How to Find Naltrexone in Stock Near You (Tools + Tips)

Finding naltrexone at a pharmacy in 2026 is harder than it should be. With an active shortage affecting oral tablet supply since February 2024, patients and their families are spending hours calling pharmacies, only to hear the same thing: "We're out of stock — try somewhere else."

The good news is that naltrexone is not gone from the market. Multiple manufacturers still have product available, and pharmacies receive shipments at different times. The key is knowing how to search efficiently. This guide walks you through the best tools and strategies to find naltrexone in stock near you — without hours of frustrating phone calls.

Step 1: Use medfinder to Call Pharmacies For You

The fastest way to find naltrexone near you is to use medfinder.com. medfinder is a service that calls pharmacies in your area on your behalf to check which ones can fill your prescription. You provide your medication name, dosage, and location, and medfinder texts you the results — typically within hours.

This is especially valuable during a shortage, when you need to check a wide area efficiently. Instead of spending your morning on hold, medfinder does the calling for you.

Step 2: Don't Limit Yourself to Chain Pharmacies

During the naltrexone shortage, availability varies enormously from one pharmacy to the next. Many patients assume their CVS or Walgreens is representative of what's available everywhere — but that's not true. Independent pharmacies, grocery chain pharmacies (like Kroger or Publix), and big-box retailers (like Costco and Walmart) often carry different stock from the major national chains.

Cast a wide net. If your usual pharmacy is out, check:

Independent and locally-owned pharmacies in your area

Grocery store pharmacy counters (Kroger, Publix, Safeway, HEB, etc.)

Warehouse club pharmacies (Costco and Sam's Club often have different supply chains)

Mail-order pharmacies (for long-term supply — ask your insurer which one they work with)

Step 3: Ask Your Pharmacy to Order From a Different Manufacturer

Naltrexone is made by several generic manufacturers. Accord Healthcare, Major Pharmaceuticals, and Sun Pharma have reported available stock, while others like Avet and Tagi Pharma have discontinued their products. When you call a pharmacy, ask them specifically whether they can order naltrexone from a different generic manufacturer or through a secondary wholesaler. Some pharmacies can source from multiple suppliers and may be able to get stock within a few days.

Step 4: Talk to Your Prescriber About Alternatives

If oral naltrexone tablets are truly unavailable in your area, your prescriber has options:

Vivitrol (injectable naltrexone): The 380 mg monthly injection is not affected by the tablet shortage. If your insurance covers it, this may be a seamless transition.

Compounding pharmacy: A compounding pharmacy can prepare naltrexone in capsule, liquid, or other formats. This can be especially useful for patients on low-dose naltrexone (LDN).

Medication bridge: For AUD patients, your provider may recommend a short-term bridge strategy while you work to locate your regular supply.

Step 5: Use Price Comparison Tools to Find Participating Pharmacies

Tools like GoodRx and SingleCare don't show real-time inventory, but they do show which pharmacies in your area participate in their discount programs and are actively filling naltrexone prescriptions. If GoodRx shows a price at a particular pharmacy, that pharmacy is likely actively stocking the medication or recently has been.

Use this as a starting point for your search, then call ahead to verify stock before making the trip.

Step 6: Check Mail-Order Options

If you take naltrexone for long-term maintenance (which is common for AUD treatment), a mail-order pharmacy may be the most reliable way to ensure consistent supply. Mail-order pharmacies often have direct relationships with manufacturers and may have better inventory access than retail pharmacies. Check with your insurance provider about which mail-order pharmacies are in-network for your plan.

Tips to Avoid Running Out of Naltrexone

Request refills early. Don't wait until your last few pills to start looking for your next supply. Start your search at least 10-14 days before you run out.

Ask for a 90-day supply. When you do find stock, ask your prescriber to authorize a 90-day supply. This builds a buffer against future shortages.

Identify a backup pharmacy. Know which other pharmacies in your area regularly stock naltrexone so you have a fallback if your primary pharmacy runs out.

Stay in touch with your care team. Your prescriber may have access to shortage updates, compounding resources, or samples that can help bridge a gap.
