Vetsulin overview

Vetsulin® (porcine insulin zinc suspension) from Merck Animal Health is the only FDA-approved veterinary product for the management of diabetes mellitus in both dogs and cats. Vetsulin is indicated for the reduction of hyperglycemia and hyperglycemia-associated clinical signs in dogs and cats with diabetes mellitus.

Vetsulin is supplied as a sterile injectable 40 IU/mL porcine insulin zinc suspension contained in multidose 10 mL vials for use with syringes and multidose 2.7 mL cartridges for use with VetPen®. Vials are sold individually, while 2.7 mL cartridges are supplied in packs of 10.

Intermediate-acting insulin

As a lente insulin, Vetsulin is classified as an intermediate-acting insulin. It is an aqueous suspension of 40 IU/mL of highly purified porcine insulin, consisting of 35% amorphous and 65% crystalline zinc insulin.

Unlike human insulin, porcine insulin has the same amino acid sequence as canine insulin, making it less likely for dogs to develop anti-insulin antibodies.

Not only is the efficacy of Vetsulin proven in clinical trials, Vetsulin also offers veterinary practitioners the added security and confidence that comes from over 20 years of successful use by veterinarians worldwide (under the brand names Vetsulin® and Caninsulin®).
