What is in this leaflet

This leaflet answers some of the common questions about Duphaston.

It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have benefits and risks. Your doctor has weighed the risks of you taking Duphaston against the benefits they expect it will have for you. If you have any concerns about using this medicine, ask your doctor or pharmacist.

If you would like more information ask your doctor.

Keep this leaflet with your medicine. You may need to read it again. When you must not use Duphaston Do not use 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 medoxyprogesterone 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 Duphaston.

Treatment with oestrogens, with or without progestogens should be used at the lowest effective dose and for the shortest period of time. What Duphaston is used for Duphaston treats conditions where there is a lack of the female hormone progesterone. It is used for:
restoring bleeding in the absence of menstrual periods
controlling irregular bleeding which is due to hormonal imbalance
the treatment of endometriosis, which is a disease where fragments of the lining of the womb grow outside the womb in the pelvic cavity
painful periods which do not have any specific cause such as fibroids or infection
a supplement for menopausal women who are taking hormone replacement therapy (HRT), in which it helps to protect the womb.

Duphaston is an artificial hormone similar to human progesterone. It belongs to a group of hormones called progestogens. Duphaston has been approved for the uses listed above. However, your doctor may prescribe this medicine for another use. Ask your doctor for further information. Duphaston is not addictive. Before you take Duphaston When you must not take it

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

The decision to use HRT should be based on your particular needs and health, and made after a careful medical evaluation. Do not take Duphaston:
if you have any blood clotting problems, or have had a stroke or a heart attack
if you have liver or gall bladder disease
if you have ever had jaundice (yellowing of the skin or eyes), which can occur with an intense generalised itching during pregnancy, or run in families
if you have, or are suspected to have, cancer of the breast or genitals, or some form of oestrogen (female hormone) dependent cancer
if you have had liver cancer due to taking oral contraceptives
if you have unusual vaginal bleeding that has not been seen by a doctor
if you know you have abnormal red blood cells (sickle cell anaemia)
if you are pregnant, or are planning to become pregnant.

Duphaston may affect your developing baby if you take it during pregnancy
if you have ever had herpes during pregnancy
if you have had a certain type of miscarriage known as missed abortion
if you are breastfeeding.

Duphaston passes into breast milk and therefore there is a possibility that the breast-fed baby may be affected
if you know you are allergic to Duphaston or any of its ingredients.

Your doctor will advise you whether you should take Duphaston tablets. If you have not told your doctor about any of the above, tell them before you start taking Duphaston.

Your doctor will give you a thorough examination prior to prescribing this medicine and will give you further examinations regularly during treatment. Your doctor is likely to check your blood pressure, breasts, tummy, and do a Pap smear test. Special Warning

Although not reported with the use of Duphaston tablets, users of other progestogens (contained in oral contraceptives) may be exposed to an increased risk of a number of serious conditions. These include blood clots, stroke, heart attack, liver tumours, gall bladder disease and high blood pressure. Ask your doctor about the risks involved with taking progestogens for a long time.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.

When to take it

If you forget to take Duphaston

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

Do not take a double dose to make up for the one you missed.
