Consumer Medicine Information
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:
