Step 7. Remove the applicator. (It is normal for a small amount of gel to be left in the applicator. You will still get the right dose of medicine.)
Keep the applicator clean and germ free for later use.
Vaginal cream or tablet
Use the applicator provided with drug to insert vaginal tablet or measure dose of vaginal cream
Lay on back with pelvis slightly tilted upward, or stand with one knee bent (ie, foot on seat of chair or toilet), insert the prescribed dose with the applicator
The applicator should be inserted (without forcing) as far as comfortably possible, or until half of the applicator is inside vagina
Note: The vaginal tablet dissolves gradually over several hours, so bedtime application may be desired
Contra Indications
Undiagnosed abnormal genital bleeding
Known, suspected, or history of breast cancer
Known or suspected estrogen-dependent neoplasia
Active DVT, PE, or history of these conditions
Active arterial thromboembolic disease (eg, stroke, MI), or a history of these conditions
Known anaphylactic reaction or angioedema to estrogen
Known liver impairment or disease
Known protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders
Known or suspected pregnancy
Precautions
Increased risk of endometrial cancer
Close clinical surveillance of all women taking estrogens is important
Risk of endometrial cancer in women with a uterus increases with use of unopposed estrogens; adding progestin to estrogen therapy may reduce risk of endometrial hyperplasia, a precursor to endometrial cancer
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
Breast cancer
The WHI estrogen plus progestin substudy also demonstrated an increased risk of invasive breast cancer; prescribe estrogens with or without progestins at the lowest doses and for the shortest duration
System absorption occurs with intravaginal administration; consider warnings, precautions, and adverse effects associated with systemic estrogen-alone therapy
Increased risk of stroke and DVT reported with estrogen-alone therapy; increased risk of PE, DVT, stroke, and MI reported with estrogen plus progestin therapy; discontinue drug immediately if these conditions occur or are suspected
The WHI estrogen plus progestin substudy reported a statistically nonsignificant increased risk of ovarian cancer (4 vs 3 cases per 10,000 women-years)
Estrogen with or without progesterone may increase risk of dementia
Increased risk of gallbladder disease (2- to 4-fold) requiring surgery in postmenopausal women receiving estrogen has been reported
Severe hypercalcemia in women with breast cancer and bone metastases reported with estrogen use; if hypercalcemia occurs, discontinue estrogen and initiate appropriate treatment to reduce serum calcium level
Retinal vascular thrombosis reported; discontinue estrogen pending examination if there is a sudden partial or complete loss of vision, or a sudden onset of proptosis, diplopia, or migraine; if papilledema or retinal vascular lesions diagnosed, permanently discontinue estrogens
Rare occurrences reported of substantial blood pressure increases that were attributed to idiosyncratic reactions to estrogens
May cause elevated triglycerides that lead to pancreatitis in women with preexisting hypertriglyceridemia; discontinue estrogens if pancreatitis occurs
Estrogens may be poorly metabolized with hepatic impairment; if cholestatic jaundice occurs, discontinue estrogens; exercise caution in any woman with a history of cholestatic jaundice associated with past estrogen use or with pregnancy
Estrogen administration leads to increased thyroid-binding globulin (TBG) levels; women with normal thyroid function can compensate for the increased TBG by making more thyroid hormone, thus maintaining free T4 and T3 serum concentrations in the normal range, however, women dependent on thyroid hormone replacement therapy who are also receiving estrogens may require increased doses of their thyroid replacement therapy; monitor thyroid function in these women during treatment to maintain their free thyroid hormone levels in an acceptable range
Estrogens may cause some degree of fluid retention; women with conditions that might be influenced by this factor (eg, cardiac or renal impairment) warrant careful observation; monitor any woman with a condition(s) that might predispose her to fluid retention, such as cardiac or renal impairment; discontinue estrogen-alone therapy with evidence of medically concerning fluid retention
Malignant transformation of residual endometrial implants have been reported in women treated post-hysterectomy with estrogen-alone therapy; if residual endometriosis post-hysterectomy exists, the addition of progestin should be considered
Exogenous estrogens may exacerbate symptoms of angioedema in women with hereditary angioedema; consider whether benefits of estrogen therapy outweigh risks in such women
Estrogen therapy may exacerbate asthma, diabetes mellitus, epilepsy, migraine, porphyria, systemic lupus erythematosus, and hepatic hemangiomas; consider whether benefits of estrogen therapy outweigh risks in women with these conditions
Local abrasion induced by vaginal tablet applicator reported
Serum follicle stimulating hormone (FSH) and estradiol levels not shown for the management of moderate to severe symptoms of vulvar and vaginal atrophy due to menopause
Accelerated prothrombin time, partial thromboplastin time, and platelet aggregation time; increased platelet count; increased factors II, VII antigen, VIII antigen, VIII coagulant activity, IX, X, XII, VII-X complex, II-VII-X complex, and beta-thromboglobulin; decreased levels of antifactor and antithrombin III, decreased antithrombin III activity; increased levels of fibrinogen and fibrinogen activity; increased plasminogen antigen and activity
Estrogen-induced hypocalcemia may occur in women with hypoparathyroidism; consider whether benefits of estrogen therapy outweigh risks in such women
Pregnancy-Lactation
Pregnancy
Not indicated for use in pregnancy; there are no data with use in pregnant women; however, epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to combined hormonal contraceptives (estrogens and progestins) before conception or during early pregnancy
Lactation
Estrogens are present in human milk and can reduce milk production in breast-feeding females; this reduction can occur at any time but is less likely to occur once breastfeeding is well-established; the clinical need for therapy and any potential adverse effects on breastfed child or from underlying maternal condition. developmental and health benefits of breastfeeding should be considered along with the mother’s
Interactions
CYP3A4 inducers or inhibitors may affect estrogen drug metabolism
CYP3A4 inducers (eg, St. John's wort [Hypericum perforatum] preparations, phenobarbital, carbamazepine, and rifampin) may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile
CYP3A4 inhibitors (eg, erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir, grapefruit juice) may increase plasma concentrations of estrogens and may result in side effects

Mechanism of Action
Estradiol is a naturally occurring oestrogen. Oestrogens are responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. They modulate the pituitary secretion of gonadotrophins, LH and FSH through a negative feedback system.
