If your dog uses Adequan Canine, the refill detail to check is the lot number on the vial or box before the next dose. American Regent, Inc. Animal Health has recalled two lots of Adequan Canine Injection after glass fibers were found during internal retained-sample testing, according to the FDA-posted company announcement. Do not guess, switch medicines or keep using a matching lot because it was expensive. Contact your veterinarian or the pharmacy that supplied it.

Why this matters now

The FDA posted the recall on August 3, 2026, after American Regent announced it on July 31. The dog product involved is Adequan Canine Injection, 100 mg/mL, 5 mL multi-dose vial, a prescription medication used under a licensed veterinarian’s direction for non-infectious degenerative or traumatic joint dysfunction in dogs.

This is not a broad recall of every Adequan product. The FDA notice says the Adequan Canine lots are 3369 and 25011. The company also listed two horse Adequan i.m. lots, but dog owners should focus on the canine vial if they have a dog prescription at home or an active refill with a vet clinic or online pharmacy.

The lot-code check before a refill

Look for the product name, lot number and expiration date before you reorder, accept a refill or use a vial already in the house. The FDA-posted table lists these affected dog lots:

• Adequan Canine Injection, 100 mg/mL, 5 mL multi-dose vial, lot 3369, distributed May 22, 2024, expiration October 31, 2026.
• Adequan Canine Injection, 100 mg/mL, 5 mL multi-dose vial, lot 25011, distributed April 14, 2025, expiration December 31, 2027.

If your refill label covers the manufacturer’s lot number, do not peel, scrape or rely on memory. Call the dispensing pharmacy or veterinary clinic and ask them to verify the manufacturer lot tied to your order. Keep the box, vial and receipt information together until the recall question is resolved.

What to ask the vet or pharmacy

Because Adequan Canine is prescription-only and used under veterinary direction, the safest shopping move is to treat this like a medication refill problem, not a normal pet-supply return. Ask these questions before checkout or before the next dose:

• Can you confirm the manufacturer’s lot number for the vial you dispensed or plan to ship?
• If my product is lot 3369 or 25011, should I return it to you, hold it for replacement instructions or contact American Regent directly?
• Will my refill timing change while the recalled lot is handled?
• Do you need a new prescription authorization, or can the replacement be processed under the current prescription?
• Is there any storage, handling or disposal instruction you want me to follow for this specific vial?

Do not substitute a different joint product, supplement or online listing without your veterinarian’s direction. A cheaper cart is not useful if it disrupts a prescribed treatment plan or creates a new safety question.

Deal and coupon checks before paying

Online pet pharmacies often advertise savings, auto refills or coupon prompts, but prescription medication orders can have extra rules. Chewy’s pharmacy help page, for example, says prescription medications require veterinarian approval before dispensing, approval can take up to three business days, and prescription medications are not accepted for ordinary returns, although incorrect or damaged medication may be handled case by case.

Before you use a promo code on a dog arthritis medication refill, verify the product, lot availability, prescription approval status, shipping timing and replacement policy. If the product page does not show lot numbers, that is normal for many pharmacies, but it means the deal should wait until a pharmacist, clinic or customer-care team confirms the shipment will not come from a recalled lot.

What to avoid

• Do not keep using an affected lot because there have been no reported adverse events. The recall notice says any person or entity with the recalled product lots should not use them.
• Do not assume an old refill is safe because the box looks normal. The FDA notice says the recalled products are clear, colorless to slightly yellow solutions, so appearance alone is not enough.
• Do not buy from a marketplace seller that cannot confirm pharmacy licensing, prescription handling and product source.
• Do not throw away all documentation before asking about replacement, credit or reporting steps.
• Do not make medication changes based on a coupon, social post or search result. Ask your veterinarian.
