Oral Micronized Progesterone Cost in Washington (2026)

What Oral Micronized Progesterone Costs in Washington Right Now

The price you pay depends on three variables: brand vs. generic vs. compounded, your insurance status, and which pharmacy you use. Brand-name Prometrium (manufactured originally by Solvay, now AbbVie) carries a manufacturer list price near $180 per month for the standard 100 mg or 200 mg capsule supply [1]. Most women in Washington do not pay that figure.

Generic oral micronized progesterone capsules average $45 per month across Washington retail pharmacies in 2026. That $45 figure reflects cash-pay pricing without insurance. Pharmacies in the Seattle metro area, Spokane, and Tacoma show similar cash prices within a $5 to $10 range, though independent pharmacies sometimes run lower. The FDA approved generic versions of Prometrium under ANDA filings that confirmed bioequivalence to the branded capsule, meaning the active ingredient (micronized progesterone in peanut oil) is pharmaceutically identical [1].

Compounded oral micronized progesterone from a licensed 503A pharmacy costs roughly $25 per month in Washington. This option requires a patient-specific prescription. The 2013 Drug Quality and Security Act (DQSA) governs 503A compounding nationally, and Washington's Pharmacy Quality Assurance Commission enforces state-level oversight of these pharmacies [2]. One consideration: compounded formulations skip the FDA approval process, so the Endocrine Society and the American College of Obstetricians and Gynecologists (ACOG) recommend FDA-approved products as first-line when available [3].

Generic vs. Brand vs. Compounded: A Price Breakdown

Generic micronized progesterone offers the best balance of cost, regulatory assurance, and availability for most Washington patients. Here is how the three options compare on price and oversight.

Brand Prometrium sits at roughly $180 per month before insurance. Few patients pay this out-of-pocket because most commercial formularies tier the generic at a lower copay. The brand product uses peanut oil as the suspension vehicle, which matters for patients with peanut allergies [1].

Generic versions, priced at that $45 per month average, use the same peanut oil suspension. They are AB-rated to Prometrium and dispensed at every major chain pharmacy in Washington, including Costco, Fred Meyer, Rite Aid, and Walmart. Costco and Walmart typically sit at the lower end of the cash-pay range.

Compounded progesterone at $25 per month can use alternative suspension vehicles (olive oil, for example), making it a practical choice for peanut-allergic patients. Dr. JoAnn V. Pinkerton, past president of the North American Menopause Society, has noted: "FDA-approved micronized progesterone should be preferred when possible, but compounded bioidentical progesterone from a reputable 503A pharmacy is a reasonable alternative when an allergy or intolerance prevents use of the approved product" [4]. Washington permits 503A compounding under state pharmacy law, provided the pharmacy holds a valid license from the Pharmacy Quality Assurance Commission.

Washington Medicaid Coverage for Oral Micronized Progesterone

Washington Apple Health (Medicaid) covers oral micronized progesterone, but it requires prior authorization (PA). The PA process confirms the prescriber's indication, typically endometrial protection during estrogen-based hormone replacement therapy in postmenopausal women or treatment of secondary amenorrhea.

The PA requirement adds a step but not usually a long delay. Washington's Health Care Authority (HCA) processes most pharmacy PAs within 24 hours through the state's point-of-sale system. Clinicians submit the PA electronically, documenting that the patient is on concurrent estrogen therapy or has another FDA-labeled indication [5].

Once approved, the Medicaid copay for generic oral micronized progesterone in Washington is typically $0 to $3 per fill. Brand Prometrium may require step therapy failure through the generic first. The PEPI trial (Postmenopausal Estrogen/Progestin Interventions, N=875) demonstrated that micronized progesterone combined with conjugated equine estrogens protected the endometrium from hyperplasia while producing a more favorable lipid profile than medroxyprogesterone acetate (MPA) [6]. That evidence base supports the medical necessity argument most PA submissions rely on.

Commercial Insurance Coverage Across Washington

Most commercial plans in Washington state include generic oral micronized progesterone on their formularies. Regence Blue Shield, Premera Blue Cross, Kaiser Permanente Washington, Molina Healthcare, and Coordinated Care all list generic micronized progesterone, typically on Tier 1 or Tier 2.

Copays range from $5 to $25 per month for generic, depending on the plan tier. Brand Prometrium, where covered, usually sits on Tier 3 with copays between $40 and $75. Some plans require generic substitution before covering brand.

The Affordable Care Act's preventive services mandate does not specifically classify progesterone for HRT as a zero-cost preventive service, so standard cost-sharing applies. Patients on high-deductible health plans (HDHPs) may pay the full $45 cash price until meeting their deductible. A useful tactic: ask your pharmacist to compare the insurance-billed price against the cash-pay price. In some HDHP scenarios, paying cash at $45 beats the negotiated rate applied toward a $3,000 deductible.

Washington's insurance commissioner has been clear about formulary transparency. The Office of the Insurance Commissioner (OIC) requires all carriers to publish their formularies online, so verifying coverage before filling a prescription takes only a few minutes on the insurer's drug lookup tool [7].

Telehealth Prescribing in Washington State

Washington permits telehealth prescribing of oral micronized progesterone statewide. No in-person visit is required for the initial prescription under current Washington telemedicine law, which was expanded during the COVID-19 public health emergency and made permanent through SB 5423 in 2021 [8].

This matters for cost. Telehealth visits typically cost $50 to $99 for a hormone consultation, compared with $150 to $300 for an in-office visit. HealthRX and other telehealth platforms licensed in Washington can prescribe oral micronized progesterone after a synchronous video or audio visit with a licensed prescriber.

Prescriptions written via telehealth are filled at the patient's pharmacy of choice, including mail-order pharmacies. Mail-order fills for 90-day supplies of generic oral micronized progesterone often reduce the per-month cost below the standard 30-day retail price. Some patients report 90-day generic fills at $100 to $110 through mail-order, effectively bringing the monthly cost to about $35.

How to Get the Lowest Price in Washington

Six strategies can reduce what you pay for oral micronized progesterone in Washington.

Use a generic. The $135 per month savings over brand Prometrium is the single largest cost lever. Generics are AB-rated and therapeutically equivalent [1].

Compare pharmacy prices. Cash-pay prices for generic oral micronized progesterone vary by $5 to $15 across Washington pharmacies. Costco does not require a membership for pharmacy purchases and often posts lower prices.

Ask about 90-day fills. Whether through mail-order or retail, 90-day supplies typically save 10% to 20% per capsule compared with monthly fills.

Use manufacturer or third-party discount cards. GoodRx, RxSaver, and similar platforms show real-time pricing at Washington pharmacies. These discount cards can bring generic micronized progesterone below $30 at select locations.

Consider 503A compounding. At $25 per month, compounded progesterone is the cheapest option. Confirm your pharmacy holds a current Washington 503A license. This route is best suited for patients with documented peanut allergy or those whose clinicians specifically recommend a compounded formulation.

File a Medicaid PA promptly. If you qualify for Washington Apple Health, the prior authorization process is straightforward and yields near-zero copays. Do not assume Medicaid will deny coverage.

Clinical Evidence Supporting Oral Micronized Progesterone

The evidence base for oral micronized progesterone in hormone therapy is well established, and it directly affects whether insurers and Medicaid programs cover the drug.

The PEPI trial (1995, N=875) was the first large randomized controlled trial to show that oral micronized progesterone, at 200 mg for 12 days per cycle, prevented endometrial hyperplasia as effectively as MPA when combined with conjugated equine estrogens. The micronized progesterone arm showed a 0% rate of endometrial hyperplasia over three years, compared with 0% for MPA and 34% for unopposed estrogen [6]. The trial also found that micronized progesterone preserved more of estrogen's beneficial effect on HDL cholesterol than MPA did.

The Endocrine Society's 2015 clinical practice guideline on postmenopausal hormone therapy states: "Micronized progesterone may be preferred over synthetic progestins because of a potentially better cardiovascular and breast safety profile" [3]. That language supports formulary inclusion and prior authorization approvals.

A French cohort study (E3N, N=80,377) published in Breast Cancer Research and Treatment followed postmenopausal women for a mean of 8.1 years. Women using estrogen combined with micronized progesterone showed no statistically significant increase in breast cancer risk (RR 1.00 to 95% CI 0.83 to 1.22), while those using synthetic progestins had a relative risk of 1.69 [9]. This finding, though observational, has influenced prescribing patterns in the United States and contributed to the growing preference for micronized progesterone over MPA.

The 2022 ACOG Practice Bulletin on hormone therapy reaffirmed that micronized progesterone is an appropriate progestogen for endometrial protection, citing both the PEPI data and the E3N cohort [10]. Washington Medicaid's formulary committee references these guidelines when evaluating PA requests.

Compounded Progesterone Legality and Safety in Washington

Compounded oral micronized progesterone is legal in Washington when dispensed by a pharmacy holding a valid 503A license from the state Pharmacy Quality Assurance Commission. The 503A designation, defined by Section 503A of the Federal Food, Drug, and Cosmetic Act as amended by the DQSA (2013), permits patient-specific compounding by a licensed pharmacist based on a valid prescription [2].

Washington has approximately 45 licensed 503A pharmacies that compound bioidentical hormones, concentrated in the Puget Sound region, Spokane, and the Tri-Cities. These pharmacies can compound oral micronized progesterone in capsule form, typically using a base other than peanut oil.

The FDA has repeatedly clarified that compounded drugs are not FDA-approved and do not undergo the same premarket review as commercial products [2]. The Endocrine Society's 2016 scientific statement on bioidentical hormones cautioned against assuming compounded products are safer or more effective than FDA-approved equivalents: "There is no scientific basis for claims that compounded bioidentical hormones are safer or more effective than FDA-approved hormones" [11].

For patients who choose compounding, the cost advantage is real ($25 vs. $45 per month). The trade-off is reduced regulatory oversight. Patients should verify that their compounding pharmacy participates in voluntary accreditation through the Pharmacy Compounding Accreditation Board (PCAB) or holds current state inspection records.

Dosing, Formulation, and What Your Prescription Looks Like

Standard dosing for oral micronized progesterone follows one of two schedules. Continuous dosing uses 100 mg nightly, taken every day of the month alongside continuous estrogen. Cyclic dosing uses 200 mg nightly for 12 to 14 days per calendar month, typically days 1 through 12 or days 15 through 26 [1].

The FDA-approved label specifies that the capsule should be taken at bedtime because progesterone's metabolite, allopregnanolone, causes drowsiness. This side effect doubles as a benefit for women experiencing menopause-related insomnia.

The capsules contain micronized progesterone suspended in peanut oil (brand and generic) or an alternative oil (compounded). "Micronized" means the progesterone particles have been reduced to a size that improves oral absorption. Without micronization, oral progesterone has poor bioavailability due to extensive first-pass hepatic metabolism [1].

Your Washington prescription will specify the drug name (progesterone, micronized), strength (100 mg or 200 mg), quantity (30 or 90 capsules), and directions (one capsule at bedtime, daily or cyclically). Pharmacists in Washington can substitute a generic for brand Prometrium unless the prescriber writes "DAW" (dispense as written) on the prescription.
