Uses

INDICATIONS AND USAGE DEPO-Estradiol Injection is indicated in the treatment of: 1. Moderate to severe vasomotor symptoms associated with the menopause. 2. Hypoestrogenism due to hypogonadism.

Dosage

DOSAGE AND ADMINISTRATION Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Warming and shaking the vial should redissolve any crystals that may have formed during storage at temperatures lower than recommended. DEPO-Estradiol INJECTION IS FOR INTRAMUSCULAR USE ONLY. When estrogen is prescribed for a woman with a uterus, 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.

Warnings

WARNINGS 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. WARNINGS See BOXED WARNINGS 1. Cardiovascular disorders Estrogen and estrogen/progestin therapy have 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.
