What Is Progesterone Used For?

INDICATIONS AND USAGE Progesterone capsules are indicated for use in the prevention of endometrial hyperplasia in nonhysterectomized postmenopausal women who are receiving conjugated estrogens tablets. They are also indicated for use in secondary amenorrhea.

Dosage and Administration

DOSAGE AND ADMINISTRATION Prevention of Endometrial Hyperplasia Progesterone capsules should be given as a single daily dose at bedtime, 200 mg orally for 12 days sequentially per 28-day cycle, to postmenopausal women with a uterus who are receiving daily conjugated estrogens tablets.

For these women, progesterone capsules should be taken with a glass of water while in the standing position.

Side Effects (Adverse Reactions)

ADVERSE REACTIONS See BOXED WARNING , WARNINGS and PRECAUTIONS. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials 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 multicenter, randomized, double-blind, placebo-controlled clinical trial, the effects of progesterone capsules on the endometrium was studied in a total of 875 postmenopausal women. Table 6 lists adverse experiences greater than or equal to 2 percent of women who received cyclic progesterone capsules, 200 mg daily (12 days per calendar month cycle) with 0.625 mg conjugated estrogens or placebo.

Table 7 lists adverse experiences greater than or equal to 5 percent of women who received progesterone or placebo. Table 7. Adverse Experiences (5%) Reported in Patients Using 400 mg/day in a Placebo-Controlled Trial in Estrogen-Primed Postmenopausal Women Adverse Experience Progesterone Capsules 400 mg Placebo n=25 n=24 Percentage (%) of Patients Fatigue 8 4 Headache 16 8 Dizziness 24 4 Abdominal Distention (Bloating) 8 8 Abdominal Pain (Cramping) 20 13 Diarrhea 8 4 Nausea 8 0 Back Pain 8 8 Musculoskeletal Pain 12 4 Irritability 8 4 Breast Pain 16 8 Infection Viral 12 0 Coughing 8 0 In a multicenter, parallel-group, open label postmarketing dosing study consisting of three consecutive 28-day treatment cycles, 220 premenopausal women with secondary amenorrhea were randomized to receive daily conjugated estrogens therapy (0.625 mg conjugated estrogens) and progesterone capsules, 300 mg per day (n=113) or Progesterone capsules, 400 mg per day (n=107) for 10 days of each treatment cycle. Overall, the most frequently reported treatment-emergent adverse reactions, reported in greater than or equal to 5 percent of subjects, were nausea, fatigue, vaginal mycosis, nasopharyngitis, upper respiratory tract infection, headache, dizziness, breast tenderness, abdominal distension, acne, dysmenorrhea, mood swing, and urinary tract infection. Postmarketing Experience: The following additional adverse reactions have been reported with progesterone capsules. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate the frequency or establish a causal relationship to drug exposure. Genitourinary System: endometrial carcinoma, hypospadia, intra-uterine death, menorrhagia, menstrual disorder, metrorrhagia, ovarian cyst, spontaneous abortion. Cardiovascular: circulatory collapse, congenital heart disease (including ventricular septal defect and patent ductus arteriosus), hypertension, hypotension, tachycardia. Gastrointestinal: acute pancreatitis, cholestasis, cholestatic hepatitis, dysphagia, hepatic failure, hepatic necrosis, hepatitis, increased liver function tests (including alanine aminotransferase increased, aspartate aminotransferase increased, gamma­glutamyl transferase increased), jaundice, swollen tongue. Skin: alopecia, pruritus, urticaria. Eyes:...

Active arterial thromboembolic disease (for example, stroke and myocardial infarction), or a history of these conditions. Known liver dysfunction or disease. Known or suspected pregnancy.

Pregnancy and Breastfeeding

E. Pregnancy Progesterone capsules should not be used during pregnancy. (See CONTRAINDICATIONS .) Pregnancy Category B: Reproductive studies have been performed in mice at doses up to 9 times the human oral dose, in rats at doses up to 44 times the human oral dose, in rabbits at a dose of 10 mcg/day delivered locally within the uterus by an implanted device, in guinea pigs at doses of approximately one-half the human oral dose and in rhesus monkeys at doses approximately the human dose, all based on body surface area, and have revealed little or no evidence of impaired fertility or harm to the fetus due to progesterone.

F. Nursing Women Detectable amounts of progestin have been identified in the milk of nursing women receiving progestins. Caution should be exercised when progesterone capsules are administered to a nursing woman.

Overdosage

OVERDOSAGE No studies on overdosage have been conducted in humans. In the case of overdosage, progesterone capsules should be discontinued and the patient should be treated symptomatically.
