1. WHAT ESTRADOT IS AND WHAT IT IS USED
Estradot is a hormone replacement therapy (HRT) and contains
the hormone oestrogen.
Estradot comes as a patch that is applied to the skin. The patch
releases small amounts of estradiol, which pass directly through
the skin into your bloodstream. Estradiol is identical to the natural
hormone oestrogen that is produced by the ovaries until the
menopause (the time when your menstrual periods stop).
Estradot is used for:
Relief of symptoms of the menopause
During the menopause, the amount of oestrogen produced by a
woman’s body drops. For some women this can cause unpleasant
symptoms such as hot face, neck and chest ("hot flushes"), sleep
problems, irritability and depression. Some women also have
problems with dryness of the vagina, which may cause discomfort
during or after sexual intercourse. Estradot can reduce or stop
these symptoms after the menopause.
Prevention of osteoporosis (for Estradot 50, 75 and 100 only)
Reduced oestrogen can increase the risk of osteoporosis.
Osteoporosis is a thinning of the bones that makes them weaker
and more likely to break. Taking oestrogens after the menopause
slows down bone loss and can help to prevent osteoporosis.
Estradot may be used to prevent osteoporosis after the menopause
in women who are at an increased risk of fractures but who are
unable to use other drugs approved for the prevention of
osteoporosis. Your doctor should discuss all the available options
The experience treating women older than 65 years is limited.
2. BEFORE YOU USE ESTRADOT
Do not use Estradot
if you have, or have ever had breast cancer, or think you might
if you have or have ever had any cancer which is sensitive to
oestrogens, such as cancer of the lining of the womb
(endometrium), or think you might have it;
if you have vaginal bleeding of unknown cause;
if you have abnormal growth of the womb lining
(endometrial hyperplasia) and you have not been treated for
if you have or have ever had a blood clot in your veins. This
may cause blockage of a blood vessel in the legs (deep vein
thrombosis) leading to thromboembolism, e.g. in the lungs
(pulmonary embolism) or other organs;
if you have thrombophilic disorders (e.g. protein C, protein S or
if you have or have ever had a heart attack, stroke or severe
chest pain due to angina (angina pectoris);
if you have or have ever had a liver disease and your liver
function has not returned to normal;
if you have porphyria (red blood pigment in your urine);
if you are allergic to estradiol or any of the other ingredients of

Take special care with Estradot
Estradot is not a transdermal contraceptive nor a fertility
treatment. If you are still capable of becoming pregnant you must
not use any hormone replacement therapy.
Estradot is a hormone replacement therapy. You need to be aware
of the general risks when using HRT.
If you have or have ever had any of the following conditions,
you need to let your doctor know. They may come back or get
worse during treatment with Estradot:
Benign tumours of the womb (e.g. myoma), endometrial
hyperplasia (abnormal growth of the womb lining) or
endometriosis (endometrial growths outside the uterus): Using
HRT products containing only oestrogens (such as Estradot) for
a long period can increase the risk of abnormal growth of the
womb lining (the endometrium) and endometrial cancer.
Adding a progestogen for at least 12 days every month/28 day
cycle greatly decreases this risk. During the first months of
treatment, irregular bleeding may occur.
Contact your doctor immediately:
if unexpected bleeding or spotting (breakthrough bleeding)
occurs after having used Estradot for some time or if this
continues after you stop treatment
if you have painful menstrual periods.
Your doctor should examine what the cause is.
If your womb has not been removed, you should also use the
hormone progestogen for 12–14 days a month/28 day cycle, in
addition to Estradot, as directed by your doctor.
Blood clots (thrombosis, lung embolism): You should not use
Estradot if you have ever had a blood clot in your veins.
HRT may increase the risk of blood clots, especially during the
first year of treatment.
Stop using Estradot and contact your doctor immediately if
painful swelling and redness of the legs
sudden chest pain
difficulty in breathing.
These symptoms may be signs of a blood clot.
Tell your doctor if any of the following applies to you:
if you are extremely overweight (BMI>30)
if you have had a blood clot before or if you or someone in
your close family has had blood clots
if you have any blood-clotting problem needing treatment
with a medicine (anticoagulant)
if you have had more than one miscarriage
if you are off your feet for a long time because of surgery,
injury or illness
if you are about to have an operation; it is best to stop
treatment 4 to 6 weeks before surgery.
Any of these will make your risk of a blood clot higher.
High blood pressure: Stop using Estradot and contact your
if an increase in blood pressure occurs while using Estradot.
Liver problems: You need to let your doctor know if you have
ever had liver problems, such as a benign tumour in the liver
Stop using Estradot and contact your doctor immediately,
if you get yellowing of the eyes and face (jaundice); this
could be a sign of liver problems.
Migraine or severe headache: Some studies with HRT have
shown a slightly increased risk of ischaemic stroke.
Stop using Estradot and contact your doctor immediately
if you get unexplained migraine-like headaches, with or
without disturbed vision. Headaches like these can be an
early sign of a stroke. If you have already had a stroke, talk
with your doctor about whether the benefits of the treatment
outweigh the possibly increased risk.
Breast cancer: You should not use Estradot if you have ever
had breast cancer. There is an increased risk of breast cancer
related to HRT. The risk increases the longer the treatment lasts
and decreases when treatment is stopped. Five years after
stopping treatment, the risk returns to that of women who have
never used HRT. The risk of breast cancer seems to be higher
for women using oestrogen in combination with progestogen
than for women who use products containing only oestrogen
(such as Estradot).
Contact your doctor if you notice any changes to your breasts,
dimpling of the breast skin
changes in the nipple
lumps that you can see or feel.
Your doctor may advise you to have regular breast check-ups,
including mammography. You need to let your doctor know if
you have a history of breast cancer or other oestrogen-sensitive
cancers in your immediate family (mother, sister or daughter).
Heart disease: You should not use Estradot if you have ever
had a heart attack or chest pain (angina pectoris). Studies
with HRT tablets have shown that women may be slightly more
likely to get heart disease during the first year of treatment. For
Estradot, it is not certain whether the risk is similar.
Stop using Estradot and contact a doctor immediately,
if you get pain in your chest that spreads to your arm or neck.
This pain may be a sign of heart disease.
Ischaemic Stroke: You should not use Estradot if you have
ever had an ischaemic stroke. See “migraine or severe
headache”. These can be warning signs of an ischaemic stroke.
Cancer of the ovaries: Some studies have shown that using
hormone therapy with oestrogens alone (such as Estradot) for
5–10 years may lead to a slightly increased risk of cancer of the
ovaries compared to women never treated with HRT. It is
suggested that long-term use of combined HRTs may confer a
similar, or slightly smaller risk.
Hypothyroidism: A condition in which your thyroid gland fails
to produce enough thyroid hormone and for which you are
treated with thyroid hormone replacement therapy.
Angioedema: Oestrogens may induce or exacerbate symptoms
of angioedema (episodes of rapid swelling of hands, feet, face,
lips, eyes, tongue, throat or digestive tract), in particular in
women with hereditary angioedema.
High fat levels in your blood which in rare cases may cause
inflammation of the pancreas.
Systemic lupus erythematosus (SLE), an autoimmune disorder
Hearing loss due to otosclerosis (a problem with the bones in
Tell your doctor before taking Estradot if you have ever had
any of the conditions above.
Before you start using Estradot your doctor should ask you about
your own and your family's medical history. Your doctor should
examine your breasts and your abdomen and may do an internal
examination. He/she should tell you what kind of changes in the
breast you should report to the doctor and may advise you to have
a breast X-ray (a mammogram). Once you have started Estradot,
you should see your doctor for regular check-ups (at least once a
year). At these check-ups your doctor should discuss with you the
benefits and risks of continuing to take Estradot.
Effects on laboratory tests
Using oestrogens may influence the results of certain laboratory
Tell your doctor that you use Estradot before undergoing a blood
Taking other medicines
Tell your doctor or pharmacist if you are taking or have
recently taken any other medicines, including medicines obtained
without a prescription. Some medicines may increase or decrease
the effect of Estradot, such as medicines containing:
phenobarbital, phenytoin or carbamazepine (used to treat
rifampicin, rifabutin (used to treat tuberculosis),
nevirapine, efavirenz, ritonavir, nelfinavir (used to treat HIV
St John's Wort (herbal medicine used to treat depression).
Pregnancy and breast-feeding
You should not use Estradot if you are pregnant or can still
become pregnant or while you are breast-feeding.
Stop using Estradot and contact your doctor immediately if
you become pregnant during Estradot treatment. Ask your doctor
or pharmacist for advice before taking any medicine.
Driving and using machines
Estradot has no known effect on the ability to drive and use
3. HOW TO USE ESTRADOT
Always use Estradot exactly as your doctor has told you. You
should check with your doctor or pharmacist if you are not sure.
During the treatment your doctor may adjust the dose according to
your individual needs.
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 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.
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 new patch.
Any adhesive that might remain on your skin can be easily rubbed
off. Then place the new Estradot patch onto a different area of
Make sure that the patch
sticks properly to your skin
and go over the edges with
your finger to ensure good
contact between the patch and
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, Take
special care with Estradot.
When changing the patch,
peel it off, fold it with the

discard it with normal
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, Take special care with Estradot.
