What is Estrace?
Estrace (estradiol) is a form of estrogen, a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body.
Estrace 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. Estrace is sometimes used as part of cancer treatment in women and men.
Estrace may also be used for other purposes not listed in this medication guide.
You should not use Estrace if you have: liver disease, a bleeding disorder, unusual vaginal bleeding, history of a hormone-dependent cancer (such as breast, uterine, ovarian, or thyroid cancer), or if you have ever had a heart attack, stroke, or a blood clot.
Do not use if you are pregnant.
Estrace may increase your risk of developing a condition that may lead to uterine cancer. Call your doctor at once if you have any unusual vaginal bleeding while using this medicine.
Estrace should not be used to prevent heart disease, stroke, or dementia, because this medicine may actually increase your risk of developing these conditions. Long-term use may also increase your risk of breast cancer or blood clot.
Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment.
Estradiol can harm an unborn baby or cause birth defects. Do not use estradiol if you are pregnant. You should not take Estrace if you have abnormal vaginal bleeding, liver disease, breast or uterine cancer, hormone-dependent cancer, a recent history of heart attack or stroke, if you are pregnant, if you have ever had a blood clot (especially in your lung or your lower body), or if you are allergic to any medicines or food dyes. Taking hormones can increase your risk of blood clots, stroke, or heart attack, especially if you have diabetes, high blood pressure, high cholesterol or triglycerides, if you smoke, or if you are overweight.
Have regular physical exams and mammograms, and self-examine your breasts for lumps on a monthly basis while using Estrace.
