The name of your medicine is Estriol 0.5 mg pessary. Estriol 0.5mg pessary contains a medicine called estriol. This medicine belongs to a group of medicines called Hormone Replacement Therapy (HRT).
It is used to relieve menopausal symptoms in the vagina such as dryness or irritation. In medical terms, this is known as ‘vaginal atrophy’. It is caused by a drop in the levels of oestrogen in your body. This happens naturally after the menopause.
This medicine works by replacing the oestrogen which is normally produced in the ovaries of women. It is inserted into your vagina, so the hormone is released where it is needed. This may relieve discomfort in the vagina.
When women get older the ovaries gradually produce less oestrogen.
Shortage of oestrogens may cause the vaginal wall to become thin and dry. So sexual intercourse may become painful and you may get vaginal infections. These problems can be relieved by using medicines like Estriol 0.5mg pessary which contain oestrogen. It may take several days or weeks before you notice an improvement.
This medicine is used:
The use of HRT carries risks which need to be considered when deciding whether to start taking it, or whether to carry on taking it.
The experience in treating women with a premature menopause (due to ovarian failure or surgery) is limited. If you have a premature menopause, the risks of using HRT may be different. Please talk to your doctor.
Before you start (or restart) HRT, your doctor will ask about your own and your family’s medical history. Your doctor may decide to perform a physical examination. This may include an examination of your breasts and/or an internal examination, if necessary.
Once you have started on this medicine, you should see your doctor for regular check-ups (at least once a year). At these check-ups, discuss with your doctor the benefits and risks of continuing with this medicine.
Go for regular breast screening, as recommended by your doctor.
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 this medicine,
Do not use this medicine:
If any of the above conditions appear for the first time while using this medicine, stop taking it at once and consult your doctor immediately.
Tell your doctor if you have ever had any of the following problems, before you start the treatment, as these may return or become worse during treatment with this medicine. If so, you should see your doctor more often for check-ups:
Tell your doctor if you have Hepatitis C and you are taking the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. Taking the combination of these drugs with some estrogen-containing products may cause increases in liver function blood test results (increase in ALT liver enzyme); the risk of this happening with this medicine is currently unknown.
If you notice any of the following when taking HRT:
Note: this medicine is not a contraceptive. If it is less than 12 months since your last menstrual period or you are under 50 years old, you may still need to use additional contraception to prevent pregnancy. Speak to your doctor for advice.
Excessive thickening of the lining of the womb (endometrial hyperplasia) and cancer of the lining of the womb (endometrial cancer)
Taking oestrogen-only HRT tablets for a long time can increase the risk of developing cancer of the womb lining (the endometrium).
It is uncertain whether there is a similar risk with this medicine if used for repeated or long-term (more than one year) treatments. However, this medicine has been shown to have very low absorption into the blood, therefore, the addition of a progestagen is not necessary.
If you get bleeding or spotting, it is usually nothing to worry about, but you should make an appointment to see your doctor. It could be a sign that your endometrium has become thicker.
The following risks apply to hormone replacement therapy (HRT) medicines which circulate in the blood. However, this medicine is for local treatment in the vagina and the 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 this medicine, but you should see your doctor if you are concerned.
Breast cancer
Evidence suggests that using this medicine does not increase the risk of breast cancer in women who had no breast cancer in the past. It is not known if this medicine can be safely used in women who had breast cancer in the past.
Regularly check your breasts. See your doctor if you notice any changes such as:
Additionally, you are advised to join mammography-screening programs when offered to you.
Ovarian cancer
Ovarian cancer is rare – much rarer than breast cancer. The use of oestrogen-only HRT 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 to 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).
Blood clots in a vein (thrombosis)
The risk of blood clots in the veins is about 1.3 to 3-times higher in HRT users than in non-users, especially during the first year of taking it.
Blood clots can be serious, and if one travels to the lungs, it can cause chest pain, breathlessness, fainting or even death.
You are more likely to get a blood clot in your veins as you get older and if any of the following applies to you. Inform your doctor if any of these situations applies to you:
For signs of a blood clot, see “Stop taking this medicine and see a doctor immediately”.
Compare
Looking at women in their 50s who are not taking HRT, on average, over a 5-year period, 4 to 7 in 1000 would be expected to get a blood clot in a vein.
For women in their 50s who have been taking estrogen-only HRT for over 5 years, there will be 5 to 8 cases in 1000 users (i.e. 1 extra case).
Heart disease (heart attack)
For women taking estrogen-only therapy there is no increased risk of developing a heart disease.
Stroke
The risk of getting stroke is about 1.5 times higher in HRT users than in non-users. The number of extra cases of stroke due to use of HRT will increase with age.
Compare
Looking at women in their 50s who are not taking HRT, on average, 8 in 1000 would be expected to have a stroke over a 5-year period. For women in their 50s who are taking HRT, there will be 11 cases in 1000 users, over 5 years (i.e. an extra 3 cases).
HRT will not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start using HRT after the age of 65. Speak to your doctor for advice.

For vaginal complaints
For vaginal complaints, the usual dosage is 1 pessary daily during the first weeks (maximally 4 weeks); later on the dose is gradually decreased to, for instance, 1 pessary twice a week.
Your doctor will aim to prescribe the lowest dose to treat your symptoms for as short as necessary. Speak to your doctor if you think this dose is too strong or not strong enough.
If you need to have surgery
If you are going to have surgery, tell the surgeon that you are using this medicine. You may need to stop using this medicine about 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 this medicine again. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Before or after vaginal surgery
For improving wound healing in postmenopausal women undergoing vaginal surgery the usual dose is 1 pessary daily in the 2 weeks before surgery; 1 pessary twice a week in the 2 weeks after surgery.
To help assess cervical smears taken from postmenopausal women the usual dose is 1 pessary on every other day in the week before taking the next smear.
