Dosage & Administration
2 DOSAGE AND ADMINISTRATION Generally, when estrogen therapy is prescribed for a postmenopausal woman with a uterus, a progestin should be considered to reduce the risk of endometrial cancer [see Boxed Warning ]. A woman without a uterus does not need progestin. In some cases, however, hysterectomized women with a history of endometriosis may need a progestin [see Warnings and Precautions (5.2, 5.16) ] . 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. Postmenopausal women should be re-evaluated periodically as clinically appropriate to determine if treatment is still necessary. Conjugated Estrogens Tablets may be taken without regard to meals. • Daily administration of 0.3, 0.45, 0.625, 0.9, and 1.25 mg ( 2.1 , 2.2 , 2.3 , 2.5 , 2.6 ) • Cyclic administration of 0.3, 0.625, and 1.25 mg ( 2.1 , 2.2 , 2.3 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause Patients should be treated with the lowest effective dose. Generally, women should be started at 0.3 mg Conjugated Estrogens Tablets daily. Subsequent dosage adju…

Drug Interactions
7 DRUG INTERACTIONS Data from a single-dose drug-drug interaction study involving CE and MPA indicate that the pharmacokinetic disposition of both drugs is not altered when the drugs are coadministered. No other clinical drug-drug interaction studies have been conducted with CE. Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism ( 7.1 ) 7.1 Metabolic Interactions In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4, such as 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. Inhibitors of CYP3A4, such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice, may increase plasma concentrations of estrogens and may result in side effects.
Adverse Reactions
6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in labeling: • Cardiovascular Disorders [see Boxed Warning , Warnings and Precautions (5.1) ] • Malignant Neoplasms [see Boxed Warning , Warnings and Precautions (5.2) ] Most common adverse reactions (≥5%) are: abdominal pain, asthenia, pain, back pain, headache, flatulence, nausea, depression, insomnia, breast pain, endometrial hyperplasia, leucorrhea, vaginal hemorrhage, and vaginitis.

During the first year of a 2-year clinical trial with 2,333 postmenopausal women with a uterus between 40 and 65 years of age (88% Caucasian), 1,012 women were treated with CE, and 332 were treated with placebo.
