Why This Recall Matters
American Regent recalled the affected Adequan Canine Injection lots because glass fibers were found during testing of internally retained samples. The product is administered by intramuscular injection and is intended to be used by or under the direction of a licensed veterinarian.
According to the recall notice, administering an intramuscular injectable product containing particulate matter such as glass fibers may cause local irritation, swelling, inflammation, injection-site pain, infection, or abscesses.
The FDA notice does not identify risks to humans handling the product. Pet parents should contact their veterinarian if their pets have experienced any problems that may be related to the use of the recalled product.
