How to Help Your Patients Save Money on Naltrexone: A Provider's Guide to Savings Programs

Cost is one of the most underappreciated barriers to medication adherence in addiction medicine. A patient may be motivated to take naltrexone, have a supportive prescriber, and have a prescription in hand — but if they can't afford the medication, or if they run out because they can't pay for the refill, the treatment fails.

This guide is for prescribers and care teams: physicians, nurse practitioners, physician assistants, and care coordinators managing patients on naltrexone for AUD or OUD. It covers every major savings option available in 2026, how to determine which option applies to each patient, and how to integrate cost counseling into your prescribing workflow.

Understanding the Cost Landscape

Naltrexone's cost situation is highly stratified by formulation and insurance status:

Generic oral tablets (50 mg): Retail price $88-$168/month without insurance or discount. With GoodRx or SingleCare coupons: as low as $32-$37/month. With commercial insurance (Tier 1-2): typically $0-$30/month copay. With Medicaid: often $0-$5/month.

Vivitrol (380 mg IM monthly): Retail price $1,200-$2,127/month. With commercial insurance and Vivitrol2gether copay program: $0-$5/month for 91% of eligible patients. With Medicare Part D: covered with prior auth, typical copay varies. With Medicaid: covered in most states with prior auth.

The practical implication: most patients on generic naltrexone can access it affordably with the right coupon or coverage. The challenge is making sure every patient knows which option applies to them.

Savings Options by Patient Insurance Status

1. Commercially Insured Patients

Generic oral naltrexone: Covered by virtually all commercial plans, typically at Tier 1 or Tier 2. Copays are usually $0-$30/month. If the copay is higher than expected, check whether the plan requires step therapy (e.g., requiring acamprosate or disulfiram before approving naltrexone). Commercial plans rarely require prior authorization for generic naltrexone.

Vivitrol: The Alkermes Vivitrol2gether copay assistance program is the key tool for commercially insured patients. Under this program: 91% of eligible patients pay $0/injection, and 9 out of 10 pay less than $5. Enrollment is handled through the prescribing provider; visit vivitrol.com/providers or call 1-800-848-4876. The program applies to AUD and OUD indications.

Note: Prior authorization is commonly required for Vivitrol on commercial plans. The documentation needed typically includes diagnosis (F10.xx for AUD or F11.xx for OUD), treatment history, and documentation of medical necessity. Submit PA documentation proactively to avoid delays.

2. Medicare Patients

Generic oral naltrexone is covered under Medicare Part D, typically at Tier 1-2. Copays vary by plan but are generally low. Encourage Medicare patients to use Medicare's plan finder tool to select a plan that covers naltrexone at the lowest copay tier.

Vivitrol for Medicare: Coverage is available under Part D with prior authorization. When Vivitrol is administered in a provider's office, billing under Medicare Part B (as an administered drug) may be an option — consult with your billing team for details. The Vivitrol2gether manufacturer program does NOT apply to Medicare beneficiaries.

Extra Help (Low-Income Subsidy): Medicare patients with limited income may qualify for Extra Help, which can reduce Part D copays to $0-$4 for Tier 1 drugs including generic naltrexone. Refer eligible patients to the Social Security Administration to apply.

3. Medicaid Patients

Generic oral naltrexone is covered by Medicaid in all 50 states. Copays are minimal (typically $0-$5 per fill). Most Medicaid patients on generic naltrexone will pay little to nothing.

Vivitrol for Medicaid: Coverage varies significantly by state. Most states include Vivitrol in their Medicaid formularies, often with prior authorization requirements. Some states require step therapy (patient must have tried and failed oral naltrexone). Medicaid expansion states tend to have broader coverage. Check your state's Medicaid pharmacy benefit manager for current coverage criteria.

Important: The Vivitrol2gether manufacturer copay program cannot be used for Medicaid patients. However, the Patient Access Network Foundation may provide financial assistance for some Medicaid patients facing high cost-sharing.

4. Uninsured or Underinsured Patients

Generic oral naltrexone: Prescription discount cards are the fastest solution. GoodRx brings the price to as low as $32.40/month for a 30-tablet supply. SingleCare offers prices as low as $36.99. These cards require no enrollment and are immediately available online or via app.

Uninsured Vivitrol patients have more limited options. The Patient Access Network Foundation (PAN Foundation, panfoundation.org) offers financial assistance for certain specialty medications. Refer eligible patients there for a determination.

Federally Qualified Health Centers (FQHCs) operate on sliding-fee scales and may access 340B pricing for medications including naltrexone — significantly reducing costs for low-income patients. Connecting uninsured patients with an FQHC near them may be the most effective solution for both medication access and comprehensive addiction care.

Prescribing Strategies That Reduce Costs

Prescribe 90-day supplies: For stable patients, 90-day prescriptions often cost less per unit and reduce copay frequency. Many commercial plans and Medicare Part D allow 90-day fills, especially through mail-order pharmacies.

Direct to mail-order for insured patients: Many plans offer lower copays for mail-order vs. retail pharmacy. Additionally, mail-order supply is more consistent during the current shortage.

Anticipate prior authorizations: For Vivitrol, submit the prior authorization with diagnosis codes and treatment history at the time of prescribing, not after the pharmacy rejection. Proactive PA submissions prevent delays in treatment.

Educate on discount card use: For uninsured patients or those whose copay exceeds the discount card price, counsel them to compare their insurance copay against GoodRx/SingleCare before paying. The cash price with a coupon is sometimes lower than the insurance copay.

Building a Cost-Counseling Workflow in Your Practice

Consider building a simple decision tree for your care team:

Identify insurance status (commercial, Medicare, Medicaid, uninsured/underinsured)

Identify formulation (oral generic 50 mg vs. Vivitrol 380 mg)

Apply the right savings tool: GoodRx for uninsured oral naltrexone; Vivitrol2gether for commercially insured Vivitrol; FQHC/340B for low-income patients; PAN Foundation for uninsured Vivitrol

Resolve prior authorizations proactively for Vivitrol on commercial, Medicare, and Medicaid plans

Help patients locate stock — during the shortage, knowing which pharmacy has naltrexone in stock matters as much as knowing the price

Helping Patients Find Naltrexone in Stock

During the ongoing naltrexone tablet shortage, cost is only one barrier — availability is another. medfinder.com/providers helps clinical teams locate which pharmacies in a patient's area have naltrexone in stock, without the burden of calling each pharmacy individually.
