About estradiol tablets

This belongs to the group of medicines known as estrogens.

Estradiol is a naturally occurring form of estrogen, one of the female sex hormones. Estradiol is necessary for control of the menstrual cycle.

During the menopause, less and less estrogen is produced. Although the menopause is natural, the changes in estrogen level can give rise to distressing symptoms and problems. Estradiol provides the estrogen that your body has stopped producing. In addition, the loss of estrogen may, in some women, lead to thinning of the bones (osteoporosis) in later life. However, the use of estradiol to treat thinning of the bones is under review and other treatments for osteoporosis are usually tried first.

Estradiol is used as hormone replacement therapy (HRT) to treat symptoms due to the menopause and to prevent osteoporosis (thinning of the bones) in post-menopausal women who have had surgery to remove the uterus (womb).

Estradiol is also written as oestradiol, and estrogens as oestrogens. You may notice either spelling in use on packaging.

It is also sometimes known as: Premarin; Climaval; Progynova; Zumenon.. You may notice the use of any of these names on the packaging of your medicine.

How to take estradiol tablets

• If you do miss a dose, take it as soon as you remember and continue taking it at the usual times. If it is nearly time for your next dose, leave out the missed dose. Never take two doses to make up.
• This medicine is for you. Never give it to others, even if their condition appears to be the same as yours.
• Never take more than the prescribed dose. If you suspect that you or someone else has taken an overdose contact your doctor or go to the accident and emergency department of your local hospital at once. Always take the container with you even if it is empty.
• Before taking or using any 'over-the-counter' medicines, check with your pharmacist which medicines are safe for you to take.

Getting the most from your treatment

Benefits of HRT

• There are many benefits of hormone replacement therapy. Replacing the estrogen will stop some menopausal symptoms such as hot flushes, night sweats and vaginal dryness.
• HRT can dramatically reduce the development of osteoporosis and the likelihood of broken bones. During the menopause, a type of protein called collagen is lost from the skin. This makes the skin thinner and drier, HRT will help with these symptoms.
• If you are using HRT just for the prevention of thinning of the bones (osteoporosis) and are not suffering from menopausal symptoms you should make an early appointment with your doctor to review your treatment.
• If you are using HRT to relieve menopausal symptoms you should continue with your usual doctors' appointments and report any changes in your wellbeing and lifestyle, especially those below under the important section.

As with all medicines the benefits of HRT should be weighed against the problems that it may cause. Your doctor will discuss these problems with you and how they affect you individually. For short term treatment the benefits of HRT in treating menopausal symptoms may outweigh the problems. If used for a long time the incidence of breast cancer and other adverse effects may increase. Because of this the decision to start HRT needs to be made individually and progress of treatment should be reviewed at least once a year.
