Climaval (estradiol) is a form of estrogen, a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body. Climaval 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. Climaval is sometimes used as part of cancer treatment in women and men. Climaval may also be used for other purposes not listed in this medication guide.

The health and medical information provided here is for general purposes only and is not a substitute for the expertise and judgment of your physician, or other health care professional. It should not be understood to indicate that the use of this medicine is safe, appropriate or effective for you. Always consult your health care professional before using this, or any other, drug.

Climaval can harm an unborn baby or cause birth defects. Do not use Climaval if you are pregnant. You should not take Climaval 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 Climaval treatment may increase your risk of breast cancer, ovarian cancer, or uterine cancer. Talk with your doctor about your individual risks before using Climaval 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 Climaval 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 Climaval.
Climaval 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 Climaval.
