When estrogen is prescribed for a postmenopausal 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. Patients should be reevaluated periodically as clinically appropriate (e.g., 3-month to 6-month intervals) to determine if treatment is still necessary (See BOXED WARNINGS and WARNINGS). For women who have a uterus, adequate diagnostic measures, such as endometrial sampling, when indicated, should be undertaken to rule out malignancy in cases of undiagnosed persistent or recurring abnormal vaginal bleeding.

Care should be taken to inject deeply into the upper, outer quadrant of the gluteal muscle following the usual precautions for intramuscular administration. By virtue of the low viscosity of the vehicles, the various preparations of DELESTROGEN (estradiol valerate injection, USP) may be administered with a small gauge needle (i.e., 20 Gauge × 1 ½ inches long). Since the 40 mg potency provides a high concentration in a small volume, particular care should be observed to administer the full dose.

DELESTROGEN should be visually inspected for particulate matter and color prior to administration; the solution is clear, colorless to pale yellow. Storage at low temperatures may result in the separation of some crystalline material which redissolves readily on warming.

Note: A dry needle and syringe should be used. Use of a wet needle or syringe may cause the solution to become cloudy; however, this does not affect the potency of the material.

Patients should be started at the lowest dose for the indication. The lowest effective dose of DELESTROGEN has not been determined for any indication. Treated patients with an intact uterus should be monitored closely for signs of endometrial cancer, and appropriate diagnostic measures should be taken to rule out malignancy in the event of persistent or recurring abnormal vaginal bleeding. See PRECAUTIONS concerning addition of a progestin.

For treatment of moderate to severe vasomotor symptoms, vulvar and vaginal atrophy associated with the menopause, the lowest dose and regimen that will control symptoms should be chosen and medication should be discontinued as promptly as possible.
The usual dosage is 10 to 20 mg DELESTROGEN every four weeks.
Attempts to discontinue or taper medication should be made at 3-month to 6-month intervals.
For treatment of female hypoestrogenism due to hypogonadism, castration, or primary ovarian failure.
The usual dosage is 10 to 20 mg DELESTROGEN every four weeks.
For treatment of advanced androgen-dependent carcinoma of the prostate, for palliation only.
The usual dosage is 30 mg or more administered every one or two weeks.
