Important Safety Information: Estradiol Capsules | Oral Estrogen Therapy
What is this?
This Important Safety Information summarizes key warnings and precautions for estradiol capsules, an oral estrogen therapy used to treat symptoms of menopause such as hot flashes, night sweats, vaginal dryness, and to prevent postmenopausal osteoporosis. Estradiol may also be used in certain cases of ovarian insufficiency or after surgical removal of the ovaries. This summary is based on pharmacy labeling information and does not include all available information. Always read your prescription label and follow your provider’s instructions.
Most Serious Warnings
Estradiol should not be used to prevent heart disease or dementia. Studies of estrogen, with or without progestin, have shown increased risks of:
Heart attack
Stroke
Blood clots
Breast cancer
