Prometrium Cost in Washington (2026): Prices, Insurance, and Savings

What Prometrium Actually Costs in Washington

The sticker price rarely reflects what patients pay. AbbVie lists brand-name Prometrium at roughly $180 per month, but that number applies almost exclusively to uninsured patients filling at full retail without any discount tools. Across Washington pharmacies in 2026, the average cash-pay price for generic micronized progesterone 100 mg capsules (30-count) sits near $45 per month, based on aggregated pharmacy pricing data.

Prices vary by pharmacy. A Costco in Seattle may charge $15 to $20 less than an independent pharmacy in Spokane for the identical generic. Patients filling 200 mg capsules for cyclical use (typically 12 days per cycle) often pay less per fill because they need fewer capsules monthly. The FDA-approved labeling for Prometrium specifies 200 mg daily for 12 days sequentially per 28-day cycle for endometrial protection, which amounts to 12 capsules rather than 30 [1]. Generic micronized progesterone has been available since 2004, and the FDA Orange Book lists multiple AB-rated generic manufacturers, keeping competitive pressure on pricing [2].

For context, the PEPI trial (N=875) established micronized progesterone as the preferred progestogen for endometrial protection during estrogen therapy, demonstrating effective prevention of endometrial hyperplasia without the adverse lipid effects seen with medroxyprogesterone acetate [3]. That evidence base is why Prometrium remains widely prescribed and broadly covered.

Washington Medicaid Coverage for Prometrium

Washington Apple Health (the state Medicaid program) covers Prometrium, but requires prior authorization. The prescribing clinician must document a medically accepted indication, typically either secondary amenorrhea or endometrial hyperplasia prevention in patients receiving conjugated estrogens. The Washington Health Care Authority preferred drug list specifies generic micronized progesterone as preferred, with brand-name Prometrium requiring step therapy documentation showing the generic was tried or is clinically inappropriate.

Processing PA requests through Apple Health usually takes 24 to 72 hours. Pharmacists can dispense a 72-hour emergency supply under Washington state pharmacy rules while PA is pending. The Endocrine Society clinical practice guidelines recommend micronized progesterone as a first-line progestogen for menopausal hormone therapy, which supports PA approval for this use [4].

Patients enrolled in Washington Medicaid managed care plans (Molina, Coordinated Care, United Healthcare Community Plan) should verify formulary placement directly with their plan. Coverage terms can differ from fee-for-service Apple Health. Co-pays for Medicaid-covered generics in Washington are capped at $3 or less per prescription under federal rules outlined in the Medicaid drug rebate program guidelines [5].

Commercial Insurance and Prometrium in Washington

Most commercial insurers operating in Washington place generic micronized progesterone on Tier 1 or Tier 2. Plans sold through Washington Healthplanfinder (the state ACA exchange) are required to cover FDA-approved prescription drugs within each therapeutic class. Because micronized progesterone is the only FDA-approved oral natural progesterone, it typically faces minimal coverage barriers.

Specific insurer notes for Washington in 2026:

Premera Blue Cross lists generic micronized progesterone on Tier 1 with co-pays ranging from $5 to $15. Regence BlueShield places it on Tier 2 at $15 to $30. Kaiser Permanente Washington covers it as preferred generic with $10 to $20 co-pays. For brand-name Prometrium, expect Tier 3 co-pays of $40 to $75 at most plans, with some requiring prior authorization or step therapy through the generic first.

The North American Menopause Society (NAMS) 2022 position statement explicitly endorses micronized progesterone for endometrial protection and notes its favorable cardiovascular and breast safety profile compared to synthetic progestins [6]. This guideline support means appeals for coverage denials have a strong evidence foundation. The Women's Health Initiative (WHI) data showing increased breast cancer risk applied specifically to medroxyprogesterone acetate, not micronized progesterone, a distinction the E3N cohort study (N=80,377) reinforced by finding no significant breast cancer increase with micronized progesterone use over a mean 8.1-year follow-up [7][8].

Compounded Micronized Progesterone in Washington

Compounded micronized progesterone is available through licensed 503A compounding pharmacies in Washington. Average cost runs approximately $25 per month. This is legal under federal and Washington state law, provided the pharmacy holds a valid Washington State Department of Health compounding license and compounds pursuant to a patient-specific prescription.

Key distinctions matter here. A 503A pharmacy compounds individual prescriptions under state oversight [9]. A 503B outsourcing facility operates under direct FDA inspection and can produce larger batches without patient-specific prescriptions. Both operate legally in Washington. The Washington State Pharmacy Quality Assurance Commission regulates 503A pharmacies and requires compliance with USP <795> and USP <797> standards for non-sterile and sterile compounding respectively.

Compounded progesterone is not AB-rated to Prometrium. The FDA has issued guidance noting that compounded hormone preparations have not undergone the same bioequivalence testing as FDA-approved products [10]. Patients switching between brand/generic Prometrium and compounded micronized progesterone should discuss potency verification with their prescriber. The American College of Obstetricians and Gynecologists (ACOG) recommends FDA-approved formulations as first-line when available, reserving compounded products for patients who need doses or delivery routes not commercially available [11].

Some Washington patients choose compounded progesterone for specific dosage forms unavailable commercially. These include vaginal suppositories, topical creams, and sublingual troches. The cost advantage is real but comes with trade-offs in standardization and regulatory oversight.

Discount Programs and Savings Cards

Several pathways exist to reduce out-of-pocket costs in Washington.

Manufacturer savings programs. AbbVie (which acquired the Prometrium brand through the Solvay acquisition) has periodically offered co-pay savings cards for brand-name Prometrium. These cards typically reduce co-pays to $25 or less for commercially insured patients. They cannot be used with Medicare, Medicaid, or other federal healthcare programs per the federal Anti-Kickback Statute restrictions [12]. Check the manufacturer website directly for current card availability, as program terms change annually.

Pharmacy discount platforms. GoodRx, RxSaver, and similar discount card programs frequently show generic micronized progesterone priced between $15 and $35 at Washington pharmacies. These prices are negotiated cash rates, not insurance benefits, and can sometimes beat insured co-pays. Patients paying $30 co-pays through insurance may find $18 cash prices at Costco or Walmart using discount tools.

Patient assistance programs. For uninsured patients with household income below 200% of the federal poverty level, NeedyMeds and RxAssist maintain databases of manufacturer and foundation assistance programs. Washington's own Prescription Drug Assistance Foundation may offer additional state-specific resources [13].

340B pricing. Patients receiving care at federally qualified health centers (FQHCs) or other 340B-eligible entities in Washington may access micronized progesterone at significantly reduced prices. Washington has over 30 FQHCs operating across the state, particularly in rural and underserved areas. The 340B Drug Pricing Program requires manufacturers to provide outpatient drugs at discounted prices to eligible healthcare organizations [14].

Getting Prometrium via Telehealth in Washington

Washington state permits telehealth prescribing of Prometrium. No in-person visit is required for an initial prescription. The Washington Medical Commission allows clinicians licensed in Washington to prescribe Schedule IV and non-controlled medications through audio-visual telehealth encounters. Micronized progesterone is not a controlled substance, which removes additional prescribing barriers.

Telehealth platforms operating in Washington can prescribe Prometrium for both FDA-approved indications (secondary amenorrhea and endometrial protection with estrogen therapy). The Endocrine Society has published guidelines supporting telehealth management of hormone therapy, noting that routine HRT monitoring (symptom assessment, medication adjustment) is well-suited to virtual visits [15]. Baseline labs including a lipid panel and, in some protocols, an endometrial thickness assessment via ultrasound may still require in-person components.

Washington telehealth parity law (RCW 48.43.735) requires commercial insurers to reimburse telehealth visits at the same rate as in-person visits. This means the telehealth visit itself should not carry a higher co-pay than an equivalent office visit. Patients using telehealth should confirm their pharmacy preference at the time of the visit so the prescription routes to a convenient Washington location or a mail-order pharmacy licensed in the state.

How Prometrium Compares on Cost to Other Progestogens

Micronized progesterone is not the only option for endometrial protection, and cost differences can be significant.

Medroxyprogesterone acetate (Provera) generics cost $4 to $10 per month at most Washington pharmacies, making it the cheapest oral progestogen. But the WHI trial associated it with increased breast cancer risk when combined with conjugated equine estrogens, and the PEPI trial showed it blunted the HDL-raising effect of estrogen therapy [3][7]. The levonorgestrel IUD (Mirena) provides local endometrial protection and costs $800 to $1,000 upfront but lasts 5 to 8 years, translating to roughly $10 to $17 per month amortized. The AACE/ACE 2017 menopause guidelines recognize the levonorgestrel IUD as an option for endometrial protection during systemic estrogen therapy [16].

Norethindrone acetate (Aygestin) generics run $20 to $40 per month. Dydrogesterone (approved in Europe, not yet FDA-approved) is unavailable in Washington. Combination estrogen-progestogen products like Prempro or Activella carry their own pricing structures, typically $30 to $60 per month for generics.

At $45 average cash price for the generic, micronized progesterone occupies a middle position. Its cost-per-month is higher than medroxyprogesterone but lower than many combination products. The clinical safety advantages documented in the French E3N study and endorsed by NAMS often justify the incremental cost [6][8].

Filling Tips Specific to Washington Patients

Pharmacy pricing in Washington varies more than most patients expect. A few concrete strategies can reduce costs.

Compare at least three pharmacies before filling. Costco pharmacies (you do not need a membership to use the pharmacy in Washington) consistently rank among the lowest-cost options for generic micronized progesterone statewide. Mail-order pharmacies licensed in Washington may offer 90-day supplies at 2x the 30-day price, effectively cutting per-month cost by one-third.

Ask your pharmacist about the Washington Prescription Drug Program (WPDP), a state-administered discount program available to uninsured and underinsured residents. The program negotiates supplemental rebates that can lower costs below standard cash pricing.

For patients on continuous combined HRT regimens using 100 mg nightly, request a 90-day fill if your insurance allows it. For cyclical regimens (200 mg for 12 days per cycle), the actual pill count per month is lower, and your pharmacist can dispense exactly the quantity needed rather than a standard 30-count bottle. This small adjustment can save $10 to $15 per fill on cash-pay prescriptions.

Patients filling at military treatment facilities or VA pharmacies in Washington (Joint Base Lewis-McChord, Naval Station Everett) may access micronized progesterone at federal supply schedule pricing, often under $10 per month [17].
