6. Contents of the pack and additional information

1. What is Estraderm Matrix and what is it used for

Estraderm Matrix is a Hormonal Replacement Therapy (HRT) that contains the female sex hormone estrogen.

Estraderm Matrix is used in postmenopausal women.

Estraderm Matrixis usedfor:

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, brief episodes of heat in the face, neck, and chest (hot flashes). Estraderm Matrix relieves these symptoms after menopause. Estraderm Matrix will only be prescribed if your symptoms seriously interfere with your daily life.

Prevention of osteoporosis

After menopause, some women may develop brittle bones (osteoporosis). Consult with your doctor about all available treatment options. If you have a high risk of suffering fractures due to osteoporosis and other medications are not suitable for you, you may use Estraderm Matrix to prevent osteoporosis after menopause.

2. What you need to know before starting to use Estraderm Matrix

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 Estraderm Matrix 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 Estraderm Matrix.

Perform regular breast checks, as recommended by your doctor.

fibroids inside the uterus
growth of the uterine lining outside the uterus (endometriosis) or history of excessive growth of the uterine lining (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 when your mother, sister, or grandmother has had breast cancer)
increased blood pressure
liver disease, such as a benign tumor in the liver
diabetes
gallstones
renal disorders
migraine or severe headaches
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
hypothyroidism (a condition that occurs due to abnormal functioning of the thyroid gland that produces insufficient hormone requiring treatment)
hereditary or acquired angioedema (a disease that can cause rapid swelling of the hands, feet, face, lips, eyes, tongue, throat, with blockage of the airway or digestive tract)

Stop using Estraderm Matrix 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 Estraderm Matrix”
yellowing of the skin or white of the eyes (jaundice). This may be a sign of liver disease
swelling of the face, tongue, and/or throat and/or difficulty swallowing or urticaria, along with difficulty breathing that suggests angioedema
significant increase in blood pressure (symptoms may include headache, fatigue, dizziness)
migraine-type 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:Estraderm Matrix 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

Thickening of the uterine lining (endometrial hyperplasia) and endometrial cancer

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

The addition of a progestin to estrogen treatment for at least 12 days of each 28-day cycle will protect against this additional risk. Therefore,if you still have your uterus, your doctor will prescribe a progestin separately for at least 12 days per cycle to reduce the risk of endometrial cancer. If you have had your uterus removed (hysterectomy), ask your doctor if you can be treated with this medication safely without using a progestin.

In women aged 50-65 years who still have their 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 uterus and on THS treatment with estrogen-only, 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.

Estraderm Matrix contains a higher dose of estrogens than other THS products that contain only estrogens. The risk of endometrial cancer when using Estraderm Matrix with a progestin is unknown.

Unexpected Bleeding

You will experience bleeding once a month (called menstrual bleeding) while using Estraderm Matrix.However, if you experience bleeding or spotting of blood that:

continues for more than the first 6 months
starts after you have been using Estraderm Matrix for more than 6 months
continues after you have stopped using Estraderm Matrix

See your doctor as soon as possible.

Breast Cancer

The available data show that the use of hormone replacement therapy (HRT) with estrogen-progestin or estrogen-only increases the risk of breast cancer. The additional risk depends on the duration of 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 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 taking HRT with estrogen-progestin 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 will be diagnosed over a 10-year period.

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

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

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

furrows or grooves in the skin
changes in the nipples
any lump that you can see or feel

Additionally, it is recommended that you join a mammography screening program when offered to you. For mammography screening, it is essential to inform the healthcare professional or nurse who directs the X-rays that you are using HRT, as this medication can increase the density of your breasts, which may affect the result of the mammography. When breast density increases, mammography may not detect all lumps.

Endometrial Cancer

Endometrial cancer occurs less frequently than breast cancer. The use of HRT with estrogen-only or estrogen-progestin has been associated with a slightly higher risk of endometrial cancer.

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

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 you are in any of the following situations:

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 overweight (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 Estraderm Matrix 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 will develop a blood clot in a vein over a 5-year period.

In women in their 50s who take HRT combined with estrogen-progestin for 5 years, there will be 9 to 12 cases per 1000 users (i.e., 5 additional cases).

In women in their 50s who have had their uterus removed and have been treated with HRT with estrogen-only 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 will prevent a heart attack.

Women over 60 years old who use HRT with estrogen and progestin are slightly more likely to develop heart disease than those who do not take any hormone replacement therapy.

In women who have had their uterus removed and are only on estrogen treatment, there is no increased risk of heart disease.

Stroke

The risk of stroke is approximately 1.5 times higher in HRT users than in non-users. The number of additional stroke cases due to HRT use increases with age.

Comparison

In women in their 50s who are not taking HRT, a mean of 8 out of 1000 will likely experience a stroke over a 5-year period.

In women in their 50s who are treated with HRT, 11 out of 1000 will likely experience 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.

Children

Estraderm Matrix should not be used in children.

Other Medications and Estraderm Matrix

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

medications forepilepsy(such as phenobarbital, phenytoin, carbamazepine);
medications fortuberculosis(such as rifampicin, rifabutin);
medications forHIV infection(such as nevirapine, efavirenz, ritonavir, nelfinavir);
preparations based on medicinal plants that containSt. John's Wort(Hypericum perforatum).

HRT may affect how other medications work:

medications for epilepsy (lamotrigine), as the frequency of seizures may increase.
medications forhepatitis C virus (HCV)(such as a regimen of ombitasvir / paritaprevir / ritonavir with or without dasabuvir, as well as a regimen with glecaprevir / pibrentasvir) that may cause increases in liver function test results (elevated ALT levels) in women using combined hormonal contraceptives (CHCs) that contain ethinylestradiol. Estraderm Matrix contains estradiol instead of ethinylestradiol. It is not known if an increase in ALT levels can occur when using Estraderm Matrix with HCV combination regimens.
other anti-infective medications (such as ketoconazole, erythromycin)

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

Laboratory Tests

If you need a blood test, inform your doctor or laboratory staff that you are using Estraderm Matrix, as this medication may affect the results of some tests.Some laboratory tests, such as the glucose tolerance test or thyroid function test, may be affected by Estraderm Matrix treatment.

Pregnancy and Breastfeeding

Estraderm Matrix is a medication only for postmenopausal women. If you become pregnant, stop treatment with Estraderm Matrix and contact your doctor.

Estraderm Matrix should not be used during breastfeeding.

Driving and Operating Machinery

Estraderm Matrix does not affect the ability to drive or operate machinery.

3. How to Use Estraderm Matrix

Follow exactly the administration instructions of this medication as indicated by your doctor. In case of doubt, consult your doctor again.

Remember to apply Estraderm Matrix.

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 that this dose is too strong or insufficient.

Estraderm Matrix will be applied twice a week, that is, the patch should be changed every 3 or 4 days.

Estraderm Matrix can be administered both continuously and cyclically:

Continuous administration: uninterrupted application, using 2 patches per week.
Cyclic administration: 3-week treatment (2 patches per week) followed by a week without medication.

Your doctor will indicate which treatment schedule is most suitable for you.

If you have not had your uterus removed (hysterectomy), your doctor will probably prescribe tablets containing another hormone, progesterone, for you to take regularly for a certain period of time each month. Your doctor will explain how to take these tablets. After finishing the progesterone tablets each month, you may experience vaginal bleeding.

Follow the instructions given by your doctor on how to use the patches. If you estimate that the action of Estraderm Matrix is too strong or weak, inform your doctor or pharmacist.

HOW TO APPLY ESTRADERM MATRIX

You should wear the patch at all times. Change it every 3 or 4 days.

Each patch is sealed in a protective envelope and contains the active substance in an adhesive layer that adheres directly to the skin. This adhesive layer is covered by a transparent and larger-sized sheet, divided into two parts by a groove. The transparent sheet (removable sheet) will be removed before applying the patch.

Open the envelope by the notch (do not use scissors to avoid damaging the patch) and remove the patch (Fig. 1).

Make sure you do not have the previous patch before applying the new patch.

Fig. 1

Remove the patch from the envelope, remove the smaller part of the removable sheet first, then the larger one and dispose of them. Be careful not to touch the adhesive (Fig. 2, 3) and remember that the patch should not be folded so that the adhesive faces do not come into contact. (Fig. 2 and 3).

Figs. 2-3

Apply the patch immediately to an area below the waist (abdomen, buttocks, or lower back) and press it for 10-20 seconds (Fig. 4). Make sure it sticks well, especially at the edges. Do not check the patch's adhesion by pulling it once it is applied.

(Fig. 4).

Fig. 4

Choose an area where few wrinkles form due to movement and little friction with clothing, otherwise the patch will come off. The skin of the selected area should be dry and free of grease (since if not the patch will not stick), therefore do not use creams, lotions, or other cosmetics on the area where the patch is applied; also avoid areas with excessive hair and skin alterations or irritation.

Experience indicates that skin irritation is less in the buttocks. Therefore, whenever possible, Estraderm Matrix will be applied to this area.Do not place the Estraderm Matrix patch on the breasts.

As long as the patch has been applied correctly, you can take a shower, bathe, swim, or exercise. If the patch comes off after a bath or shower, apply a new patch when the skin is cold and dry. Do not apply the patch to greasy skin or after a hot bath or shower.

The selected area should be covered with clothing since it should not be exposed to direct sunlight or artificial light.

You should change the patch every 3 or 4 days to ensure that your body receives the necessary dose of estradiol regularly. To do this, it is simplest to change it on the same two days of the week, for example, Monday and Thursday. Choose two days that you can easily remember. To remember them, you will find a strip of labels in the box; stick the label with the selected days to the inside of the box's flap. Dispose of the rest of the labels.

Do not place the patch twice in a row in the same place.You can apply a new patch to a previously used area after a week. As long as you strictly follow these instructions, you will not have any problems wearing the patches for 3-4 days.

If the patch comes off, you can place the same patch on a different area of the skin. Make sure it is clean, dry, and free of creams or lotions. If the patch does not stick correctly to the skin, use a new one. It does not matter on which day this happens, go back to changing the patch on the same days as initially planned.

Once the patch has been used, remove it, fold it with the adhesive facing inward, and dispose of it, making sure it is out of reach of children.

Your doctor will indicate the duration of your treatment with Estraderm Matrix. Do not stop treatment without consulting your doctor first.

Estraderm Matrix should be used for as long as necessary, usually for several months or more. This will help control your symptoms and prevent bone loss that appears after menopause.

If you need surgery

If you are undergoing surgery, inform your surgeon that you are using Estraderm Matrix. You may need to stop using Estraderm Matrix between 4 and 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 treatment with Estraderm Matrix again.

If you use more Estraderm Matrix than you should

If you use more Estraderm Matrix than you should, contact your doctor or pharmacist immediately. Given the administration method, it is unlikely that you will experience an overdose with this medication.

In case of overdose or accidental ingestion, consult your doctor or pharmacist or call the Toxicological Information Service. Phone 915 620 420, indicating the medication and the amount used.

If you forgot to use Estraderm Matrix

If you forget to change the patch, apply a new one as soon as you remember. It does not matter on which day this happens, go back to changing the patch on the same days as initially planned.

If you have any other questions about the use of this product, ask your doctor or pharmacist.
