Estrogen increases the risk that you will develop endometrial cancer (cancer of the lining of the uterus [womb]). The longer you take estrogen, the greater the risk that you will develop endometrial cancer. If you have not had a hysterectomy (surgery to remove the uterus), you should be given another medication called a progestin to take with estrogen. This may decrease your risk of developing endometrial cancer, but may increase your risk of developing certain other health problems, including breast cancer. Before you begin taking estrogen, tell your doctor if you have or have ever had cancer and if you have unusual vaginal bleeding. Call your doctor immediately if you have abnormal or unusual vaginal bleeding during your treatment with estrogen. Your doctor will watch you closely to help ensure you do not develop endometrial cancer during or after your treatment.
In a large study, women who took estrogen with progestins had a higher risk of heart attacks, strokes, blood clots in the lungs or legs, breast cancer, and dementia (loss of ability to think, learn, and understand). Women who take estrogen alone may also have a higher risk of developing these conditions. Tell your doctor if you smoke or use tobacco, if you have had a heart attack or a stroke in the past year, and if you or anyone in your family has or has ever had blood clots or breast cancer. Also tell your doctor if you have or have ever had high blood pressure, high blood levels of cholesterol or fats, diabetes, heart disease, lupus (a condition in which the body attacks its own tissues causing damage and swelling), breast lumps, or an abnormal mammogram (x-ray of the breast used to find breast cancer).
The following symptoms can be signs of the serious health conditions listed above. Call your doctor immediately if you experience any of the following symptoms while you are taking estrogen: sudden, severe headache; sudden, severe vomiting; speech problems; dizziness or faintness; sudden complete or partial loss of vision;double vision; weakness or numbness of an arm or a leg; crushing chest pain or chest heaviness; coughing up blood; sudden shortness of breath; difficulty thinking clearly, remembering, or learning new things; breast lumps or other breast changes; discharge from nipples; or pain, tenderness, or redness in one leg.
You can take steps to decrease the risk that you will develop a serious health problem while you are taking estrogen. Do not take estrogen alone or with a progestin to prevent heart disease, heart attacks, strokes, or dementia. Take the lowest dose of estrogen that controls your symptoms and only take estrogen as long as needed. Talk to your doctor every 3-6 months to decide if you should take a lower dose of estrogen or should stop taking the medication.
You should examine your breasts every month and have a mammogram and a breast exam performed by a doctor every year to help detect breast cancer as early as possible. Your doctor will tell you how to properly examine your breasts and whether you should have these exams more often than once a year because of your personal or family medical history.
Tell your doctor if you are having surgery or will be on bed rest. Your doctor may tell you to stop taking estrogen 4-6 weeks before the surgery or bed rest to decrease the risk that you will develop blood clots.
Talk to your doctor regularly about the risks and benefits of taking estrogen.
WHY is this medicine prescribed?
Estrogen is used to treat hot flushes ('hot flashes'; sudden strong feelings of heat and sweating) in women who are experiencing menopause ('change of life', the end of monthly menstrual periods). Some brands of estrogen are also used to treat vaginal dryness, itching, or burning, or to prevent osteoporosis (a condition in which the bones become thin and weak and break easily) in women who are experiencing or have experienced menopause. However, women who need a medication only to treat vaginal dryness or only to prevent osteoporosis should consider a different treatment. Some brands of estrogen are also to relieve symptoms of low estrogen in young women who do not produce enough estrogen naturally. Some brands of estrogen are also used to relieve the symptoms of certain types of breast and prostate (a male reproductive gland) cancer. Estrogen is in a class of medications called hormones. It works by replacing estrogen that is normally produced by the body.
HOW should this medicine be used?
Estrogen comes as a tablet to take by mouth. It is usually taken with or without food once a day. Estrogen is sometimes taken every day and sometimes taken according to a rotating schedule that alternates a period of time when estrogen is taken every day with a period of time when estrogen is not taken. When estrogen is used to relieve the symptoms of cancer, it is usually taken three times a day. Take estrogen at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take estrogen exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of estrogen and gradually increase your dose if your symptoms are still bothersome, or decrease your dose if your symptoms are well-controlled. Talk to your doctor about how well estrogen works for you.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
Are there OTHER USES for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
What SPECIAL PRECAUTIONS should I follow?

- tell your doctor and pharmacist if you are allergic to any brand of oral estrogen, any other estrogen products, any other medications, or any of the ingredients in estrogen tablets. If you will be taking Estrace® brand tablets, tell your doctor and pharmacist if you are allergic to aspirin or tartrazine (a food color additive). Ask your pharmacist or check the manufacturer's patient information for a list of the inactive ingredients in the brand of estrogen tablets you plan to take.
