Product description:
Estradiol is a sex hormone that is present in both males and females, and is the most important form of estrogen in humans. In women, it plays a key role in the development and functioning of the reproductive system, as well as in the growth of certain bones. It also governs the distribution of body fat in women and is the main hormone responsible for the fact that women are shorter than men, on average. Both the ovaries and the adrenal glands produce it.
The menstrual cycle in women involves predictable variations in the levels of several hormones, with estradiol being one of them. It is involved in the ovulation process and prepares the inner lining of the uterus for implantation, should the egg be fertilized. Certain tests done on baboons and other primates have indicated that his hormone also plays a continual role in maintaining a pregnancy, helping it to last for the full gestation period.
As a sex hormone, it also triggers many of the developments of the reproductive system that begin in puberty. It is present throughout the reproductive years, and declines during and after menopause. This decline is precisely what causes many of the symptoms of menopause, such as hot flashes and night sweats, vaginal dryness, and the loss of bone mass that may lead to osteoporosis.
Application:
Estradiol is used to treat symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation. Other uses include prevention of osteoporosis in postmenopausal women, and replacement of estrogen in women with ovarian failure or other conditions that cause a lack of natural estrogen in the body. Estradiol is sometimes used as part of cancer treatment in women and men.
These people should not use this drug:
You should not use this medicine if you are allergic to estradiol, if you are pregnant, or if you have:
1. unusual vaginal bleeding that a doctor has not checked;
2. liver disease;
3. a bleeding or blood-clotting disorder;
4. a recent history of heart attack or stroke;
5. a history of hormone-dependent cancer (such as breast, uterine, ovarian, or thyroid cancer);
6. if you have ever had a blood clot (especially in your lung or your lower body); or
7. if you are allergic to any medicines or food dyes.
Estradiol should not be used to prevent heart disease, stroke, or dementia, because this medicine may actually increase your risk of developing these conditions.
