Merck Expands Banamine/Banamine-S Recall Due to Particulate Matter

Merck Animal Health announced on Friday, September 29 that it has voluntarily recalled an additional four batches of Banamine/Banamine-S (flunixin meglumine injection) 50 mg/mL in the United States to the consumer level due to the presence of particulate matter. This latest step follows a separate Merck recall on September 1, 2023 for three batches of Banamine/Banamine-S Injection for the same reason.

Banamine/Banamine-S is used for injection in cattle, swine, and horses and is a prescription product in the U.S.

The FDA defines particulates as “mobile, undissolved particles (metal, glass, dust, fiber, rubber, polymer, mold, degradant precipitate) other than gas bubbles that are unintentionally present in an injectable product.” Particulates were observed during routine quality testing and reviews for the following batches:

After intravenous administration in large animals, such as cattle or horses, particulate matter could travel to the lungs which could result in local tissue damage.
