 Vetsulin back on the market

Posted May 15, 2013

Merck Animal Health announced in late April that Vetsulin is available again in the United States.

Vetsulin is the only insulin product that has received approval from the Food and Drug Administration for the treatment of diabetes mellitus in dogs and cats.

In 2009, the FDA announced concerns about Vetsulin’s stability and recommended that veterinarians transition diabetic dogs and cats receiving Vetsulin to other insulin products.

Manufacturer Merck Animal Health, then under the name of Intervet/Schering-Plough Animal Health, initiated the Vetsulin Critical-Need Program for dogs and cats with diabetes difficult to manage with other insulin products. The manufacturer later discontinued the program after tests indicated that bacterial contamination might have compromised a batch of the product.

Merck stated that it has addressed the manufacturing issue that affected the stability of Vetsulin and requalified the product for sale.
