How Oestrogel works
Oestrogel works by replacing the oestrogen in your
body. This is so that you have a similar amount of
oestrogen as before your menopause.

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
Before you start (or restart) HRT your doctor
will ask you 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.
Oestrogel is a Hormone Replacement Therapy
(HRT). It contains the female hormone oestrogen.
Oestrogel is used in postmenopausal women with
at least 6 months since their last natural period.
Once you have started on Oestrogel 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 Oestrogel.
Oestrogel is used for:
Relief of symptoms occurring after menopause
Go for regular breast screening, as recommended
by your doctor.
During the menopause, the amount of the
oestrogen produced by a woman’s body drops.
This can cause symptoms such as hot face, neck
and chest (“hot ﬂushes”). Oestrogel alleviates
these symptoms after menopause. You will only be
prescribed Oestrogel if your symptoms seriously
hinder your daily life.
Do not use Oestrogel
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 Oestrogel.
Do not use Oestrogel:
• If you have or have ever had breast cancer, or if
you are suspected of having it,
• If you have cancer which is sensitive to oestrogen,
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
• If you have or have ever had blood clots in a vein
(thrombosis), such as in the legs (deep venous
Prevention of osteoporosis
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 Oestrogel to prevent
osteoporosis after menopause.
thrombosis) or lungs (pulmonary embolism),
• If you have a blood clotting disorder (such as
protein C, protein S, or antithrombin deﬁciency),
• 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
• If you have a rare blood problem called “porphyria”
which is passed down in families (inherited),
• If you are allergic to oestradiol or any other
ingredients of this medicine (listed in section 6).
If any of the above conditions appear for the ﬁrst
time while using Oestrogel, stop using it at once
and consult your doctor immediately.
Warnings and precautions
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 Oestrogel. If so, you should see your
doctor more often for check-ups:
• ﬁbrosis 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 (thrombosis)”),
• increased risk of getting a 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 tumor,
• migraine or severe headaches,
• a disease of the immune system that affects
many organs of the body (Systemic Lupus
• a disease affecting the eardrum and hearing
• a very high level of fat in your blood (triglycerides),
• ﬂuid retention due to heart or kidney problems.
Stop using Oestrogel and see a doctor
If you notice any of the following when taking HRT:
• any of the conditions mentioned in the ‘Do not use
• 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, tiredness, dizziness)
• migraine-like headaches which happen for the
• 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

Note: Oestrogel 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.
HRT and cancer
Excessive thickening of the lining of the womb
(endometrial hyperplasia) and cancer of the
lining of the womb (endometrial cancer)
Using 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).
Using 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
In women who still have a womb and who are not
using HRT, on average, 5 in 1000 will be diagnosed
with endometrial cancer between the ages of 50
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
You may have irregular bleeding or drops of blood
(spotting) during the ﬁrst 3-6 months of using
Oestrogel. However, if the irregular bleeding:
• carries on for more than the ﬁrst 6 months
• starts after you have been using Oestrogel for
more than 6 months
• carries on after you have stopped using Oestrogel
see your doctor as soon as possible.
Evidence suggests that using combined oestrogenprogestogen 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 is shown.
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 oestrogenprogestogen HRT over 5 years, there will be 13 to
23 cases in 1000 users (i.e. an extra 4 to 6 cases).
• 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.
Additionally, you are advised to join mammography
screening programs when offered to you. For
mammogram screening, it is important that you
inform the nurse/healthcare professional who is
actually taking the x-ray that you use HRT, as this
medication may increase the density of your breasts
which may affect the outcome of the mammogram.
Where the density of the breast is increased,
mammography may not detect all lumps.
Ovarian cancer is rare, much rarer than breast
cancer. The use of oestrogen-only or combined
oestrogen-progestogen 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 using HRT for 5 years,
there will be about 3 cases per 2000 users (i.e.
about 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 using 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/m2)
• 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 another organ
• you have systemic lupus erythematosus (SLE)
• you have cancer.
For signs of a blood clot, see “Stop using Oestrogel
and see a doctor immediately”.
Looking at women in their 50s who are not using
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 using
oestrogen-progestogen HRT for over 5 years, there
will be 9 to 12 cases in 1000 users (i.e.an extra 5
For women in their 50s who have had their womb
removed and have been using 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
Women over the age of 60 years who use
oestrogen-progestogen HRT are slightly more likely
to develop heart disease than those not using any HRT.
For women who have had their womb removed
and are using oestrogen-only 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 using
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 using 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.
