Uses

INDICATIONS AND USAGE Menest is indicated in the: 1. Treatment of moderate to severe vasomotor symptoms associated with the menopause. 2. Treatment of moderate to severe symptoms of vulvar and vaginal atrophy associated with the menopause. When prescribing solely for the treatment of symptoms of vulvar and vaginal atrophy, topical vaginal products should be considered. 3. Female hypogonadism. 4. Female castration. 5. Primary ovarian failure. 6. Breast cancer (for palliation only) in appropriately selected women and men with metastatic disease. 7. Prostatic carcinoma - palliative therapy of advanced disease.

Dosage

DOSAGE AND ADMINISTRATION When estrogen is prescribed for a postmenopausal woman with a uterus, a progestin should also be initiated to reduce the risk of endometrial cancer. A woman without a uterus does not need progestin. Use of estrogen, alone or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman.

Side Effects

ADVERSE REACTIONS See Boxed Warnings , WARNINGS and PRECAUTIONS . The following additional adverse reactions have been reported with estrogens and/or progestin therapy. 1. Genitourinary system Changes in vaginal bleeding pattern and abnormal withdrawal bleeding or flow; breakthrough bleeding; spotting; dysmenorrhea, increase in size of uterine leiomyomata; vaginitis, including vaginal candidiasis; change in amount of cervical secretion; changes in cervical ectropion; ovarian cancer; endometrial hyperplasia; endometrial cancer; premenstrual like syndrome, amenorrhea during and after treatment; cystitis like syndrome. 2. Breasts Tenderness, enlargement, pain, nipple discharge, galactorrhea; fibrocystic breast changes; breast cancer. 3.

Warnings

ESTROGENS INCREASE THE RISK OF ENDOMETRIAL CANCERt 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. WARNINGS See Boxed Warnings . The use of unopposed estrogens in women who have a uterus is associated with an increased risk of endometrial cancer. 1. Cardiovascular disorders Estrogen and estrogen/progestin therapy has been associated with an increased risk of cardiovascular events such as myocardial infarction and stroke, as well as venous thrombosis and pulmonary embolism (venous thromboembolism or VTE). Should any of these occur or be suspected, estrogens should be discontinued immediately. Risk factors for arterial vascular disease (e.g., hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (e.g., personal history or family history of VTE, obesity, and systemic lupus erythematosus) should be managed appropriately. a. CONTRAINDICATIONS Menest should not be used in women with any of the following conditions: 1. Undiagnosed abnormal genital bleeding. 2. Known, suspected, or history of cancer of the breast except in appropriately selected patients being treated for metastatic disease. 3. Known or suspected estrogen-dependent neoplasia. 4.
