Nationwide recall for dog, horse meds

American Regent Inc. Animal Health said on July 31 it was recalling four lots of Adequan injections used in dogs and horses after internal testing found visible glass fiber material in retained samples. The recall applies nationwide and reaches the consumer level, meaning veterinarians, clinics and pet owners are all included in the notice. The U.S. Food and Drug Administration posted the company’s recall notice this week. OregonLive separately reported that owners were being told not to use affected vials and to verify lot numbers before giving the medication. (fda.gov) ### Which medications are actually covered? (fda.gov) The FDA notice says the recall covers two lots of Adequan Canine Injection, 100 mg/mL in 5 mL multi-dose vials, and two lots of Adequan i.m. Injection for horses, 500 mg/5 mL in single-dose 5 mL vials. The affected canine lot numbers are 25011 and 3369. The affected horse lot numbers are 24416 and 25265P. American Regent said the issue was found during testing of internally retained samples, not through a broader product-line failure. The recall notice says only the listed lots are included. (fda.gov) ### What was found in the vials? American Regent said visible glass fiber material was found in the product during routine testing of retained samples. Some secondary reports described the contamination as fiberglass floating in vials, but the FDA-posted recall notice uses the term “glass fibers.” (fda.gov) The FDA notice says particulate material in an injectable product can create a risk when administered. Veterinary trade coverage said the concern is tied to injection-site complications if contaminated product is used. (fda.gov) ### What should pet owners and veterinarians do now? The FDA notice says customers with affected product should stop using it and contact American Regent to arrange returns. OregonLive reported that pet owners should also contact their veterinarian if they think they have an affected vial or if an animal may have received one. (fda.gov) The recall reaches the consumer level, which means clinics and owners should check inventory and stored medication against the listed lot numbers. The manufacturer’s recall notice is the key document because the action does not apply to every Adequan vial in circulation. (fda.gov) ### Have any injuries been reported? American Regent’s recall notice, as reflected in follow-up trade and recall coverage, did not report injuries tied to the affected lots at the time of publication. Some recall summaries said no adverse events had been reported so far. (fda.gov) The absence of reported injuries does not change the recall instructions. The FDA posting says the products are being recalled because of the contamination finding in retained samples. (fda.gov) ### Where can owners verify the lot number? The FDA recall page lists the product names, strengths, vial sizes and lot numbers for the affected shipments. OregonLive said owners and veterinarians should compare any vial they have on hand against that list before use.

The next step for owners with questions is to contact their veterinary clinic or the manufacturer using the information in the FDA recall notice dated July 31, 2026. (fda.gov)
