Naltrexone Without Insurance: Full Price Breakdown

You've got a prescription for naltrexone and no insurance card to hand over at the pharmacy. That's a more common situation than you'd think, and the good news is that the generic tablets are one of the cheaper scripts you'll come across. The less obvious part is everything else that adds to the bill: consult fees, lab panels, shipping charges. Here's what the full monthly picture actually looks like when you're paying cash.

TLDR:

• Generic naltrexone 50 mg runs $25 to $100 for a 30-day supply without insurance, with Cost Plus Drugs pricing around $23
• Vivitrol injections cost $1,200 to $2,500 per month out of pocket, and no generic version exists
• Factor in provider visits, lab work, and pharmacy fees: realistic self-pay treatment runs $75 to $200 per month total
• Free discount cards from GoodRx, RxSaver, or SingleCare cut oral naltrexone costs at most chain pharmacies with no insurance needed
• Onir bundles naltrexone 50 mg, clinician consultations, and ongoing care into a flat $99/month for self-pay patients

Oral Naltrexone 50 mg: Retail Cost Without Insurance

If you're paying out of pocket, generic naltrexone 50 mg is one of the more affordable prescription medications you'll encounter. According to Drugs.com, a 30-tablet supply runs about $32.24, though your final price depends on which pharmacy you use and where you live.

The range is wider than you might expect. Addiction Center reports that oral generic naltrexone runs $25 to $100 without insurance. Buying a 90-day supply at once tends to bring the per-tablet cost down, while smaller quantities at certain chain pharmacies can push you toward the higher end. Geography matters too: the same medication can cost noticeably more at a pharmacy in Manhattan than one in rural Ohio.

Vivitrol (Injectable Naltrexone): Cost Without Insurance

Vivitrol is a different animal entirely. The injectable form of naltrexone, sold only under the brand name Vivitrol, delivers 380 mg once a month and must be administered by a healthcare provider. No generic version exists, which keeps prices high.

Without insurance, Vivitrol can range from $1,200 to $2,500 per month, and that figure doesn't include the cost of the clinic visit where you actually receive the shot. Between the office fee and the medication itself, a single month of treatment can easily clear $1,500 or more out of pocket.

Why the steep jump from a $32 bottle of tablets? Three reasons: Vivitrol is a brand-name product with no generic competition, the extended-release formulation is more complex to manufacture, and every injection requires an in-person appointment with a provider who bills separately for their time.

Naltrexone Cost With Insurance and Medicare

Most commercial insurance plans cover generic oral naltrexone, and copays typically land under $25 for a 30-day supply, partly because naltrexone isn't a controlled substance. Medicare Part D includes it on most formularies, and the majority of state Medicaid programs do as well. If you have any form of prescription coverage, oral naltrexone is unlikely to be a budget problem.

Vivitrol's coverage picture is surprisingly broad too. According to a 2024 manufacturer disclosure, 99% of insured patients were covered for the injectable, including those on Medicaid, though that figure isn't a guarantee of current coverage or affordability. That said, "covered" and "affordable" aren't always the same thing. Your actual out-of-pocket cost depends on your plan's formulary tier, deductible status, and whether the injection is billed under medical or pharmacy benefits.

Even with good coverage, prior authorization requirements or step therapy rules can delay access. Some plans require you to try oral naltrexone before they'll approve Vivitrol. Plan formularies also change annually, so checking with your insurer before filling is always a smart move.

Why Low Dose Naltrexone Costs Differently

Low dose naltrexone, usually prescribed between 1.5 mg and 4.5 mg, sounds like it should cost less than the standard 50 mg tablet. It doesn't always work out that way.

No manufacturer sells naltrexone in doses that low, so a compounding pharmacy has to prepare custom capsules from the raw ingredient. That labor and specialized equipment drive the price. Expect to pay $30 to $80 for a 30-day supply depending on the pharmacy, with mail-order compounders typically running closer to the low end.

Insurance almost never covers LDN because the low-dose use is off-label and the medication is compounded instead of commercially manufactured. Most insurers exclude compounded drugs from their formularies entirely.

If your prescriber recommends LDN, the LDN Research Trust maintains a directory of compounding pharmacies where you can compare prices. Worth noting: Onir prescribes the standard FDA-approved 50 mg tablets for alcohol use, not compounded LDN.

Factors That Affect Naltrexone Pricing

Several variables explain why the price you see at one pharmacy rarely matches the quote from another.

• Formulation: oral tablets versus the Vivitrol injection represent the biggest cost split, but even within oral naltrexone, branded Revia costs more than its generic equivalent.
• Pharmacy type: retail chains like CVS and Walgreens often price higher than mail-order or online alternatives such as Cost Plus Drugs.
• Geographic region: pharmacies in high cost-of-living areas tend to charge more for the same generic medication. A zip code change can swing the price by $20 or more on a single fill.
• Supply quantity: a 90-day fill almost always brings the per-unit cost down compared to filling 30 tablets at a time.
• Discount cards and coupons: applying a GoodRx coupon or similar savings card at checkout can cut the cash price, but the discount varies by pharmacy and changes frequently.

If you're self-pay, checking prices across two or three options before filling is worth the five minutes it takes.

Pharmacy Price Comparison: Walmart, CVS, GoodRx, and Cost Plus Drugs

Here's how approximate pricing shakes out for a 30-tablet supply of generic naltrexone 50 mg at some of the most commonly searched pharmacies.

These figures come from GoodRx listing pages and reflect coupon-assisted pricing, which fluctuates. Your actual total at checkout could be a few dollars higher or lower depending on your location and the day you fill.

Cost Plus Drugs consistently comes in cheapest because their model adds a flat 15% markup to the manufacturer's cost plus a dispensing fee, skipping the opaque middleman pricing that inflates retail pharmacy numbers, which matters whether you're managing costs or just learning about drinking on naltrexone. The trade-off is that it's mail-order only, so you'll wait a few days for delivery instead of picking up same-day.

Coupons, Discount Cards, and Patient Assistance Programs

Discount cards are the easiest win for oral naltrexone. GoodRx, RxSaver, and SingleCare all offer free coupons that work at most chain pharmacies, and they're built for cash-pay patients. No insurance needed. Just pull up the coupon on your phone at checkout.

If you're on Vivitrol, the savings picture looks different. The Vivitrol Co-pay Savings Program covers up to $500 per month toward copay expenses, and according to Vivitrol's 2025 claims data, 88% of eligible patients had no out-of-pocket costs. The catch: you need commercial insurance to qualify. Patients on Medicaid, Medicare, or other government plans are excluded, and so are uninsured patients paying cash.

For people without any coverage, SAMHSA's National Helpline (1-800-662-4357) offers free, confidential referrals to local treatment programs that may provide naltrexone at reduced or no cost.

The short version: oral naltrexone discount cards work for almost anyone paying cash, while most Vivitrol assistance programs assume you already have insurance.

How to Get a Naltrexone Prescription Online

Naltrexone is a prescription medication, so you can't buy it over the counter or order it from an overseas pharmacy and call it a day. A licensed clinician has to review your medical history and confirm the medication is appropriate before writing the script.

Telehealth has made getting naltrexone prescribed online considerably faster than booking an in-person appointment. Most online services follow a similar flow: you complete a medical intake form, a clinician reviews it, and if approved, the prescription gets sent to a pharmacy. The whole thing can happen without a video call, depending on the service, and many operate on a self-pay basis, so insurance isn't required.

One requirement applies everywhere: your prescriber needs to confirm you haven't used opioids in the past 7 to 10 days. That's one reason timing your naltrexone dose correctly matters from day one. Naltrexone blocks opioid receptors, and taking it while opioids are still in your system triggers severe withdrawal. Any reputable telehealth provider will ask about this upfront.

For self-pay patients, online prescribing services often bundle the consultation fee and medication into a single price, which can simplify budgeting compared to juggling separate provider and pharmacy bills.

The Hidden Costs of Naltrexone Treatment

The sticker price on a bottle of naltrexone tells you what the pills cost. It doesn't tell you what treatment costs.

Most providers charge separately for the initial consultation, with fees ranging from $50 to $250 depending on whether you see someone in person or through a telehealth service. Follow-up visits add up too, especially if your provider wants monthly check-ins, which ties into the broader question of how long to take naltrexone. Some clinicians require baseline liver function tests before prescribing, since naltrexone carries a rare risk of hepatotoxicity, and periodic re-testing after that. A basic liver panel runs $20 to $100 at a cash-pay lab, more at a hospital outpatient facility.

Then there's the pharmacy side. Mail-order services may tack on shipping fees or processing charges that don't show up until checkout. If you're filling at a retail pharmacy, you're spending gas and time on monthly trips. None of these line items appear when you search "naltrexone price," but they're real dollars leaving your account.

For someone budgeting the full monthly picture on self-pay, a reasonable estimate for oral naltrexone treatment is $75 to $200 per month once you layer in the medication, provider fees, and any required lab work.

Common Naltrexone Side Effects and What They Cost You

Most people experience mild side effects when they first start naltrexone: nausea, headache, and fatigue are the usual trio. They tend to fade within the first week or two as your body adjusts, and taking the tablet with food cuts down on naltrexone nausea and side effects considerably.

The financial upside here is that these common reactions rarely warrant an extra doctor's visit. You're unlikely to need a prescription for anti-nausea medication or an urgent care trip because you felt sluggish for a few days. For self-pay patients watching every line item, that matters. The side effects are real, but they're generally short-lived enough that they don't add to your treatment costs in any meaningful way.

How Onir Simplifies Naltrexone Access and Pricing for Self-Pay Patients

We built Onir around the exact problem this article keeps circling: when you're paying out of pocket, the real cost of naltrexone treatment is scattered across provider fees, pharmacy prices, follow-up visits, and shipping charges that are hard to predict before you start.

Onir bundles all of it into one number. The subscription runs $99 a month, billed as $297 every 90 days, covering FDA-approved generic naltrexone 50 mg tablets, clinician consultations, prescription management, and ongoing care team support. A $19.99 clinician review kicks things off, refunded in full if you're not approved.

Consultations happen through secure, asynchronous text-based chat with a licensed clinician, usually within 24 hours, so you can start tracking the naltrexone work timeline right away. No video calls, no waiting rooms. Medication ships in unmarked packaging, and because Onir is self-pay, there's no insurance claim record. We're available in all 50 states.

The practical difference? One predictable charge instead of three or four separate bills to track down every month.

Final Thoughts on Naltrexone Pricing

A bottle of generic naltrexone 50 mg is one of the cheaper prescriptions you can fill. The part that catches people off guard is everything around it: provider visits, lab work, follow-ups. Know your full monthly number before you start, and the rest gets simpler from there.

FAQ

What's the cheapest way to get naltrexone without insurance?

Cost Plus Drugs typically offers the lowest cash price for generic naltrexone 50 mg at around $23 for a 30-day supply, since their pricing model skips the middleman markup common at retail chains. If you prefer picking up in person, applying a free GoodRx or SingleCare coupon at Walmart or CVS brings the price to roughly $35–$36 for the same supply. For a bundled option that includes clinician care and medication together, Onir runs $99 a month (billed as $297 every 90 days).

How do I get naltrexone prescribed online without seeing a doctor in person?

Most telehealth services follow the same basic flow: you complete a medical intake form online, a licensed clinician reviews it (often within 24 hours), and if approved, the prescription goes straight to a pharmacy. No video call or office visit is required with many providers, including Onir, where consultations happen through secure asynchronous messaging. The one universal requirement is confirming you haven't used opioids in the past 7–10 days, since naltrexone blocks opioid receptors and taking it too soon triggers severe withdrawal.

Best telehealth services for alcohol treatment that accept no insurance?

Several telehealth options serve self-pay patients seeking naltrexone for alcohol use, including Oar Health, Ria Health, and Onir. The main differences come down to pricing structure and what's included: some charge separately for consultations, medication, and follow-ups, while Onir bundles clinician care, prescription management, and FDA-approved naltrexone 50 mg tablets into a single $99/month charge. Because all three operate on a self-pay basis, there's no insurance claim record, which matters if privacy is a concern.

Why isn't low dose naltrexone covered by insurance?

LDN (typically 1.5–4.5 mg) isn't commercially manufactured at those doses, so it must be prepared by a compounding pharmacy. Most insurers exclude compounded drugs from their formularies outright, and the low-dose prescribing is off-label, which gives plans a second reason to deny coverage. Expect to pay $30–$80 per month out of pocket, with mail-order compounding pharmacies generally running closer to the lower end.

How much does naltrexone really cost per month when you add in doctor visits and lab work?

The pill itself can run as low as $23–$36 for a 30-day supply at a cash-pay pharmacy, but that number doesn't include provider consultations ($50–$250 for an initial visit), follow-up appointments, or baseline liver function tests ($20–$100 at a cash-pay lab). A realistic all-in estimate for self-pay oral naltrexone treatment is $75–$200 per month. Onir collapses those separate line items into one predictable $99/month subscription that covers medication, clinician consultations, and ongoing support.

Can I use my HSA or FSA card to pay for naltrexone treatment?

Yes. Many pharmacies and telehealth services accept HSA and FSA cards for naltrexone. Onir accepts both HSA and FSA cards at checkout, covering the $19.99 clinician review and the $297 per 90-day subscription.

Vivitrol injection vs oral naltrexone tablets: which one costs less out of pocket?

Oral generic naltrexone 50 mg is far cheaper, running $25 to $100 per month without insurance. Vivitrol injections cost $1,200 to $2,500 per month with no generic available, plus you pay separately for the in-person clinic visit where the shot is administered.

How much is naltrexone with insurance at a typical pharmacy?

With commercial insurance, copays for generic oral naltrexone usually land under $25 for a 30-day supply. Medicare Part D and most state Medicaid programs also cover it, though your exact cost depends on your plan's formulary tier and deductible status.

What does naltrexone 50 mg actually do for alcohol use?

Naltrexone 50 mg blocks the opioid receptors that carry the endorphin reinforcement your brain releases when you drink. Over time, this weakens the automatic pull toward alcohol, and most people notice the shift within 7 to 14 days. It's FDA-approved, non-addictive, and non-habit-forming.

Should I buy naltrexone 90 days at a time or fill it monthly?

A 90-day fill almost always brings the per-tablet cost down compared to filling 30 tablets at a time. If you're paying cash and know you'll be on the medication for a few months, buying in bulk saves money at most pharmacies and through mail-order services like Cost Plus Drugs.

Is there a free Vivitrol shot program near me if I have no insurance?

The Vivitrol Co-pay Savings Program helps with copays but requires commercial insurance to qualify; uninsured patients are excluded. For no-cost options, call SAMHSA's National Helpline at 1-800-662-4357 for free, confidential referrals to local programs that may provide naltrexone at reduced or no cost.

How much does a Vivitrol injection cost per month with insurance?

Vivitrol's manufacturer reports that 99% of people with any insurance, including Medicaid, have some coverage for the injection. With the Vivitrol Co-pay Savings Program, 88% of eligible commercially insured patients had zero out-of-pocket costs in 2025, though prior authorization or step therapy requirements may apply depending on your plan.

Can I get naltrexone at Walmart or CVS without a prescription?

No. Naltrexone is a prescription medication at every pharmacy, including Walmart and CVS. You need a licensed clinician to review your medical history and write the script first. With a prescription in hand, a 30-tablet supply runs roughly $35 at Walmart or $36 at CVS when you apply a free GoodRx coupon.

What happens if I'm taking opioids and try to start naltrexone?

Naltrexone blocks opioid receptors, so taking it while opioids are still in your system triggers severe, immediate withdrawal. Every reputable prescriber will require you to confirm you haven't used opioids in the past 7 to 10 days before writing a naltrexone prescription.

Does naltrexone show up on my insurance record or get reported to my employer?

If you use insurance to fill naltrexone, a claim record will exist on your insurance file, though substance use treatment records carry extra federal protections under 42 CFR Part 2 that restrict sharing. Self-pay services like Onir create no insurance claim at all, and patient data is never shared with an employer.
