Full prescribing information FDA SPL
🎯 Indications and Usage ▾
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 a postmenopausal woman with a uterus who is receiving daily conjugated estrogens tablets. Treatment of Secondary Amenorrhea Progesterone capsules may be given as a single daily dose of 400 mg at bedtime for 10 days. Some women may experience difficulty swallowing progesterone capsules.
For these women, progesterone capsules should be taken with a glass of water while in the standing position.
⛔ Contraindications ▾
CONTRAINDICATIONS Progesterone capsules is contraindicated in women with any of the following conditions: Hypersensitivity to its ingredients. Progesterone capsules contain peanut oil and is contraindicated in patients allergic to peanuts. Abnormal genital bleeding of unknown etiology.
Known, suspected, or history of breast cancer. Active deep vein thrombosis, pulmonary embolism or history of these conditions. Active arterial thromboembolic disease (for example, stroke and myocardial infarction), or a history of these conditions.
Known liver dysfunction or disease.
⚠️ Warnings ▾
WARNINGS 1. Cardiovascular disorders Progesterone is contraindicated in females with active DVT, PE, arterial thromboembolic disease (e.g., stroke, MI) disease, or a history of these conditions (see CONTRAINDICATIONS). Immediately discontinue progesterone if a PE, DVT, stroke, or MI occurs or is suspected.
If feasible, discontinue progesterone at least 4 to 6 weeks before surgery of the type associated with an increased risk of thromboembolism, or during periods of prolonged immobilization. The safety and efficacy of estrogen plus progestogen for the prevention of cardiovascular disorders has not been established (see CLINICAL STUDIES). The Women’s Health Initiative (WHI) estrogen plus progestin trial reported increased risks of PE, DVT, stroke, and MI in postmenopausal women (50 to 79 years of age, average age 63.4 years) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo.
Analyses were also conducted in women aged 50 to 59 years, a group of women more likely to present with new onset of moderate to severe VMS compared to women in other age groups in the trial (see CLINICAL STUDIES). Only daily oral 0.625 mg CE and 2.5 mg MPA were studied in the estrogen plus progestin trial of the WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events to lower CE plus other MPA doses, other routes of administration, or other estrogen plus progestogen products is not known.
Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. a. Venous Thromboembolism In women aged 50 to 59 years, the WHI estrogen plus progestin trial reported a relative risk for PE of 2.05 (95% confidence interval [CI], 0.89, 4.71) for CE/MPA compared to placebo, with a risk difference of 6 per 10,000 women-years (WYs; 11 versus 5). The relative risk for DVT was 3.01 (95% CI, 1.36, 6.66) in those receiving CE/MPA compared to placebo, with a risk difference of 10 per 10,000 WYs (15 versus 5) (see CLINICAL STUDIES).
In the overall study population of women aged 50 to 79 years (average 63.4 years), the trial reported a relative risk for PE of 1.98 (95% CI, 1.36, 2.87) for CE/MPA compared to placebo, with a risk difference of 9 per 10,000 WYs (18 versus 9). The relative risk for DVT was 1.87 (95% CI, 1.37, 2.54) for CE/MPA compared to placebo, with a risk difference of 12 per 10,000 WYs (25 versus 14) (see CLINICAL STUDIES). b. Stroke In women aged 50 to 59 years, the WHI estrogen plus progestin trial reported a relative risk for stroke of 1.51 (95% CI, 0.81, 2.82) for CE/MPA compared to placebo, with a risk difference of 5 per 10,000 WYs (15 versus 10) (see CLINICAL STUDIES).
In the overall study population of women aged 50 to 79 years (average 63.4 years), the WHI estrogen plus progestin trial reported relative risk for stroke of 1.37 (95% CI, 1.07, 1.76) for CE/MPA compared to placebo, with a risk difference of 9 per 10,000 WYs (33 versus 24) (see CLINICAL STUDIES). c. Coronary Heart Disease In women 50 to 59 years of age, the WHI estrogen plus progestin trial reported a relative risk for coronary heart disease (CHD) events (defined as nonfatal MI, silent MI, or CHD death) of 1.34 (95% CI, 0.82, 2.19) for CE/MPA compared placebo, with a risk difference of 5 per 10,000 WYs (23 versus 17).
In the overall study population of women aged 50 to 79 years (average 63.4 years), the trial reported a relative risk of CHD of 1.18 (95% CI, 0.95, 1.45) for CE/MPA compared to placebo, with a risk difference of 6 per 10,000 WYs (41 versus 35) (see CLINICAL STUDIES). In the Heart and Estrogen/Progestin Replacement Study (HERS) and open label extension (HERS II), postmenopausal women with documented heart disease (n = 2,763, average age 66.7 years) received daily CE (0.625 mg) plus MPA or placebo. In Year 1, there were more CHD events in the CE plus MPA-treated group than… [Excerpted — this section continues on DailyMed.]
🤒 Adverse Reactions ▾
ADVERSE REACTIONS See 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 reactions 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.

🔄 Drug Interactions ▾
C. Drug–Laboratory Test Interactions The following laboratory results may be altered by the use of estrogen plus progestin therapy: Increased sulfobromophthalein retention and other hepatic function tests. Coagulation tests: increase in prothrombin factors VII, VIII, IX and X. Pregnanediol determination. Thyroid function: increase in PBI, and butanol extractable protein bound iodine and decrease in T3 uptake values.
🤰 Pregnancy ▾
E. Pregnancy Progesterone capsules should not be used during pregnancy. 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.
🧒 Pediatric Use ▾
G. Pediatric Use Progesterone capsules are not indicated in children. Clinical studies have not been conducted in the pediatric population.
🧓 Geriatric Use ▾
H. Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing progesterone capsules to determine whether those over 65 years of age differ from younger subjects in their response to progesterone capsules. The Women’s Health Initiative Study In the Women’s Health Initiative (WHI) estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age (see CLINICAL STUDIES and WARNINGS, Cardiovascular disorders and Malignant neoplasms ).
The Women’s Health Initiative Memory Study In the Women’s Health Initiative Memory Study (WHIMS) of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dementia in the estrogen plus progestin ancillary study when compared to placebo (see CLINICAL STUDIES ).
🆘 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.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Progesterone capsules are an oral dosage form of progesterone which is chemically identical to progesterone of ovarian origin. Pharmacokinetics A. Absorption After oral administration of progesterone as a soft-gelatin capsule formulation, maximum serum concentrations were attained within 3 hours.
The absolute bioavailability of progesterone is not known. Table 1 summarizes the mean pharmacokinetic parameters in postmenopausal women after five oral daily doses of progesterone capsules 100 mg as a soft-gelatin capsule formulation. TABLE 1.
Pharmacokinetic Parameters of Progesterone Capsules Parameter Progesterone Capsules Daily Dose 100 mg 200 mg 300 mg C max (ng/mL) 17.3 ± 21.9 a 38.1 ± 37.8 60.6 ±
72.5T max (hr) 1.5 ± 0.8 2.3 ± 1.4 1.7 ±
0.6AUC (0-10) (ng × hr/mL) 43.3 ± 30.8 101.2 ± 66 175.7 ± 170.3 a Mean ± S.D. Serum progesterone concentrations appeared linear and dose proportional following multiple dose administration of progesterone capsules 100 mg over the dose range 100 mg per day to 300 mg per day in postmenopausal women. Although doses greater than 300 mg per day were not studied in females, serum concentrations from a study in male volunteers appeared linear and dose proportional between 100 mg per day and 400 mg per day.
The pharmacokinetic parameters in male volunteers were generally consistent with those seen in postmenopausal women. B. Distribution Progesterone is approximately 96 percent to 99 percent bound to serum proteins, primarily to serum albumin (50 to 54 percent) and transcortin (43 to 48 percent).
C. Metabolism Progesterone is metabolized primarily by the liver largely to pregnanediols and pregnanolones. Pregnanediols and pregnanolones are conjugated in the liver to glucuronide and sulfate metabolites.
Progesterone metabolites which are excreted in the bile may be deconjugated and may be further metabolized in the intestine via reduction, dehydroxylation and epimerization. D. Excretion The glucuronide and sulfate conjugates of pregnanediol and pregnanolone are excreted in the bile and urine.
Progesterone metabolites are eliminated mainly by the kidneys. Progesterone metabolites which are excreted in the bile may undergo enterohepatic recycling or may be excreted in the feces. E.
Special Populations The pharmacokinetics of progesterone capsules have not been assessed in low body weight or obese patients. Hepatic Insufficiency: The effect of hepatic impairment on the pharmacokinetics of progesterone capsules has not been studied. Renal Insufficiency: The effect of renal impairment on the pharmacokinetics of progesterone capsules has not been studied.
F. Food–Drug Interaction Concomitant food ingestion increased the bioavailability of progesterone capsules relative to a fasting state when administered to postmenopausal women at a dose of 200 mg. G.
Drug Interactions The metabolism of progesterone by human liver microsomes was inhibited by ketoconazole (IC 50 <0.1 μM). Ketoconazole is a known inhibitor of cytochrome P450 3A4, hence these data suggest that ketoconazole or other known inhibitors of this enzyme may increase the bioavailability of progesterone. The clinical relevance of the in vitro findings is unknown.
Co-administration of conjugated estrogens and progesterone capsules to 29 postmenopausal women over a 12-day period resulted in an increase in total estrone concentrations (C max 3.68 ng/mL to 4.93 ng/mL) and total equilin concentrations (C max 2.27 ng/mL to 3.22 ng/mL) and a decrease in circulating 17β estradiol concentrations (C max 0.037 ng/mL to 0.030 ng/mL). The half-life of the conjugated estrogens was similar with co-administration of progesterone capsules. Table 2 summarizes the pharmacokinetic parameters.

⚠️ Precautions ▾
PRECAUTIONS A. General 1. Fluid Retention Progesterone may cause some degree of fluid retention.
Women with conditions that might be influenced by this factor, such as cardiac or renal dysfunction, warrant careful observation. 2. Dizziness and Drowsiness Progesterone capsules may cause transient dizziness and drowsiness and should be used with caution when driving a motor vehicle or operating machinery.
Progesterone capsules should be taken as a single daily dose at bedtime. B. Patient Information General: This product contains peanut oil and should not be used if you are allergic to peanuts.
Physicians are advised to discuss the contents of the Patient Information leaflet with patients for whom they prescribe Progesterone capsules. C. Drug–Laboratory Test Interactions The following laboratory results may be altered by the use of estrogen plus progestin therapy: Increased sulfobromophthalein retention and other hepatic function tests.
Coagulation tests: increase in prothrombin factors VII, VIII, IX and X. Pregnanediol determination. Thyroid function: increase in PBI, and butanol extractable protein bound iodine and decrease in T3 uptake values.
D. Carcinogenesis, Mutagenesis, Impairment of Fertility Progesterone has not been tested for carcinogenicity in animals by the oral route of administration. When implanted into female mice, progesterone produced mammary carcinomas, ovarian granulosa cell tumors and endometrial stromal sarcomas.
In dogs, long-term intramuscular injections produced nodular hyperplasia and benign and malignant mammary tumors. Subcutaneous or intramuscular injections of progesterone decreased the latency period and increased the incidence of mammary tumors in rats previously treated with a chemical carcinogen. Progesterone did not show evidence of genotoxicity in in vitro studies for point mutations or for chromosomal damage.
In vivo studies for chromosome damage have yielded positive results in mice at oral doses of 1000 mg/kg and 2000 mg/kg. Exogenously administered progesterone has been shown to inhibit ovulation in a number of species and it is expected that high doses given for an extended duration would impair fertility until the cessation of treatment. E.
Pregnancy Progesterone capsules should not be used during pregnancy. 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.
G. Pediatric Use Progesterone capsules are not indicated in children. Clinical studies have not been conducted in the pediatric population.
H. Geriatric Use There have not been sufficient numbers of geriatric women involved in clinical studies utilizing progesterone capsules to determine whether those over 65 years of age differ from younger subjects in their response to progesterone capsules. The Women’s Health Initiative Study In the Women’s Health Initiative (WHI) estrogen plus progestin substudy (daily CE [0.625 mg] plus MPA [2.5 mg] versus placebo), there was a higher relative risk of nonfatal stroke and invasive breast cancer in women greater than 65 years of age (see CLINICAL STUDIES and WARNINGS, Cardiovascular disorders and Malignant neoplasms ).
The Women’s Health Initiative Memory Study In the Women’s Health Initiative Memory Study (WHIMS) of postmenopausal women 65 to 79 years of age, there was an increased risk of developing probable dement… [Excerpted — this section continues on DailyMed.]

🧬 Pharmacokinetics ▾
Pharmacokinetics A. Absorption After oral administration of progesterone as a soft-gelatin capsule formulation, maximum serum concentrations were attained within 3 hours. The absolute bioavailability of progesterone is not known.
Table 1 summarizes the mean pharmacokinetic parameters in postmenopausal women after five oral daily doses of progesterone capsules 100 mg as a soft-gelatin capsule formulation. TABLE 1. Pharmacokinetic Parameters of Progesterone Capsules Parameter Progesterone Capsules Daily Dose 100 mg 200 mg 300 mg C max (ng/mL) 17.3 ± 21.9 a 38.1 ± 37.8 60.6 ±
72.5T max (hr) 1.5 ± 0.8 2.3 ± 1.4 1.7 ±
0.6AUC (0-10) (ng × hr/mL) 43.3 ± 30.8 101.2 ± 66 175.7 ± 170.3 a Mean ± S.D. Serum progesterone concentrations appeared linear and dose proportional following multiple dose administration of progesterone capsules 100 mg over the dose range 100 mg per day to 300 mg per day in postmenopausal women. Although doses greater than 300 mg per day were not studied in females, serum concentrations from a study in male volunteers appeared linear and dose proportional between 100 mg per day and 400 mg per day.
The pharmacokinetic parameters in male volunteers were generally consistent with those seen in postmenopausal women. B. Distribution Progesterone is approximately 96 percent to 99 percent bound to serum proteins, primarily to serum albumin (50 to 54 percent) and transcortin (43 to 48 percent).
C. Metabolism Progesterone is metabolized primarily by the liver largely to pregnanediols and pregnanolones. Pregnanediols and pregnanolones are conjugated in the liver to glucuronide and sulfate metabolites.
Progesterone metabolites which are excreted in the bile may be deconjugated and may be further metabolized in the intestine via reduction, dehydroxylation and epimerization. D. Excretion The glucuronide and sulfate conjugates of pregnanediol and pregnanolone are excreted in the bile and urine.
Progesterone metabolites are eliminated mainly by the kidneys. Progesterone metabolites which are excreted in the bile may undergo enterohepatic recycling or may be excreted in the feces. E.
Special Populations The pharmacokinetics of progesterone capsules have not been assessed in low body weight or obese patients. Hepatic Insufficiency: The effect of hepatic impairment on the pharmacokinetics of progesterone capsules has not been studied. Renal Insufficiency: The effect of renal impairment on the pharmacokinetics of progesterone capsules has not been studied.
F. Food–Drug Interaction Concomitant food ingestion increased the bioavailability of progesterone capsules relative to a fasting state when administered to postmenopausal women at a dose of 200 mg. G.
Drug Interactions The metabolism of progesterone by human liver microsomes was inhibited by ketoconazole (IC 50 <0.1 μM). Ketoconazole is a known inhibitor of cytochrome P450 3A4, hence these data suggest that ketoconazole or other known inhibitors of this enzyme may increase the bioavailability of progesterone. The clinical relevance of the in vitro findings is unknown.
Co-administration of conjugated estrogens and progesterone capsules to 29 postmenopausal women over a 12-day period resulted in an increase in total estrone concentrations (C max 3.68 ng/mL to 4.93 ng/mL) and total equilin concentrations (C max 2.27 ng/mL to 3.22 ng/mL) and a decrease in circulating 17β estradiol concentrations (C max 0.037 ng/mL to 0.030 ng/mL). The half-life of the conjugated estrogens was similar with co-administration of progesterone capsules. Table 2 summarizes the pharmacokinetic parameters.

🔬 Clinical Studies ▾
CLINICAL STUDIES Effects on the endometrium In a randomized, double-blind clinical trial, 358 postmenopausal women, each with an intact uterus, received treatment for up to 36 months. The treatment groups were: progesterone capsules at the dose of 200 mg per day for 12 days per 28-day cycle in combination with conjugated estrogens 0.625 mg per day (n=120); conjugated estrogens 0.625 mg per day only (n=119); or placebo (n=119). The subjects in all three treatment groups were primarily Caucasian women (87 percent or more of each group).
The results for the incidence of endometrial hyperplasia in women receiving up to 3 years of treatment are shown in Table 3. A comparison of the progesterone capsules plus conjugated estrogens treatment group to the conjugated estrogens only group showed a significantly lower rate of hyperplasia (6 percent combination product versus 64 percent estrogen alone) in the progesterone capsules plus conjugated estrogens treatment group throughout 36 months of treatment. TABLE 3.

This figure illustrates graphically that the proportion of patients with hyperplasia was significantly greater for the conjugated estrogens group (64 percent) compared to the conjugated estrogens plus progesterone capsules group (6 percent). Figure 1. Time to Hyperplasia in Women Receiving up to 36 Months of Treatment The discontinuation rates due to hyperplasia over the 36 months of treatment are as shown in Table 4.
For any degree of hyperplasia, the discontinuation rate for patients who received conjugated estrogens plus progesterone capsules was similar to that of the placebo only group, while the discontinuation rate for patients who received conjugated estrogens alone was significantly higher. Women who permanently discontinued treatment due to hyperplasia were similar in demographics to the overall study population. TABLE 4.

In a multicenter, parallel-group, open label, postmarketing dosing study that included premenopausal women with secondary amenorrhea for at least 90 days, administration of 10 days of progesterone capsules during two 28-day treatment cycles, 300 mg per day (n=107) or 400 mg per day (n=99), resulted in 73.8 percent and 76.8 percent of women, respectively, experiencing withdrawal bleeding. The rate of secretory transformation was evaluated in a… [Excerpted — this section continues on DailyMed.]
📄 Carcinogenesis, Mutagenesis, Impairment of Fertility ▾
D. Carcinogenesis, Mutagenesis, Impairment of Fertility Progesterone has not been tested for carcinogenicity in animals by the oral route of administration. When implanted into female mice, progesterone produced mammary carcinomas, ovarian granulosa cell tumors and endometrial stromal sarcomas.
In dogs, long-term intramuscular injections produced nodular hyperplasia and benign and malignant mammary tumors. Subcutaneous or intramuscular injections of progesterone decreased the latency period and increased the incidence of mammary tumors in rats previously treated with a chemical carcinogen. Progesterone did not show evidence of genotoxicity in in vitro studies for point mutations or for chromosomal damage.
In vivo studies for chromosome damage have yielded positive results in mice at oral doses of 1000 mg/kg and 2000 mg/kg. Exogenously administered progesterone has been shown to inhibit ovulation in a number of species and it is expected that high doses given for an extended duration would impair fertility until the cessation of treatment.

PATIENT INFORMATION Progesterone (proe-JESS-te-rone) Capsules (progesterone, USP), 100 mg and 200 mg Rx only Read this PATIENT INFORMATION before you start taking progesterone capsules and read what you get each time you refill your progesterone capsules prescription. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.
THIS PRODUCT CONTAINS PEANUT OIL AND SHOULD NOT BE USED IF YOU ARE ALLERGIC TO PEANUTS. What are progesterone capsules? Progesterone capsules contain the female hormone called progesterone.
What are progesterone capsules used for? Treatment of Menstrual Irregularities Progesterone capsules are used for the treatment of secondary amenorrhea (absence of menstrual periods in women who have previously had a menstrual period) due to a decrease in progesterone. When you do not produce enough progesterone, menstrual irregularities can occur.
If your healthcare provider has determined your body does not produce enough progesterone on its own, progesterone capsules may be prescribed to provide the progesterone you need. Protection of the Endometrium (Lining of the Uterus) Progesterone capsules are used in combination with estrogen-containing medications in a postmenopausal woman with a uterus (womb). Taking estrogen-alone increases the chance of developing a condition called endometrial hyperplasia that may lead to cancer of the lining of the uterus (womb).
The addition of a progestin is generally recommended for a woman with a uterus to reduce the chance of getting cancer of the uterus (womb). Who should not take progesterone capsules? Do not start taking progesterone capsules if you: Are allergic to peanuts Have unusual vaginal bleeding Currently have or have had certain cancers Estrogen plus progestin treatment may increase the chance of getting certain types of cancers, including cancer of the breast or uterus.
If you have or have had cancer, talk with your healthcare provider about whether you should take progesterone capsules. Had a stroke or heart attack Currently have or have had blood clots Currently have or have had liver problems Are allergic to progesterone capsules or any of its ingredients See the list of ingredients in progesterone capsules at the end of this leaflet. Tell your healthcare provider: If you are breastfeeding.
The hormone in progesterone capsules can pass into your breast milk. About all of your medical problems. Your healthcare provider may need to check you more carefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis, lupus, problems with your heart, liver, thyroid, or kidneys, or have high calcium levels in your blood.
About all the medicines you take. This includes prescription and nonprescription medicines, vitamins and herbal supplements. Some medicines may affect how progesterone capsules work.
Progesterone capsules may also affect how your other medicines work. How should I take progesterone capsules? 1.
Prevention of Endometrial Hyperplasia: A post-menopausal woman with a uterus who is taking estrogens should take a single daily dose of 200 mg progesterone capsules at bedtime for 12 continuous days per 28-day cycle. 2. Secondary Amenorrhea: progesterone capsules may be given as a single daily dose of 400 mg at bedtime for 10 days.
3. Progesterone capsules are to be taken at bedtime as some women become very drowsy and/or dizzy after taking progesterone capsules. In a few cases, symptoms may include blurred vision, difficulty speaking, difficulty with walking and feeling abnormal.
If you experience these symptoms, discuss them with your healthcare provider right away. 4. If you experience difficulty in swallowing progesterone capsules, it is recommended that you take your daily dose at bedtime with a glass of water while in the standing position.
