Boxed Warning

ESTROGENS INCREASE THE RISK OF ENDOMETRIAL CANCER

Close clinical surveillance of all women taking estrogens is important. Adequate diagnostic measures, including endometrial sampling when indicated, should be undertaken to rule out malignancy in all cases of undiagnosed persistent or recurring abnormal vaginal bleeding. There is no evidence that the use of “natural” estrogens results in a different endometrial risk profile than synthetic estrogens at equivalent estrogen doses. (See WARNINGS, Malignant Neoplasms, Endometrial Cancer.)

CARDIOVASCULAR AND OTHER RISKS

Estrogens with or without progestins should not be used for the prevention of cardiovascular disease. (See WARNINGS, Cardiovascular Disorders.)

The Women’s Health Initiative (WHI) study reported increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) during 5 years of treatment with oral conjugated estrogens (CE 0.625 mg) combined with medroxyprogesterone acetate (MPA 2.5 mg) relative to placebo. (See CLINICAL PHARMACOLOGY, Clinical Studies.)

The Women’s Health Initiative Memory Study (WHIMS), a substudy of WHI, reported increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with oral conjugated estrogens plus medroxyprogesterone acetate relative to placebo. It is unknown whether this finding applies to younger postmenopausal women or to women taking estrogen alone therapy. (See CLINICAL PHARMACOLOGY, Clinical Studies.)

Other doses of oral conjugated estrogens with medroxyprogesterone acetate, and other combinations and dosage forms of estrogens and progestins were not studied in the WHI clinical trials and, in the absence of comparable data, these risks should be assumed to be similar. Because of these risks, estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

H.S. and read what you get each time you refill Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT ESTERIFIED ESTROGENS AND METHYLTESTOSTERONE TABLETS AND ESTERIFIED ESTROGENS AND METHYLTESTOSTERONE TABLETS H.S. (A COMBINATION OF ESTROGEN AND ANDROGEN HORMONES)?

• 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 Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S.

What are Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S.?

Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S. are medicines that contain estrogen and androgen hormones.

What are Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S. used for?

Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S. are used after menopause to:

• reduce moderate to severe hot flashes. Estrogens are hormones made by a woman’s ovaries. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. This drop in body estrogen levels 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 Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S.

• treat moderate to severe dryness, itching, and burning in and around the vagina. You and your healthcare provider should talk regularly about whether you still need treatment with Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S. to control these problems. If you use Esterified Estrogens and Methyltestosterone Tablets and Esterified Estrogens and Methyltestosterone Tablets H.S. only to treat your dryness, itching, and burning in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you.
