Estradiol is a type of estrogen, a female sex hormone produced by the ovaries. It is required for several processes in the body. When it is not produced in sufficient quantities in the body (for example: in postmenopausal women), then it has to be taken in the form of medication. Estradiol is sold as medication under various trade names, some of which are Estrace, Climara and Climara Forte (made by Bayer Schering Pharma), Vagifem (Novo - Nordisk, Denmark), E2 (Sun Pharma), Progynon Depot (made by Cadila Healthcare), and Progynova (German Remedies (India)). This medication is available in several forms such as tablets, vaginal cream, vaginal tabs, injections and skin patches.
Estradiol is prescribed primarily for the treatment of menopausal symptoms like hot flashes, vaginal dryness, burning, and irritation. Some of its other uses are prevention of osteoporosis in postmenopausal women, and replacement of estrogen in women with ovarian failure or other disorders that result in deficiency of natural estrogen in the body. Estradiol medication is also used for the treatment of some types of cancer in women and men.
Estradiol may also be used for conditions not mentioned here in this guide.
Important Information about Estradiol
Taking Estradiol (Estrace, Climara, Climara Forte, Vagifem, E2, Progynon Depot, Progynova) for a long time may increase the risk of breast, ovarian, or uterine cancer. Discuss this with your doctor about your specific risks. You may be required to have regular physical checkups and mammograms while taking this medication. Do not forget to also self examine your breasts regularly for lumps. You may be monitored for your progress and condition every 3 to 6 months to ensure that Estradiol is functioning properly in you. Taking progestin while taking estradiol may decrease your risk of uterine cancer. If you have not had a hysterectomy (uterus removal surgery), you may be prescribed progestin along with estradiol.
Do not take estradiol if you have unusual and abnormal vaginal bleeding, liver disease, breast or uterine cancer, hormone related cancer, an incident of heart attack or stroke in the recent past, if you are allergic to it, if you are pregnant, or if you have ever had a blood clot. Hormonal medications can increase risk of blood clots, stroke, or a heart attack, especially if you are suffering from diabetes, high blood pressure, high cholesterol or triglycerides, if you are overweight, or if you smoke.
Estradiol is classified as FDA pregnancy category X drug which means this medication can harm an unborn baby or cause birth defects in the newborn if the mother takes it during her pregnancy. Estradiol is strictly not recommended for pregnant women. Notify your doctor in advance if you are pregnant or become pregnant while taking estradiol. Estradiol can pass into breast milk and harm a nursing baby. It may also slow breast milk production. Hence this medication is also not recommended if you are breast feeding.
Before taking Estradiol
Before taking Estradiol (Estrace, Climara, Climara Forte, Vagifem, Progynon Depot, Progynova), take all precautions as mentioned above and discuss about them and all points mentioned above with your doctor. Inform your doctor in advance if you have any of these conditions: lupus, porphyria, endometriosis, gallbladder disease, hypothyroidism, asthma, migraines, epilepsy, calcium deficiency, or if you have had a hysterectomy. Your doctor will decide if it is safe for you to take estradiol on top of these conditions.

You may be prescribed a course of progestin along with estradiol. Always follow your doctor’s directions and advice.
What if I miss a dose?
If you forget to take a dose of estradiol for some reasons, take it as soon as you remember it. However, skip the missed dose if the time to take the next dose is almost up or near. Do not take two doses closer to each other to make up for the missed dose.
