About this medication
- Estradiol is a hormone replacement medicine used to relieve menopause symptoms such as hot flushes, and vaginal dryness, itching, or burning.
- Estradiol can also help prevent thinning of the bones (osteoporosis) after menopause, alongside a healthy diet, calcium and vitamin D, not smoking, and regular exercise.
Relieves menopausal symptoms in appropriately assessed patients.
How to use it
- Take this medicine exactly as your healthcare professional tells you. The amount and how often you take it will be on your prescription label.
- Swallow the tablet with water, with or without food, at about the same time every day.
- If you still have your uterus, you may be told to take estradiol only on certain days of the month, along with a progestin on other days. Follow your healthcare professional's instructions closely.
- If you have had your uterus removed, you will usually take estradiol every day of the month.
If you miss a dose
- Take the missed dose as soon as you remember.
- If it is almost time for your next dose, skip the missed dose and continue your regular schedule.
- Do not take two doses at the same time.
Use the lowest effective prescribed regimen with periodic review. An intact uterus usually requires endometrial protection with a progestogen.
Pregnancy and breastfeeding
- Do not take estradiol if you are pregnant or think you might be pregnant.
- Do not take estradiol while breastfeeding.
Do not use during pregnancy or breastfeeding; not contraception.
Before you use it
- Do not take estradiol if you have or have had breast cancer, cancer of the uterus, unexplained vaginal bleeding, or blood clots.
- Do not take estradiol if you have liver disease or migraines with aura (classical migraine).
- Do not take estradiol if you are pregnant or breastfeeding.
- Tell your healthcare professional if you have high blood pressure, high cholesterol, diabetes, gallbladder disease, epilepsy, asthma, or kidney disease.
- Tell your healthcare professional if you smoke, or if you or a close family member has had blood clots.
- Tell your healthcare professional if you still have your uterus, since you will likely also need a second hormone, called a progestin, to protect your uterus.
Important warnings
- Taking estrogen together with a progestin increases the risk of breast cancer, heart attack, stroke, and blood clots in the lungs or large veins.
- Taking estrogen alone increases the risk of stroke and blood clots in large veins.
- Estrogen should not be used to prevent heart disease or stroke.
- If you still have your uterus and take estrogen without a progestin, you have a higher risk of overgrowth of the lining of the uterus and uterine cancer.
- Women 65 and older who take estrogen with a progestin may have a higher risk of memory problems.
- Estradiol should be used at the lowest dose that works, for the shortest time needed.
Avoid unexplained bleeding, relevant cancers, liver disease and previous arterial or venous clots.
