When you must not use Zumenon
Do not use Zumenon or other estrogens, with or without progestogen to prevent heart
attacks, stroke or dementia.
A study called the Women's Health Initiative indicated increased risk of stroke, breast
cancer, and blood clots in the legs or lungs in women receiving treatment with a product
containing conjugated estrogens 0.625 mg and the progestogen medroxyprogesterone acetate
(MPA). The researchers stopped the study after 5 years when it was determined the
risks were greater than the benefits in this group.
This Women's Health Initiative also indicated increased risk of stroke, and blood
clots in the legs or lungs in women receiving treatment with a product containing
conjugated estrogens 0.625 mg alone. The researchers stopped the study after 7 years
when it was determined the risks were greater than benefit in this group.
The Women's Health Initiative Memory Study indicated increased risk of dementia in
women aged 65 years or older taking conjugated estrogens and MPA. Increased risk of
dementia was also reported in women taking conjugated estrogens alone. There are no
comparable data currently available for other doses of conjugated estrogens and MPA
or other combinations of estrogens and progestogens. Therefore, you should assume
the risks will be similar for other medicines containing estrogen and progestogen
Talk regularly with your doctor about whether you still need treatment with Zumenon.
Treatment with estrogens, with or without progestogens should be used at the lowest
effective dose and for the shortest period of time.
What Zumenon is used for
Zumenon is a type of treatment called hormone replacement therapy (HRT). Zumenon tablets
contain a hormone called estradiol.
This medicine helps to relieve the symptoms many women feel during and after menopause.
Zumenon may be used by women who still have a uterus (womb). Menopause may be natural
or occur after surgery or medical treatment.
Women with an intact womb should generally be prescribed Zumenon and another medicine,
a progestogen, to protect the lining of the uterus from over stimulation.
HRT should not be used for the long-term maintenance of general health or to prevent
heart disease or dementia.
Zumenon is not suitable for birth control and it will not restore fertility.
How it works
Estradiol is a natural female sex hormone called an estrogen. It is the same hormone
that your ovaries were producing before the menopause.
Menopause generally occurs between the ages of 45 and 55, because your body's production
of estrogen decreases. It may happen sooner if the ovaries are removed by surgery
(e.g. total hysterectomy). This can cause unpleasant symptoms such as a feeling of
warmth in the face, neck and chest, "hot flushes" (sudden intense feelings of heat
and sweating throughout the body), sleep problems, irritability and depression. Some
women also have problems with urine control or with dryness of the vagina causing
discomfort during or after sex. Estrogens can be given to reduce or eliminate these
Ask your doctor if you have any questions about why it has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.

risk after several years of use. The risk increases with the length of HRT use.
Recent studies have also shown that HRT is associated with a small increase in the
risk of heart attacks, strokes, blood clots, including clots in the lungs. However,
the risk of hip fractures and bowel cancer may be reduced.
Another study has shown that in women older than 65 years, HRT is associated with
a small increase is the risk of dementia, including Alzheimer's disease. It is not
known if this finding applies to younger women.
