Full Prescribing Information
Indications & Usage
1 INDICATIONS AND USAGE PREMPRO/PREMPHASE is an estrogen plus progestin indicated in a woman with a uterus for: • Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause ( 1.1 ) • Treatment of Moderate to Severe Vulvar and Vaginal Atrophy due to Menopause ( 1.2 ) • Prevention of Postmenopausal Osteoporosis ( 1.3 ) 1.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause 1.2 Treatment of Moderate to Severe Vulvar and Vaginal Atrophy due to Menopause 1.3 Prevention of Postmenopausal Osteoporosis
Dosage & Administration
2 DOSAGE AND ADMINISTRATION 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. PREMPRO: one tablet containing conjugated estrogens (CE) plus medroxyprogesterone acetate (MPA) taken orally once daily. ( 2 ) PREMPHASE: one maroon tablet containing 0.625 mg CE taken orally on days 1 through 14, and one light-blue tablet containing 0.625 mg CE plus 5.0 mg MPA taken orally on days 15 through 28. ( 2 ) 2.1 Treatment of Moderate to Severe Vasomotor Symptoms due to Menopause PREMPRO therapy consists of a single tablet to be taken orally once daily. PREMPHASE therapy consists of two separate tablets: one maroon 0.625 mg Premarin [conjugated estrogens (CE)] tablet taken daily on days 1 through 14 and one light-blue tablet containing 0.625 mg CE and 5 mg of medroxyprogesterone acetate (MPA) taken on days 15 through 28. 2.2 Treatment of Moderate to Severe Vulvar and Vaginal Atrophy due to Menopause PREMPRO therapy consists…
Contraindications
4 CONTRAINDICATIONS PREMPRO and PREMPHASE are contraindicated in women with any of the following conditions: • Undiagnosed abnormal genital bleeding [see Warnings and Precautions (5.2) ] • Breast cancer or a history of breast cancer [see Warnings and Precautions (5.2) ] • Estrogen-dependent neoplasia [see Warnings and Precautions (5.2) ] • Active DVT, PE, or a history of these conditions [see Warnings and Precautions (5.1) ] • Active arterial thromboembolic disease (for example, stroke and MI), or a history of these conditions [see Warnings and Precautions (5.1) ] • Known anaphylactic reaction or angioedema with PREMPRO/PREMPHASE [see Warnings and Precautions (5.15 , 5.16 )] • Hepatic impairment or disease [see Warnings and Precautions (5.10) ] • Protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders • Undiagnosed abnormal genital bleeding ( 4 ) • Breast cancer or history of breast cancer ( 4 , 5.2 ) • Estrogen-dependent neoplasia ( 4 , 5.2 ) • Active DVT, PE, or a history of these conditions ( 4 , 5.1 ) • Active arterial thromboembolic disease (for example, stroke and MI), or a history of these conditions ( 4 , 5.1 ) • Known anaphylactic reaction …
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 plus MPA. • Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism ( 7.1 ) • Aminoglutethimide administered concomitantly with MPA may significantly depress the bioavailability of medroxyprogesterone acetate ( 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 s…
Adverse Reactions
6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Cardiovascular Disorders [see Boxed Warning , Warnings and Precautions (5.1) ] • Malignant Neoplasms [see Boxed Warning , Warnings and Precautions (5.2) ] In two prospective, randomized clinical studies, the most common adverse reactions >5% are abdominal pain, asthenia, back pain, headache, flatulence, nausea, depression, pruritus, breast pain, dysmenorrhea, and leukorrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trial of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In a 1-year clinical trial that included 678 postmenopausal women treated with PREMPRO and 351 postmenopausal women treated with PREMPHASE, the following adverse reactions occurred at a rate ≥ 1%, see Table 1 .
