Estradiol (medication)
(Redirected from Estrofem)
What is Estradiol (medication)?[edit | edit source]
- Estradiol (E2) Estradiol is a medicine that contains estrogen hormones.
- It is an estrogen and is used mainly in menopausal hormone therapy and to treat low sex hormone levels in women.
- It is also used in hormonal birth control for women, in hormone therapy for transgender women, and in the treatment of hormone-sensitive cancers like prostate cancer in men and breast cancer in women, among other uses.
- Estradiol can be taken by mouth, held and dissolved under the tongue, as a gel or patch that is applied to the skin, in through the vagina, by injection into muscle or fat, or through the use of an implant that is placed into fat, among other routes.
What are the uses of this medicine?[edit | edit source]
Estradiol (E2), is used to:
- reduce moderate to severe hot flashes
- treat dryness, itching, and burning in or around the vagina, difficulty or burning on urination associated with menopause
- treat certain conditions in which a young woman's ovaries do not produce enough estrogen naturally
- treat certain types of abnormal vaginal bleeding due to hormonal imbalance when your doctor has found no serious cause of the bleeding
- treat certain cancers in special situations, in men and women
- prevent thinning of bones (Osteoporosis from menopause)
How does this medicine work?[edit | edit source]
- Estrogens are hormones made by a woman's ovaries.
- Between ages 45 and 55, the ovaries normally stop making [[]]estrogens.
- This leads to a drop in body estrogen levels which causes the “change of life” or menopause (the end of monthly menstrual periods).
- Sometimes, both ovaries are removed during an operation before natural menopause takes place.
- The sudden drop in estrogen levels causes “surgical menopause”.
- When the estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating (“hot flashes” or “hot flushes”).
- In some women, the symptoms are mild, and they will not need estrogens.
- In other women, symptoms can be more severe.
- You and your healthcare provider should talk regularly about whether you still need treatment with estradiol.

What special precautions should I follow?[edit | edit source]
- Estrogens increase the chances of getting cancer of the uterus. Report any unusual vaginal bleeding right away while you are taking estrogens. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.
- Do not use estrogens with or without progestins to prevent heart disease, heart attacks, or strokes. Using estrogens with or without progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots. Using estrogens with progestins may increase your risk of dementia. You and your healthcare provider should talk regularly about whether you still need treatment with estradiol tablets.
- Have a breast exam and mammogram (breast x-ray) every year unless your healthcare provider tells you something else. If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram (breast x-ray), you may need to have more frequent breast examinations.
- If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or if you use tobacco, you may have higher chances for getting heart disease. Ask your healthcare provider for ways to lower your chances for getting heart disease.
- Talk with your healthcare provider regularly about whether you should continue taking estradiol tablets. You and your doctor should reevaluate whether or not you still need estrogens at least every six months.
- In a small number of case reports, substantial increases in blood pressure have been attributed to idiosyncratic reactions to estrogens. Blood pressure should be monitored at regular intervals with estrogen use.
- In patients with pre-existing hypertriglyceridemia, estrogen therapy may be associated with elevations of plasma triglycerides leading to pancreatitis and other complications.
- Estrogen administration leads to increased thyroid-binding globulin (TBG) levels. Patients dependent on thyroid hormone replacement therapy who are also receiving estrogens may require increased doses of their thyroid replacement therapy.
- Estrogens should be used with caution in individuals with severe hypocalcemia.
- Endometriosis may be exacerbated with administration of estrogens.
- Estrogens may cause an exacerbation of asthma, diabetes mellitus, epilepsy, migraine or porphyria, systemic lupus erythematosus, and hepatic hemangiomas and should be used with caution in women with these conditions.
- Estrogen administration to nursing mothers has been shown to decrease the quantity and quality of the milk. Caution should be exercised when estradiol is administered to a nursing woman.
