Average Cost of Naltrexone Injection for 2026

Our research team built a weighted comparative breakdown model that combines cash-pay data from national pharmacy and specialty-drug pricing databases, published CPT-code fee schedules for the clinical services surrounding the injection, Alkermes’ own program terms for Vivitrol, and public SAMHSA and state funding documentation. This methodology lets us calculate realistic cost ranges by category instead of one misleading national average. The average cost of a naltrexone injection (Vivitrol) is $1,000 to $2,500 per monthly shot for the medication alone, and total out-of-pocket cost typically climbs another $100 to $600 or more per visit once pre-injection testing, the clinical visit, and the administration fee are added. The trend across nearly every table below points the same direction: where and how a patient accesses treatment changes the total bill almost as much as the medication itself.

Average Cost of Naltrexone Injection by Pre-Induction Assessment Protocols

Before a physician can legally administer the first Vivitrol injection, guidelines require confirming a patient is completely opioid-free, a clinical vetting process with its own cost well before the shot itself. The table below breaks down what that mandatory workup typically runs.

Pre-Induction Requirement Typical Cash Cost What Drives the Cost Why It’s Required
Urine drug screen, point-of-care (in-office cup test) $20 to $50 Rapid immunoassay cup plus staff time to read the result Confirms no opioids are detectable before proceeding to a naloxone challenge
Urine drug screen, lab-based with confirmatory testing $50 to $350 Lab processing, plus confirmatory GC-MS testing when a screen is borderline Higher accuracy for recent or ambiguous opioid use
Comprehensive metabolic or liver function panel $15 to $320 Direct-access labs price near the low end; hospital-billed panels price near the high end Vivitrol carries a labeled warning for potential liver injury, so baseline liver function must be confirmed
Naloxone challenge test (monitored in-office procedure) $75 to $300, typically billed as part of the induction visit rather than a separate line item Cost of the naloxone dose itself plus 30 to 60 minutes of monitored physician or nursing time Confirms a patient will not go into precipitated withdrawal before the first injection
Pregnancy test, where applicable $10 to $50 Standard point-of-care urine test Routine screening before induction at most clinics
Physical exam or induction visit (physician or NP) $100 to $500 Prescriber’s credential and visit length Covers the clinical judgment call on whether induction is safe to proceed
Combined pre-induction workup, self-pay total $250 to $900 or more, before the injection itself Sum of the components above, before any sliding-scale or insurance adjustment Reflects that the cost of “the shot” understates what getting to the shot actually requires

*the naloxone challenge does not carry its own standalone CPT billing code. Clinics typically fold it into the induction visit as monitored clinical time rather than itemizing it separately, so that range should be read as a bundled cost estimate rather than a published line-item price.

The data reveals that testing and monitoring, not the medication, is the most unpredictable part of this process for a self-pay patient. A family budgeting only for the injection itself can be caught off guard by $250 to $900 in pre-treatment costs that have to clear before a single dose is given.

Average Cost of Naltrexone Injection by Manufacturer Savings & Financial Aid Programs

Because Vivitrol is a brand-name injection with no generic equivalent, standard discount cards go only so far. Alkermes, the manufacturer, runs its own savings and assistance programs that work differently than a typical pharmacy coupon.

Program Who Qualifies Typical Savings What It Does Not Cover
Vivitrol Co-pay Savings Program Commercially insured or fully uninsured patients paying cash. Excludes anyone covered by Medicare, Medicaid, TRICARE, VA, or another government-funded program Up to $500 off per prescription, for up to 12 fills a year (up to $6,000 in savings annually) The clinical visit, testing, and administration fee are billed separately from the medication
Vivitrol2gether Patient Assistance Program (income-qualified) Uninsured patients who meet Alkermes’ published income criteria Can significantly reduce or, for some qualifying patients, eliminate the medication cost Requires enrollment paperwork and income verification, and approval is not automatic
SingleCare or GoodRx pharmacy discount cards Anyone, regardless of insurance status Can bring the cash price down to roughly $1,750 to $1,950 per vial Limited practical value since most Vivitrol doses are billed through the administering provider, not a retail pharmacy counter
State Medicaid coverage Medicaid enrollees in participating states Often reduces the medication cost to $0 or a small copay Coverage details, prior authorization rules, and formulary status vary by state
340B-priced nonprofit or FQHC pharmacy Patients treated at a qualifying 340B covered entity Deep discount off list price, often not published publicly Only available through specific clinic types, not standard private practices

The data reveals that stacking programs, rather than relying on one, is what actually closes the affordability gap. A patient who qualifies for the income-based assistance program can end up paying less for a year of Vivitrol than an insured patient paying commercial copays without ever touching the co-pay card.

Average Cost of Naltrexone Injection by Relapse Prevention & Long-Term Care Maintenance Cycles

Vivitrol requires a new injection roughly every 28 days, which turns a single treatment decision into a recurring monthly cost. The table below models what that looks like over a 3, 6, and 12-month stabilization period paying entirely out of pocket.

Treatment Length Number of Injections Medication Cost Range (Self-Pay) Administration & Visit Fees (Estimated) Total Estimated Self-Pay Range
3-month stabilization cycle 3 $3,000 to $7,500 $300 to $1,800 $3,300 to $9,300
6-month cycle 6 $6,000 to $15,000 $600 to $3,600 $6,600 to $18,600
12-month cycle 12 $12,000 to $30,000 $1,200 to $7,200 $13,200 to $37,200

Clinical guidance commonly points to at least 12 months of Vivitrol as the recommended course, though the actual length is individualized and can run shorter or longer depending on a patient’s progress. In company-sponsored extension research, roughly half of patients who continued past the initial 6-month period remained in treatment for a full 18 months, which is part of why long-term financial planning matters as much as the first month’s bill.

The data reveals that the real cost of Vivitrol is rarely a single number. A family that only budgets for one injection can be unprepared for a total that is 6 to 12 times higher once a realistic treatment length is factored in, which is exactly why this is worth planning for before treatment starts, not after the first invoice arrives.

Average Cost of Naltrexone Injection by Region & Public Grant Availability

State Opioid Response grants, which totaled roughly $1.6 billion nationally in federal fiscal year 2024, require every grantee state to make all three FDA-approved opioid use disorder medications, including naltrexone, available regardless of a patient’s ability to pay. Michigan has used its SOR funding specifically to expand jail-based medication access and fund an Upper Peninsula opioid treatment program in a region that previously had none. The table below lays out the average self-pay per injection by US region.

Region Typical Self-Pay Cost Per Injection Key State & Public Funding Mechanisms Why the Price Differs
Northeast $1,200 to $2,600 State Medicaid MAT coverage; State Opioid Response (SOR) grant-funded clinics High pharmacy and clinic overhead in major metro markets pushes cash prices above the national average
Midwest (including Michigan) $1,050 to $2,150 Michigan’s SOR-funded jail-based MAT programs across dozens of county facilities; Michigan Opioid Healing and Recovery Fund (opioid settlement dollars); Medicaid MAT coverage Lower average overhead and more provider competition keep prices closer to the national floor
South $1,000 to $2,050 Federally Qualified Health Center (FQHC) sliding-scale MAT; 340B community health center pricing Lower cost of living overall, but thinner Medicaid expansion coverage in some states makes safety-net programs a bigger factor
West $1,100 to $2,450 State Medicaid OUD medication coverage; county behavioral health clinics Coastal metro costs run high, though inland cities in the same region often fall well below the regional average

*no single public dataset currently publishes Vivitrol-specific cash prices broken out by region. The ranges below apply documented metro-level pharmacy and specialty-drug cost variation to the national Vivitrol range established above, so they should be read as directional estimates rather than lab-verified regional averages.

The data reveals that public funding narrows the regional gap far more than geography alone would suggest. A patient in a high-cost metro area who qualifies for a state-funded program can often pay less than a self-pay patient in a lower-cost region who has no access to a grant-funded clinic. For families outside Michigan weighing the cost of a local provider against traveling for coordinated care, it’s worth pricing both the medication and the surrounding support (testing, aftercare, and follow-up) rather than the injection alone.

Average Cost of Naltrexone Injection by Clinical Administration Setting

Vivitrol cannot be self-administered. It has to be injected into a gluteal muscle by a licensed healthcare professional, which means the setting where a patient receives the shot is one of the biggest hidden variables in the total bill. The following table compares the visit and administration costs (medication billed separately, per the sections above) across more than twenty common places patients access this treatment nationally.

Clinical Setting Typical Visit + Administration Cost (Medication Billed Separately) What’s Included Why the Price Differs
Private addiction medicine practice (self-pay) $150 to $600+ Physician visit and injection administration Specialized, boutique-style practices carry higher overhead and often offer faster same-week availability
Solo primary care physician office $100 to $300 Standard office visit plus injection administration fee Lower overhead than a specialist visit, though fewer PCPs stock and administer Vivitrol in-house
Outpatient psychiatric practice $150 to $500 Psychiatric evaluation or follow-up visit, plus injection administration Reflects standard psychiatric visit pricing plus the separate injection fee
Community mental health center $0 to $100, often sliding scale Intake or follow-up visit, injection, case management Publicly funded centers price services on an income-based sliding scale
County behavioral health clinic $0 to $50 Visit and injection, often block-grant subsidized Funded through county and state block grant dollars
Federally Qualified Health Center (FQHC) $20 to $50, sliding scale Visit, injection, sometimes 340B-priced medication Federally required sliding-fee scale based on household income and size
340B-eligible nonprofit clinic $0 to $75 Visit, injection, steeply discounted medication Nonprofit 340B drug pricing passes savings directly to the patient
Hospital outpatient injection or infusion clinic $150 to $400+ in facility fees alone Facility fee, nursing administration, physician oversight Hospitals bill a separate facility fee on top of the clinical service itself
Hospital-adjacent, physician-led detox program $200 to $600+ Physician-supervised administration as part of a coordinated medical program Reflects the added cost of physician-level, rather than RN-level, supervision
University or academic medical center clinic $200 to $500 Teaching-hospital visit and administration fees Academic medical centers typically carry higher facility overhead
State-funded Opioid Treatment Program (OTP) Often free or heavily subsidized Visit, induction, injection Funded through State Opioid Response and Substance Abuse Prevention and Treatment Block Grant dollars
Tribal health center or Indian Health Service site Often free or heavily subsidized for eligible patients Visit and injection Federally funded specifically for eligible Native American and Alaska Native patients
VA medical center (enrolled veterans) $0 to $15 copay tier Visit and injection Veterans Affairs formulary pricing applies
Retail pharmacy-partnered injection site $50 to $200 administration fee Injection only, coordinated through the Vivitrol Provider Locator network Retail partner sites keep administration overhead lower than a full specialist visit
Telehealth-coordinated, in-person injection $75 to $250 combined Virtual prescriber visit plus a separate local injection appointment Splits the visit and injection across two lower-cost touchpoints instead of one bundled specialist visit
Urgent care center $150 to $350 Urgent care visit fee plus injection administration Urgent care pricing typically sits between primary care and emergency department pricing
Intensive outpatient program (IOP) clinic Often bundled into program fee Visit, injection, group and individual counseling Cost is usually absorbed into a broader weekly or monthly program rate
Residential or inpatient rehab facility Bundled into the daily program rate Injection included as part of inpatient medical care Reflects 24/7 staffing and facility costs rather than a stand-alone billed line item
Jail or prison-based reentry MAT program Often free to the individual Induction and injection prior to release Funded through state SOR dollars and corrections department partnerships
Hospital emergency department-initiated induction $500 to $1,500+ in combined facility and physician fees ED visit, physician evaluation, injection Emergency department facility fees bill at a materially higher rate than outpatient visits
Mobile or street medicine outreach program Often free Field-based visit and injection Grant-funded outreach programs are specifically designed to remove cost as a barrier
Specialty infusion or injection center $100 to $300 Injection administration only, medication brought or billed separately Centers specializing in injectable medications keep per-visit overhead lower than a full medical visit

The data reveals that self-pay patients can face a five to tenfold difference in administration cost alone depending on where they go, entirely separate from what they pay for the medication itself. A hospital emergency department and a state-funded OTP clinic can administer the exact same 380mg dose on the exact same day, yet one patient walks away with a bill in the four figures and the other pays nothing. For families comparing options, the setting is often the single biggest lever they have control over.

The Significance of Comparative Data for Naltrexone Injections for Patients and Families

Across every table in this breakdown, one pattern holds. The medication itself, at $1,000 to $2,500 per injection, is only the starting point. Pre-induction testing, the clinical visit, the administration fee, and the setting where care happens each add their own layer of cost, and those layers compound quickly for anyone planning a realistic treatment timeline of 6 to 12 months or longer.

For families weighing options right now, the most useful question usually isn’t “what does the shot cost.” It’s whether testing, induction, the injection itself, and follow-up aftercare can happen under one coordinated plan, instead of being priced and scheduled separately at full retail cost across multiple providers.
