Alprostadil (Caverject/MUSE) Cost in North Dakota: 2026 Pricing, Insurance, and Savings Guide

The 2026 price picture: package price matters more than "per month"

The clearest national benchmark is Pfizer's January 2026 price list. It lists Caverject Impulse at $172.58 for two 10 mcg systems and $222.23 for two 20 mcg systems. A carton of six Caverject vials lists at $661.58 for 20 mcg and $872.71 for 40 mcg [1]. These are wholesale acquisition cost figures, not a promise of what a North Dakota patient will pay. A pharmacy's retail price, an insurer's negotiated price, a deductible, and a discount-card price can all differ.

A June 24, 2026 GoodRx snapshot illustrates that difference. Nationally, it showed an average retail price of $791.32 and a coupon price of $675.93 for six 20 mcg Caverject vials. For six 40 mcg vials, it showed $1,050.72 retail and $883.55 with a coupon [2]. The same page warns that its displayed averages are not pharmacy-specific. A North Dakota resident should therefore enter a current Fargo, Bismarck, Grand Forks, Minot, or local rural ZIP code and verify the quote with the dispensing pharmacy.

MUSE should be priced separately rather than folded into a Caverject average. GoodRx's 2026 listing showed six 1000 mcg MUSE systems at about $567.98 retail or $477 with a coupon, with different prices for the 125, 250, and 500 mcg packages [3]. Availability and price can change. A quote is only comparable when the product, strength, quantity, and number of doses all match the prescription.

Caverject, Caverject Impulse, and MUSE are not interchangeable price units

Caverject is alprostadil powder reconstituted for intracavernosal injection. The current Caverject label lists single-dose vials that deliver 20 or 40 mcg after reconstitution [4]. Caverject Impulse is a dual-chamber, single-dose syringe system that delivers up to 10 or 20 mcg [5]. MUSE is a single-use applicator that places a 125, 250, 500, or 1000 mcg alprostadil suppository in the urethra [6].

Those differences explain why a single "alprostadil monthly cost" can mislead. Two Impulse systems are two treatment systems, while a six-vial Caverject carton contains six single-use vials. The prescribed strength is not necessarily the administered dose, and unused drug in a single-dose product is discarded. MUSE doses use much larger microgram numbers because the route is different; its numbers should never be compared directly with injection doses.

Clinical evidence also differs by route. In the major intracavernosal program, men reported being able to have sexual activity after 94% of injections during a six-month self-injection study, and the activity was rated satisfactory after 87% of injections [7]. In a double-blind MUSE study, 64.9% of men randomized to active treatment after responding during clinic titration reported successful intercourse at least once at home, versus 18.6% with placebo [8]. These results describe selected study populations and do not predict an individual's response.

Does North Dakota Medicaid cover alprostadil for erectile dysfunction?

No. The current North Dakota Medicaid member handbook lists erectile dysfunction medications among non-covered prescriptions [9]. That directly supports the ED coverage answer and is more reliable than inferring coverage from a general preferred-drug list.

The exclusion is tied to use for erectile dysfunction. Alprostadil also exists in hospital formulations used for very different indications, including maintaining ductus arteriosus patency in certain newborns. Those products, doses, settings, and billing rules are not substitutes for Caverject or MUSE. A hospital claim for neonatal alprostadil should not be used to imply that North Dakota Medicaid covers outpatient Caverject for ED.

Patients should also avoid assuming that another device is covered simply because the drug is not. North Dakota directs members and providers to verify a specific service or supply before receiving it [9]. The prescriber or enrolled DME supplier can check the exact code and authorization rules.

Medicare and commercial insurance in North Dakota

Basic Medicare Part D excludes agents when they are used to treat sexual or erectile dysfunction. The CMS Part D benefit manual states that an ED drug can meet the Part D definition only when used for an FDA-approved, medically accepted indication other than sexual or erectile dysfunction [10]. For Caverject or MUSE prescribed for ED, a patient should expect a basic Part D exclusion unless the plan offers some separate enhanced benefit. The annual Part D out-of-pocket cap does not convert an excluded drug into a covered drug.

Commercial coverage cannot be summarized safely by naming a North Dakota carrier. Formularies vary by employer group and by the exact plan, even under the same insurer. Some plans exclude ED drugs; others cover a limited quantity or require prior authorization. The fastest reliable check is to ask the plan or pharmacy about the exact NDC and indication, then request these five items:

1. Whether the drug is covered for the prescribed indication.
2. Whether prior authorization, step therapy, or a quantity limit applies.
3. The cost before and after the deductible.
4. Whether the chosen pharmacy is in network.
5. Whether the insurance price or a cash-discount price is lower.

The 2018 AUA erectile dysfunction guideline does not require every patient to fail an oral drug before learning about injections or intraurethral therapy. It emphasizes shared decision-making and informing patients about all non-contraindicated treatment modalities [11]. An insurer may still impose its own utilization rules, but those rules should be verified in the member's current plan documents rather than presented as universal medical policy.

Are compounded alprostadil, bimix, or trimix automatically cheaper?

No defensible statewide price can be assigned to a compounded prescription. The formula, concentration, vial volume, beyond-use date, shipping, supplies, and prescribed frequency all affect cost. A quote for compounded trimix is also not a price quote for FDA-approved Caverject or MUSE.

Compounded products can serve an individual clinical need, but they are not FDA-approved. FDA explains that it does not review them before marketing for safety, effectiveness, or quality [12]. Under section 503A, compounding generally must be based on a valid prescription for an identified patient, and federal law restricts regular compounding of products that are essentially copies of commercially available drugs [13]. A prescriber and pharmacist should determine whether a compounded formulation is appropriate for the individual patient rather than treating it as an automatic low-cost substitute.

Before paying an online or mail-order pharmacy, verify that it requires a prescription, provides a reachable pharmacist, identifies the dispensing pharmacy, and is authorized to dispense into North Dakota. Ask for the exact ingredients and concentration, storage instructions, beyond-use date, total delivered cost, and the process for reporting a temperature excursion or product-quality concern. Do not compare prices until those details match.

Telehealth can start the evaluation, but Caverject training remains in person

North Dakota law permits an appropriate telemedicine evaluation, but it does not make a questionnaire-only prescription sufficient. The current Century Code requires a bona fide relationship and an evaluation equivalent to an in-person examination; a static online questionnaire or audio-only conversation does not meet that standard [14]. The clinician must also be authorized to care for a patient located in North Dakota.

For Caverject, the FDA label adds a practical limit: the first injections and dose titration take place in the health care provider's office, and the patient must be trained before home self-injection [4]. Telehealth can support screening, follow-up, coverage work, and coordination, but it does not erase the labeled in-office titration requirement.

This distinction matters for total cost. A patient may need to budget for the evaluation, an office titration visit, the medicine, syringes and needles not included with Caverject vials, sharps disposal, and follow-up. Caverject Impulse packages include a different delivery system, so supply needs should be confirmed from the exact prescription and package.

Dosing and storage details that affect waste and cost

Caverject dosing is individualized to the lowest effective dose. The FDA-published Caverject labeling starts titration at 2.5 mcg for vasculogenic, psychogenic, or mixed ED and at 1.25 mcg for pure neurogenic ED. It recommends no more than three home injections per week and at least 24 hours between doses [4]. These are label instructions, not a personalized dose recommendation.

Storage instructions differ by product and strength. Caverject 20 mcg vials are stored at controlled room temperature. Caverject 40 mcg vials are refrigerated until dispensed, then may be stored at or below 25°C for up to three months or until expiration, whichever comes first. After reconstitution, Caverject vial solution must be used within 24 hours at or below 25°C and should not be refrigerated or frozen [4]. Caverject Impulse is stored at controlled room temperature before mixing; its reconstituted solution can be kept for up to 24 hours at 2°C to 25°C [5].

MUSE unopened foil pouches are refrigerated at 2°C to 8°C, but the label permits room-temperature storage at 20°C to 25°C for up to 14 days and warns against temperatures above 30°C [6]. Those facts correct the common but incomplete statement that every alprostadil product must always be refrigerated.

Seek emergency care for an erection lasting more than four hours. The Caverject label also warns about penile fibrosis, hypotension, and injection-site bleeding, especially with anticoagulants [4]. In the large intracavernosal study, priapism occurred in 1% of men and penile pain occurred after 11% of injections, although half of participants reported pain at least once [7]. These figures are study results, not a forecast for an individual.

A practical North Dakota price-check sequence

Start with the exact prescription. Record the brand or product, strength, package quantity, NDC, intended doses per month, and any required supplies. Then compare the insurer's price with at least two local cash quotes and one current discount-card quote. Ask whether the quote includes the full package and whether the pharmacy can actually order it.

Next, check assistance without assuming a Caverject copay card exists. Pfizer's current Caverject page directs patients to Pfizer RxPathways, which screens eligible patients for insurance support, copay help, or medicine at a savings; it does not promise that every applicant or every Caverject prescription qualifies [15]. Government-insured patients should confirm program eligibility directly rather than relying on old coupon language.

Finally, compare total treatment cost, not just the drug sticker price. Include office titration, follow-up, injection supplies, shipping, discarded single-dose product, and the number of usable doses. Recheck the quote before each refill because pharmacy inventory, discount contracts, and plan adjudication can change.
