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 bleeding or spotting continues after a few months of treatment, talk to your doctor to reevaluate your treatment if necessary (see section 2, Unexpected Bleeding).

Where to apply Estradot

Apply the patch to the lower abdomen, below the waist. Avoid the waist, 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 two-day schedule, apply the new patch to a different area. Do not apply a new patch to the same area for at least a week.

Before applying Estradot, make sure your skin is:

-clean, dry, and fresh,

-free of any powder, 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 sticky side inwards,See section 5, "Storage of Estradot" for instructions on how to safely dispose of the used patch. Do not throw the used patches in the toilet.

Additional practical information

If the patch has been applied correctly, it should not affect your bath, swimming, shower, or exercise. If a patch peels off, for example, during a bath or shower, move it to remove the water. After drying and allowing the skin to 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. It does not matter on which day this occurs, change this patch on the same day according to the initial schedule.

When taking the sun or using a solarium, you should cover the patch. When bathing, you can wear the patch under your swimsuit.

If you need surgery

If you are undergoing surgery, inform your surgeon that you are using Estradot. You may need to stop using Estradot for 4-6 weeks before the operation to reduce the risk of blood clot formation (see section 2, Blood Clots in a Vein). Ask your doctor when you can start using Estradot again.

If you use moreEstradotthan you should

If you have taken too muchEstradot, remove the patch. The symptoms of overdose are usually breast pain and/or vaginal bleeding.Acute overdose is unlikely due to the administration route ofEstradot(the patch releases the drug gradually). If symptoms persist, contact your doctor.

If you forget to useEstradot

If you forget to change the patch, apply a new patch as soon as you remember. It does not matter on which day this occurs, change the patch on the same days as the initial schedule.

Do not take a double dose to compensate for the missed application.

If you interrupt treatment withEstradot

Stopping treatment withEstradotmay increase the risk of irregular bleeding or spotting. Inform your doctor if this occurs. 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 the use of this medication, ask your doctor or pharmacist.
