Chemical Name: ESTRADIOL (es-tra-DYE-ol)

Common uses
This medicine is an estrogen hormone used to provide female hormone when the body no longer produces enough. It is used to help reduce menopause symptoms (e.g., hot flashes, vaginal dryness), to prevent bone loss (osteoporosis) in people at high risk, and to treat other conditions as determined by your doctor. If you are only being treated for vaginal menopause symptoms, products applied locally such as vaginal creams, tablets, or rings should be considered before products taken by mouth or absorbed through the skin. There are several medicines (e.g., raloxifene or bisphosphonates) that are safe and effective to prevent or treat bone loss. These medicines should be considered for use before estrogen therapy. If you have other medical conditions as well and are prescribed estrogens for more than one condition, consult your doctor about your treatment plan and its options.

Before using
WARNING: Estrogens have been reported to increase the chance of womb cancer in women who have been through menopause, especially in women with a uterus who receive estrogen-only therapy. Estrogens may also increase the risk of cancer of the ovary or breast. Estrogen-containing medicines should not be used to prevent heart disease. Estrogen given in combination with another hormone called a progestin for replacement therapy can infrequently cause heart disease (including heart attacks), stroke, serious blood clots in the legs or lungs, dementia, and cancer of the breast. These risks appear to depend on the length of time this medicine is used and the amount of estrogen per dose. Therefore, this medicine should be used for the shortest possible length of time at the lowest effective dose so you obtain the benefits and minimize the chance of serious side effects from long-term treatment. Consult your doctor or pharmacist for details. If you use this medicine for an extended period of time, you should be evaluated at least once a year. This medicine must not be used during pregnancy because its use may result in birth defects or cancer later in the child's life. INFORM YOUR DOCTOR OR PHARMACIST of all prescription and over-the-counter medicine that you are taking. DO NOT START OR STOP any medicine without doctor or pharmacist approval. Inform your doctor of any other medical conditions including, a family medical history (especially breast lumps and cancer), asthma, diabetes, seizures, migraine headaches, heart disease (high blood pressure, heart attacks, congestive heart failure), kidney disease, low thyroid hormone, abnormal calcium level in the blood, depression, high blood pressure during pregnancy, yellowing of eyes or skin during pregnancy or with past estrogen use, womb problems (such as uterine fibroids or endometriosis), cholesterol or lipid problems, gallbladder disease, excessive weight gain, allergies, pregnancy, or breast-feeding. USE OF THIS MEDICINE IS NOT RECOMMENDED if you have a history of undiagnosed abnormal vaginal bleeding, certain cancers (such as breast or uterine cancer), blood clots, certain blood problems such as porphyria, liver disease, active/recent stroke, or heart attack. Contact your doctor or pharmacist if you have any questions or concerns about taking this medicine.
