FDA Recall: American Regent, Inc. Animal Health Adequan Canine Injection and for Visible glass fiber material in the product

American Regent, Inc. Animal Health • August 03, 2026

FDA Recall: American Regent Adequan Canine & Adequan i.m. Injections for Glass-Fiber Contamination

Need-to-know: American Regent, Inc. Animal Health has voluntarily recalled two lots of Adequan Canine and two lots of Adequan i.m. injections after in-house testing revealed visible glass fibers floating in some vials. If your bottle matches an affected lot, stop using it immediately, quarantine the product, and contact your veterinarian for next steps.

Why the Adequan recall was issued

Retained-sample testing detected glass-fiber fragments in select vials. Injecting particulate matter can trigger local irritation, swelling, infection, or abscess formation at the injection site in dogs or horses. Although no injuries have been reported, the company and the U.S. Food & Drug Administration (FDA) initiated the recall out of an abundance of caution.
