Medical and Pharmacy Editor:
Estrogens can promote thickening of the lining of the uterus (endometrial hyperplasia) and increase the risk of uterine cancer. At diagnosis, endometrial cancers in recipients of estrogens are generally at an earlier stage and are less aggressive when they are discovered. Survival from endometrial cancer also is better in women taking estrogens than in those not taking estrogens. The addition of a progestin to estrogen therapy offsets the risk of endometrial cancer. Conflicting data exists on the association between estrogens and breast cancer. There may be a small increase in risk. The effect of concomitant progestin therapy on the risk of estrogen-induced breast cancer is unclear. Conjugated estrogens are well-absorbed from the vagina and into the blood. The amount absorbed depends on the frequency of use and the amount used. Thus, more frequent use or larger amounts of vaginal estrogens can have effects throughout the body (see conjugated estrogens, Premarin). The Women's Health Initiative found that postmenopausal women (50-79 years old) taking conjugated estrogens had an increased risk of breast cancer, blood clots, and stroke. There was also an increased risk of impaired cognition and/or dementia among women over age 65.
GENERIC AVAILABLE: No
PREPARATIONS: 0.625 mg/gram
STORAGE: The cream should be stored at room temperature, 15-30 C (59-86 F).
DOSING: The recommended dose is 0.5 to 2 grams administered daily for 21 days then off for 7 days. Twice weekly administration may also be used. Vaginal products work best if used at bedtime. The hands should first be washed and the applicator filled with cream from the tube. Lying on the back with the knees bent, individuals should insert the applicator into the vagina and push the applicator's plunger to deliver the cream. The applicator and plunger then should be washed with warm, soapy water and rinsed with plain water. The hands should be washed before and after use. A small amount of the cream also can be applied to the outer skin folds or "lips" of the vagina (vulvae) to relieve dryness or irritation.
