What is Vetsulin Insulin?

Vetsulin® (porcine insulin zinc suspension) is an injectable insulin suspension that reduces hyperglycemia (high blood sugar) in dogs and cats with diabetes mellitus. It's used with U-40 insulin syringes (sold separately). Vetsulin requires a prescription from your veterinarian. Vetsulin Insulin requires refrigeration and must be kept at refrigerator temperatures at all times. To ensure proper temperature, it requires overnight shipping at an additional cost.


Dogs and Cats


  • Controls your pets glucose levels and eases symptoms of diabetes.
  • First and only FDA-approved pet insulin available in the U.S.


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. Insulin requires refrigeration. Rarely, allergic reactions can occur. Seek emergency veterinary care if your pet experiences hives, difficulty breathing, or swelling lips, tongue, or face. If Vetsulin is discontinued or not given as directed, the signs of diabetes will likely return and life-threatening complications such as ketoacidosis may develop.
