1. What Estradot is and what it is used for
Estradot is a Hormone Replacement Therapy (HRT). It contains the
female hormone oestrogen. Estradot is used in postmenopausal women
with at least 12 months since their last natural period.
Estradot comes as a patch that is applied to the skin.
Estradot is used for:
Relief of symptoms occurring after menopause
During the menopause, the amount of oestrogen produced by a woman’s
body drops. This can cause symptoms such as hot face, neck and chest
("hot flushes"). Estradot alleviates these symptoms after menopause.
You will only be prescribed Estradot if your symptoms seriously hinder
your daily life.
Prevention of osteoporosis (for Estradot 50, 75 and 100 only)
After the menopause some women may develop fragile bones
(osteoporosis). You should discuss all available options with your doctor.
If you are at an increased risk of fractures due to osteoporosis and other
medicines are not suitable for you, you can use Estradot to prevent
osteoporosis after menopause.
2. What you need to know before you use Estradot
Medical history and regular check-ups
The use of HRT carries risks which need to be considered when deciding
whether to start using it, or whether to carry on using 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 Estradot, 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 Estradot.
Go for regular breast screening, as recommended by your doctor.
Do not use Estradot
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 Estradot,
Do not use Estradot:
• if you have or have ever had breast cancer, or if you are suspected of
• if you have cancer which is sensitive to oestrogens, such as cancer
of the womb lining (endometrium), or if you are suspected of having it;
• if you have any unexplained vaginal bleeding;
• if you have excessive thickening of the womb lining (endometrial
hyperplasia) that is not being treated;
• if you have or have ever had a blood clot in a vein (thrombosis), such
as in the legs (deep venous thrombosis) or the lungs (pulmonary
• if you have a blood clotting disorder (such as protein C, protein S or
• if you have or recently have had a disease caused by blood clots in the
arteries, such as a heart attack, stroke or angina;
• if you have or have ever had a liver disease and your liver function
tests have not returned to normal;
• if you have a rare blood problem called “porphyria” which is passed
down in families (inherited);
• if you are allergic (hypersensitive) to estradiol or any of the other
ingredients of this medicine (listed in section 6);
If any of the above conditions appear for the first time while using
Estradot, stop using it at once and consult your doctor immediately.
When to take special care with Estradot
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 Estradot. If so, you should see your doctor more
often for check-ups:
• fibroids inside your womb
• growth of womb lining outside your womb (endometriosis) or a history of
excessive growth of the womb lining (endometrial hyperplasia)
• increased risk of developing blood clots (see “Blood clots in a vein
• increased risk of getting an oestrogen-sensitive cancer (such as having
a mother, sister or grandmother who has had breast cancer)
• high blood pressure
• a liver disorder, such as a benign liver tumour
• migraine or severe headaches
• a disease of the immune system that affects many organs of the body
(systemic lupus erythematosus, SLE)
• a disease affecting the eardrum and hearing (otosclerosis)
• a very high level of fat in your blood (triglycerides)
• fluid retention due to cardiac or kidney problems
• products containing oestrogens may cause or worsen the symptoms of
hereditary angioedema. You should see your doctor immediately if you
experience symptoms of angioedema such as swollen face, tongue
and/or throat and/or difficulty swallowing, or hives together with difficulty
Taking a progestogen in addition to the oestrogen for at least 12 days of
each 28 day cycle protects you from this extra risk. So your doctor will
prescribe a progestogen separately if you still have your womb. If you
have had your womb removed (a hysterectomy), discuss with your doctor
whether you can safely take this product without a progestogen.
In women who still have a womb and who are not taking HRT, on
average, 5 in 1000 will be diagnosed with endometrial cancer between
the ages of 50 and 65.
For women aged 50 to 65 who still have a womb and who take
oestrogen-only HRT, between 10 and 60 women in 1000 will be
diagnosed with endometrial cancer (i.e. between 5 and 55 extra cases),
depending on the dose and for how long it is taken.
Estradot 75 and 100 contain a higher dose of oestrogens than other
oestrogen-only HRT products. The risk of endometrium cancer when
using Estradot 75 or 100 together with a progestogen is not known.
You will have a bleed once a month (so-called withdrawal bleed) while
using Estradot in combination with a progestagen. But, if you have
unexpected bleeding or drops of blood (spotting) besides your monthly
- carries on for more than the first 6 months
- starts after you have been using Estradot for more than 6 months
- carries on after you have stopped using Estradot
See your doctor as soon as possible.
Evidence suggests that taking combined oestrogen-progestogen and
possibly also oestrogen-only HRT increases the risk of breast cancer.
The extra risk depends on how long you take HRT. The additional risk
becomes clear within a few years. However, it returns to normal within a
few years (at most 5) after stopping treatment.
For women who have had their womb removed and who are using
oestrogen-only HRT for 5 years, little or no increase in breast cancer risk
Women aged 50 to 79 who are not taking HRT, on average, 9 to 17 in
1000 will be diagnosed with breast cancer over a 5-year period. For
women aged 50 to 79 who are taking oestrogen-progestogen HRT over 5
years, there will be 13 to 23 cases in 1000 users (i.e. an extra 4 to 6
• Regularly check your breasts. See your doctor if you notice any
changes such as:
• dimpling of the skin
• changes in the nipple
• any lumps you can see or feel
Ovarian cancer is rare. A slightly increased risk of ovarian cancer has
been reported in women taking HRT for at least 5 to 10 years.
Women aged 50 to 69 who are not taking HRT, on average about 2
women in 1000 will be diagnosed with ovarian cancer over a 5-year
period. For women who have been taking HRT for 5 years, there will be
between 2 and 3 cases per 1000 users (i.e. up to 1 extra case).
Effect of HRT on heart and circulation
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:
• you are unable to walk for a long time because of major surgery, injury
or illness (see also section 3, If you need to have surgery)
• you are seriously overweight (BMI >30 kg/m 2)
• you have any blood clotting problem that needs long-term treatment
with a medicine used to prevent blood clots
• if any of your close relatives has ever had a blood clot in the leg, lung or
• you have systemic lupus erythematosus (SLE)
• you have cancer.
For signs of a blood clot, see “Stop using Estradot and see a doctor
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
For women in their 50s who have been taking oestrogen-progestogen
HRT for over 5 years, there will be 9 to 12 cases in 1000 users (i.e. an
extra 5 cases).
For women in their 50s who have had their womb removed and have
been taking oestrogen-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)
There is no evidence that HRT will prevent a heart attack.
Women over the age of 60 years who use oestrogen-progestogen HRT
are slightly more likely to develop heart disease than those not taking any
For women who have had their womb removed and are taking oestrogenonly therapy there is no increased risk of developing a heart disease.
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.
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.
Other medicines and Estradot
Some medicines may interfere with the effect of Estradot. This might lead
to irregular bleeding. This applies to the following medicines:
• medicines for epilepsy (such as phenobarbital, phenytoin,
• medicines for tuberculosis (such as rifampicin, rifabutin),
• medicines for HIV infection (such as nevirapine, efavirenz, ritonavir,
• herbal remedies containing St John's Wort (Hypericum perforatum).
• other anti-infective medicines (such as ketoconazole, erythromycin).
Stop using Estradot and see a doctor immediately.
If you notice any of the following when using HRT:
- any of the conditions mentioned in the ‘Do Not use Estradot’ section
- yellowing of your skin or the whites of your eyes (jaundice). These may
be signs of a liver disease
- a large rise in your blood pressure (symptoms may be headache,
- migraine-like headaches which happen for the first time
- if you become pregnant
- if you notice signs of a blood clot, such as:
• painful swelling and redness of the legs
• sudden chest pain
• difficulty in breathing
For more information, see ‘Blood clots in a vein (thrombosis)’.
Please tell your doctor or pharmacist if you are taking or have recently
taken any other medicines, including medicines obtained without a
prescription, herbal medicines or other natural products.
Note: Estradot 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.
3. How to use Estradot
HRT and cancer
Excessive thickening of the lining of the womb (endometrial
hyperplasia) and cancer of the lining of the womb (endometrial
Taking oestrogen-only HRT will increase the risk of excessive thickening
of the lining of the womb (endometrial hyperplasia) and cancer of the
womb lining (endometrial cancer).
If you need a blood test, tell your doctor or the laboratory staff that you
are using Estradot, because this medicine can affect the results of some
Pregnancy and breast-feeding
Estradot is for use in postmenopausal women only. If you become
pregnant, stop using Estradot and contact your doctor. You should not
use Estradot if you are pregnant or while you are breast-feeding.
Driving and using machines
Estradot has no known effect on the ability to drive and use machines.
Always use this medicine exactly as your doctor has told you. Check with
your doctor or pharmacist if you are not sure.
Your doctor will aim to prescribe the lowest dose to treat your symptom
for as short as necessary. Speak to your doctor if you think this dose is
too strong or not strong enough.
How long to use Estradot
It is important that you use the lowest possible effective dose and only
as long as needed.
From time to time, you should discuss with your doctor whether you still
need the treatment.
When to start treatment
If you forget to use Estradot
• If you are currently not using any form of HRT (patches or tablets),
or if you have been using a continuous combined HRT product
(where oestrogen and the progestogen are given every day without
interruption), you can start to use Estradot on any convenient day.
• If you are changing from a cyclic or sequential HRT treatment
(where the progestogen is added for 12-14 days of the cycle), you should
start to use Estradot on the day after you complete your previous cycle.
If you forget to change the patch, change the patch as soon as you
remember. No matter what day this happens, go back to changing the
newly applied patch on the same days as your original schedule.
Do not use a double dose to make up for the forgotten patch.
When to apply Estradot
• An Estradot patch should be replaced twice weekly (every 3 to 4 days).
It is best to always replace it on the same two days of the week (e.g.
Monday and Thursday). Your Estradot pack contains a calendar checklist
on the back to help you remember your schedule. Mark the twice-a-week
schedule that you plan to follow. Always change the patch on the two
days of the week you have marked.
• Estradot should be worn continuously until it is time to replace it with a
Any adhesive that might remain on your skin can be easily rubbed off.
Then place the new Estradot patch onto a different area of skin.
Women without a uterus
The Estradot patch is applied continuously without a break. Additional
use of another type of hormone called progestogen is not required,
unless you have a condition where the lining of the uterus also grows
outside the uterus (endometriosis). Check the risks to be aware of with
HRT in general in section 2, When to take special care with Estradot.
If you stop using Estradot
Stopping use of Estradot may increase the risk of breakthrough bleeding
or spotting. Talk to your doctor if this occurs. After a long break in
treatment, consult your doctor before starting to use the patch again.
If you have any further questions on the use of this medicine, ask your
doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not
everybody gets them.
The following diseases are reported more often in women using HRT
compared to women not using HRT:
• breast cancer
• abnormal growth or cancer of the lining of the womb (endometrial
hyperplasia or cancer)
• ovarian cancer
• blood clots in the veins of the legs or lungs (venous thromboembolism)
• heart disease
• probable memory loss if HRT is started over the age of 65
For more information about these side effects, see Section 2.
Women with a uterus
Your doctor should give you another hormone called progestogen in
addition to Estradot to reduce the risk of cancer of the uterus. While
Estradot is applied continuously without a break, the progestogen tablet
should be taken for at least 12-14 days every month/28 day cycle. Check
the risks to be aware of with HRT in general in section 2, When to take
special care with Estradot.
Some effects could be serious

the effects mentioned above. Check the risks to be aware of with HRT in
general in section 2, When to take special care with Estradot.
When changing your patch, based on your twice-a-week schedule, apply
your new patch to a different site. Do not apply a new patch to that same
area for at least one week.
Other side effects

6. Contents of the pack and other information
What Estradot contains
Further useful information
Bathing, swimming, showering or exercising should not affect the patch if
it has been correctly applied. If a patch falls off, e.g. during bathing or
showering, shake it to remove the water. After careful drying and cooling
down of the skin, reapply the same patch on a different area of the lower
abdomen (see ‘Where to apply Estradot’).
If the patch does not stick completely to your skin, use a new patch. No
matter what day this happens, go back to changing this patch on the
same days as your original schedule.
When sunbathing or using a solarium, the patch should be covered.
When swimming, the patch can be worn under your bathing suit.
If you need to have surgery
If you are going to have surgery, tell the surgeon that you are using
Estradot. You may need to stop using Estradot 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 Estradot again.
If you use more Estradot than you should
Remove the patch if you have used too much Estradot. Symptoms of
overdose are usually tenderness of the breasts and/or vaginal bleeding.
Acute overdose is unlikely due to the way Estradot is used (patch). If
symptoms persist contact your doctor.
