Note the following important information about estrogen replacement therapy: The Women's Health Initiative (WHI) study results indicated an increased risk of heart attack, stroke, Breast Cancer, blood clots in the lungs, and blood clots in the leg veins in postmenopausal women during 5 years of treatment with 0.625 mg conjugated equine estrogens and 2.5 mg medroxyprogesterone compared to women receiving sugar tablets. Other combinations of estrogen and progestins were not studied. However, until additional data are available, the risks should be assumed to be similar for other hormone replacement products. Therefore,

• estrogen with or without progestins should be used at the lowest dose that relieves your menopausal symptoms for the shortest time period possible, as directed by your doctor.
• estrogen with or without progestins should not be used to prevent heart disease, heart attacks, or strokes.

Blood clots: Estrogen with or without progestins is associated with an increased risk of blood clots in the lungs and legs. This risk also increases with age, a personal or family history of blood clots, smoking, and Obesity. The risk of blood clots is also increased if you are immobilized for prolonged periods and with major surgery. If possible, Estrogens-Vaginal (Estrogens-vaginal) should be stopped 4 to 6 weeks before major surgery. Talk about the risk of blood clots with your doctor.

Breast cancer: Some studies have found an association between a modest increase in the risk of developing breast cancer and the use of hormone replacement therapy after menopause. Women who have a history of breast cancer should not use estrogens. If you have a family history of breast cancer, breast nodules, fibrocystic disease of the breast, or abnormal mammograms, you should be closely monitored by your doctor if you use estrogens. Women using estrogens should have regular breast examinations and should be taught how to do a breast self-examination. Your doctor may also recommend regular mammograms, depending on your age, risk factors, and previous mammogram results. Estrogens-Vaginal (Estrogens-vaginal) must not be applied to the breasts, as it may have harmful effects on the breast tissue. Discuss the benefits and risks with your doctor so that you can make an informed choice about using Estrogens-Vaginal (Estrogens-vaginal).

Condoms, diaphragms, or cervical caps: Estrone vaginal cream contains mineral oil, which may weaken the latex rubber of condoms, diaphragms, and cervical caps. Therefore, they may not be effective in preventing pregnancy for women who use the cream.

Dementia: Women over age 65 receiving combined estrogen and progestin replacement therapy may be at increased risk of developing dementia (loss of memory and intellectual function). If you are over 65 years of age, your doctor should closely monitor you for loss of memory and intellectual function.

Diabetes: People with diabetes should monitor their blood glucose closely to detect any changes in blood glucose control that sometimes occurs with use of estrogens. If you have risk factors for diabetes, your doctor will monitor your blood glucose regularly while you are on Estrogens-Vaginal (Estrogens-vaginal).

Endometrial cancer: Several studies suggest that estrogen replacement therapy increases the risk of cancer of the endometrium (uterus). Taking a progestin along with the estrogen reduces the risk to the same level as that of a woman not using estrogens. For this reason, all women who have not had their uterus removed should also take a progestin if they are using estrogens.

Fibroids: Estrogens-Vaginal (Estrogens-vaginal) may worsen fibroids, causing sudden enlargement, pain, or tenderness. If you notice these effects, contact your doctor.

Gallbladder: An increased risk of gallbladder disease has been reported by postmenopausal women who take oral estrogens. If you experience symptoms of a gallbladder attack, such as severe pain on the right side of the abdomen, nausea, vomiting, and Fever, contact your doctor as soon as possible. If you have a history of gallbladder problems, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed.

Heart disease and stroke: Studies indicate an increased risk of heart disease and stroke with estrogen (with or without progestins) for postmenopausal women. Get immediate medical attention if you experience symptoms of a heart attack (chest pain, tightness or pressure, sweating, nausea, feeling of impending doom) or stroke (sudden dizziness, headache, loss of speech, changes in vision, weakness or numbness in the arms and legs) while taking Estrogens-Vaginal (Estrogens-vaginal).

High Cholesterol or triglycerides: Estrogen may increase triglyceride (a type of fat found in the blood) levels, especially in those who already have high levels of triglycerides. If you have high levels of cholesterol or triglycerides, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed. Your doctor may want to test your liver function (the liver makes cholesterol and triglycerides) regularly with blood tests while you are taking Estrogens-Vaginal (Estrogens-vaginal).

Liver disease: Estrogens may reduce liver function and can cause liver failure. If you have liver problems, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking Estrogens-Vaginal (Estrogens-vaginal).

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Ovarian Cancer: Several studies suggest that estrogen replacement therapy increases the risk of cancer of the ovaries, especially when taken for 5 years or longer. This may occur whether you are taking a progestin or not. If you are at an increased risk of developing ovarian cancer, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your risk, whether any special monitoring is needed, and whether Estrogens-Vaginal (Estrogens-vaginal) is appropriate for you.

Porphyria: Estrone vaginal cream may worsen symptoms of porphyria. If you have porphyria, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed.

Seizures: Estrogens may cause an increase in the frequency of seizures for women who experience seizures or have a history of seizures. If you have a history of seizures, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed.

Thyroid disease: Estrogens can affect how well the thyroid gland works. If you have thyroid disease such as Hypothyroidism (low thyroid levels), discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed.

Water retention: Estrogen may cause sodium (salt) and water retention, making symptoms worse for people with certain medical conditions such as Epilepsy, Asthma, and kidney or heart dysfunction. If you have any of these medical conditions, discuss with your doctor how Estrogens-Vaginal (Estrogens-vaginal) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Estrogens-Vaginal (Estrogens-vaginal), and whether any special monitoring is needed.

Pregnancy: Estrogen should not be used during pregnancy. If you become pregnant while using Estrogens-Vaginal (Estrogens-vaginal), contact your doctor immediately.

Estrogen is a hormone that is produced by the ovaries. Once Menopause is reached, the ovaries produce less estrogen and symptoms of menopause can occur. Estrone vaginal cream works by providing locally acting estrogen.
