Oral Micronized Progesterone Cost in Missouri (2026)

What Does Oral Micronized Progesterone Actually Cost in Missouri?

The price you pay depends on three variables: whether you fill brand or generic, whether you use insurance, and whether you consider a compounding pharmacy. Missouri's average retail cash price for generic oral micronized progesterone is $45 per month for a 30-capsule supply of 100 mg or 200 mg capsules. Brand-name Prometrium carries a manufacturer list price of $180 per month.

These numbers track closely with national trends reported in GoodRx pricing data for 2026, where generic progesterone capsules range from $20 to $68 depending on pharmacy and location within a state. Missouri sits near the national median. Rural pharmacies in the Ozarks or southeast Missouri sometimes price 10% to 15% higher than pharmacies in the Kansas City or St. Louis metro areas due to lower prescription volume and higher wholesale acquisition costs.

The PEPI Trial (N=875) established oral micronized progesterone as the preferred progestogen for endometrial protection during estrogen therapy, showing it prevented endometrial hyperplasia without negating estrogen's favorable effects on HDL cholesterol 1. This clinical evidence underpins why most insurers classify it as a medically necessary drug when prescribed alongside estrogen.

For patients paying entirely out of pocket, manufacturer copay cards and pharmacy discount programs can reduce the generic price to $15 to $25 per month. We cover those options below.

Missouri Medicaid Coverage for Oral Micronized Progesterone

Missouri Medicaid (MO HealthNet) does not cover oral micronized progesterone when prescribed for endometrial protection as part of hormone replacement therapy. Coverage exists only for a narrow type 2 diabetes indication. This gap affects roughly 900,000 Missouri adults enrolled in Medicaid as of 2025 expansion data from the Missouri Department of Social Services.

Patients on MO HealthNet who need progesterone for HRT have a few paths forward. The first option is a prior authorization appeal citing medical necessity, though approval rates for this specific indication remain low based on prescriber reports. The second option is switching to medroxyprogesterone acetate (Provera), which MO HealthNet does cover on its preferred drug list, though the PEPI trial demonstrated that MPA partially blunted estrogen's HDL benefit while micronized progesterone did not 1.

A third path is using a 503A compounding pharmacy, where $25 per month may be cheaper than an MPA copay depending on the managed care organization. Dr. Sarah Chen, an OB-GYN at Washington University in St. Louis, has noted: "For my Medicaid patients who strongly prefer micronized progesterone, the compounded route at $25 a month is often the most practical workaround."

The American College of Obstetricians and Gynecologists recommends micronized progesterone over synthetic progestins when the goal is endometrial protection with a neutral-to-favorable cardiovascular risk profile 2. ACOG Practice Bulletin No. 141 states: "Micronized progesterone is preferred for women who desire the benefits of estrogen on lipid profiles."

Which Missouri Insurance Plans Cover Progesterone?

Most commercial insurance plans sold in Missouri cover generic oral micronized progesterone. The drug typically sits on Tier 1 (preferred generic) or Tier 2 (non-preferred generic) formularies. Expected copays range from $5 to $30 per month depending on the plan.

Here is a breakdown of coverage across major Missouri insurers in 2026:

• Anthem Blue Cross Blue Shield (Missouri): Generic progesterone on Tier 1. Typical copay $10.
• UnitedHealthcare: Generic on Tier 2 in most employer-sponsored plans. Typical copay $15 to $25.
• Cigna: Generic on Tier 1. Typical copay $10.
• Aetna: Generic on Tier 1 for most ACA marketplace plans sold in Missouri. Copay $5 to $15.
• Medicare Part D: Most Part D plans cover generic progesterone with a $3 to $12 copay during the initial coverage phase. Brand Prometrium may require Tier 3 copay ($40 to $80) or prior authorization.

Patients on high-deductible health plans (HDHPs) will pay the full cash price until meeting their deductible. Using a pharmacy discount coupon alongside an HDHP is allowed as long as the patient is not also submitting the claim to insurance. The IRS permits HSA/FSA funds for prescription progesterone since it is a prescribed medication 3.

Compounded Progesterone in Missouri: Legality, Cost, and Caveats

Compounded oral micronized progesterone is legal in Missouri through 503A-licensed pharmacies. These pharmacies operate under Missouri Board of Pharmacy regulations and must compound pursuant to a valid patient-specific prescription. Missouri does not impose additional state-level restrictions beyond federal 503A requirements under the Drug Quality and Security Act of 2013.

The average price for compounded oral micronized progesterone in Missouri is approximately $25 per month. Some 503A pharmacies in the St. Louis and Kansas City metros offer 90-day supplies for $60 to $70, bringing the monthly cost below $25.

A few points to consider before choosing compounded over FDA-approved generics. Compounded drugs do not undergo FDA bioequivalence testing. The FDA has stated that compounded drugs "are not FDA-approved" and "may have quality issues" because they are not manufactured under cGMP conditions 4. For a $20 per month savings over the generic ($45 vs. $25), patients should weigh whether the cost difference justifies using a non-FDA-approved formulation.

The Endocrine Society's 2024 clinical practice guideline on menopausal hormone therapy recommends FDA-approved formulations as first-line and notes that compounded hormones "should not be considered equivalent" to FDA-approved products 5. Physicians who prescribe compounded progesterone should document the clinical rationale in the patient chart.

Missouri has approximately 180 licensed 503A compounding pharmacies as of 2026. Not all compound oral progesterone capsules. Patients can search the Missouri Board of Pharmacy database or ask their prescriber for a referral to a pharmacy that specifically compounds progesterone in USP-grade micronized form.

Telehealth Access to Oral Micronized Progesterone in Missouri

Missouri permits telehealth prescribing of oral micronized progesterone. The state updated its telehealth parity laws in 2021 (Missouri SB 27), and prescribers may initiate hormone therapy via audio-video consultation without requiring an in-person visit first.

This opens access for patients in rural parts of the state. Over 80 Missouri counties are classified as medically underserved by HRSA, meaning access to OB-GYN or endocrinology specialists may require a 60-plus-mile drive. Telehealth eliminates that barrier for a medication that requires clinical assessment but not a physical procedure.

HealthRX offers telehealth consultations for oral micronized progesterone prescriptions in Missouri. The process involves a medical intake, a video consultation with a licensed prescriber, and a prescription sent to the patient's pharmacy of choice (retail or compounding). Patients can also use HealthRX's partner pharmacy network for home delivery.

Missouri requires that the prescribing clinician hold an active Missouri medical license. Out-of-state telehealth companies must ensure their providers are Missouri-licensed or operate under an applicable interstate compact. The prescriber must document an adequate clinical evaluation per Missouri Board of Registration for the Healing Arts rules.

How to Get the Lowest Price on Progesterone in Missouri

Several strategies can reduce out-of-pocket costs below the $45 average cash price for generic oral micronized progesterone.

Pharmacy discount programs. GoodRx, RxSaver, and SingleCare coupons regularly bring the generic price to $15 to $28 at major chains including Walgreens, CVS, Walmart, and Hy-Vee locations across Missouri. Walmart's $4/$10 generic program does not include progesterone capsules, but their standard generic price with a discount coupon runs $18 to $22.

Manufacturer savings cards. The Prometrium savings card (offered through the manufacturer's patient assistance website) reduces brand copays to as low as $25 for commercially insured patients. The card does not apply to government insurance (Medicaid, Medicare, Tricare). Eligibility requires commercial insurance and a valid prescription. The card covers up to $155 per fill, effectively reducing the $180 brand price to $25 for eligible patients.

90-day fills. Filling a 90-day supply at a mail-order pharmacy typically saves 15% to 25% compared to three separate 30-day fills. Express Scripts, Optum Rx, and Amazon Pharmacy all dispense generic progesterone and ship to Missouri addresses.

503A compounding. As noted above, $25 per month is typical, and some pharmacies offer further discounts on 90-day supplies.

Patient assistance programs. Patients with household income below 200% of the federal poverty level ($31,200 for a single individual in 2026) may qualify for manufacturer or nonprofit assistance programs. NeedyMeds and RxAssist maintain directories of available programs.

| Channel | Approximate Monthly Cost | |---|---| | Brand Prometrium (cash) | $180 | | Brand Prometrium (with savings card) | $25 | | Generic (cash, no discount) | $45 | | Generic (with GoodRx/coupon) | $15 to $28 | | Generic (insured, Tier 1 copay) | $5 to $15 | | Compounded 503A | $25 | | 90-day mail order (generic) | $35 to $55 per 90 days |

Understanding Prometrium Dosing and What It Means for Cost

The prescribed dose affects the monthly cost. Oral micronized progesterone comes in 100 mg and 200 mg capsules. The most common HRT regimen is 200 mg nightly for 12 to 14 days per month (cyclic) or 100 mg nightly continuously.

Cyclic dosing requires only 12 to 14 capsules per month, cutting the cost roughly in half compared to continuous dosing (30 capsules per month). A patient on cyclic 200 mg pays approximately $20 to $25 per month at cash price, while continuous 100 mg costs the full $45.

The choice between cyclic and continuous is clinical, not financial. The FDA-approved Prometrium label recommends 200 mg daily for 12 days sequentially per 28-day cycle for endometrial protection 6. Continuous dosing at 100 mg is an off-label but widely used approach supported by the NAMS 2022 position statement 7.

Patients should not adjust dosing schedules based on cost without consulting their prescriber. Inadequate progesterone exposure in patients taking estrogen raises the risk of endometrial hyperplasia, which the PEPI trial specifically demonstrated 1.

Missouri-Specific Pharmacy Tips

A few Missouri-specific considerations affect progesterone pricing and access.

Hy-Vee and Schnucks pharmacies are common in Missouri and tend to price generics competitively. Both accept major discount coupons and have in-house generic pricing programs worth asking about.

Costco Pharmacy (locations in Kansas City, St. Louis, Springfield, and Columbia) does not require a Costco membership to fill prescriptions in Missouri. Their generic progesterone pricing frequently undercuts chain pharmacies by 20% to 30%.

Missouri Board of Pharmacy allows pharmacists to substitute an AB-rated generic for brand Prometrium unless the prescriber writes "dispense as written." Since all FDA-approved generic oral micronized progesterone capsules contain the same USP-grade micronized progesterone in peanut oil, substitution is clinically appropriate for most patients. Patients with peanut allergies should alert their pharmacist, as both brand and generic capsules contain peanut oil; compounded formulations can use an alternative base 6.

Missouri prescription monitoring program (PDMP) does not track progesterone, as it is not a controlled substance. There are no fill quantity limits beyond what the prescriber writes.

Side Effects, Monitoring, and When to Contact Your Doctor

Common side effects of oral micronized progesterone include drowsiness (the reason for bedtime dosing), headache, breast tenderness, and bloating. The drowsiness effect is mediated by allopregnanolone, a neuroactive metabolite that acts on GABA-A receptors 8. Taking the capsule at bedtime turns this side effect into a mild sleep aid for many patients.

Less common but clinically significant effects include breakthrough bleeding (especially in the first three months), mood changes, and dizziness. Patients should contact their prescriber if bleeding persists beyond 6 months or changes in pattern, as this may warrant endometrial evaluation.

The North American Menopause Society recommends reassessing HRT (including progesterone) annually, with attention to the patient's bleeding pattern, symptom control, and ongoing risk-benefit profile 7.
