Delestrogen (Estradiol Valerate) - Summary



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).


Estrogens and 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.

Delestrogen review by 63 year old female patient

Overall rating:  
Effectiveness:   Moderately Effective
Side effects:   No Side Effects
Treatment Info
Condition / reason:   total hysterectomy
Dosage & duration:   .5 mg taken daily for the period of 20 years
Other conditions:   P.A.T.
Other drugs taken:   metoprolot 25 mg
Reported Results
Benefits:   Keeping me from the effects of menopause.
Side effects:   I believe the benefits were to keep my skin soft, prevent sagging and wrinkles
Comments:   I was prescribed estrogen at the time of my total hysterectomy (due to increasing bleeding and starting periods every 2 weeks). I was becoming anemic from the bleeding and other procedures to stop this were not very successful. I was about 45 at the time and was given the option to begin HRT. Over the years I have been given decreasing levels and am currently at .5mg. Even with the negative info regarding prolonged HRT, I opted to continue. If you actually read the negative information, it was not related to estrogen, but rather to estrogen and progesterone in combination. Since then more articles have further clarified some of the mis-information. It may be a risk to continue long term HRT, but none of my doctors has really presented any solid reasoning to discontinue HRT.
