Alprostadil (Caverject/MUSE) Cost in Oregon 2026

What Is Alprostadil and How Does It Work?

Alprostadil is a synthetic prostaglandin E1 (PGE1) that relaxes smooth muscle in penile arterial walls, producing an erection within 5 to 20 minutes of administration [1]. Two FDA-approved delivery forms exist: Caverject (intracavernosal injection, 5 to 40 mcg per dose) and MUSE (medicated urethral system for erection, 125 to 1 to 000 mcg suppository) [2]. Both are prescription-only in the United States.

The landmark Linet et al. trial published in the New England Journal of Medicine (1996, N=296) showed that intracavernosal alprostadil produced a successful erection in 94% of injection attempts versus 18% of placebo attempts, with a mean duration of 30 minutes at the 20-mcg dose [3]. That efficacy profile is why alprostadil remains a second-line standard of care when oral phosphodiesterase-5 inhibitors fail or are contraindicated [4].

The FDA label for Caverject specifies a maximum frequency of one injection per 24 hours and no more than three injections per week [2]. MUSE carries the same 24-hour minimum interval [5]. Oregon clinicians generally follow the American Urological Association (AUA) Erectile Dysfunction Guideline, which positions alprostadil as the preferred second-line injectable therapy after PDE5 inhibitor failure [6].

Alprostadil does not require sexual stimulation to initiate an erection, which distinguishes it mechanically from PDE5 inhibitors such as sildenafil or tadalafil [4]. That difference matters for patients with severe arteriogenic or neurogenic ED who generate inadequate response to oral agents even with stimulation [7].

Alprostadil Cash-Pay Price in Oregon in 2026

The average cash-pay price for brand or generic alprostadil at Oregon retail pharmacies in 2026 is approximately $600 per month. Prices vary by dose, quantity, and dispensing pharmacy.

Caverject Impulse (Pfizer, 10 mcg or 20 mcg dual-chamber cartridge) lists near $75 to $100 per single-dose kit at many Oregon chains. Buying a six-kit supply pushes the monthly cost toward $450 to $600 before any discount [8]. Generic alprostadil injection formulations approved by the FDA carry similar sticker prices because manufacturing complexity limits competition [2].

MUSE urethral suppositories (Meda Pharmaceuticals) run roughly $50 to $70 per suppository at Oregon retail, meaning monthly costs at one to two uses per week reach $200 to $560 depending on dose strength (125, 250, 500, or 1 to 000 mcg) [5].

GoodRx and similar discount aggregators sometimes list alprostadil 20 mcg injection below $300 for a supply of six kits at select Oregon pharmacies, but availability fluctuates [9]. Patients should call the specific Portland, Eugene, Salem, or Bend pharmacy before driving in, because alprostadil is not stocked universally. Several independent compounding-adjacent retail pharmacies in Portland maintain better inventory than big-box chains.

Oregon Medicaid (Oregon Health Plan) Coverage

Oregon Medicaid, called the Oregon Health Plan (OHP), covers alprostadil with prior authorization when the prescribing clinician documents refractory erectile dysfunction, meaning the patient has tried and failed at least one oral PDE5 inhibitor at an adequate dose and duration [10].

The OHP Pharmacy and Therapeutics Committee classifies alprostadil as a covered benefit under the Prioritized List of Health Services when it appears on or above the funded line for sexual dysfunction treatment [10]. Prior authorization requests submitted through OHP's standard PA portal typically require documentation of the failed PDE5 inhibitor trial, diagnosis code N52 (male erectile dysfunction), and the prescribing provider's NPI number [10].

OHP members enrolled through Coordinated Care Organizations (CCOs) such as CareOregon, PacificSource Community Solutions, or Trillium Community Health Plan may face CCO-specific formulary steps, but the underlying OHP coverage framework applies statewide [10]. If a CCO denies the PA, Oregon law provides a right to internal appeal within 10 calendar days and an expedited external review within 72 hours for urgent situations [10].

Veterans in Oregon receiving care through the VA Portland Health Care System or the Roseburg VA may access alprostadil through the VA national formulary, which covers intracavernosal alprostadil for documented vasculogenic or neurogenic ED following a urology or primary care evaluation [11].

Compounded Alprostadil in Oregon: Legality and Cost

Compounded alprostadil is legal in Oregon when prepared by a 503A pharmacy operating under a valid state pharmacy license and complying with USP Chapter 797 sterile compounding standards [12]. Oregon Board of Pharmacy rules require 503A pharmacies to compound only pursuant to a valid patient-specific prescription from a licensed prescriber [12].

Cost drops sharply with compounded formulations. An Oregon 503A pharmacy may supply compounded alprostadil injection (typically 10 to 40 mcg per dose in a multi-dose vial) for roughly $80 to $150 per month, compared to $600 for the branded kit. Some telehealth practices that include compounding pharmacy partnerships quote out-of-pocket costs near zero when bundled with a membership model, though patients should verify pharmacy licensure independently [12].

The FDA distinguishes 503A pharmacies (patient-specific compounding, state-regulated) from 503B outsourcing facilities (bulk compounding, federally registered). Alprostadil is not on the FDA's Current Drug Shortage List as of early 2026, which means 503B outsourcing facilities generally may not compound it for office use without a shortage justification [13]. Oregon 503A pharmacies face no such restriction for patient-specific prescriptions [12].

Papaverine-phentolamine-alprostadil tri-mix is a commonly compounded injectable combination that some Oregon urologists and sexual medicine specialists prescribe when mono-agent alprostadil produces inadequate rigidity or intolerable pain. Tri-mix is not FDA-approved as a combination, so it is only available from 503A pharmacies and carries a lower cost per injection than branded mono-agent alprostadil [14].

Patients should confirm that any Oregon compounding pharmacy holds an active license via the Oregon Board of Pharmacy license verification tool before filling a compounded prescription [12].

Telehealth Prescribing of Alprostadil in Oregon

Oregon law fully permits telehealth prescribing of alprostadil for erectile dysfunction. Prescribers licensed in Oregon may conduct a synchronous audio-video visit, establish a valid patient-prescriber relationship, and issue a prescription for Caverject, MUSE, or compounded alprostadil without an in-person physical examination, provided they can obtain an adequate history and review relevant records [15].

Oregon adopted permanent telehealth prescribing rules in 2023 that removed the pre-COVID requirement for an initial in-person visit for most non-controlled substances [15]. Alprostadil is not a controlled substance under the DEA Controlled Substances Act, so none of the Ryan Haight Act restrictions that apply to Schedule II-V drugs affect alprostadil telehealth prescribing [16].

A telehealth consultation for alprostadil in Oregon typically covers: ED history and prior treatment trials, cardiovascular risk screening (because sexual activity carries exertion-equivalent cardiac demand), a review of contraindications including penile anatomical abnormalities or anticoagulant use, and injection or suppository technique instruction via video [6]. First-time users are generally advised to administer their initial dose under clinical supervision given the risk of priapism, hypotension, and syncope [2].

HealthRX clinicians licensed in Oregon can prescribe alprostadil or compounded tri-mix during a single telehealth encounter for most patients who bring prior ED treatment records to the visit.

Insurance Coverage for Alprostadil in Oregon

Private insurance coverage for alprostadil in Oregon varies by plan. The ACA requires coverage of preventive services but does not mandate coverage of ED treatments. Most Oregon commercial plans treat alprostadil as a specialty or non-preferred drug that may require prior authorization [17].

Major Oregon commercial insurers including PacificSource, Regence BlueCross BlueShield of Oregon, Moda Health, and Kaiser Permanente Northwest each maintain their own formularies. Patients should check the plan's drug formulary (available on the insurer's member portal) and look for alprostadil under Tier 3 or Tier 4, or under a specialty tier [17]. A PA requirement appears on most plans and generally mirrors the OHP criteria: documented PDE5 inhibitor failure at an adequate dose [17].

Medicare Part D plans cover alprostadil only when it appears on a specific plan's formulary. CMS does not exclude alprostadil from Medicare Part D the way it excludes drugs used "for the treatment of sexual dysfunction or impotence" under certain categories, but plan-level coverage is inconsistent [18]. Oregon Medicare Advantage enrollees should call their plan's pharmacy benefit line to confirm formulary status before filling [18].

The AUA Erectile Dysfunction Guideline (2018, amended 2024) states: "Physicians should discuss with patients the efficacy, safety, and cost of all available treatment options and help patients select a therapy consistent with their values and preferences" [6]. That standard supports documentation showing that cost-driven access barriers were discussed, which strengthens a prior authorization appeal if an insurer denies coverage.

Discount Programs and Savings Options for Oregon Patients

Several cost-reduction pathways exist for Oregon residents paying out-of-pocket or facing high copays.

Pfizer's patient assistance program covers Caverject for commercially insured patients with high cost-sharing and for uninsured patients below an income threshold. Oregon residents can apply through the Pfizer RxPathways portal [19]. Income eligibility for the uninsured tier is typically set at or below 400% of the federal poverty level, which in 2026 corresponds to roughly $58,320 for a single adult [19].

GoodRx, RxSaver, and Blink Health publish discount coupons for alprostadil that override the list price at participating Oregon pharmacies. The effective price varies by pharmacy and fluctuates weekly, but discounts of 30% to 50% off the retail list price are common at chains including Walgreens, Rite Aid, and Fred Meyer locations in Portland, Eugene, and Salem [9]. Using a GoodRx coupon means paying cash and forfeiting insurance credit toward the deductible for that prescription.

Oregon Prescription Drug Program (OPDP), administered by the Oregon Department of Administrative Services, offers a free discount card available to all Oregon residents regardless of income or insurance status. OPDP negotiates rates with a pharmacy benefit manager and may produce savings on alprostadil at participating pharmacies, though the discount is typically smaller than GoodRx for specialty items [20].

Clinics affiliated with Oregon Health and Science University (OHSU) and federally qualified health centers (FQHCs) in Portland, Eugene, and Medford may access 340B drug pricing for eligible low-income patients, which can reduce alprostadil cost substantially at the dispensing pharmacy [21].

Comparing Caverject vs. MUSE: Cost and Efficacy in Context

The cost difference between Caverject (injection) and MUSE (suppository) in Oregon is modest at list price, but efficacy data favor injection. Linet et al. (NEJM 1996) documented 94% successful erection rates with intracavernosal alprostadil at 20 mcg [3]. By contrast, the key MUSE trial (Padma-Nathan et al., NEJM 1997, N=1,511) showed in-clinic success in 65.9% of MUSE users at the 1,000-mcg dose versus 18.6% placebo [22].

The AUA guideline notes that MUSE is associated with urethral burning in up to 36% of users and that intracavernosal injection achieves higher penile tissue bioavailability than transurethral delivery [6]. For patients unwilling to self-inject, MUSE remains a clinically validated option despite lower efficacy. The cost per successful erection favors Caverject when accounting for efficacy differences [3, 22].

Patients new to either formulation should receive hands-on technique instruction. Improper injection technique is the leading cause of local side effects including ecchymosis, pain, and fibrosis [2]. Oregon urology practices at OHSU and private groups in Portland typically offer a supervised first-injection clinic visit before the patient self-administers at home.

Side Effects That Affect Adherence and Dosing Cost

Understanding side effects matters for cost planning because patients who experience pain or priapism often abandon treatment, wasting medication already purchased.

Penile pain occurs in roughly 30% to 40% of intracavernosal alprostadil users at doses above 10 mcg, per the Caverject FDA label [2]. Priapism (erection lasting more than 4 hours) occurs in under 1% of users when doses are titrated under clinical supervision, but requires emergency treatment with aspiration or intracavernosal phenylephrine [2]. Oregon patients should have a written action plan for priapism management before self-injecting at home.

Hypotension occurs in approximately 2% of MUSE users and has been documented in partners exposed to alprostadil through vaginal absorption, which is why condom use is recommended during MUSE-assisted intercourse with pregnant partners [5]. These safety requirements do not change the price of the medication but do affect total cost of care if an emergency room visit for priapism is needed [2].

Starting at the lowest effective dose reduces both side-effect risk and per-use cost. The Caverject label recommends beginning at 2.5 mcg for neurogenic ED and 5 to 10 mcg for vasculogenic ED, titrating upward under supervision [2]. Patients who skip supervised titration and self-start at higher doses spend more per month and face higher risk of complications requiring medical care [2].

Step-by-Step Cost Optimization for Oregon Patients

Oregon patients aiming to minimize alprostadil costs should work through a specific sequence.

First, confirm the diagnosis formally with a licensed Oregon prescriber. Self-diagnosis without a valid prescription prevents access to any discount program [6]. A telehealth visit with an Oregon-licensed clinician covers this step efficiently.

Second, check Oregon Health Plan eligibility at OregonHealthCare.gov. Adults with household income at or below 138% FPL qualify for OHP standard, which covers alprostadil with PA. That threshold is approximately $20,120 for a single adult in 2026 [10].

Third, if commercially insured, run the plan's formulary check and submit a PA request with documentation of prior PDE5 inhibitor failure. Include trial duration, dose, and reason for discontinuation [17].

Fourth, for uninsured patients or those with unacceptably high cost-sharing, ask the prescribing clinician to send the prescription to a licensed Oregon 503A compounding pharmacy for compounded alprostadil injection [12]. Monthly cost at many Oregon compounding pharmacies runs $80 to $150. Add the OPDP card for additional savings [20].

Fifth, compare GoodRx prices at three or more Oregon pharmacies before filling any cash-pay prescription. Prices differ by $50 to $150 between chains in the same city [9].
