onsumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about the menopause ("change of life"), hormone replacement therapy and Estradot.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 using Estradot against the benefits they expect it will provide.If you have any concerns about using 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 Estradot
Do not use Estradot or other oestrogens, 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 oestrogens 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 oestrogens and MPA. There are no comparable data currently available for other doses of conjugated oestrogens and MPA or other combinations of oestrogens and progestogens. Therefore, you should assume the risks will be similar for other medicines containing oestrogen and progestogen combinations.
Talk regularly with your doctor about whether you still need treatment with Estradot. Treatment with oestrogens, with or without progestogens should be used at the lowest effective dose and for the shortest period of time.
What Estradot is used for
Estradot is a type of treatment called hormone replacement therapy (HRT). It is a stick-on patch that contains a hormone called oestradiol.Estradot is used for the short-term relief of symptoms of the menopause.HRT should not be used for the long-term maintenance of general health or to prevent heart disease or dementia.Estradot is not suitable for birth control and it will not restore fertility.How it works
Oestradiol is a natural female sex hormone called an oestrogen. It is the same hormone that your ovaries were producing before the menopause.The menopause occurs naturally in the course of a woman's life, usually between the ages of 45 and 55. It may happen sooner if the ovaries are removed by surgery (e.g. total hysterectomy). After menopause, your body produces much less oestrogen than it did before. 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 dryness of the vagina causing discomfort during or after sex. Oestrogens can be given to reduce or eliminate these symptoms.Estradot releases oestradiol in a continuous and controlled way just as your ovaries were doing before. Because the medicine does not have to pass through your stomach and liver, it allows you to take a much lower dose of oestrogen than would be needed in a tablet and helps to avoid some unpleasant side effects.Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another purpose.
This medicine is available only with a doctor's prescription. It is not habit-forming.
Before you use Estradot
When you must not use it
Do not use Estradot if you have an allergy to:
oestradiol, the active ingredient , or to any of the other ingredients listed at the end of this leaflet
any other medicine containing oestrogen, including the birth control pill
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.If you had a severe skin reaction in the past, you could have a very serious reaction if you use any type of oestrogen (patch, tablet, cream, etc.) again.Do not use Estradot if you have:
cancer of the breast or uterus (womb) or any other oestrogen dependent cancer, or you have had this condition in the past
blood clots in your blood vessels, now or in the past. You may have had painful inflammation of the veins or blockage of a blood vessel in the legs, lungs, brain or heart
a condition that increases the tendency for you to get blood clots
abnormal vaginal bleeding that has not been investigated
severe liver disease
a condition called porphyria
If you are not sure whether any of the above conditions apply to you, your doctor can advise you.Do not use Estradot if you are pregnant or breast-feeding. It may affect your baby.
If you still have a uterus (womb), do not use Estradot unless you are also taking another drug called a progestogen. Women who still have a uterus must take both oestrogen and progestogen as part of HRT. This is because oestrogen 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 a natural progestogen. After menopause, taking oestrogen on its own as HRT may lead to irregular bleeding and to a disorder called endometrial hyperplasia. Your doctor will prescribe a progestogen to protect the lining of the uterus from the effects of oestrogen.
Do not use this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. In that case, return it to your pharmacist.
Before you start to use it
Tell your doctor if you have:
a family history of breast cancer
nodules, lumps or cysts in your breasts or any other benign breast condition (not cancer)
endometriosis (a disorder of the uterus that may cause painful periods and abnormal bleeding)
fibroids or other benign tumours of the uterus (not cancer)
had one or more pregnancies where you lost the baby before birth
high blood pressure
kidney or liver problems
migraine or other severe headaches
gall bladder disease
hearing loss due to a problem with the bones in the ear called otosclerosis
a high level of triglycerides in the blood
a disorder called systemic lupus erythematosus (SLE)
low levels of thyroid hormone
a bone disease causing high calcium levels in the blood
very low calcium levels in the blood
had a problem in the past with jaundice (a liver problem) or itching skin when you took an oestrogen (e.g. the birth control pill or HRT)
a skin condition that could be made worse by applying the patch
Your doctor may want to take special precautions if you have any of the above conditions.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)
Taking other medicines
Tell your doctor if you are taking birth control pills. Estradot is not a contraceptive. 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.
Tell your doctor or pharmacist if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop. Some medicines and Estradot may interfere with each other. These include:
herbal medicines containing St. John's wort
some medicines to help you sleep, including barbiturates and meprobamate
some medicines for epilepsy, including phenytoin and carbamazepine
phenylbutazone, a medicine for pain and inflammation
some antibiotics and other anti-infective medicines, including rifampicin, rifabutin, nevirapine, efavirenz, ritonavir and nelfinavir
You may need to take different amounts of your medicines or to take different medicines while you are using Estradot. Your doctor and pharmacist have more information.If you have not told your doctor about any of these things, tell him/her before you start using this medicine.
How to use Estradot
Follow all directions given to you by your doctor and pharmacist carefully. These instructions may differ from the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
When to start it
If you are not already using HRT, you can start Estradot at a convenient time for you. If you are already using a different type of HRT, your doctor can advise you when to switch to Estradot.How much to use
Estradot patches come in five strengths. You will usually start with the Estradot 50 patch. Your doctor will check your progress and may change you to a lower or higher strength, depending on your response to treatment.How to use it
A leaflet in the carton contains pictures and information on how to apply the patch properly.You will have a patch on all the time. You will apply a new patch twice weekly (every 3 or 4 days). There are 8 patches in the carton, enough for a 4-week cycle.If you have not had a hysterectomy (operation to remove the uterus), you must take another type of hormone called a progestogen as well as using the patches. A progestogen helps to protect the lining of the uterus. If you have not been asked to take a progestogen, talk to your doctor.How long to use it
If you want to continue using HRT for longer than a few months, discuss the possible risks and benefits with your doctor. You may have an increased risk of developing breast cancer, heart disease, stroke, blood clots on the lungs and dementia. On the other hand, the risk of hip fractures and bowel cancer may be reduced. If you have had a hysterectomy but still have your ovaries, there may also be a small increase in the risk of developing cancer of the ovaries. Your doctor can discuss these risks and benefits with you, taking into account your particular circumstances.
If you forget to use it
Apply a new patch as soon as you remember, and then go back to your usual schedule.
If you have trouble remembering when to use or replace your patches, ask your pharmacist for some hints.
If you use too much (Overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) or go toAccident and Emergency at your nearest hospital, if you think that an overdose has happened. Keep the telephone numbers for these places handy.
Because of the way this medicine is used, an intentional overdose is unlikely. Swallowing a patch may cause nausea and vomiting.
While you are using Estradot
Things you must do
If you become pregnant while using Estradot, tell your doctor immediately. It should not be used while you are pregnant.

check your breasts and order a mammogram at regular intervals
check your uterus and cervix and do a pap smear at regular intervals
check 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.
Tell your doctor that you are using Estradot 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 as a result of an operation, serious injury or having to stay in bed for a prolonged period. If possible, this medicine should be stopped at least 4 weeks before surgery and it should not be restarted until you are fully mobile.
If you are about to have any blood tests, tell the person who takes the blood that you are using Estradot. It may interfere with the results of some tests.

After using Estradot
Keep your medicine in the original container until it is time to use it.
Store it in a cool dry place.
Do not store Estradot or any other medicine in the bathroom or near a sink.
Do not leave it in the car or on window sills.
Keep the patches where young children cannot reach them. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Fold used patches in half with the sticky side inwards. Dispose of them where children cannot reach them. Used patches still contain some oestradiol which could harm a child.
If your doctor tells you to stop using this medicine or the expiry date has passed, ask your pharmacist what to do with any patches that are left over.
