estradiol and dydrogesterone

Consumer Medicine Information (CMI)

This leaflet answers some common questions about Femoston.

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.

Do not use Femoston or other estrogens, with or without a progestogen to prevent heart attacks, stroke or dementia.

A study called the Women’s Health Initiative indicated increased risk of heart attack, 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.

The Women’s Health Initiative Memory Study indicated increased risk of dementia in women aged 65-79 years taking conjugated estrogens and MPA. There are no comparable data currently available for others doses of conjugated estrogens and MPA or others 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 Femoston.

Treatment with estrogens, with or without progestogens should be used at the lowest effective dose and for the shortest period of time.

Femoston is a type of treatment called hormone replacement therapy (HRT). It contains the hormones estradiol and dydrogesterone.

This medicine helps to relieve the discomfort many women feel during and after the menopause. It also helps to prevent thinning of the bones (osteoporosis), which can cause fractures. Femoston is used by women who still have a uterus (womb).

Menopause may be natural or occur after surgery or medical treatment. HRT should not be used for the long-term maintenance of general health or to prevent heart disease. Femoston is not a contraceptive (birth control) and will not prevent pregnancy or restore fertility. Since pregnancy may be possible early in the menopause while you are still having menstrual periods, you should ask your doctor to suggest another (non-hormonal) method of birth control.

Estradiol is a natural female sex hormone called an estrogen. It is the same hormone that your ovaries were producing before the menopause. Dydrogesterone is a hormone called a progestogen. It has effects like the female hormone, progesterone, which your ovaries also produced before the menopause.

Menopause generally occurs between the ages of 45 and 55, because your body’s production of estrogen decreases. 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 these symptoms.

After the age of 40, and especially after the menopause, some women develop osteoporosis. This is a thinning of the bones that makes them weaker and more likely to break, especially the bones of the spine, hip and wrist. The risk of osteoporosis is increased by lack of estrogen. Estrogens can be given to reduce this risk if other treatments are not suitable.

Women who still have a uterus must take both estrogen and progestogen as part of HRT. This is because estrogen stimulates the growth of the lining of the uterus (called the endometrium). Before menopause this lining is removed during your period through the action of your natural progestogen. After menopause, taking estrogen on its own as HRT may lead to irregular bleeding and to a disorder called endometrial hyperplasia. Progestogens such as dydrogesterone help to protect the lining of the uterus from developing this disorder.

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.

HRT should only be used if you have been fully informed of the risks.

The decision to use HRT should be based on your symptoms and health, and made after a careful medical evaluation.

Tell your doctor if you are likely to have an increased risk of developing blood clots in your blood vessels.

The risk increases as you get older and it may also be increased if:

anyone in your immediate family has ever had blood clots in the blood vessels of the legs or lungs

you are overweight

you have varicose veins

you have a disorder called systemic lupus erythematosus (SLE).

Your doctor will advise you whether or not to take Femoston, or if you need to adjust the dose, or adapt your treatment.

Tell your doctor 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 Femoston may interfere with each other. These include:

herbal medicines containing St John’s wort

some medicines for epilepsy such as phenytoin, phenobarbital (phenobarbitone) and carbamazepine

some antibiotics and anti-infectives such as rifampicin and ritonavir

some medicines with a narrow therapeutic index such as tacrolimus, ciclosporin, fentanyl and theophylline

These medicines may be affected by Femoston, 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 Femoston.

Follow all directions given to you by your doctor 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.

If you are having regular periods, you may start taking Femoston on the first day of your period. If you are having irregular periods, discuss the starting day with your doctor. If you have not had a period for 12 months or more, you can start Femoston immediately.

The usual dose is one tablet daily.

Swallow the tablets whole with a glass of water.

It does not matter if you take this medicine before or after food.

Take Femoston 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 tablets are labelled with the days of the week to help you make sure you are taking your tablets every day.

You must always start by taking the tablets in the half of the pack with an arrow marked “1”. When you come to the end of these tablets, start taking the tablets in the other half of the pack marked “2”.

You should start each new pack the day after you have finished the old pack. Do not leave a gap between packs.

Your doctor can advise you how long you may need to take Femoston.

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. The studies also showed that 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 in the risk of dementia, including Alzheimer’s disease. It is not known if this finding applies to younger women.

Continue taking Femoston for as long as your doctor recommends.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

A slight vaginal bleeding, like an irregular period, may occur.

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.

If you have forgotten to take more than one tablet, discuss this with your doctor.

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.

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 Femoston. Do this even if there are no signs of discomfort or poisoning.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Femoston.

Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.

Tell your doctor that you are using Femoston well in advance of any expected hospitalisation or surgery. If you go to hospital unexpectedly, tell the doctor who admits you that you are using it.

The risk of developing blood clots in your blood vessels may be temporarily increased after surgery, serious injury or having to stay in bed for a long period of time. If possible, Femoston should be stopped at least 4 weeks before surgery and it should not be restarted until you are fully mobile.

If you become pregnant while you are taking this medicine, tell your doctor or pharmacist immediately.

See your doctor at least once a year for a check-up. Some women will need to go more often. Your doctor will check:

your breasts and order a mammogram at regular intervals

your uterus and cervix and do a pap smear at regular intervals

your blood pressure and cholesterol level

Check your breasts each month and report any changes promptly to your doctor.

Your doctor or nurse can show you how to check your breasts properly.

If you notice any changes to your breasts, see your doctor.

Include foods that are good sources of calcium and Vitamin D in your daily diet and exercise regularly. Calcium, Vitamin D and exercise may help prevent thinning of the bones. Your doctor can advise you on which foods and types of exercise are best for you.

Do not use this medicine to treat any other complaints unless your doctor or pharmacist tells you to.

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not stop taking Femoston, or change the dosage, without checking with your doctor.

Tell your doctor as soon as possible if you do not feel well while you are taking Femoston.
