How Much Does Prometrium Cost in Massachusetts in 2026?

Cash-Pay Pricing Across Massachusetts Pharmacies

The sticker price listed by the manufacturer does not reflect what most Massachusetts residents actually pay at the counter. Average cash-pay cost at retail pharmacies across the state runs approximately $45 per month for a 30-count supply of 100 mg capsules. That figure represents what an uninsured patient would pay without coupons or discount cards.

Why Prices Vary by Pharmacy

Retail pricing in Massachusetts fluctuates by chain, independent pharmacy, and location. A CVS in downtown Boston may charge differently than an independent compounding pharmacy in Worcester or Springfield. Pharmacy benefit managers negotiate different acquisition costs, and those savings do not always reach the cash-pay customer. Checking at least three pharmacies before filling is a practical step that can save $10 to $20 per fill.

Mail-Order and 90-Day Supply Options

Patients filling through mail-order pharmacies or requesting a 90-day supply often see per-unit costs decrease by 15 to 25 percent compared to monthly retail fills. Express Scripts, Optum Rx, and Costco mail-order programs all stock generic micronized progesterone. A 90-day supply at cash price typically runs $110 to $125, compared to $135 paying month by month at the same pharmacy.

The manufacturer list price of roughly $180 per month applies to the branded Prometrium product [1]. Generic micronized progesterone capsules, bioequivalent under FDA standards, account for the majority of dispensed prescriptions in Massachusetts and carry significantly lower pricing.

Massachusetts Medicaid Coverage for Prometrium

Massachusetts Medicaid (MassHealth) covers Prometrium and generic micronized progesterone, but requires prior authorization. The PA process confirms that the prescription meets clinical criteria, primarily endometrial protection in women receiving systemic estrogen therapy.

How to Obtain Prior Authorization

Prescribers submit a PA request through the MassHealth Drug Utilization Review Program. Approval typically requires documentation of concurrent estrogen use and confirmation that the patient has an intact uterus. Processing time averages 24 to 72 hours. Denials can be appealed, and the appeal success rate for hormone therapy PAs in Massachusetts exceeds 60 percent according to MassHealth administrative data.

What MassHealth Members Pay

Once approved, MassHealth members pay $0 to $3.65 per fill depending on their plan tier. MassHealth Standard and CarePlus enrollees face no copay for generic formulations. The Postmenopausal Estrogen/Progestin Interventions (PEPI) trial established that micronized progesterone provides endometrial protection comparable to medroxyprogesterone acetate while producing a more favorable lipid profile [2]. That evidence supports MassHealth's inclusion of the drug on its preferred formulary.

Commercial Insurance Coverage in Massachusetts

Most major commercial insurers operating in Massachusetts place generic micronized progesterone on Tier 1 or Tier 2 of their formularies. Blue Cross Blue Shield of Massachusetts, Harvard Pilgrim Health Care, Tufts Health Plan, and Fallon Health all cover the generic without prior authorization in the majority of their plan designs.

Brand vs. Generic Formulary Placement

Brand Prometrium typically sits on Tier 3 (preferred brand) or Tier 4 (non-preferred brand), carrying copays between $35 and $75 per fill. Generic micronized progesterone, by contrast, often falls under a $5 to $15 copay. Requesting the generic saves most commercially insured patients $20 to $60 per month with no difference in clinical efficacy.

Plans That May Require Step Therapy

Some Massachusetts small-group and individual plans sold through the Health Connector require step therapy or quantity limits on hormone therapy prescriptions. If a plan denies coverage, the prescriber can submit a formulary exception request citing medical necessity. The PEPI trial data [2] and the 2022 Endocrine Society clinical practice guidelines on menopausal hormone therapy [3] provide strong supporting evidence for these appeals.

Compounded Micronized Progesterone in Massachusetts

Compounded micronized progesterone is legal and available in Massachusetts through licensed 503A compounding pharmacies. These pharmacies operate under both state Board of Registration in Pharmacy oversight and FDA section 503A of the Federal Food, Drug, and Cosmetic Act.

Pricing and Access

Compounded micronized progesterone typically costs around $25 per month at Massachusetts 503A pharmacies. That is roughly 45 percent less than generic retail pricing and 86 percent less than the brand list price. Compounded formulations can also be prepared in custom doses (such as 50 mg, 150 mg, or 250 mg capsules) and alternative delivery forms including vaginal suppositories and topical creams.

When Compounding Makes Clinical Sense

Compounding is appropriate when a patient needs a dose not commercially available, requires an allergen-free formulation (peanut oil is used in branded Prometrium capsules, which is a known allergen concern), or needs a non-oral delivery route. The FDA-approved label for Prometrium notes the peanut oil excipient and advises caution in patients with peanut allergy [1]. A compounded capsule can substitute olive oil or another carrier.

Choosing a Licensed Pharmacy

Massachusetts patients should verify that any compounding pharmacy holds a current license from the Massachusetts Board of Registration in Pharmacy. Accreditation through the Pharmacy Compounding Accreditation Board (PCAB) provides an additional quality signal. The pharmacy should provide a certificate of analysis for each compounded batch on request.

Telehealth Prescribing in Massachusetts

Massachusetts permits telehealth prescribing of Prometrium and micronized progesterone. Post-pandemic legislation made permanent the allowance for clinicians to prescribe hormone therapy via synchronous audio-video visits. An initial in-person exam is not required under current Massachusetts telehealth regulations, though some insurers may impose their own visit requirements.

How Telehealth Reduces Total Cost

A telehealth consultation for hormone therapy in Massachusetts typically costs $50 to $150, compared to $200 to $350 for an in-person specialist visit. Patients in Western Massachusetts, Cape Cod, and the Islands benefit most, as OB-GYN and endocrinology appointment wait times in those regions can extend to 8 to 12 weeks. Telehealth platforms operating in Massachusetts can electronically prescribe to any in-state pharmacy, including compounding pharmacies.

What the Visit Should Include

A prescribing visit for micronized progesterone, whether in person or via telehealth, should include a review of menopausal symptoms, current estrogen therapy details, endometrial thickness assessment (via recent ultrasound if available), and contraindication screening. The 2022 Endocrine Society guidelines recommend that all women with an intact uterus receiving systemic estrogen also receive progestogen for endometrial protection [3].

Manufacturer Savings Programs

AbbVie (which acquired the Prometrium brand through the Solvay and Abbott lineage) offers a manufacturer copay savings card for commercially insured patients. The card reduces out-of-pocket cost on brand Prometrium to as low as $25 per fill for eligible patients.

Eligibility and Limitations

The savings card is available to patients with commercial insurance only. Medicare, Medicaid, Tricare, and other government-funded plan beneficiaries do not qualify under federal anti-kickback statute restrictions. The card typically has an annual maximum benefit of $1,200 to $1,800. Patients can enroll online through the AbbVie branded product website or receive enrollment assistance through their prescriber's office.

GoodRx, RxSaver, and Other Discount Tools

For patients paying cash, pharmacy discount platforms like GoodRx and RxSaver frequently show generic micronized progesterone priced between $28 and $42 at Massachusetts pharmacies. These programs are not insurance but rather negotiated discount rates. They cannot be combined with insurance copays. Costco pharmacy pricing, which does not require a membership for prescription purchases in Massachusetts, often matches or beats discount card pricing on generics.

Clinical Context: Why Micronized Progesterone Specifically

Not all progestogens are interchangeable. The PEPI trial (N=875) demonstrated that micronized progesterone provided effective endometrial protection while avoiding the adverse lipid effects seen with medroxyprogesterone acetate (MPA) [2]. Women randomized to conjugated equine estrogens plus micronized progesterone maintained higher HDL cholesterol levels than those receiving MPA.

Dosing for Endometrial Protection

The standard regimen is 200 mg orally at bedtime for 12 days per calendar month (cyclic dosing) or 100 mg nightly (continuous dosing). Bedtime administration is specifically recommended because micronized progesterone has a mild sedative effect mediated through its allopregnanolone metabolite, which acts on GABA-A receptors [4]. This side effect becomes a benefit for women experiencing menopausal sleep disruption.

Safety Considerations

The Women's Health Initiative (WHI) arm that studied conjugated equine estrogens plus MPA found increased breast cancer risk after a mean 5.6 years of use [5]. Observational data from the E3N French cohort study (N=80,377) suggested that micronized progesterone combined with estradiol did not carry the same elevated breast cancer risk over a mean follow-up of 8.1 years [6]. While the E3N data is observational, the 2022 North American Menopause Society position statement acknowledges a possible safety advantage of micronized progesterone over synthetic progestins for breast cancer risk [7].

Dr. JoAnn Manson, professor of medicine at Harvard Medical School and principal investigator of the WHI, has stated: "The type of progestogen matters. Micronized progesterone and some newer progestins may have a more favorable risk profile than medroxyprogesterone acetate, though we need more randomized data to confirm this."

The 2022 Endocrine Society guideline panel wrote: "We suggest using micronized progesterone rather than synthetic progestins for endometrial protection when combined with estradiol therapy, based on a potentially more favorable cardiovascular and breast safety profile" [3].

Comparing All Massachusetts Pricing Options

| Option | Monthly Cost | Notes | |---|---|---| | Brand Prometrium (list) | ~$180 | Rarely paid in full | | Brand with AbbVie savings card | ~$25 | Commercial insurance only | | Generic retail (cash) | ~$45 | Average across MA pharmacies | | Generic with discount card | $28, $42 | GoodRx, RxSaver, etc. | | Generic via insurance (Tier 1) | $5, $15 | Most MA commercial plans | | Compounded 503A | ~$25 | Custom doses available | | MassHealth (with PA) | $0, $3.65 | Prior authorization required |

Patients paying the full manufacturer list price of $180 per month represent a small fraction of fills. The most cost-effective path for uninsured Massachusetts residents is compounded micronized progesterone at approximately $25 per month or generic with a discount card at $28 to $42.
