1. WHAT ZUMENON IS AND WHAT IT IS USED FOR
Zumenon is a Hormone Replacement Therapy (HRT). It
contains the female hormone oestrogen. Zumenon is
used in postmenopausal women with at least 6 months
since their last natural period and women switching from
standard (cyclic or sequential) HRT on the advice of their
Zumenon is used for:
Relief of symptoms occurring after menopause
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"). Zumenon alleviates these symptoms after
menopause. You will only be prescribed Zumenon if your
symptoms seriously hinder your daily life.
2. BEFORE YOU TAKE ZUMENON
Medical history and regular check-ups
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 Zumenon 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 Zumenon.
Go for regular breast screening, as recommended by your
Do not take Zumenon
If any of the following applies to you. If you are not sure
about any of the points below, talk to your doctor before
Do not take Zumenon
• 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 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 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
• If you are allergic (hypersensitive) to oestradial
or any of the other ingredients of Zumenon (listed
in section 6 Further information)
• if you still have your womb and are not currently
taking some form of progestogen hormone
If any of the above conditions appear for the first
time while taking Zumenon, stop taking it at once
and consult your doctor immediately.
When to take special care with Zumenon
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 Zumenon. 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 (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 tumour
• 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 cardiac or kidney problems
Stop taking Zumenon and see a doctor immediately
If you notice any of the following when taking HRT:
- any of the conditions mentioned in the ‘DO NOT
take Zumenon’ 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, tiredness, dizziness).
- migraine-like headaches which happen for the first
- 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
Note: Zumenon 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
You will have a bleed once a month (so-called withdrawal
bleed) while taking Zumenon. But, if you have unexpected
bleeding or drops of blood (spotting) besides your
monthly bleeding, which:
• carries on for more than the first 6 months
• starts after you have been taking Zumenon more than
• carries on after you have stopped taking Zumenon
see your doctor as soon as possible
Evidence suggests that taking 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
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
Ovarian cancer is rare - much rarer than breast
cancer. The use of oestrogen-only or combined
oestrogen-progestagen 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, on
average 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 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
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 longterm treatment with a medicine used to prevent blood
• 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 taking Zumenon and
see a doctor immediately”.
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 oestrogenprogestogen 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 oestrogenprogestogen HRT are slightly more likely to develop heart
disease than those not taking any HRT.
For women who have had their womb removed and are
taking 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 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.
Using other medicines
Some medicines may interfere with the effect of Zumenon.
This might lead to irregular bleeding. This applies to the
• Medicines for epilepsy (such as phenobarbital,
phenytoin and carbamazepin)
• Medicines for tuberculosis (such as rifampicin,
• Medicines for HIV infection (such as nevirapine,
efavirenz, ritonavir and nelfinavir)
• Herbal remedies containing St John’s Wort
Problems due to high levels of the following medicines
may occur when you take Zumenon so careful drug
monitoring and dose decrease may become necessary:
- tacrolimus and cyclosporin – used, for example, for
- fentanyl – a painkiller
- theophylline – used for asthma and other breathing
HRT and cancer
Excessive thickening of the lining of the womb
(endometrial hyperplasia) and cancer of the lining of
the womb (endometrial cancer)
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
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
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.
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.
If you need a blood test, tell your doctor or the laboratory
staff that you are taking Zumenon, because this medicine
can affect the results of some tests.
Pregnancy and breast-feeding
Zumenon is for use in peri and postmenopausal women
only. If you become pregnant, stop taking Zumenon and
contact your doctor.
Important information about some of the
ingredients of Zumenon
Zumenon tablets contain milk sugar (lactose). If you have
been told by your doctor that you have an intolerance to
some sugars, contact your doctor before taking this
3. HOW TO TAKE ZUMENON
Always take Zumenon exactly as your doctor has told
you. You should check with your doctor or pharmacist
if you are not sure.
Take one tablet every day, without a break between
packs. Swallow the tablet with water, with or without
In women with a uterus, a progestagen should normally
be added to Zumenon for 12 - 14 days of each month.
If you are having regular periods you should start taking
Zumenon on day one of bleeding.
If you are not having regular periods and are not taking
any other HRT preparations, or you are switching from a
combined continuous HRT product, you can start taking
Zumenon on any convenient day.
If you are currently using a ‘cyclic’ or ‘sequential’ HRT
preparation (which involves taking an oestrogen tablet or
patch for part of the month, followed by both oestrogen
and progestagen tablet or patch for up to 14 days) start
taking Zumenon the day after you finish the pack i.e. at
the end of the progestagen phase.
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
You may experience some irregular bleeding or light
bleeding (spotting) during your first few months of taking
Zumenon. If the bleeding is troublesome, or continues
beyond the first few months of treatment you should
discuss this with your doctor.
If you take more Zumenon than you should
If you or somebody else takes too many Zumenon tablets,
they are unlikely to come to any harm. Nausea (feeling
sick), vomiting, sleepiness, dizziness and withdrawal
bleeding may occur. No treatment is necessary, but if you
are worried contact your doctor for advice.
If you forget to take Zumenon
Take the missed tablet as soon as you remember. If it is
more than 12 hours since you took the last one, take the
next dose without taking the forgotten tablet. Do not take
a double dose. Bleeding or spotting may occur if you
miss a dose.
If you need to have surgery
If you are going to have surgery, tell the surgeon that you
are taking Zumenon. You may need to stop taking
Zumenon 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 taking
If you stop taking Zumenon
Do not stop taking Zumenon without first talking to your
If you have any further questions on the use of this
product, ask your doctor or pharmacist
