estradiol oral

What is the most important information I should know about estradiol oral?

Estradiol can harm an unborn baby or cause birth defects. Do not use estradiol if you are pregnant.

You should not take estradiol 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.

Long-term estradiol treatment may increase your risk of breast cancer, ovarian cancer, or uterine cancer. Talk with your doctor about your individual risks before using estradiol long-term. Your doctor should check your progress every 3 to 6 months to determine whether you should continue this treatment.

Taking progestin while using estradiol may lower your risk of uterine cancer. If your uterus has not been removed, your doctor may prescribe a progestin for you to take while you are using estradiol.

Estradiol should not be used to prevent heart disease, stroke, or dementia, because this medication may actually increase your risk of developing these conditions.

Have regular physical exams and mammograms, and self-examine your breasts for lumps on a monthly basis while using estradiol.

What is estradiol oral?

Estradiol is a form of estrogen, a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body.

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.

Estradiol may also be used for other purposes not listed in this medication guide.
