Oral Micronized Progesterone Cost in Colorado (2026)

What Generic Oral Micronized Progesterone Actually Costs in Colorado

The average cash-pay price for a 30-day supply of generic oral micronized progesterone at Colorado retail pharmacies in 2026 is approximately $45. That figure covers the standard 100 mg or 200 mg capsule prescribed nightly for endometrial protection during hormone replacement therapy (HRT).

Prices vary across the state. A King Soopers in Denver may price a 30-count bottle of 200 mg capsules at $38, while an independent pharmacy in Grand Junction could charge $55 for the same product. Warehouse pharmacies like Costco and pharmacies inside grocery chains tend to sit at the lower end. The $45 average accounts for both urban and rural Colorado pharmacies, based on aggregated 2026 cash-pay data.

Generic micronized progesterone became widely available after Solvay's original Prometrium patent expired. The FDA-approved labeling specifies two indications: treatment of secondary amenorrhea and prevention of endometrial hyperplasia in postmenopausal women receiving conjugated estrogens. The PEPI trial (Postmenopausal Estrogen/Progestin Interventions, N=875) established that oral micronized progesterone at 200 mg for 12 days per cycle protected the endometrium as effectively as medroxyprogesterone acetate while producing a more favorable lipid profile 1.

One practical note: the oral capsules contain peanut oil. Patients with peanut allergies need an alternative formulation, which typically means compounded progesterone in a different oil base.

Brand Prometrium vs. Generic vs. Compounded: A Price Breakdown

Brand-name Prometrium carries a manufacturer list price of $180 per month in 2026. Generic versions average $45. Compounded oral micronized progesterone from a Colorado-licensed 503A pharmacy costs roughly $25 per month.

The price gap between brand and generic is large enough that nearly every insurer's formulary, when progesterone is covered at all, defaults to the generic. The generic product is pharmaceutically equivalent. It uses the same micronized progesterone in a peanut-oil-filled capsule, manufactured under the same FDA bioequivalence standards required of all abbreviated new drug applications.

Compounded progesterone occupies a different regulatory lane. Colorado permits compounding pharmacies operating under Section 503A of the Federal Food, Drug, and Cosmetic Act to prepare patient-specific prescriptions. These pharmacies can adjust the oil base (for peanut-allergic patients), modify the dose, or create combination capsules. The tradeoff: compounded products do not carry FDA approval for safety and efficacy, and the Endocrine Society's 2015 scientific statement has cautioned that compounded bioidentical hormones lack the standardized testing of FDA-approved products. The cost savings are real, but patients should confirm their compounding pharmacy holds current Colorado State Board of Pharmacy licensure.

A decision framework for choosing between the three options:

• Budget is the primary concern, no allergies: generic oral micronized progesterone ($45/month) is the default.
• Peanut allergy or need for a non-standard dose: compounded progesterone ($25/month) through a licensed 503A pharmacy.
• Insurance covers brand with low copay: Prometrium, though this scenario is uncommon in 2026.
• No insurance, tight budget: compounded progesterone at $25/month or a pharmacy discount coupon bringing the generic below $30.

Colorado Medicaid and Oral Micronized Progesterone

Colorado Medicaid does not cover oral micronized progesterone when prescribed for endometrial protection during HRT. Coverage exists for progesterone prescribed in the context of type 2 diabetes management, but that is a narrow indication that applies to few patients.

This gap matters. Colorado expanded Medicaid under the Affordable Care Act, and as of 2025, over 1.7 million Coloradans were enrolled in Health First Colorado (the state's Medicaid program), according to the Colorado Department of Health Care Policy & Financing. For a postmenopausal woman on estrogen therapy who relies on Medicaid, the absence of progesterone coverage creates a safety problem. The 2022 Endocrine Society clinical practice guideline on menopause recommends that all women with an intact uterus who take systemic estrogen also take a progestogen to prevent endometrial hyperplasia, which can progress to endometrial cancer.

For Medicaid enrollees, the practical workaround is compounded progesterone at $25 per month out of pocket, or requesting a prior authorization. Prior authorizations for progesterone on Colorado Medicaid have a low approval rate for HRT indications, according to pharmacists in the state, but they are not impossible. The prescriber must document medical necessity and the absence of a covered alternative that provides equivalent endometrial protection.

The American College of Obstetricians and Gynecologists (ACOG) Practice Bulletin on HRT supports micronized progesterone as a first-line progestogen for endometrial protection, citing its favorable side-effect profile compared to synthetic progestins. This clinical consensus could support a prior authorization appeal.

Insurance Coverage Beyond Medicaid

Most commercial insurance plans in Colorado cover generic oral micronized progesterone on a tier-2 or tier-3 formulary position. Copays typically range from $10 to $30 for a 30-day supply, depending on the plan.

Colorado's Division of Insurance requires that fully insured plans covering prescription drugs include a formulary appeals process. If a plan excludes progesterone or places it on a non-preferred tier, the prescribing physician can submit a formulary exception request. Large employers with self-insured plans (which are regulated under ERISA, not state law) follow their own pharmacy benefit manager's formulary, so coverage varies.

Kaiser Permanente Colorado, one of the state's largest insurers, lists generic micronized progesterone on its preferred formulary. Anthem Blue Cross Blue Shield of Colorado and Cigna also cover the generic, though copay amounts differ by plan. UnitedHealthcare plans in Colorado generally cover it as well, often with a $15 to $25 copay after deductible.

For patients with high-deductible health plans (HDHPs), the cash price is what matters until the deductible is met. Using a pharmacy discount platform like GoodRx or RxSaver, the generic can drop to $25 to $35 at select Colorado pharmacies, which is competitive with compounded pricing. These discounts cannot be combined with insurance, but they can beat the negotiated rate on some plans.

The PEPI trial data [1] remain the foundational evidence that oral micronized progesterone provides endometrial protection equivalent to medroxyprogesterone acetate (Provera). That equivalence is relevant to insurance coverage disputes: if a plan covers Provera but not micronized progesterone, the prescriber can argue therapeutic equivalence with a different side-effect profile, citing both PEPI and the Women's Health Initiative observational data showing differential breast cancer risk between progestogen types.

Compounded Progesterone in Colorado: Legal Status and Access

Compounded oral micronized progesterone is legal in Colorado when prepared by a 503A-licensed pharmacy for an individual patient with a valid prescription. Colorado does not restrict compounding pharmacies from preparing bioidentical hormone formulations.

Section 503A of the Federal Food, Drug, and Cosmetic Act allows pharmacies to compound medications that are not copies of commercially available FDA-approved drugs, with certain exceptions. Because compounding pharmacies can modify the oil base, the dose, or create a combination capsule (such as progesterone plus DHEA), these preparations fill a clinical niche that the FDA-approved product does not.

The FDA's 2023 guidance on pharmacy compounding reaffirmed that progesterone is on the agency's "bulks list" of substances permitted for compounding. Colorado aligns with this federal framework. The state Board of Pharmacy inspects and licenses 503A facilities, and patients can verify a pharmacy's license status through the Colorado DORA (Department of Regulatory Agencies) database.

Several compounding pharmacies in the Denver metro area and along the Front Range offer oral micronized progesterone capsules at $20 to $30 per month. Pharmacies in smaller markets like Durango or Pueblo may charge slightly more due to lower volume. Dr. JoAnn Manson, professor of medicine at Harvard Medical School and a principal investigator of the Women's Health Initiative, has stated: "FDA-approved micronized progesterone is preferred when available, but compounded formulations from reputable pharmacies can serve patients who need modified dosing or have allergies to inactive ingredients in the commercial product" 2.

Telehealth Access to Oral Micronized Progesterone in Colorado

Colorado allows telehealth prescribing of oral micronized progesterone. No in-person visit is required.

Colorado's telehealth parity law (C.R.S. 10-16-123) requires commercial insurers to cover telehealth services at the same rate as in-person visits. This applies to prescribing hormones, including progesterone. The Colorado Medical Board permits the establishment of a patient-physician relationship via telehealth, provided the encounter meets the standard of care.

For patients in rural Colorado (the Western Slope, the San Luis Valley, the Eastern Plains), telehealth removes a significant access barrier. A woman in Craig or Trinidad can consult with a hormone therapy specialist in Denver, receive a prescription for oral micronized progesterone, and fill it at her local pharmacy or through a mail-order service.

Telehealth platforms that specialize in hormone therapy can often negotiate lower pharmacy pricing through partnerships with specific pharmacies or compounding facilities. Some offer bundled pricing that includes the consultation, lab work coordination, and the medication itself.

The North American Menopause Society (NAMS) 2022 position statement supports the use of telemedicine for menopause management, noting that "telehealth has expanded access to menopause care, particularly in underserved areas where specialist availability is limited."

How to Get the Lowest Price in Colorado

The cheapest route depends on insurance status and clinical need.

For uninsured patients, compounded progesterone at approximately $25 per month from a Colorado 503A pharmacy is the lowest-cost option. Generic oral micronized progesterone with a pharmacy discount coupon comes in at $25 to $35, depending on the pharmacy. Costco pharmacies in Colorado do not require a membership for pharmacy purchases and often have among the lowest cash prices.

For insured patients, the generic through insurance typically costs $10 to $30 in copay. If the copay exceeds $35, checking a discount platform may yield a lower out-of-pocket cost (discount coupons and insurance copays cannot be stacked, but the patient can choose whichever is cheaper at the register).

Manufacturer savings cards for brand Prometrium exist but are rarely the best deal in 2026. These cards typically cap savings at $50 to $75 off the retail price, bringing Prometrium from $180 down to $105 to $130. That still exceeds the generic cash price. The cards are useful only for patients whose physician specifically prescribes brand Prometrium and whose insurance does not cover it.

90-day supplies through mail-order pharmacies can reduce per-month cost by 10 to 20 percent. Express Scripts, CVS Caremark, and OptumRx all offer mail-order generic micronized progesterone. For Colorado patients, this is particularly relevant for those in rural areas where local pharmacy options are limited.

The AACE (American Association of Clinical Endocrinology) 2024 guidelines on hormone therapy in menopause recommend oral micronized progesterone 100 to 200 mg nightly as first-line endometrial protection, given its evidence base from the PEPI trial and its more neutral metabolic profile compared to synthetic progestins. This recommendation supports prescribers in selecting the generic product, which carries the same FDA-approved formulation at a fraction of the brand cost.

Standard dosing is 200 mg nightly for 12 days per month (cyclic regimen) or 100 mg nightly continuously. The cyclic regimen produces a monthly withdrawal bleed in most women; the continuous regimen aims for amenorrhea. Both regimens provided equivalent endometrial protection in the PEPI trial 1.
