Warning
Estrogens, either used alone or with another hormone (progestin), have rarely caused very serious side effects. Discuss the risks and benefits of hormone treatment with your doctor. Estrogens should not be used to prevent heart disease or dementia.Estrogens can increase the risk of cancer of the uterus (endometrial cancer). Taking a progestin as directed by your doctor can help decrease this risk. Tell your doctor right away if you have any unusual vaginal bleeding.In postmenopausal women, estrogens can increase the risk of cancer of the ovaries, stroke, dementia, and serious blood clots in the legs. Estrogens alone do not appear to increase the risk of breast cancer when used for up to 7 years. Estrogen, when used with a progestin, can increase the risk of heart disease (such as heart attacks), stroke, serious blood clots in the lungs/legs, dementia, and cancer of the breast/ovaries.The risk for serious side effects may depend on the dose of estrogen and the length of time it is used. Therefore, this medication should be used at the lowest effective dose and for the shortest amount of time. Discuss the use of this medication with your doctor and check with him/her regularly (for example, every 3 to 6 months) to see if you still need to use this medication. If you will be using this medication long-term, you should have regular complete physical exams (for example, once a year) as directed by your doctor. See also Notes section.

Uses
This medication is a female hormone (estrogen). It is used by women to help reduce symptoms of menopause (such as hot flashes, vaginal dryness). These symptoms are caused by the body making less estrogen. If you are using this medication to treat symptoms only in and around the vagina, products applied directly inside the vagina should be considered before medications that are taken by mouth, absorbed through the skin, or injected. This medication may also be used by women who are not able to produce enough estrogen (for example, due to hypogonadism, primary ovarian failure).Certain estrogen products may also be used by women after menopause to prevent bone loss (osteoporosis). However, there are other medications (such as raloxifene, bisphosphonates including alendronate) that are also effective in preventing bone loss and may be safer. These medications should be considered for use before estrogen treatment.
