Merck Animal Health announces Vetsulin

SUMMIT, NJ—April 29, 2013 – Merck Animal Health today announced that Vetsulin® (porcine insulin zinc suspension), the only FDA-approved insulin for use in both dogs and cats is now available to veterinarians throughout the United States. The prevalence of diabetes mellitus in dogs and cats ranges from one in 1001 to one in 500, 2 and the number of dogs diagnosed with the disease has tripled during the past 30 years.3 Today, along with proper diet and exercise, Vetsulin plays an important role in successfully managing diabetes in both dogs and cats.

"We are pleased that Vetsulin is again available in the U.S. market; offering our customers the same product benefits that veterinarians worldwide have relied on for the past 20 years," said Christopher Pappas, D.V.M., Director, Technical Services, Merck Animal Health. "At Merck Animal Health, we are committed to providing our full support to veterinarians as they manage the health of dogs and cats living with diabetes."

While only 50 percent of dogs used to survive the first 60 days following a diagnosis of diabetes mellitus, today, dogs receiving the proper treatment have the same expected lifespan as a non-diabetic dog of the same age and gender. 3 With effective treatment, lifestyle changes and monitoring, a diabetic cat also can have the same expected life span as a non-diabetic cat of the same age.

Getting the disease under control is paramount to survival. In a study of dogs treated with Vetsulin, adequate glycemic control was achieved in an average of 81 percent of dogs, 4 and in a pivotal U.S. study of diabetic cats, Vetsulin reduced all major diabetes indicators to within normal range by day 60 of treatment.5,6

Merck Animal Health is committed to supporting veterinarians in the ongoing treatment of their patients, including making diabetes professionals available to answer questions. An in-depth website (http://www.vetsulin.com) provides tools for both veterinarians and pet owners to make monitoring blood glucose levels easier. A wide variety of pet owner educational materials also can be found on the website, including downloadable guides from step-by-step instructions for giving an insulin injection to a management monitoring sheet to keep track of a pet's progress.

Vetsulin should not be used in dogs or cats known to have a systemic allergy to pork or pork products. Vetsulin is contraindicated during periods of hypoglycemia. Keep out of reach of children. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential to attain and maintain adequate glycemic control and prevent associated complications. Overdosage can result in profound hypoglycemia and death. The safety and effectiveness of Vetsulin in puppies and kittens, breeding, pregnant, and lactating dogs and cats has not been evaluated.
