Contents of the Package Leaflet
Estradiol Meriestra is a hormone replacement therapy (HRT) that contains the female hormone estrogen.
Estradiol Meriestra is used for:
Relief of symptoms that occur after menopause.
Menopause occurs naturally in all women, usually between the ages of 45 and 55. It also occurs in younger women who have had their ovaries removed. During menopause, the amount of estrogen produced by the woman's body decreases sharply. This can result in symptoms such as a feeling of heat in the face, neck, and chest ("hot flashes"). Estradiol Meriestra relieves these symptoms after menopause. Your doctor will only prescribe Estradiol Meriestra if the symptoms you are experiencing severely affect your daily life.
Estradiol Meriestra only contains estrogen, which is specifically indicated for women without a uterus who do not need to take progestogens as well. If you have not had a hysterectomy, you should also take progestogens with Estradiol Meriestra, following your doctor's instructions.
Prevention of osteoporosis
After menopause, some women develop weakness in the bones (osteoporosis). You should discuss all available options with your doctor.
If you are at increased risk of fractures due to osteoporosis and other medications are not suitable for you, you can take Estradiol Meriestra to prevent osteoporosis after menopause.
There is limited experience in treating women over 65 years of age with Estradiol Meriestra.
Medical history and periodic reviews
The use of Hormone Replacement Therapy (HRT) involves a series of risks that must be weighed when deciding whether to take it or continue taking it.
Experience in treating women with premature menopause (due to ovarian failure or removal) is limited. If you have premature menopause, the risks of using HRT may be different. Consult your doctor.
Before starting (or restarting) HRT, your doctor will ask you questions about your medical history and that of your family. Your doctor may need to perform a medical examination that may include a breast examination and/or an internal examination, if necessary.
Once you have started taking Estradiol Meriestra, you should undergo regular medical check-ups (at least once a year). During these check-ups, discuss the benefits and risks of continuing Estradiol Meriestra treatment with your doctor.
Undergo frequent mammograms, as determined by your doctor.
Do not take Estradiol Meriestra
If you have any of the following conditions. If you are unsure about any of the following points, consult your doctorbefore taking Estradiol Meriestra.
Do not take Estradiol Meriestra
If any of these situations occur for the first time while you are taking Estradiol Meriestra, stop taking the medication and consult your doctor immediately.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Estradiol Meriestra.
Before starting treatment, inform your doctor if you have ever had any of the following problems, as they may recur or worsen during treatment with Estradiol Meriestra. If that happens, you should visit your doctor more frequently for check-ups:
Stop taking Estradiol Meriestra and visit your doctor immediately.
If you experience any of these events while taking HRT:
For more information, see "Blood clots in a vein (thrombosis)".
Note:Estradiol Meriestra 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 an additional contraceptive method to avoid becoming pregnant. Ask your doctor for advice.
HRT and cancer
Excessive thickening of the uterine lining (endometrial hyperplasia) and cancer of the uterine lining (endometrial cancer)
Taking HRT with only estrogens increases the risk of excessive thickening of the uterine lining (endometrial hyperplasia) and cancer of the uterine lining (endometrial cancer).
Taking progestogens in addition to estrogens for at least 12 days every 28-day cycle helps protect against this additional risk. Therefore, if you have a uterus, your doctor will also prescribe progestogens. If you have had a hysterectomy (removal of the uterus), consult your doctor to see if you can take this medication without progestogens.
In women with a uterus who are not taking HRT, on average, 5 out of 1,000 will be diagnosed with endometrial cancer between the ages of 50 and 65.
In women between the ages of 50 and 65 who have a uterus and take HRT that contains only estrogens, between 10 and 60 women out of 1,000 will be diagnosed with endometrial cancer (i.e., between 5 and 55 additional cases), depending on the dose and duration of treatment.
Unexpected bleeding
You will experience bleeding once a month (also called withdrawal bleeding) while taking Estradiol Meriestra. However, if you have unexpected bleeding or spotting outside of your monthly bleeding that:
see your doctor as soon as possible
Breast cancer
Existing data show that the use of Hormone Replacement Therapy (HRT) with combined estrogen-progestogen or only estrogen increases the risk of breast cancer. The additional risk depends on the length of time you use HRT. The additional risk becomes apparent after about 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 between the ages of 50 and 54 who are not using HRT, on average, 13 to 17 out of 1,000 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 1,000 users (i.e., between 0 and 3 additional cases).
In women aged 50 who start HRT with estrogen-progestogen for 5 years, there will be 21 cases per 1,000 users (i.e., between 4 and 8 cases).
In women between the ages of 50 and 59 who are not taking HRT, on average, 27 cases of breast cancer will be diagnosed per 1,000 women over a 10-year period. In women aged 50 who start estrogen-only HRT for more than 10 years, there will be 34 cases per 1,000 users (i.e., 7 additional cases). In women aged 50 who start HRT with estrogen-progestogen for 10 years, there will be 48 cases per 1,000 users (i.e., 21 additional cases).
Examine your breasts regularly. Consult your doctor if you notice any of the following changes:
Ovarian cancer
Ovarian cancer is uncommon (much less common than breast cancer). The use of HRT with only estrogens or combined estrogen-progestogen has been associated with a slight increase in the 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 receiving HRT, about 2 out of 2,000 will be diagnosed with ovarian cancer over a 5-year period. In women treated with HRT for 5 years, there will be about 3 cases per 2,000 users (i.e., about 1 additional case).
Effect of HRT on the heart and circulation
Blood clots in a vein (thrombosis)
The risk of blood clots in the veinsis approximately 1.3 to 3 times higher among HRT users compared to non-users, especially during the first year of treatment.
Blood clots can be serious and, if they reach the lungs, can cause chest pain, difficulty breathing, fainting, and even death.
You are more likely to have a blood clot in the veins with age and if any of the following apply to you. Inform your doctor if any of these situations apply to you:
For signs of blood clots, see "Stop taking Estradiol Meriestra and visit your doctor immediately".
Comparison
In women in their fifties who are not taking HRT, on average, 4 to 7 out of 1,000 will have a blood clot in a vein over a 5-year period.
In women in their fifties who have been taking HRT with estrogen-progestogen for 5 years, there will be 9 to 12 cases per 1,000 users (i.e., 5 additional cases).
Additional warning for estrogen-only products: In women in their fifties who have had a hysterectomy and have been taking HRT with estrogen only for 5 years, there will be between 5 and 8 cases per 1,000 users (i.e., 1 additional case).
Heart disease (heart attack)
There is no evidence that HRT will prevent a heart attack.
Women over 60 who take HRT with estrogen-progestogen are slightly more likely to develop heart disease than those who do not take any HRT.
In women who have had a hysterectomy and are taking estrogen-only therapy, there is no increased risk of developing heart disease.
Stroke
The risk of having a stroke is about 1.5 times higher among HRT users compared to non-users. The number of additional stroke cases due to HRT use increases with age.
Comparison
In women in their fifties who do not take HRT, on average, 8 out of 1,000 will have a stroke. In women in their fifties who receive HRT, there will be 11 cases per 1,000 users over a 5-year period (i.e., 3 additional cases).
HRT and other disorders
HRT will not prevent memory loss. Some tests suggest that there may be a higher risk of memory loss among women who start using HRT after the age of 65. Consult your doctor.
Estradiol use may cause fluid retention in the body. If you have kidney or heart failure, you should be monitored by your doctor while taking estradiol.
In some cases, estrogen use can significantly increase the level of lipids in the blood, and in rare cases, cause pancreatitis. If you have very high levels of triglycerides in the blood (hypertriglyceridemia), you should be monitored while taking estradiol.
Consult your doctor if you identify with any of the above warnings or if they have occurred in the past.
Other medications and Estradiol Meriestra
Some medications may reduce the effectiveness of Estradiol Meriestra. This may result in irregular bleeding. This can occur with the following medications:
HRT may affect the functioning of other medications:
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medication. Your doctor will inform you about this.
Lab tests
If you need to have blood tests, inform your doctor or the laboratory staff that you are taking estradiol, as this medication may affect the results of some tests.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
Estradiol Meriestra should only be used in postmenopausal women. If you become pregnant, stop taking this medication and contact your doctor.
Pregnancy
If you are pregnant, you should not take Estradiol Meriestra. If you become pregnant while taking Estradiol Meriestra, you should stop treatment immediately.
Breastfeeding
You should not take Estradiol Meriestra during breastfeeding.
Driving and using machines
Estradiol Meriestra does not affect your ability to drive or use machines.
Estradiol Meriestra contains lactose
If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.
Follow exactly the administration instructions of this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again. Your doctor will prescribe the lowest possible dose to treat symptoms for the minimum time. Consult your doctor if you think the prescribed dose is too high or too low.
The recommended dose is:
Treatment for symptoms of estrogen deficiency in postmenopausal women:
Generally, your doctor will prescribe half a tablet of Estradiol Meriestra once a day at the start of treatment. If necessary (e.g., desired results are not obtained after 3 months), your doctor may adjust the dose.
Women with a uterus:
Long-term use of estrogens without the inclusion of progestogens increases the risk of endometrial cancer in women with a uterus. Estrogens should be taken along with progestogen tablets for at least 12 days a month to reduce this risk.
Two different treatments may be prescribed:
Cyclic treatment:
Take half or 1 tablet of Estradiol Meriestra per day for 21 days (3 weeks), followed by a 7-day break.
Usually, your doctor will also prescribe a treatment with a hormone called progestogens. You should take progestogen tablets during the last 12-14 days of the 21-day estrogen cycle. During the fourth week, when you are not taking any medication, you will also not take progestogens. During the time you are taking a break from treatment, you may experience withdrawal bleeding (menstruation).
Continuous treatment:
Take half or 1 tablet of Estradiol Meriestra every day without interruption.
Usually, your doctor will also prescribe another hormone called progestogens.
You should take progestogen tablets during the last 12-14 days of the month. You may experience withdrawal bleeding (menstruation) during treatment when estrogens are administered in combination with progestogens.
Women without a uterus:
Unless you have a condition where uterine wall cells come out of the uterus (endometriosis), estrogen treatment should not be administered with progestogens if you have had your uterus removed. Take half or 1 tablet of Estradiol Meriestra once a day without interruption.
The tablet can be divided into equal doses by placing the tablet on a firm surface with the marks facing down and pressing it.
If you use Estradiol Meriestra for the treatment of menopausal symptoms and notice that the effects of Estradiol Meriestra are too strong or too weak, consult your doctor.
If you have previously taken other HRTs, consult your doctor or pharmacist when you should start taking Estradiol Meriestra.
Prevention of osteoporosis
1 tablet of Estradiol Meriestra per day, as determined by your doctor.
Take the tablet with a sufficient amount of liquid (e.g., a glass of water).
How long should you take Estradiol Meriestra?
From time to time, you should talk to your doctor about the possible risks associated with Estradiol Meriestra and whether you need to continue treatment. It is essential that you take the minimum effective dose and only for the necessary time.
If you take more Estradiol Meriestra than you should
If you have taken more Estradiol Meriestra than you should, consult your doctor, pharmacist, or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medication and the amount ingested. Among the symptoms that may occur are nausea, vomiting, and withdrawal bleeding.
If you forget to take Estradiol Meriestra
If you have forgotten to take a tablet, take it as soon as possible. If more than 12 hours have passed, continue with the treatment as usual without taking the missed tablet. Do not take a double dose to make up for missed doses. If you have already forgotten to take a tablet previously, you may experience withdrawal bleeding.
If you need surgery
If you are going to undergo surgery, you should inform the surgeon that you are taking Estradiol Meriestra. You may need to stop taking Estradiol Meriestra 4 to 6 weeks before the operation to avoid the risk of blood clots (see section 2, "Blood clots in a vein (thrombosis)"). Consult your doctor when you can restart treatment with Estradiol Meriestra.
If you stop treatment with Estradiol Meriestra
Stopping Estradiol Meriestra 2 mg may increase the risk of bleeding or spotting. If this occurs after stopping treatment, contact your doctor immediately. Your doctor should determine the reason for this. After a prolonged interruption of treatment, consult your doctor before taking Estradiol Meriestra again.
If you have any other questions about the use of this medication, ask your doctor or pharmacist.
