1. When I must not use FEMOSTON-CONTI?

Do not use FEMOSTON-CONTI 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 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.

Talk regularly with your doctor about whether you still need treatment with FEMOSTON-CONTI.

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

2. Why am I using FEMOSTON-CONTI?

FEMOSTON-CONTI contains the hormones estradiol and dydrogesterone. FEMOSTON-CONTI is a type of treatment called hormone replacement therapy (HRT).

FEMOSTON-CONTI 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-CONTI 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-CONTI 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.

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. 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.

3. What should I know before I use FEMOSTON-CONTI?


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.

Do not use FEMOSTON-CONTI if:

  • you have an allergy to any medicine containing estradiol or dydrogesterone, or any of the ingredients listed at the end of this leaflet
