What is in this leaflet

This leaflet answers some common questions about Zumenon.
It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.

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 combinations.
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 symptoms.
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.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food store.
Some medicines and Zumenon may interfere with each other. These include:
herbal medicines containing St John’s Wort
some medicines used to treat epilepsy
some antibiotic and anti-infective medicines
some medicines which require precise dosing e.g. tacrolimus, ciclosporin, fentanyl and theophylline
These medicines may be affected by Zumenon, or may affect how well it works. You may need to use different amounts of your medicine, or take different medicines.
Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking Zumenon.

Special Warning

Treatment with estrogens alone over a prolonged period may expose women with an intact womb to an increased risk of cancer of the lining of the womb.

How to take Zumenon

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

The usual dose is one tablet daily.
If you have not had a period for twelve months or more or if you have had a hysterectomy, you can start Zumenon immediately.
If you are having irregular periods, start taking Zumenon on day 5 of the menstrual cycle.
If your uterus is still intact your doctor will generally prescribe another medicine (progesterone) to take with Zumenon during part of your menstrual cycle.

How to take it

Swallow the tablet whole with a glass of water.

When to take it

Take Zumenon at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
The pack is labelled with the days of the week to help you with taking your tablets every day.
You should start each new pack the day after you have finished the current pack. Do not leave a gap between packs.

How long to take it

Your doctor can advise you how long you may need to take Zumenon.
Your doctor can discuss the risks and benefits of long-term treatment with HRT. Some recent studies have shown that women using HRT have a small increase in breast cancer 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.
Continue taking Zumenon for as long as your doctor recommends.

If you forget to take it

If it is less than 12 hours before your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for advice.

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (13 11 26), or go to Accident and Emergency at your nearest hospital, if you think you or anyone else may have taken too much Zumenon. Do this even if there are no signs of discomfort or poisoning.
