Alprostadil (Caverject/MUSE) Cost in Arkansas 2026

What Does Alprostadil Cost in Arkansas Without Insurance?

The cash price for brand-name Caverject or MUSE at Arkansas retail pharmacies runs approximately $600 per month in 2026, matching the national manufacturer list price set by Pfizer and the generic manufacturers. That figure reflects a package of intracavernosal injection kits or urethral suppositories sized for a typical month of on-demand use. Individual vial pricing matters here: a single 20 mcg Caverject vial retails between $90 and $200 depending on the pharmacy, and men who use alprostadil only once or twice weekly may spend far less than the headline monthly figure.

Arkansas has three major pharmacy chains, Walgreens, CVS, and Walmart, plus independent compounding pharmacies concentrated in Little Rock, Fayetteville, and Fort Smith. Prices differ by as much as 30% across those locations. GoodRx coupons applied at Walmart in Arkansas have brought a single 20 mcg Caverject Impulse kit to roughly $95 per vial as of early 2026, which is a meaningful reduction for uninsured patients. The intraurethral MUSE 1000 mcg suppository (six-pack) has a street price near $350 at most Arkansas chains without a discount card.

Alprostadil (prostaglandin E1) was first approved for intracavernosal injection by the FDA in 1995 and for the urethral suppository form in 1996. [1] The landmark randomized trial by Linet and Ogrinc published in the New England Journal of Medicine showed that 94.8% of injection attempts produced erections sufficient for intercourse in men with organic erectile dysfunction, with a mean dose of 17.8 mcg. [2] That efficacy ceiling is why alprostadil remains a first-line option when oral phosphodiesterase-5 inhibitors fail or are contraindicated.

Patients with diabetes or post-prostatectomy ED, who are among the most likely to need alprostadil, [3] should request exact vial pricing from at least two local pharmacies before filling. Price transparency varies; calling the pharmacy directly often yields a cash-pay quote lower than what appears on online checkers.

Arkansas Medicaid Coverage for Alprostadil

Arkansas Medicaid covers alprostadil for refractory erectile dysfunction, but a prior authorization (PA) is required. The coverage is limited to cases where the prescriber documents that oral PDE-5 inhibitor therapy (sildenafil, tadalafil, or vardenafil) has failed or is medically contraindicated. The Arkansas Medicaid Preferred Drug List, administered through DHS Division of Medical Services, places alprostadil in a non-preferred tier requiring PA for most formulary benefit categories. [4]

Getting the PA approved typically takes three to seven business days. The prescriber must submit clinical notes confirming organic etiology, at least one prior PDE-5 inhibitor trial, and absence of contraindications such as significant hypotension or anatomical deformity. Arkansas Medicaid beneficiaries who qualify pay standard cost-sharing, which is generally $3 to $8 per prescription for preferred medications; the PA process determines whether alprostadil qualifies at that tier.

Men enrolled in Arkansas Medicaid managed care plans (Arkansas Total Care and Summit Community Care are the two active MCOs as of 2026) should verify formulary status separately, because MCO formularies may differ slightly from the fee-for-service PDL. [5] Calling the plan's pharmacy benefits number before the physician submits the PA avoids a mismatch between what the prescriber documents and what the MCO actually requires.

The American Urological Association guideline on erectile dysfunction states that "pharmacotherapy for ED should be discussed with patients for whom lifestyle modifications and risk-factor reduction have been insufficient," [6] which forms the clinical basis most prescribers use when writing PA letters for Arkansas Medicaid.

Is Compounded Alprostadil Legal in Arkansas?

Yes. Compounded alprostadil is legal in Arkansas when prepared by a licensed 503A pharmacy operating under state board of pharmacy oversight and federal USP standards. The FDA's framework for 503A compounding pharmacies, established under the Drug Quality and Security Act of 2013, allows patient-specific compounding of alprostadil provided the pharmacy holds a valid state license and the preparation is made pursuant to a valid prescription. [7]

Several Little Rock-area compounding pharmacies prepare alprostadil in both intracavernosal injection form (typically in a tri-mix base of alprostadil, papaverine, and phentolamine) and as a standalone solution. Compounded formulations are not FDA-approved finished drug products, so quality depends on pharmacy accreditation. Patients should confirm that the pharmacy holds PCAB (Pharmacy Compounding Accreditation Board) accreditation or equivalent state inspection status.

Cost is the main reason patients seek compounded alprostadil. A compounded 10 mcg/0.5 mL intracavernosal vial (30-day supply) from an Arkansas 503A pharmacy may cost as little as $0 under certain patient-assistance arrangements or between $60 and $150 cash-pay, compared with the $600 brand list price. [8] Tri-mix, which combines alprostadil with two additional vasoactive agents, is not available commercially and is exclusively a compounded preparation.

Telehealth prescribers operating in Arkansas can legally write prescriptions for compounded alprostadil, provided the prescriber holds a valid Arkansas medical license and a valid patient-prescriber relationship exists, consistent with Arkansas Code Annotated § 17-95-101 governing telemedicine. [9]

Which Insurance Plans Cover Alprostadil in Arkansas?

Coverage varies sharply. Medicare Part D covers alprostadil because it is classified as an injectable medication for a specific medical condition (erectile dysfunction refractory to other therapy) rather than a lifestyle drug under the Part D exclusion statute. [10] That distinction matters: Medicare explicitly excludes sildenafil and tadalafil for ED under 42 U.S.C. § 1395w-102(e)(2), but injectable alprostadil sits in a different regulatory category and has been covered by many Part D plans. Beneficiaries should check their plan's formulary at the Medicare Plan Finder tool, because tier placement and prior-authorization rules still vary by plan.

Commercial insurers in Arkansas, including Arkansas Blue Cross Blue Shield, Ambetter Arkansas (Centene), and QualChoice, list alprostadil on mid-tier formularies with prior authorization. QualChoice's 2025 commercial formulary placed Caverject on Tier 3 with a $60 to $90 copay per fill after PA. BCBS Arkansas requires documentation of PDE-5 inhibitor failure consistent with the AUA guideline criteria cited above. [6]

Employer-sponsored self-insured plans are governed by ERISA and set their own formulary rules. Some exclude erectile dysfunction treatments entirely. Employees should review their Summary of Benefits and Coverage document or contact HR before assuming coverage exists.

Veterans in Arkansas receiving care through the John L. McClellan Memorial Veterans' Hospital in Little Rock or the Fayetteville VA Medical Center may access alprostadil through the VA National Formulary if criteria are met. The VA formulary does list alprostadil as a non-formulary item requiring non-formulary justification in many cases, so a urologist's recommendation carries weight. [11]

Pfizer Savings Card and Discount Programs in Arkansas

Pfizer offers a Caverject savings card through its PfizerRxPathways program. Eligible commercially insured patients in Arkansas may pay as little as $0 to $25 per fill. The card is not valid for patients covered by Medicare, Medicaid, CHIP, or any other federal or state government program. Income-based eligibility caps apply. [12]

The Pfizer Patient Assistance Program (PAP) provides free Caverject to uninsured or underinsured patients who meet income guidelines, generally at or below 400% of the federal poverty level. Arkansas patients can apply directly through PfizerRxPathways online or via their prescriber's office.

Generic alprostadil (manufactured by Sandoz and Paddock/Perrigo) does not have a branded savings card, but GoodRx and RxSaver coupons apply and typically reduce the price at Walmart and Costco in Arkansas to the $90 to $120 range per vial. Costco's Fayetteville and Little Rock locations have historically offered the lowest cash price among major retailers in the state.

The table below summarizes the four primary cost pathways for alprostadil in Arkansas, ranked from lowest to highest likely out-of-pocket cost for a typical patient using the medication four times per month.

Arkansas Alprostadil Cost Pathways (4 uses/month, 2026 estimate)

| Pathway | Estimated Monthly OOP | |---|---| | Compounded tri-mix via 503A (cash-pay) | $60, $150 | | Brand Caverject + Pfizer savings card (commercially insured) | $0, $25 | | Generic alprostadil + GoodRx (uninsured) | $360, $480 | | Brand Caverject cash-pay (no discount) | ~$600 |

Patients with Arkansas Medicaid who receive PA approval will generally pay standard Medicaid cost-sharing ($3, $8), placing their cost below all rows in this table.

How to Get Alprostadil via Telehealth in Arkansas

Telehealth prescribing of alprostadil is legal in Arkansas. State law requires that a valid patient-prescriber relationship exist before a controlled or non-controlled prescription is issued, and alprostadil is not a scheduled controlled substance, which simplifies the process. Under the Arkansas Telemedicine Act (Act 788 of 2015, as amended), physicians must hold an active Arkansas medical license to prescribe to Arkansas residents. [13]

A standard telehealth visit for erectile dysfunction evaluation takes 20 to 45 minutes. The clinician reviews cardiovascular history (alprostadil is systemically absorbed in smaller amounts than oral PDE-5 inhibitors but still warrants cardiac screening), medication list, and prior treatment history. Men with a penile implant, Peyronie's disease causing severe curvature, or active urinary tract infection should defer to an in-person urologist.

The FDA label for Caverject specifies a starting dose of 1.25 to 2.5 mcg for neurogenic erectile dysfunction and 2.5 to 5 mcg for vasculogenic ED, titrated upward under medical supervision. [14] Telehealth providers in Arkansas typically require an initial in-person injection training session at a local clinic or with a nurse, because the intracavernosal injection technique requires demonstration. MUSE (intraurethral suppository) does not require injection training and is sometimes preferred for patients who are not comfortable with self-injection.

Post-prostatectomy patients represent a distinct group. A 2018 Cochrane review found that alprostadil significantly improved erectile function scores versus placebo in men after radical prostatectomy, with an odds ratio of approximately 7.5 for achieving intercourse. [15] Telehealth programs targeting this population are active in Arkansas through at least two HealthRX-affiliated providers.

Alprostadil Dosing, Forms, and Clinical Use in Arkansas

Alprostadil works by binding to prostaglandin EP2 and EP3 receptors in cavernosal smooth muscle, increasing cyclic AMP, reducing intracellular calcium, and producing smooth muscle relaxation and arterial dilation. [16] It acts locally, with peak effect within 5 to 20 minutes of intracavernosal injection and 10 to 30 minutes after MUSE administration.

The recommended maximum intracavernosal dose is 60 mcg per injection. The maximum recommended frequency is three times per week with at least 24 hours between doses, per the FDA label. [14] Exceeding these limits raises the risk of priapism, which is defined as erection lasting more than four hours and constitutes a urological emergency requiring prompt treatment. Patients must receive written instructions to go to an emergency department immediately if erection persists beyond four hours.

MUSE suppositories are available in four strengths: 125 mcg, 250 mcg, 500 mcg, and 1000 mcg. The intraurethral route produces lower peak cavernosal drug concentrations than injection, so efficacy rates are modestly lower. The MUSE Phase III trial (N=1,511) showed that 64.9% of MUSE-treated men had at least one successful intercourse attempt during the three-month treatment period, compared with 18.6% in the placebo group (P<0.001). [17]

The most common adverse effect of intracavernosal alprostadil is penile pain, reported in up to 37% of patients in controlled trials. [2] The incidence of priapism in controlled trials was approximately 1%. Prolonged erection (two to four hours, resolving spontaneously) occurred in about 4% of patients. These figures are from the original NEJM trial data, which remain the most cited efficacy and safety benchmark in the literature.

Comparing Alprostadil to Other ED Therapies on Cost in Arkansas

For context, oral sildenafil 20 mg (generic) costs approximately $1 per tablet at Walmart in Arkansas under GoodRx pricing. Tadalafil 5 mg daily (generic) runs about $15 to $25 per month. These oral agents are far cheaper than brand alprostadil but are contraindicated with nitrate medications and ineffective in men with severe vascular disease or complete neurological interruption post-prostatectomy. [18]

Tri-mix compounded injection, which contains alprostadil alongside papaverine and phentolamine, produces higher response rates in men who respond poorly to alprostadil alone, according to a 2019 review in the Journal of Sexual Medicine. [19] Because tri-mix has no commercial equivalent, its lower compounded cost ($60 to $150/month) makes it the most economical injectable option for uninsured Arkansas patients.

Penile prosthesis surgery, the definitive treatment for medication-refractory ED, carries an average hospital cost of $22,000 to $34,000, making alprostadil a substantially less expensive long-term management strategy for most patients. [20]

Clinicians at Arkansas urology practices in Little Rock and Fayetteville generally follow the AUA Sexual Medicine guideline recommendation to offer alprostadil as a second-line therapy after PDE-5 inhibitor failure, and as a first-line therapy when oral agents are contraindicated. [6] Documenting that sequence is exactly what Arkansas Medicaid and commercial insurers require for PA approval.
