Contents of the package leaflet
Ovestinon belongs to a group of medicines called hormone replacement therapy (HRT). It contains the female hormone estriol (estrogen). Ovestinon is used in postmenopausal women who have had their last natural menstrual period at least 12 months ago.
It is used to relieve symptoms of menopause in the vagina, such as dryness or irritation. In medical terms, this is known as "vaginal atrophy". This is caused by a fall in estrogen levels in your body. This happens naturally after menopause.
If your ovaries are surgically removed (oophorectomy) before menopause, the decrease in estrogen production occurs very abruptly.
The lack of estrogen during menopause can cause the vaginal wall to become thin and dry (vaginal dryness). Therefore, sexual intercourse can become painful and may cause vaginal irritation and infections. The lack of estrogen can also lead to symptoms such as urinary incontinence and recurrent cystitis.
Ovestinon works by replacing the estrogen that is normally produced by the ovaries. It is inserted into your vagina, so the hormone is released where it is needed. This can relieve vaginal discomfort.
It may take several days or even weeks before you notice an improvement.
In addition to the uses mentioned above, Ovestinon may be used to:
help with the study of the cervical smear (Pap test) in postmenopausal women.
Medical history and medical examinations
The use of hormone replacement therapy involves risks that need to be considered when deciding whether to start treatment or continue it.
Experience with treatment in women with premature menopause (due to ovarian failure or surgical intervention) is limited. If you have premature menopause, consult your doctor, as the risks of using hormone replacement therapy may be different.
Before you start (or restart) hormone replacement therapy, your doctor will ask you about your medical history and that of your family. Your doctor may decide to perform a physical examination, which may include a breast examination and/or an internal examination, if necessary.
Once you have started taking Ovestinon, 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 Ovestinon with your doctor.
Have regular mammograms as recommended by your doctor.
Do not use Ovestinon
If any of the following applies to you, or if you are not sure, consult your doctorbefore using Ovestinon.
Do not use Ovestinon:
If any of the above conditions appear for the first time while taking Ovestinon, stop taking it immediately and consult your doctor.
Warnings and precautions
Consult your doctor before starting Ovestinon if you have had any of the following problems, as they may come back or get worse during treatment with Ovestinon. If so, you should see your doctor more often for medical check-ups:
Tell your doctor if you have hepatitis C and are taking the combination of medicines ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. The combination of these medicines with other medicines that contain estrogen may cause increases in blood tests of liver function (elevations of liver enzymes (ALT)). It is currently unknown whether this risk occurs with Ovestinon.
Stop using Ovestinon and see your doctor immediately
If you notice any of the following while taking hormone replacement therapy:
For more information, see "blood clots in a vein (thrombosis)".
Hormone replacement therapy and cancer
Excessive thickening of the lining of the uterus (endometrial hyperplasia) and cancer of the lining of the uterus
Taking HRT tablets that contain only estrogen for a long time may increase the risk of developing cancer of the lining of the uterus (endometrium).
It is not clear if there is a similar risk with Ovestinon used for repeated or long-term treatment (more than one year). However, it has been shown that the absorption of Ovestinon into the bloodstream is very low; therefore, the addition of a progestogen is not necessary.
If you bleed or spot, it is usually nothing to worry about, but you should make an appointment to see your doctor. It could be a sign that the endometrium has become thicker.
To avoid endometrial stimulation, do not exceed the maximum daily dose, and do not use this maximum dose for more than a few weeks.
The following risks apply to hormone replacement therapy medicines that circulate in the blood. However, Ovestinon is for local treatment in the vagina and its absorption into the blood is very low. It is less likely that the conditions mentioned below will get worse or come back during treatment with Ovestinon, but you should consult your doctor if you are concerned.
Breast cancer
Available data indicate that using Ovestinon does not increase the risk of breast cancer in women who have not had breast cancer in the past. It is not known if Ovestinon can be used safely in women who have had breast cancer in the past.
Check your breasts regularly. See your doctor if you notice any change, such as:
In addition, you are advised to participate in breast cancer screening programs when they are offered.
Ovarian cancer
Ovarian cancer is rare, much rarer than breast cancer. The use of HRT that contains estrogen only has been associated with a slightly increased risk of ovarian cancer.
The risk of ovarian cancer varies with age. For example, in women aged 50-54 who are not taking HRT, about 2 women in 2000 will be diagnosed with ovarian cancer over a 5-year period. For women who have been taking HRT for 5 years, there will be about 3 cases per 2000 users (i.e., about 1 extra case).
Effect of hormone replacement therapy on the heart and circulation
Blood clots in a vein
The risk of blood clots in the veinsis approximately 1.3 to 3 times higher in women using hormone replacement therapy than in those not using it, especially during the first year of treatment.
Blood clots can be serious, and if one travels to the lungs, it can cause chest pain, shortness of breath, fainting, or even death.
The likelihood of having a blood clot in the veins increases with age and if you are affected by any of the following conditions. Tell your doctor if any of these apply to you:
To know the signs of a blood clot, see the section "Stop using Ovestinon and see your doctor immediately".
Comparison
On average, 4 to 7 out of 1,000 women in their 50s who are not taking hormone replacement therapy may have a blood clot in a vein over a 5-year period. In women in their 50s who have been taking hormone replacement therapy that contains only estrogen for more than 5 years, there will be 5 to 8 cases per 1,000 users (i.e., 1 extra case).
Heart disease (heart attack)
Women taking only estrogen do not have an increased risk of developing heart disease.
Stroke
The risk of having a stroke is about 1.5 times higher in women using hormone replacement therapy than in those not using it. The number of extra stroke cases due to hormone replacement therapy increases with age.
Comparison
On average, 8 out of 1,000 women in their 50s who are not taking hormone replacement therapy may have a stroke over a 5-year period. In women in their 50s taking hormone replacement therapy for more than 5 years, there will be 11 cases per 1,000 users (i.e., 3 extra cases).
Other warnings
Hormone replacement therapy does not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start hormone replacement therapy after the age of 65. Ask your doctor for advice.
Note:Ovestinon is not a contraceptive and should not be used as such. If it has been less than 12 months since your last menstrual period or you are under 50, you may still need to use a contraceptive method to prevent pregnancy. Ask your doctor for advice.
Other medicines and Ovestinon
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines, including those obtained without a prescription, herbal medicines, or other natural products.
Some medicines may interfere with the effect of Ovestinon, or Ovestinon may interfere with the effect of other medicines. This could cause irregular bleeding. This occurs with the following medicines:
Tell your doctor if you have hepatitis C and are taking the combination of medicines ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. The combination of these medicines with other medicines that contain estrogen may cause increases in blood tests of liver function (elevations of liver enzymes (ALT)). It is currently unknown whether this risk occurs with Ovestinon.
Using Ovestinon with food and drink
You can eat and drink normally while taking Ovestinon.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Ovestinon should only be used by postmenopausal women. If you become pregnant, stop taking Ovestinon and contact your doctor.
If you are breastfeeding, consult your doctor before using Ovestinon, as it is excreted in breast milk.
Driving and using machines
Ovestinon is not expected to affect your ability to drive a car or operate machinery. However, individual responses to the medicine may vary.
Lab tests
If you need to have a blood test, tell your doctor or the laboratory staff that you are using Ovestinon, as this medicine may affect the results of some tests.
Ovestinon contains macrogol ceto-stearyl ether
Macrogol ceto-stearyl ether may cause local skin reactions (e.g., contact dermatitis).
Follow exactly the administration instructions of this medication indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.
The recommended dose for vaginal discomfort is one ovule per day for the first few weeks (–maximum 4 weeks) and then the dose is gradually decreased to, for example, one ovule twice a week.
To improve wound healing in postmenopausal women undergoing vaginal surgery, the usual dose is one ovule daily for 2 weeks before surgery; after surgery, one ovule twice a week for 2 weeks.
To help evaluate vaginal smears in postmenopausal women, the usual dose is 1 ovule daily every day of the week before the test.
Your doctor may interrupt treatment every 2-3 months for a period of 4 weeks to assess whether it is necessary to continue.
For other situations, a different dose may be prescribed.
Instructions for the correct administration of the preparation
It is advisable to apply the ovule before going to bed. While in a lying position, an ovule will be inserted into the vagina as deeply as possible. The ovules are not intended for rectal insertion.
The maximum dose (1 ovule per day) should not be used for more than 2-3 weeks.
Your doctor will try to prescribe the lowest dose to treat your symptoms for the shortest necessary time. If you feel that the effect of Ovestinon is too strong or too weak, inform your doctor.
If you use more Ovestinon than you should
In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount ingested.
In the case of accidental ingestion of some ovules, the symptoms that may appear are nausea and vomiting; in women and girls, vaginal bleeding may also occur after a few days.
If you forget to use Ovestinon
Do not use a double dose to make up for forgotten doses.
If you forget to administer a dose, do so when you remember, unless you realize on the same day that you are due for the next dose. In this case, do not administer it and simply apply the dose for that day in the usual way.
If you need to undergo surgery
If you are going to undergo surgery, inform the surgeon that you are using Ovestinon. You may need to stop using Ovestinon 4 to 6 weeks before the operation to reduce the risk of a blood clot (see section 2, Blood clots in a vein). Ask your doctor when you can start using Ovestinon again.
If you have any other doubts about the use of this medication, ask your doctor or pharmacist.
Like all medications, this medication can cause side effects, although not all people experience them.
In comparison with women who do not use hormone replacement therapy, the following diseases have been reported more frequently in women who use hormone replacement therapy that circulates in the blood. These risks affect fewer treatments administered via the vaginal route, such as Ovestinon:
See section 2 for more information on these side effects.
Depending on the dose and the patient's sensitivity, Ovestinon may rarely cause side effects such as:
